Image Edge Barcode
A method is herein disclosed to add identification as a one-pixel line on the edge of an image which includes a barcode.
On capture applications using both scanners and mobile devices, it is common to place a watermark, sometimes in the form of a bar code, on a digital image that can later be used in classification, extraction, and storage to identify an image and associate it with a process or document type. In many applications, the identifying mark or barcode can obscure some part of the image.
For example, a normal image is attached to an insurance claim with specific metadata (e.g., claim number, data, etc.). If it becomes detached from that metadata, then it might not be possible to reattach it to the original claim. One way around this is for the camera (or scanner) to place a barcode somewhere on the document but the barcode might obscure some of the image or document information.
The disclosed method adds identification as a one-pixel line on the edge of an image
which includes a barcode. For the naked eye, this mark is nearly invisible, but can be visible when necessary. To see the barcode, a user only needs to zoom in on the image edge. Barcode scanning software scans the edges of the image for the barcode, instead of scanning the entire document. This increases the accuracy of finding the barcode on a digital image.
Some existing image watermarking systems invisibly encode the watermark into the image data (typically color/hue) to remain hidden; however, these require larger compute cycles to extract the information. These types of watermarks are made to remain secre...
