DETAILED DESCRIPTION OF THE INVENTION
(5)
(6) Postal service provider infrastructure 130 of embodiments provides a processor-based system (e.g., one or more server, computer, workstation, etc. and associated peripherals) adapted to process mail items for which postal services are to be provided. Accordingly, mail server 131 of postal service provider infrastructure 130 of embodiments is adapted to accept input of mail item information (e.g., addressee information, addressor information, routing information, postal services information, proof of payment for services information, etc.), such as through the use of scanner 133 (e.g., an optical scanner, a barcode scanner, a radio frequency identification (RFID) tag reader, etc.), to provide various mail item processing (e.g., mail piece sorting, postal services processing, parasitic postage indicia validation, etc.).
(7) Postage system 140 of embodiments provides a processor-based system (e.g., one or more network application server, computer, etc. and associated peripherals) adapted to generate parasitic postage indicia in accordance with information provided thereto. Accordingly, postage system 140 of embodiments is adapted to communicate with systems (e.g., postal service provider infrastructure 130 and/or mailer system 150), to generate and appropriately account for parasitic postage indicia (e.g., access one or more crypto vault storing value), and to cooperate with other systems utilized in providing parasitic postage indicia of embodiments.
(8) Mailer system 150 of embodiments provides a processor-based system (e.g., one or more computer, workstation, kiosk terminal, etc. and associated peripherals) adapted to cooperate with a postage system (e.g., postage system 140) to generate desired postage indicia and to print information of parasitic postage indicia herein for use on mail items. Accordingly, mailer system 150 of embodiments includes printer 152 (e.g., a laser printer, an ink jet printer, a label printer, etc.) for printing information of parasitic postage indicia, such as part of a mail scan block, directly on mail items (e.g., on mail item 120 as part of postal information block 110) and/or indirectly on mail items (e.g., on label stock 114).
(9) From the foregoing it can be appreciated that postal service provider infrastructure 130, postage system 140, and mailer system 150 of embodiments comprise processor-based systems operating under control of one or more instruction set (e.g., software, firmware, applet, etc.) to provide operation as described herein. Such processor-based systems may comprise a central processing unit (CPU) (e.g., a processor from the PENTIUM or CORE line of processors available from Intel Corporation), memory (e.g., random access memory (RAM), read only memory (ROM), flash memory, disk memory, optical memory, etc.) storing the aforementioned one or more instruction set and/or other data used herein, and appropriate input/output circuitry and devices (e.g., network interface card (NIC), keyboard, digital pointer, display screen, peripheral interface, microphone, speaker, wireless interface, etc.). Peripheral devices, such as one or more printer, scanner (e.g., optical scanner, barcode scanner, and/or biometric sample scanner), etc. may be included for use with any or all of the foregoing processor-based systems according to embodiments herein.
(10) It should be appreciated that although shown in the illustrated embodiment as separate systems, postal service provider infrastructure 130, postage system 140, and mailer system 150 may be provided in other configurations, whether combined or further distributed. A system configuration in which one or more of postal service provider infrastructure 130, postage system 140, and mailer system 150 are combined may be desired in some situations, such as where a postal service provider offers parasitic postage indicia generation and purchase at their public facilities.
(11) Network 101 of the illustrated embodiment provides communication links facilitating the communication between various systems and components of system 100, such as postal service provider infrastructure 130, postage system 140, and mailer system 150. Accordingly, network 101 may comprise any number of network configurations, such as the Internet, an intranet, the public switched telephone network (PSTN), a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a cellular network, a wireless network, a cable transmission network, and/or the like.
(12)
(13) Postage indicia data generated according to embodiments of the invention comprises data sufficient to satisfy requirements of a corresponding postal service provider for proof of payment for postal services. For example, embodiments of the invention may operate at block 203 to generate postage indicia data in conformance with IBI specifications promulgated by the USPS. Such postage indicia data may include information useful in providing the postal services, in discouraging fraud, in facilitating tracking and accounting, etc., such as a digital signature, the aforementioned postage meter account information, postage parameters, and/or mail item information, etc. Techniques for the generation of postage indicia data as shown and described in the aforementioned United States patent applications entitled “Image-Customization of Computer-Based Value-Bearing Items” and “System and Method for Printing Postage Indicia with Post-By Date” may be utilized according to embodiments of the invention.
(14) In order to associate the generated postage indicium data with a corresponding mail item for which it was generated, embodiments herein utilize thin indicium information of a parasitic postage indicium herein. Accordingly, thin indicium information is generated at block 203 of the illustrated embodiment. Such thin indicium information preferably provides substantially unique identification information (i.e., information which is not repeated in typical use, although it may be repeated at intervals sufficiently long to mitigate commonality among viable unique identification information, and thus may be relied upon as substantially unique information) for identification of associated postage indicium data.
(15) Postage indicia data generated according to embodiments of the invention is not printed as postage indicia for applying to mail items as is typically the case with IBI postage metering techniques. Instead, system 100 of embodiments herein operates to store generated postage indicia data as postage indicium data packets at block 204. For example, postage indicium data packets may be stored in database 142 of postage system 141 and/or provided to a postal service provider in vendor log 144 for later use in proof of payment for postal services.
(16) Thin indicium information is preferably stored in association with the aforementioned postage indicium data packets for accessing an appropriate postage indicium data packet using corresponding thin indicia information. For example, thin indicium information may be stored in database 142 of postage system 141 and/or provided to a postal service provider in vendor log 144 in association with (e.g., using indexing, relational database, and/or other associative techniques) corresponding postage indicium data packets as shown by records 143 at block 204 of the illustrated embodiment.
(17) Thin indicium information of embodiments of the invention comprises one or more pieces of information configured to be borne in parasitism within a structure of a mail scan block present on a mail item. For example, thin indicium information may comprise information adapted to be carried as one or more component of mail scan block 111, such as may comprise an IM barcode, present on mail items for a purpose or purposes other than providing postage indicium. The IM barcode of the foregoing exemplary embodiment may be provided for use in routing and providing services by the USPS and may be placed in proximity to the addressee information (shown here as being placed above the addressee information) on the face of mail items in the United States to facilitate its being scanned during mail processing.
(18) As previously mentioned, thin indicium information preferably uniquely or substantially uniquely identifies a postage indicia data packet comprised of postage indicia data. Accordingly, the one or more pieces of information of thin indicium information of embodiments is both configured to be carried within a structure of a mail scan block and to provide substantially unique identification of corresponding postage indicium data.
(19) Directing attention to
(20) Embodiments of the invention provide thin indicium information adapted for disposing in mailer identification 303 and sequence number 304 of IM barcode components 300 in parasitism. For example, one or more parasitic postage indicia service provider number unique to a service provider responsible for postage system 140, or otherwise associated with the generation and/or validation of the parasitic postage indicium, may be used in combination with postage indicium identification numbers to provide thin indicium information 310. It should be appreciated that such an embodiment of thin indicium information 310 is adapted to be carried within components of IM barcode components 300 and to substantially uniquely identify a postage indicium data packet generated by postage system 140. In particular, a parasitic postage indicia service provider number may be adapted to be carried within mailer identification 303 of thin indicium information 310 while a postage indicium identification number is adapted to be carried within sequence number 304 of thin indicium information 310 without alternation of IM barcode components 300. For example, special or reserved mailer identification numbers may be utilized according to embodiments of the invention which provide an indication that the mail scan block comprises parasitic postage indicium information. This information may indicate that the sequence number component contains postage indicium identification number and therefore to use these components of the mail scan block to obtain postage indicium data. Thus, the combination of these numbers may be used to substantially uniquely identify postage indicium data by identifying a service provider having generated the postage indicium data and providing a postage indicium identification number or other identifier of the particular postage indicium data generated by that service provider.
(21) Because postage indicium generally has a short useful life (e.g., on the order of weeks), the postage indicium identification number of parasitic postage indicia of embodiments may repeat after all unique numbers available within the space of sequence number 304 have been exhausted and still provide substantially unique identification of the postage indicium data. If, however, additional time (e.g., extended shelf life) is desired before repeating of thin indicium information, the service provider may be provided with a plurality of parasitic postage indicia service provider numbers to allow sequencing through those parasitic postage indicia service provider numbers as the unique postage indicium identification numbers are exhausted.
(22) In operation according to embodiments of the invention, the thin indicium information is disposed in a mail scan block in parasitism for use in identifying the corresponding postage indicium data. Accordingly, referring again to
(23) Mail scan block 111 including thin indicium information may be printed alone or in combination with other information. For example, where mail scan block 111 comprises an IM barcode such an IM barcode may be printed in combination with addressee information 113, such as within postal information block 110. Additionally or alternatively, because inclusion of thin indicium information in parasitism in mail scan block 111 according to embodiments does not alter the mail scan block as generally perceived by humans, and thus provides no readily visible indication regarding the use of parasitic postage indicium (i.e., the presence of thin indicium information), embodiments of the invention may print one or more postage indicium presence demarcation in combination with mail scan block 111. For example, postage indicium presence information 112, such as may comprise a mark, character, message (e.g., U.S. Postage Paid), postage amount (e.g., $0.44), etc., may be provided as a humanly readable indication that a parasitic postage indium is provided with respect to the mail item. As other examples of other information that may be printed in combination with mail scan block 111 including thin indicium information, addressor information (e.g., addressor information 122), postal service information (e.g., First Class Mail, Return Receipt Requested, Airmail, etc.), postal processing information (e.g., FIM 121), and/or the like.
(24) The aforementioned other information may be printed or otherwise provided separately from a mail scan block including thin indicium information according to embodiments of the invention. For example, rather than using envelope media having postal processing information preprinted thereon, such postal processing information may be printed (whether preprinted by a supplier or printed by the mailer) upon label stock separate from postal information block 110. In accordance with an embodiment of the invention, label stock bearing preprinted FIM barcodes are provided for use with mail scan blocks including thin indicium information. Such FIM barcodes are fungible and thus generic to the particular mail items, thus application of label stock bearing preprinted FIM barcodes to mail items bearing mail scan blocks including thin indicium information does not present pairing or matching issues as would label stock comprising addressee information and separate label stock comprising corresponding postage indicia information.
(25) It should be appreciated that mail scan block 111 utilized according to embodiments of the invention may be disposed at locations on or within a mail item other than that shown in the embodiment illustrated in
(26) Mail scan block 111 including thin indicium information therein for providing parasitic postage indium herein may be printed directly or indirectly on mail items. For example, label stock 114 may be utilized as a print medium in printer 152 to accept printing of postal information block 110 including mail scan block 111. Label stock 114 may thus be applied to an appropriate mail item (e.g., mail item 120) when preparing the mail item for postal services at block 206. Alternatively, printer 152 may print mail scan block 111 directly upon a mail item (e.g., on mail item 120) or some portion thereof (e.g., an envelope or box used to contain pieces of the mail item) at block 206. Such printing of the mail scan block may include the aforementioned printing of other information. For example, where an envelope or similar portion of the mail item is used as a print medium in printer 152, information such as FIM 121 and/or addressor information 122 may be printed in combination with mail scan block 111. Additionally or alternatively, print media upon which mail scan block 111 including thin indicium information herein may be provided with other information (e.g., postal processing information such as a FIM, postal services information, etc.) pre-printed thereon. For example, stock (e.g., label stock, envelope stock, etc.) may be specifically provided having information pre-provided thereon for use with parasitic postage indicia herein.
(27) Mail item 120 having mail scan block 111 including thin indicium information therein may be introduced into the mail stream to receive desired postal services. For example, mail item 120 may be deposited into a receptacle (e.g., mailbox 134) of postal service provider infrastructure 130. Thereafter, mail item 120 may be processed by the postal service provider for providing the desired postal services. For example, automated sorting and scanning (e.g., using scanner 133) of the mail item may be performed. Mail scan block 111 is preferably scanned, or the information therein including the thin indicium information otherwise accessed, during one or more steps of the postal service provider mail processing at block 207.
(28) Mail scan block 111 utilized to bear thin indicium information in parasitism according to embodiments of the invention comprises a scan block for which components of postal service provider infrastructure 130 are relatively widely adapted to scan and/or for which components of postal service provider infrastructure 130 are readily adapted to scan. For example, scanning equipment capable of extracting information from IM barcodes has already been relatively widely deployed in mail processing infrastructure of the USPS. Accordingly, as mail item 120 is processed or otherwise handled by postal service provider infrastructure 130 of embodiments, an IM barcode embodiment of mail scan block 111 thereon may be scanned (perhaps for purposes other than or in addition to proof of payment verification) and the thin indicia information extracted for identifying a corresponding postage indicia data packet for proof of payment for postal services.
(29) Mail server 131 of postal service provider infrastructure 130 of embodiments is adapted to accept input of mail item information, including the aforementioned thin indicium information, to provide various mail item processing functions. In operation according to embodiments, mail server 131 will utilize the thin indicium information to determine that proper payment has been made for the postal services desired with respect to mail item 120. For example, mail server 131 and/or postage server 141 may utilize the thin indicium information (e.g., using information of vender log 144, as may be stored in database 132 of mail server 131, and/or information of records 143, as may be stored in database 142 of postage server 141) to identify a corresponding postage indicium data packet comprised of postage indicium data at block 208. The postage indicium data may be processed to determine its validity as postage indicia (e.g., that appropriate postage value has been paid for the postal services provided with respect to mail item 120) at block 209. For example, where postage indicium data comprises data consistent with that of an IBI based postage indicium, the postage indicium data may be processed for validation using the same techniques used with respect to information scanned from an IBI based postage indicium borne on a mail item.
(30) Once the parasitic postage indicium is validated through use of the thin indicium data and corresponding postage indicium data, mail item 120 may be provided further, appropriate postal services (block 211), such as to provide marking of the mail item (e.g., cancellation, validation, and/or value marking of the thin indicium), delivery processing of the mail item, mail item tracking and reporting, etc., where the thin indicium data is successfully validated. Alternatively, mail item 120 may be refused further postal services (block 210), or otherwise provided with exception processing (e.g., postage due processing, postage value debiting, return processing, etc.), if the thin indicium data is not successfully validated.
(31) It should be appreciated that particular operations of flow 200 may be performed in a different order than illustrated in the embodiment of
(32) From the above it can be appreciated that parasitic postage indicia of embodiments herein provides proof of payment for postal services for use in providing postal services borne within a mail scan block of a mail item. Moreover, where mail scan block 111 utilized to bear thin indicium information comprises a scan block for which scanning equipment capable of extracting information from the mail scan blocks has already been relatively widely deployed and/or for which components of postal service provider infrastructure 130 are readily adapted to scan, higher incidents of scanning of the thin indicium information, and thus verification of the parasitic postage indicium, may be performed. Such higher incidents of scanning may facilitate discouraging fraud, improved accounting and auditing, etc.
(33) The relative simplicity of mail scan blocks (e.g., IM barcodes) utilized according to embodiments of the invention not only facilitate the wide spread deployment of postal service provider infrastructure able to scan the mail scan blocks and obtain parasitic postage information of embodiments herein, but also facilitates the use of other devices to provide such scanning. For example, an app may be provided for execution upon portable processor devices, such as smart phones (e.g., IPHONE and DROID devices), tablet devices (e.g., IPAD and DROID tablets), and personal digital assistants (e.g., BLACKBERRY devices), facilitating capture of thin postage indicium data using a camera or other imaging apparatus of such portable processor devices. In such embodiments, a postal carrier, for example, may scan mail items at a point of pickup to determine the inclusion and/or validity of parasitic postage indicia.
(34) It should be appreciated that parasitic postage indicia provided according to embodiments of the present invention may be utilized to provide functionality in addition to or in the alternative to the aforementioned proof of payment for postal services. For example, where mail scan block 111 utilized to bear thin indicium information comprises a scan block for which scanning equipment capable of extracting information from the mail scan blocks has already been relatively widely deployed, scanning of the thin indicium information may be performed at a plurality of locations (e.g., at each postal service provider facility handing the mail item). Using the correspondence between the thin indicium information and the postage indicium data the mailer of the mail item may be identified (e.g., using information in the postage indicium data, information regarding an account used to generate the postage indicium data, etc.). This information may be utilized to provide the mailer with some level of mail item tracking information according to embodiments of the invention.
(35) Moreover, the inclusion of parasitic postage information within a mail scan block, particularly one which is otherwise present upon contents of a mail item, may facilitate the use of parasitic postage indicia herein. For example, various automated applications (e.g., accounts receivable, invoicing, accounts payable, check printing, and other software) may operate to print addressee and/or other information which may already include a mail scan block or otherwise be readily and unobjectionably adapted to include a mail scan block. Such applications may be adapted to include parasitic postage information of embodiments herein to thereby provide parasitic postage indicia where traditional postage indicia (e.g., IBI based postage indicia) is unacceptable (e.g., due to size, appearance, etc.).
(36) Although embodiments have been described herein with reference to printing mail scan blocks including parasitic postage indicia information (e.g., thin indicia information) therein, it should be appreciated that the concepts of the present invention are not limited to printed embodiments of mail scan blocks. For example, embodiments may utilize RFID tags provided as mail scan blocks upon mail items to carry parasitic postage information herein.
(37) Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims. Moreover, the scope of the present application is not intended to be limited to the particular embodiments of the process, machine, manufacture, composition of matter, means, methods and steps described in the specification. As one of ordinary skill in the art will readily appreciate from the disclosure of the present invention, processes, machines, manufacture, compositions of matter, means, methods, or steps, presently existing or later to be developed that perform substantially the same function or achieve substantially the same result as the corresponding embodiments described herein may be utilized according to the present invention. Accordingly, the appended claims are intended to include within their scope such processes, machines, manufacture, compositions of matter, means, methods, or steps.
