System for detecting reorigination of barcodes
View Patent ↗A system for detecting reproduction of barcodes ( 12 ) includes providing a barcode which contains data; providing a copy-evident background ( 14 ); capturing an image of the barcode and the copy-evident background; locating and decoding the barcode; detecting copy introduced changes in the copy-evident background; and authenticating the barcode if the copy-evident background has not been copied.
1. A system for detecting reorigination of barcodes comprising:
providing a multisegment barcode which contains data;
an image capture device for capturing an image of the multisegment barcode;
a microprocessor for locating the barcode in the image and decoding the barcode;
detecting individual segments in the multisegment barcode;
comparing lengths of the individual segments in the multisegment barcode to lengths of the segments of the original barcode; and
authenticating the barcode if the individual segment lengths of the multisegment barcode match the individual segment lengths of original barcode.
2. The system of claim 1 wherein the microprocessor is housed in the image capture device.
3. The system of claim 1 wherein the image capture device is selected from a group consisting of a cell phone, a digital camera, a barcode reader, a document scanner or a tablet.
4. The system of claim 1 wherein the barcode is a Quick Response (QR) code.
5. The system of claim 1 further comprising:
authenticating the barcode on site by means of a computer or other computational device.
6. The system of claim 1 further comprising:
a first transmitter for transmitting the data obtained from the barcode, an image of the barcode, or both to a remote location for authentication.
7. The system of claim 6 further comprising:
a second transmitter for transmitting a confirmation of authentication from the remote location to the site.
8. A system for detecting reorigination of barcodes comprising:
providing a barcode which contains information data and encoding parameters;
an image capture device for capturing an image of the information data and encoding parameters;
a microprocessor for locating the barcode in the image and decoding the barcode;
detecting at least one encoding parameter; and
authenticating the barcode if the at least one detected encoding parameters matches the original barcode.
9. The system of claim 8 wherein the microprocessor is housed in the image capture device.
10. The system of claim 8 wherein the image capture device is selected from a group consisting of a cell phone, a digital camera, a barcode reader, a document scanner or a tablet.
11. The system of claim 8 wherein the barcode is a Quick Response (QR) code.
12. The system of claim 11 wherein the encoding parameters are selected from a group consisting of an error correction level, a mask parameter or version.
13. The system of claim 8 further comprising:
authenticating the barcode on site by means of a computer or other computational device.
14. The system of claim 8 further comprising:
a first transmitter for transmitting the data obtained from the barcode, an image of the barcode, or both to a remote location for authentication.
15. The system of claim 14 further comprising:
a second transmitter for transmitting a confirmation of authentication from the remote location to the site.
