Abstract

Claims (24)

1. A method for detecting reorigination of multisegment barcodes comprising:

providing a multisegment barcode having individual segments each comprising strings of characters each string having a length;

capturing an image of the multisegment barcode;

locating the multisegment barcode in the image;

decoding the multisegment barcode;

detecting individual segments in the multisegment barcode; and

authenticating the multisegment barcode if the characters and the length of the string of each of the individual segments match the characters and the length of the string of each segment of an original barcode.

2. The method of claim 1 wherein the image is captured by an image capture device.

3. The method of claim 2 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 method of claim 1 wherein the multisegment barcode is located in the image by a microprocessor.

5. The method of claim 4 wherein microprocessor and is housed in an image capture device.

6. The method of claim 1 wherein the multisegment barcode is a Quick Response (QR) code.

7. The method of claim 1 further comprising:

authenticating the multisegment barcode on site by means of a computer or other computational device.

8. The method of claim 1 further comprising:

transmitting the data obtained from the multisegment barcode, an image of the multisegment barcode, or both to a remote location for authentication.

9. The method of claim 8 further comprising:

transmitting a confirmation of authentication from the remote location to the authentication site.

10. A method for detecting reorigination of barcodes comprising:

capturing an image of a multisegment barcode, the multisegment barcode having individual segments each comprising strings of characters each string having a length;

locating the multisegment barcode in the image;

decoding the multisegment barcode;

detecting individual segments in the multisegment barcode; and

authenticating the barcode if the characters and the length of the string of each of the individual segments match the characters and the length of the string of each of an original barcode.
