DETAILED DESCRIPTION OF THE INVENTION

(10) FIG. 1 shows a secure value bearing indicia using transparent or translucent (collectively referred to herein as clear) media according to embodiments of the present invention. Embodiments of the secure value bearing indicia on clear media provide value bearing indicia in the form of fungible indicia in that any of a plurality of such indicia may be used interchangeably and thus are not limited to use in a particular transaction, with respect to a particular object, etc. For example, secure value bearing indicia on clear media provided according to embodiments of the invention may comprise fungible postage indicia suitable for use at any time with any postal item. Such clear fungible postage indicia provide fungible value bearing indicia similar to that of postage stamps. In contrast, typical information based postage indicia provided through use of a personal computer postage metering system would not be fungible due to the indicia each being uniquely tied to a particular postal item and it bearing a date corresponding to its date of posting. Similarly, typical postage meter indicia provided through the use of a postage meter system would not be fungible due to the indicia bearing a date corresponding to its date of posting.

(11) It should be appreciated that, although embodiments are described herein with reference to the value bearing indicia comprising postage indicia, value bearing indicia provided according to the concepts herein may be utilized with respect to transactions other than postal services. For example, secure value bearing indicia on clear media provided according to embodiments of the invention may be utilized with respect to tickets, coupons, remittances, etc.

(12) Referring still to FIG. 1, clear fungible postage indicium 100 of the illustrated embodiment is shown comprising clear medium 110 having various markings thereon. The markings shown with respect to clear fungible postage indicium 100 of the illustrated embodiment, for example, include human readable information 101, machine readable information 102, markers 103a and 103b, medium code 104, and aesthetics 105. Such markings, or portions thereof, may be provided for validation of the funds borne by the indicia, security, identification, information, instruction, etc.

(13) Human readable indicia information 101 may comprise various information useful to a user of the indicium, a service provider processing the indicium, and/or other persons likely to be exposed to the indicium. For example, human readable indicia information 101 of the illustrated embodiment includes value amount, postage designation, postage class, meter number, and meter zip code.

(14) Machine readable information 102 may comprise various information, provided in a machine readable format, useful to automated systems handling the indicium, such as mail processing systems, indicia validation systems, electronic commerce systems, and/or other systems likely to be exposed to the indicium. For example, machine readable information 102 of the illustrated embodiment comprises a two dimensional bar code providing robust (e.g., error correcting) encoding of information (e.g., on the order of 20-40 bytes) in a format which is readable by optical scanners. The machine readable information may comprise, for example, value amount, postage class, meter number, authentication information (e.g., digital signature), and/or other information useful in processing the indicium. According to embodiments of the invention, machine readable information 102 comprises a reduced content information based indicia (referred to as IBI light) as shown and described in U.S. patent application Ser. No. 11/729,148 entitled Computer-Based Value-Bearing Item Customization Security, the disclosure of which is incorporated herein by reference.

(15) Markers 103a and 103b may comprise various forms of marks to prevent the copying and reproduction of fungible postage indicia (e.g., using xerographic equipment or computer-based scanner equipment). For example, marker 103a may comprise one or more mark imprinted using a special ink which is invisible under natural light, but which fluoresce under light of a particular wavelength (e.g., ultraviolet light), thereby rendering reproduction of clear fungible postage indicium 100 by typical copying techniques ineffective. Additionally or alternatively, marker 103b may comprise one or more mark imprinted using a special ink which visually appears to have different characteristics (e.g., change color), such as thermo-chromatic inks, thereby rendering reproduction by typical copying techniques ineffective. Because clear fungible postage indicium 100 of embodiments is adapted to provide a value bearing indicia in a form which may be unobtrusively applied to a host object (e.g., a postal item) without substantially impacting the aesthetic appeal of the host object and without substantial risk of improper reuse or copying of the value bearing indicia, embodiments of the invention may utilize, the aforementioned invisible inks rather than inks which visually appear to have different characteristics. It should be appreciated that markers 103a and/or 103b may comprise a simple mark (e.g., the presence of which is simply detected or not), a more complex mark (e.g., a facing identification mark or other mark providing relatively simple information such as postal item face orientation), or an informational mark (e.g., barcode or other rich information carrying mark) according to embodiments of the invention.

(16) Medium code 104 may comprise various information useful in creating and/or validating clear fungible postage indicium 100. For example, medium code 104 may comprise a medium serial number used in controlling the generation of clear fungible postage indicium 100. Such a medium serial number and/or other contents of medium code 104 may be encoded into machine readable indicia information 102, such as for use in validating clear fungible postage indicium 100. The use of serial numbers, as may comprise medium code 104, for controlling the generation of fungible postage indicia is shown and described in U.S. Pat. No. 7,191,158 entitled System and Method for Providing Computer-Based Postage Stamps, the disclosure of which is incorporated herein by reference. It should be appreciated that medium code 104 of embodiments may be adapted to provide security features in addition to or in the alternative to the aforementioned use in creating and/or validating clear fungible postage indicium 100. For example, medium code 104 may be adapted to provide indication of tampering with or reuse of an otherwise valid clear fungible postage medium, such as using adhesive patterning techniques described below.

(17) Aesthetics 105 may comprise various marks, information, etc. provided for aesthetic purposes. For example, aesthetics 105 may comprise logos of a service provider facilitating generation of clear fungible postage indicium 100, a postal service provider, an entity for which clear fungible postage indicium 100 was generated, etc. It should be appreciated that aesthetics 105 may be utilized for purposes in addition to or in the alternative to mere aesthetic ornamentation. For example, aesthetics 105 may include greetings, advertisements, or other messages. Likewise, aesthetics 105 may be adapted to provide security attributes, such as through imprinting aesthetics 105 using special inks as described above, using adhesive patterning techniques described below, etc. For example, aesthetics 105 may be printed using special inks, such as the florescent or thermo-chromatic inks discussed above, for providing security with respect to clear fungible postage indicium 100.

(18) Clear fungible postage indicium 100 may be created by a user for later use in posting postal items as needed. For example, a user may utilize computer system 240 shown in FIG. 2A to create clear fungible postage indicium 100 as one of a plurality of clear fungible postage indicia. Specifically, clear fungible postage indicium 100 may be printed upon sheet 200 along with other clear fungible postage indicia for use at any time and with any postal item by the user. As needed, one or more clear fungible postage indicia may be removed from sheet 200 and applied to a postal item, such as postal item 201, for posting. The clear fungible postage indicia may be adhered to a carrier (shown as carrier 210) of sheet 200 using a pressure sensitive adhesive (e.g., a clear permanent acrylic dispersion adhesive such as RP37 available from UPM Raflatac, Inc.) which allows the clear fungible postage indicia to be removed from the carrier and adhered to a face of a host object, such as postal item 201. For example, carrier 210 may be provided with a coating which reduces the adhesive bond allowing clear fungible postage indicium 100 to be removed relatively easily from the carrier, while postal item 201 has no such coating thereby resulting in a relatively strong adhesive bond between clear fungible postage indicium 100 and postal item 201. FIG. 2B shows an elevation view of a clear fungible postage indicium as disposed upon carrier 210 according to embodiments, wherein adhesive 211 present upon a back surface of the clear medium holds the clear fungible postage indicium to carrier 210 for handling (e.g., printing, storing, etc.) prior to removal and application upon a host object (e.g., postal item 201). FIG. 2C shows an elevation view of the clear fungible postage indicium of FIG. 2B as placed upon postal item 201, wherein adhesive 211 present upon the back surface holds the clear fungible postage indicium to postal item 201.

(19) System 240 used to generate clear fungible postage indicium herein may comprise a processor (e.g., a processor from the CORE processor family available from Intel Corporation), memory (e.g., random access memory (RAM), read only memory (ROM), disk memory, optical memory, flash memory, and/or the like), and suitable input and output functionality (e.g., display, keyboard, digital pointer, printer, microphone, speaker, scanner, touch screen, biometric sensor, and/or the like) operable under control of an instruction set (e.g., operating system, application program, applet, etc.) providing for the generation of clear fungible postage indicia herein. System 240 may communicate with server system 220, such as via network 230 (e.g., a local area network (LAN), a wide area network (WAN), the Internet, the public switched telephone network (PSTN), a wireless network, and/or the like), for obtaining postage value to be included in the value bearing indicia, to generate the value bearing indicia, etc. Additional detail with respect to the generation of fungible postage indicia is shown in U.S. Pat. No. 6,939,062 entitled System and Layout for Proper Printing of NETSTAMPS and Other Labels and U.S. Pat. No. 7,083,345 entitled Roll Label Layout and System for Proper Printing of NETSTAMPS, previously incorporated by reference.

(20) Sheet 200 of the illustrated embodiment comprises carrier 210 upon which a plurality of transfer areas are provided for separation and use as value bearing indicia. For example, a plurality of postage stamp sized transfer areas made from a plastic medium (e.g., polyethylene, polypropylene, polystyrene, vinyl, polyester, etc.) giving a desired level of transparency/translucency may be provided upon carrier 210 for printing upon by a printer (e.g., laser printer, inkjet printer, thermal transfer printer, dot matrix printer, etc.) of system 240 for providing clear fungible postage indicia herein. Sheet 200 and/or the transfer sections thereon may be preprinted or otherwise pre-provided with one or more portions of a completed clear fungible postage indicia according to embodiments of the invention. For example, transfer sections of sheet 200 may be pre-provided with all or a portion of human readable information 101, medium code 104 and/or aesthetics 105. Printing of the remaining portions of the clear fungible postage indicia may be provided by a printer of system 240, perhaps in cooperation with or under control of server 220, to complete the clear fungible postage indicia.

(21) It should be appreciated that although a sheet having a plurality of transfer sections for creating clear fungible postage indicia is shown, embodiments are not limited to the use of sheets or even configurations in which a plurality of clear fungible postage indicia are created at any particular time. For example, embodiments of the invention may utilize a carrier in the form of a roll, such as may be utilized in a label printer or other continuous web printer.

(22) Clear media utilized in clear fungible postage indicia of embodiments of the invention may present a relatively resilient membrane which is resistant to tearing, delaminating, and other destructive forces. Accordingly, the use of clear media for fungible postage indicia presents an increased risk that the clear fungible postage indicia may be reused if not otherwise adapted to discourage such reuse. Clear fungible postage indicia of embodiments of the present invention are adapted to include one or more security features to prevent or otherwise discourage reuse and/or copying of such fungible postage indicia borne on clear media.

(23) Embodiments of the invention provide clear fungible postage indicia having one or more controlled cut in the surface of the clear media to facilitate the destruction of the clear fungible postage indicia when removal is attempted after affixing to a host object. Controlled cuts utilized according to embodiments of the invention may comprise perforation lines, score lines, or combinations thereof. For example, perforation line 310 shown in FIGS. 3A (plan view) and 3B (elevation view) as comprising a plurality of discrete cuts fully penetrating clear medium 110 (e.g., penetrating clear medium 110 to carrier 210) interleaved with a plurality uncut portions of clear medium 110, may be utilized as a controlled cut for facilitating destruction of clear fungible postage indicia according to embodiments of the invention. Additionally or alternatively, score line 410 shown in FIGS. 4A (plan view) and 4B (elevation view) as comprising a cut line partially penetrating clear medium 110 (e.g., not penetrating clear medium 110 to carrier 210) leaving some portion of clear medium 110 uncut, may be utilized as a controlled cut facilitating destruction of clear fungible postage indicia according to embodiments of the invention.

(24) Controlled cut configurations of embodiments of the invention present sufficient structural integrity for printing of the clear fungible postage indicia (e.g., passing through a printer of computer system 240) and their initial application to a host object (e.g., removal from carrier 210 and application upon postal item 201) while introducing areas of diminished structural integrity adapted to facilitate destruction or otherwise disabling the clear fungible postage indicia when removal from a host object (e.g., subsequent removal from postal item 201 after application thereto, perhaps after a period of time sufficient for an adhesive of the indicium to set) is attempted. Embodiments of the invention adapt attributes of the controlled cuts for characteristics of the clear fungible postage indicia, such as characteristics of the clear media (e.g., the tearing strength, the shear strength, the resilience, the dimensional stability, etc.), characteristics of the adhesive (e.g., the strength, the areas of application, the resilience, etc.), and/or the printing (e.g., the areas of printing, the types of ink used, the type of printing technique used, etc.).

(25) It should be appreciated that an adhesive, such as adhesive 211 shown in FIGS. 3B and 4B, may be present between clear medium 110 and carrier 210. For example, a thin film of adhesive, whether in a solid sheet, in a particular pattern, and/or having various adaptations as desired for providing operation herein, may be present upon a back face of clear medium 110. Such an adhesive layer may or may not be penetrated by controlled cuts of embodiments herein, depending upon the particular structural and security characteristics sought. The adhesive may hold clear medium 110 on carrier 210 for generation (e.g., printing) of clear fungible postage indicium 100 and subsequent handling by a user, while allowing separation of carrier 210 from clear medium 110 without appreciable damage thereto for application of clear fungible postage indicium 100 to a host object, such as postal item 201. The adhesive may thereafter fasten clear fungible postage indicium 100 to a host object, such as postal item 201, sufficiently to deter removal and reuse of the indicium using security attributes of embodiments of the invention. For example, the adhesive may be a clear pressure sensitive adhesive, such as the RP37 clear permanent acrylic dispersion adhesive available from UPM Raflatac, Inc., which sufficiently sets within 24 hours of application to an intended host surface to discourage removal and reuse of the indicium.

(26) The ratio of the perforations (i.e., the ratio of perforation cut length (A in FIG. 3A) to remaining web length (B in FIG. 3A)) is adapted according to embodiments of the invention for the attributes of the clear medium and/or adhesive used in order to provide suitable security. For example, where the clear medium comprises a thin polyester film, which provides a relatively resilient membrane having good dimensional stability, a perforation ratio of less than 1 (i.e., B/A<1, or less than 50% media remains in the perforation line, and thus more than 50% of the media is cut through) may be used to facilitate destruction of clear fungible postage indicia when removed from a host object. The perforation ratio where the clear medium is more resistant to tearing, however, may be lower (i.e., B/A<0.25, or less than 20% media remains in the perforation line, and thus more than 80% of the media is cut through) to provide sufficient structural integrity for printing of the indicia and/or their initial application to a host object.

(27) The depth of score lines (i.e., the ratio of the depth of a scoring cut (X in FIG. 4B) to depth of web remaining uncut (Y in FIG. 4B)) is adapted according to embodiments of the invention for the attributes of the clear medium and/or adhesive used in order to provide suitable security. For example, where the clear medium comprises a thin polyester film, which provides a relatively resilient membrane having good dimensional stability, a score depth of more than 50% (i.e., X/Y>1, or less than 50% media remains uncut in the score line, and thus more than 50% of the media is cut through) may be used to facilitate destruction of clear fungible postage indicia when removed from a host object. The score depth where the clear medium is more resistant to tearing, however, may be more than 66% (i.e., X/Y>2, or less than 33% media remains in the score line, and thus more than 66% of the media is cut through) to provide sufficient structural integrity for printing of the indicia and/or their initial application to a host object.

(28) It should be appreciated that embodiments of the invention may utilize controlled cuts implementing a combination of the aforementioned perforation lines and score lines. For example, an embodiment of the invention may utilize one or more perforation line with respect to one area of a clear fungible postage indicium and one or more score line with respect to another area of the clear fungible postage indicium. Moreover, the scoring technique may be utilized with respect to a perforation line, whereby in addition to a perforation ratio a score depth less than the full depth of the clear media is implemented (e.g., the perforation cuts shown in FIG. 3A are scored as shown in FIG. 4B). Such a hybrid scored perforation line configuration may be useful with respect to relatively fragile clear media to provide sufficient structural integrity for printing of the indicia and/or their initial application to a host object, for example.

(29) Attributes of the controlled cuts adapted for characteristics of the clear fungible postage indicia may comprise features in addition to or in the alternative to the aforementioned perforation ratio and score depth. For example, patterns in which controlled cuts are provided in the clear media are preferably adapted to facilitate desired destruction of the clear fungible postage indicia.

(30) Controlled cuts utilized according to embodiments of the invention may be disposed at particular locations and/or oriented on a clear fungible postage indicium to encourage or ensure destruction of the indicium if removal from a host object (e.g., postal item 201) is attempted. For example, a person attempting to remove an indicium from a host object tends to attempt to initially separate the indicium from the host object at the corners of the indicium medium. Thus, controlled cuts of embodiments of the invention may be disposed at or near the corners or other expected site of initial separation to cause separation of portions of the indicium medium as the person attempts to separate the indicium from the host object. Additionally, a person attempting to remove an indicium from a host object tends to peel the indicium from the host object after separating a small portion from the host object. Thus, controlled cuts of embodiments of the invention may be oriented with regard to one or more expected directions of peeling the indicium medium to cause separation of portions of the indicium medium as the person attempts to separate the indicium from the host object.

(31) Controlled cuts of embodiments of the invention not only provide for separation of portions of the medium for destruction of the indicium, but may additionally result in physical deformation, distortion, etc. (collectively, alteration) of the medium. For example, the portions of perforation line 310 remaining uncut may be adapted (e.g., sized and/or shaped) to provide sufficient structural integrity to cause stretching or other alteration of the medium as the portions of the medium are separated when an attempt to separate the indicium from the host object is made. Such alteration of the medium renders the separated portions of the clear fungible postage indicium more difficult, if not impossible, to subsequently piece together without readily apparent signs of tampering (e.g., stretched portions of the torn perforation line prevent the separated pieces from abutting one another to appear unified as before separation of the indicium from the host object.

(32) The portions of the indicium medium separated by controlled cuts of embodiments herein may be selected to further facilitate rendering the indicium unusable, to avoid interference with particular portions of the indicium, to facilitate printing of various indicia information, etc. Accordingly, various controlled cut patterns may be utilized according to embodiments of the invention.

(33) Directing attention to FIG. 5, a controlled cut pattern which results in separation of particular portions of the clear fungible postage indicia is shown. Specifically, controlled cuts 501a and 501b, which may comprise perforation lines, score lines, etc., are disposed to facilitate separation of human readable indicia information 101, machine readable indicia information 102, and markers 103a and 103b. Such a pattern of controlled cuts results in portions of the clear fungible postage indicia which are often critical to successful processing and/or validation being separated from one another when removed from a host object (e.g., postal item 201), thus likely resulting in the clear fungible postage indicia being prevented from successful reuse. Moreover, the controlled cuts of the embodiment of FIG. 5 are disposed to avoid interfering with the printing of information, such as the contents of human readable indicia information 101, machine readable indicia information 102, and markers 103a and 103b, such as by a printer of computer system 240 and/or of a supplier of sheet 200.

(34) Additionally or alternatively, a controlled cut pattern or patterns may be utilized which result in the breaking up of particular portions of the clear fungible postage indicia (e.g., breaking any of a human readable portion, a machine readable portion, and/or an marker portion into smaller pieces). Directing attention to FIG. 6, a controlled cut pattern which results not only in separation of portions of the clear fungible postage indicia, but also in breaking up of particular portions of the clear fungible postage indicia, is shown. Specifically, controlled cuts 601a, 601b, and 601c, which may comprise perforation lines, score lines, etc., are shown in the embodiment of FIG. 6. Controlled cut 601a is disposed to facilitate separation of markers 103a and 103b, controlled cut 601b is disposed to facilitate breaking up of machine readable indicia information 102 ad separation of markers 103a and 103b, and controlled cut 601c is disposed to facilitate breaking up of human readable indicia information 101, machine readable indicia information 102, and markers 103a and 103b. Such a pattern of controlled cuts results in portions of the clear fungible postage indicia which are often critical to successful processing and/or validation being broken up when removed from a host object (e.g., postal item 201), thus likely resulting in the clear fungible postage indicia being prevented from successful reuse.

(35) It should be appreciated that disposing controlled cuts through various information printed upon the indicium medium may result in some impact upon the quality of the printed information. For example, surface perturbations associated with the controlled cuts may result in small spaces where ink or other printing material is missing from the printed rendition of the information. Such impacts upon the quality of the printed information are expected to generally be acceptable for processing and validation of the clear fungible postage indicia. For example, machine readable indicia information 102 is likely to be the most susceptible to problems resulting from reduced printing quality. However, machine readable coding techniques, such as those of the PDF417, DATAMATRIX, MAXICODE, and other two-dimensional bar codes, provide error correction able to accommodate relatively poor print quality and other sources of damage to the barcode. Nevertheless, it may be desirable to provide a controlled cut pattern which does not pass through selected information printed upon the indicium.

(36) Directing attention to FIG. 7, an embodiment wherein a pattern of controlled cuts is used which provides for breaking up of some portions of the clear fungible postage indicia and separation, without breaking up, of other portions of the clear fungible postage indicia. Controlled cuts 701a through 701h, which may comprise perforation lines, score lines, etc., are shown in the embodiment of FIG. 7. Controlled cuts 701a and 701b are disposed to facilitate separation of human readable indicia information 101, machine readable indicia information 102, and markers 103a and 103b. Additionally, controlled cuts 701c through 701h are disposed to facilitate breaking up of human readable indicia information 101. As can be appreciated from the embodiment illustrated in FIG. 7, controlled cut patterns may avoid controlled cuts in certain areas, such as a machine readable portion to avoid interfering with the functionality of that portion of the clear fungible postage indicia, while providing controlled cuts within other areas, such as the human readable portion to facilitate breaking up of that portion of the clear fungible postage indicia.

(37) FIG. 8 shows an embodiment wherein a pattern of controlled cuts, shown as perforation cut lines 801a-8011, are provided to facilitate destruction and/or separation of various portions of the clear fungible postage indicium. For example, perforation cut lines 801a, 801b, 801e, and 801f facilitate separation of a particular portion of human readable indicia information 101 while perforation cut lines 801b, 801c, 801f, 801g, and 801i-8011 facilitate breaking up of another portion of human readable indicia information 101. Perforation cut lines 801c, 801d, 801e, 801f, and 801g of the illustrated embodiment facilitate breaking up of machine readable indicia information 102.

(38) FIG. 9 shows another embodiment wherein a pattern of controlled cuts, shown as perforation cut lines 901a-901j, are provided to facilitate destruction and/or separation of various portions of the clear fungible postage indicium. In the embodiment of FIG. 9, perforation lines 901-901d facilitate separation of a particular portion of human readable indicia information 101 while perforation cut lines 901b, 901e, 901i, and 901j facilitate breaking up of another portion of human readable indicia information 101. Perforation cut lines 901e-901h facilitate breaking up and separation of machine readable indicia information 102.

(39) It should be appreciated that the embodiments of FIGS. 8 and 9 illustrate the use of perforation cut line configurations of embodiments of the invention. In order to facilitate destruction of the various portions of the clear medium, the intersections of the perforation cut lines shown in the illustrated embodiments include joined perforations. That is, perforations of the different intersecting perforation cut lines are made to join to thereby provide a weakened intersection for facilitating separation and destruction of the various portions of the clear medium. Alternative embodiments of the invention may not use joined perforations at some or all such perforation line intersections, such as at particular locations susceptible to premature destruction of the clear medium (e.g., a location prone to substantial bending during removal from a carrier for placement upon a host object). Such embodiments may utilize a configuration wherein, although the perforations do not necessarily join at a perforation line intersection, the intersection is sufficiently weakened (e.g., through the use of a higher perforation ratio at the intersection than used at other portions of the perforation cut line) to facilitate destruction of a clear fungible postage indicium upon removal from a postal item. Such weakened perforation cut line intersections may be additionally or alternatively provided using score lines (e.g., the web of remaining clear medium between perforation cuts may itself be scored) according to embodiments.

(40) Although FIGS. 8 and 9 are discussed above with respect to perforation cut lines and the use of weakened perforation cut line intersections to facilitate destruction of a clear fungible postage indicium, score line embodiments of the invention may be similarly adapted. For example, the depth of the score lines may be increased at score line intersections to thereby weaken the intersections.

(41) Clear fungible postage indicia of embodiments may implement techniques in addition to or in the alternative to the foregoing controlled cuts for providing security. For example, embodiments of the invention may utilize a laminated or multi-layer clear medium configuration adapted to facilitate destruction of the clear fungible postage indicia produced therewith. According to embodiments of the invention, multiple layers (e.g., 2 or 3 layers) of very thin clear plastic media may be adhered together to provide a laminated clear medium (e.g., to provide a top layer upon which information of a clear fungible postage indicium is printed and a bottom layer upon which an adhesive is provided to adhere the clear fungible postage indicium to a host object, wherein the top layer and bottom layer are laminated together to provide a multi-layer medium). The adhesive or adhesives used in laminating the layers may be selected to provide sufficient integrity of the laminated clear medium to facilitate handling of clear fungible postage indicia, such as when being printed, removed from a carrier substrate, and placed upon a host object, but which results in delaminating or partial delaminating when an attempt is made to remove the clear fungible postage indicia from the host object. The adhesive or adhesives used in laminating the layers of the laminated clear medium may, for example, provide less adhesive force than that of the adhesive or adhesives used to affix the clear fungible postage indicia upon the host object. It should be appreciated that the foregoing laminated clear medium security techniques may be implemented in combination with the controlled cuts discussed above, such as to provide a clear medium which is highly likely to facilitate the destruction of a clear fungible postage indicium made therewith.

(42) Additionally or alternatively, techniques for providing security implemented according to embodiments of the invention may comprise features other than adaptation of the clear medium itself. For example, embodiments of the invention may utilize adhesive patterning to facilitate destruction or otherwise disabling the clear fungible postage indicia when removal from a host object is attempted. According to an embodiment, adhesive patterning may deposit adhesive in particular areas and leave other areas free of adhesive (e.g., areas near and/or underlying a controlled cut) to work cooperatively with a controlled cut to facilitate separation of portions of the clear medium when the fungible postage indicia is removed from a host object. For example, an adhesive pattern may be applied to the back of the clear medium of clear fungible postage indicium 100 in a pattern corresponding to that of the controlled cuts, leaving areas of no adhesive corresponding to one or more controlled cuts, in order to facilitate separation of the portions of the indicium medium at the controlled cuts.

(43) FIG. 10 shows an embodiment of adhesive patterning as comprising adhesive areas 1001a through 1001n applied to the back of clear medium 110 in correspondence to controlled cuts 701a through 701h shown in FIG. 7. In the embodiment of FIG. 10, adhesive areas 1001a through 1001n provide adhesive to the uncut portions of clear medium 110 while leaving areas without adhesive corresponding to controlled cuts 701a through 701h. Accordingly, the uncut portions of clear fungible postage indicium 100 will be encouraged to remain on a host object while the controlled cuts are free to separate from one another as the indicium is being removed from the host object. Thus, destruction of the clear fungible postage indicia when removal is attempted after affixing to a host object is facilitated through the use of such adhesive patterning.

(44) Embodiments of the invention may additionally or alternatively utilize adhesive adaption in the form of adhesion characteristic variation to facilitate destruction or otherwise disabling the clear fungible postage indicia when removal from a host object is attempted. Such adhesion characteristic variation may comprise the use of adhesives of different adhesion characteristics used at different portions of the clear medium (e.g., exterior edges, portions at or near controlled cuts, beneath particular aspects of the fungible postage indicia, etc.) for facilitating destruction of the clear fungible postage indicia.

(45) Adhesive adaption in the form of visible characteristics may additionally or alternatively be used to provide security with respect to clear fungible postage indicia. According to an embodiment, adhesive adaption in the form of adhesive colorization may be utilized to provide a pattern (e.g., image, logo, text, information, etc.) within the adhesive. For example, medium code 104, aesthetics 105, (FIG. 1) etc. may be provided through use of adhesive colorization to print the pattern within the adhesive on the back face of clear medium 110 (e.g., adhesive 211 shown in FIG. 2B). For example, clear medium 110 may have adhesive 211 applied to a back face thereof (e.g., before placing clear medium 110 upon carrier 210) during a manufacturing process. A portion of the adhesive may be colorized to provide a desired pattern (e.g., symbols, characters, graphic image, etc.) and/or a colorized agent or ink may be applied to a portion of the adhesive after its deposit upon the back face of the clear medium to provide a desired pattern. Such an adhesive colorization patterns are preferably visible through clear medium 110 of clear fungible postage indicia 100. Moreover, because the pattern (e.g., the alphanumeric characters of code 104) is provided in the adhesive layer used to attach clear fungible postage indicia 100 to a host object, such as postal item 201, the pattern is highly likely to be visibly altered or damaged if the clear fungible postage indicia is removed from a host object. For example, the pattern of adhesive colorization may be separated from the clear medium, partially separated from the clear medium, smudged or smeared, etc., thereby providing visual evidence of removal or attempted removal of clear fungible postage indicia 100 from a host object.

(46) Adhesive colorization and patterning may be provided in a number of ways according to embodiments of the invention. For example, a desired pattern (medium code 104, aesthetics 105, (FIG. 1) etc.) may be applied (e.g., sprayed, ink jet printed, silk screened, etc.) in ink or other colorizing agent to the back of an adhesive layer already present on a back face of the clear medium. Such an application of colorization to the adhesive may be particularly effective in providing visible separation of the pattern upon the attempted removal of the clear medium from a host object due to its being disposed on the surface interfacing with the host object. Adhesive colorization patterning may additionally or alternatively be applied through patterned application of colorized adhesive (e.g., similar to the techniques used in adhesive patterning resulting in the patterns shown in FIG. 10). For example, colorized adhesive may be printed in a desired pattern (medium code 104, aesthetics 105, (FIG. 1) etc.) and clear adhesive printed in the remaining areas to fully cover a portion of a back face of the clear medium. Such an application of colorization to the adhesive may be partially removed upon the attempted removal of the clear medium from a host object to thereby provide a visual indication of the attempted removal.

(47) It should be appreciated that one or more of the foregoing security features adapted to provide an indication of removal or attempted removal of a clear fungible postage indicium from a host object may not be the only security features implemented according to embodiments of the invention. Security features, such as the use of special inks, may be utilized to prevent the copying and reproduction of clear fungible postage indicia according to embodiments of the invention. For example, special inks which are invisible under natural light, but which fluoresce under light of a particular wavelength (e.g., ultraviolet light), may be applied to clear medium 110 (e.g., to form all or a part of include human readable information 101, machine readable information 102, markers 103a and 103b, medium code 104, and/or aesthetics 105) to render reproduction by typical copying techniques ineffective.

(48) The use of special inks which are invisible under natural light (e.g., inks which fluoresce under ultraviolet light) are particularly useful with respect to clear fungible postage indicia of embodiments due to their use not substantially impacting the aesthetics provided by the use of the clear fungible postage indicia. For example, markers 103a and/or 103b may be comprised entirely of such special inks for use in automated processing of postal items, facing of postal items for processing, postage indicium validation, etc., without significantly impacting or otherwise altering the appearance of clear fungible postage indicia 100.

(49) Special inks which visually appear to have different characteristics (e.g., change color), such as thermo-chromatic inks, may additionally or alternatively be applied to the clear fungible postage indicium medium to render reproduction by typical copying techniques ineffective. For example, aesthetics 105 may be provided to include a portion comprised of such special inks to facilitate validation of clear fungible postage indicia 100 through the use of special inks in an unobjectionable manner. Although such visible inks may not be preferred according some embodiments due to it impact upon the aesthetics provided by the use of the clear fungible postage indicia, there use in a subtle or otherwise aesthetically pleasing way may not be objectionable.
