Full Spectrum Color Holographic Quick Response Code

Abstract

Information is recorded in quick response codes. A hologram is made from quick response codes and provides three dimensions of information in a two-dimensional hologram. The holograms are used for recording large amounts of information in two dimensions. Multiple quick response codes containing copious information are created using different light wave frequencies in different quick response encoders. The multiple quick response codes are combined in a two-dimensional hologram that is used on labeling. The hologram is read by a hologram reader. Each quick response frequency layer is separated from the hologram. The quick response code is extracted from each layer. A quick response reader provides the information that has been recorded.

DETAILED DESCRIPTION

[0043] FIG. 1 shows Examples of QR codes with Holograms which differ from Color Holographic QR codes.

[0044] The invention provides many new products 10, e.g. a custom manufacture hologram QR code 12, a custom made hologram QR code 14 and custom QR code 30 security hologram stickers 16.

[0045] The invention also provides custom hologram QR code tamper evident stickers 18 bar code and QR and hologram tags 22, and custom QR code and 3D security hologram stickers 24 with high security backings.

[0046] Also provided by the invention are QR coded holograms and hologram labels for passes 26, QR code tamper evident hologram stickers for high security 28, hot sale gold custom QR code 3D security hologram stickers 32, multiple QR code hologram labels for products such as galvanized iron pipes 34 and hologram identified containers 36.

[0047] To illustrate the new approach, a QR code is arbitrarily created, which could be as simple as a black and white (B/W) array of squares, or alternatively as sophisticated as a layer of three QR codes, in red, green and blue (RGB). The left side of FIG. 2 shows an example of a 48483-layer deep QR code 40 with both B/W and RGB components. Each of the 3-layers potentially could have information. The superposed information is decomposed using an imaging system with a dispersive hologram or is read directly with an imaging sensor and holographic decoding software. The right side of FIG. 2 shows that the holographic system cleanly separates 50 the 3-layers of information. Here each label consists of a 2D array of red, green and blue layer squares 52, 54, 56 such as shown in FIG. 3. This is a composite of narrowband R, G and B bit planes. Each plane is 8-bit, with square values 0 (dark) or 255 (light). That is, each pixel has the value (R.sub.ij, G.sub.ij, B.sub.ij) where each coordinate is either 0 or 255 or any range in between. Recovery of each layer of information is directly performed using an imager with a dispersive holographic optical element or read directly using holographic decoding software by which each R, G, B layer is read cleanly. Each layer is recovered completely as shown in FIG. 3.

[0048] Another alternate holographic system to use is image plane holography as illustrated in FIG. 4. The encoded QR bit array 72 in FIG. 4a is converted into a label using an image plane hologram 74 in FIG. 4b. To read the QR code's contents a device which could be an inexpensive molded diffractive type flat lens or added to a standard QR reader scans the label and recovers the input information 72 in FIG. 3c. Although this example uses a single layer of information, multilayer image plane holography is possible. Lenticular type holograms could also be used by which an image changes with the viewing angle.

[0049] FIG. 2 (Left) shows a 4848 3-layer QR code 40 superimposing three layers of information which could be extended to 24 layers or any number of layers of information. FIG. 2 (Right) shows an image 50 of the 3-layer QR code obtained with an imaging system using a dispersive hologram; all three layers are separated cleanly.

[0050] FIG. 3 shows recovered R, G and B layers 52, 54, 56 from the QR code in FIG. 2b, which could be extended to any number of color layers using variable color index to represent each bit layer of information.

[0051] FIG. 4 (a) shows a B/W QR code 72. FIG. 4b shows a label consisting of an image plane hologram 74. FIG. 4c shows the label reconstructed 76 with a reading device designed to read the hologram.

[0052] A key point uses the mathematics of holography to encrypt a code that cannot be copied. The bit-pattern for each layer is developed using a codebook 80 as shown in FIG. 5. A character is coded as a sequence of six bits. In one coding scheme six b/w squares are in each layer. Such a codebook can be adapted for different applications or products; it is possible to develop codebooks and encoding schemes that make it harder to counterfeit and/or enable anti-tampering capabilities. FIG. 5 shows a typical, readily tailorable to requirements, alphanumeric codebook.

[0053] The character table in FIG. 5 codes a series of cells in each layer as illustrated in FIG. 6.

[0054] FIG. 6 shows two examples 90 of bit-coding of words from the table in FIG. 5. FIG. 6 shows bit coding for the labeling two species of fish found in Hawaii. The bits can be arranged to form information stored in single layer B/W or colored QR codes.

[0055] The Po'opa'a Ulua Kihikihi 92 is bit-coded 94. The Humuhumunukunukuapua'a 96 is bit-coded 98.

[0056] The principle behind the new FSCHQR is a multicolored (i.e. multilayered) QR, or other data encrypted label format, code enables an efficient way to encode an enormous amount of data about the product as well as other supplier information over wavelength ranges ranging from UV through IR. Each supplier inserts various pieces of information in each QR code layer, or other data bit-coding format that is not specific to the well-known QR format, with the option of spreading crucial information over a number of separate layers to make this system more tamper-resistant. Such information includes product information, date of manufacture etc. Standard one, and two, dimensional barcodes can also be hidden inside the multilayer code. Furthermore, digital watermarking capability can be added if desired. The general form of the FSCHQR can take the form of a picture consisting of a two-dimensional array of black and white or color pixels arranged in such a way as to appear as a recognizable image, scene, or product logo, however with an embedded and hidden label. A good design of a FSCHQR code enables a measure of digital intricacy analogous to the intricacy of the engraved designs of paper currency. An illustration for the encoding of information with FSCHQR is shown in FIG. 7.

[0057] FIG. 7 shows FSCHQR 100 is able to encode an enormous amount of information and features. Supplier Information 102 includes, for example, manufacturer, past serial number, manufacture date, manufacturing location, item expiration date, security code, water mark and other information. An existing coding device 104 produces QR codes in red, green and blue 106. Those three QR codes are combined in a Color Holographic Quick Response hologram 110.

[0058] FIG. 8 shows decoding with FSCHQR proves the multi-layered defensive capability against tampering. The overall process for decoding with FSCHQR is illustrated in FIG. 8. FSCHQR readers have the form factor of several millimeters on a side and can be implemented using a scanner, camera, or smart phone camera device in combination with holographic decoding software algorithm applications. In software, all the QR or generalized bit-data layers, and any hidden barcode(s) therein, can also be extracted separately for decoding by existing QR and barcode readers extending the data retrieval capability of barcode readers significantly, by a factor of 3, 6, 12, 24 or more depending on the number of layers used. In general, this can be extended for any wavelengths other than RGB. For example, readers for FSCHQR can use one or more dispersive holographic elements or use imaging sensors with extended sensitivity in the infrared. Each dispersive element is a computer-generated hologram (CGH) that operates at a given waveband. That is, one CGH disperser can be used for UV, another for visible, and another for IR etc. and generates images similar to FIG. 7.

[0059] In FIG. 8 the CHQR hologram 110 is scanned 122 and read in a CHQR hologram reader 120. A processor 124 using a dispersive hologram cleanly separates 150 all layers 152, 154, 156 of the QR codes and extracts QR codes for each layer. An existing QR reader 170 retrieves all product information 172.

[0060] Another embodiment of this invention is to increase the number of layers from 3 (RGB) to 32, 64 or more; these extensions will greatly enhance anti-tamper capability. Algorithms now being developed at HNu via internal IR&D enable this phenomenal anti-counterfeiting and anti-tampering capability. The FWCHQR label adds layer information within each color through bit-planes.

[0061] Another embodiment of the FSCHQR label is that it can also be written to and displayed as an active label on any compatible device, computer monitor, smartphone, or any handheld device, or any active of interactive display screen. The result is a powerful re-writable FWCHQR label where product data can be added to the label at each point of processing along a supply chain, creating a complete ledger of the history of a product from raw material to a finished delivered product.

[0062] For each R, G, or B layer (or additional layers) instead of a standard single color B/W QR code, the invention has a more continuous encoded data image spanning all color bit planes that can be extended to any region of the spectrum ranging from the ultraviolet, to the visible as well as the infrared and that can be embedded in a recognizable picture, graphic, logo or other promotional material, thereby changing the look of labels to be marketing labels.

[0063] In FSCHQR existing or novel digital watermarking or steganographic algorithms can be incorporated within different layers, without affecting the data being stored.

[0064] The FSCHQR introduces new art to the CHQR color holographic coded label where the FSCHQR label can be used as a full spectrum data storage device which can be encoded and decoded (read and written) with holographic software algorithms without requiring holographic optical elements for secure personal information storage such as but not limited to; [0065] Personal Medical records [0066] Bank and credit card records, including a security code and data block imprinted on credit cards or currency [0067] Travel records such as driver licenses, passport, itinerary, etc. [0068] Purchasing Records, Recording Point of Sale Transactions. [0069] Inventory and supply chain management systems with traceability [0070] Complete ledger record of product from raw material to finished product [0071] Personal security data block [0072] Financial transaction record [0073] Currency authentication
