Method for identifying and authenticating goods using codes, barcodes and radio frequency identification
Methods are described for identifying and authenticating goods. A code or checksum based on information or an image relating to a good is derived and associated with a barcode to include on a label. The label is scanned by a recipient to authenticate the goods. Scanable codes are provided based on an image by distilling an image into its hue components and using a grid to create a pattern. The pattern is readable by a scanner to obtain a code directly, or by consulting a look-up table. The code, barcode, digital barcode or scanable code can be included on a label or tag, such as an RFID tag.
1. A method of facilitating the authentication of items, comprising:
obtaining a code based on an image; and
associating the image and a machine-readable symbol comprising the code with one or more items to be authenticated, wherein the machine-readable symbol comprises data associated with at least one of the group consisting of shipping information, inventory information, invoice information, product type information, purchase order information, and signature information.
2. The method according to claim 1 , wherein the machine-readable symbol is a bar code.
3. The method according to claim 1 , wherein the image is a photograph.
4. The method according to claim 1 , wherein the image comprises textual information.
5. The method according to claim 1 , wherein the machine-readable symbol comprises a Reduced Space Symbology (RSS) bar code.
6. A method of authenticating items, comprising:
obtaining a first code based on an image associated with one or more items;
obtaining a second code based on a machine-readable symbol associated with the one or more items, wherein the machine-readable symbol comprises data associated with at least one of the group consisting of shipping information, inventory information, invoice information, product type information, purchase order information, and signature information; and
determining the authenticity of the one or more items based on the first and second codes.
7. The method according to claim 6 , wherein determining the authenticity of the one or more items comprises determining whether the first code matches the second code.
8. A symbol for facilitating the authentication of one or more items, the symbol comprising:
an image associated with the one or more items; and
a machine-readable symbol associated with the one or more items, wherein the machine-readable symbol comprises a code that is based on the image, and wherein the machine-readable symbol comprises data associated with at least one of the group consisting of shipping information, inventory information, invoice information, product type information, purchase order information, and signature information.
9. The symbol according to claim 8 , wherein the image comprises a first and a second guard bar for reading the first code associated with the image.
10. The symbol according to claim 8 wherein the image comprises a photograph.
11. The symbol according to claim 8 , wherein the image comprises a portrait.
12. The symbol according to claim 8 , wherein the image comprises textual information.
13. The symbol according to claim 8 , wherein the machine-readable symbol comprises a Reduced Space Symbology (RSS) bar code.
14. The symbol according to claim 8 , further comprising a label including the machine-readable symbol and image formed thereon for application to the one or more items.
15. A method of facilitating the authentication of items, comprising:
obtaining a code based on an image that comprises a plurality of regions, wherein the code is related to at least one of the plurality of regions; and
associating the image and a machine-readable symbol comprising the code with one or more items to be authenticated, wherein the machine-readable symbol comprises data associated with at least one of the group consisting of shipping information, inventory information, invoice information, product type information, purchase order information, and signature information.
16. The method according to claim 15 , wherein the code comprises a checksum.
17. The method according to claim 15 , wherein the code comprises encoding one or more pixels associated with the plurality of regions.
18. A method of authenticating items, comprising:
obtaining a first code based on an image associated with one or more items, wherein the image comprises a plurality of regions and the first code is related to at least one of the plurality of regions;
obtaining a second code based on a machine-readable symbol associated with the one or more items, wherein the machine-readable symbol comprises data associated with at least one of the group consisting of shipping information, inventory information, invoice information, product type information, purchase order information, and signature information; and
determining the authenticity of the one or more items based on the first and second codes.
19. The method according to claim 18 , wherein determining the authenticity of the one or more items comprises determining whether the first code matches the second code.
