Applications of optoelectronic watermarking technique to new business and industry systems utilizing flat-panel displays and smart devices

Abstract

Proposed are new applications of image displays to invisible optoelectronic watermarking systems whose technique will be effective in business and industry. The system is basically characterized by paired installer and viewer of new kind to transfer hidden invisible auxiliary data on watermark code patterns. A flat-panel image display enabled us to demonstrate invisible data hidden behind the watermark codes embedded into object image data by use of the installer. Smart devices placed against the flat panel displays enabled us to establish an optical link between them in a variation of the system for taking out and reading the watermark codes by use of the viewer. So, each smart device could also be used to resume original auxiliary data on the small display attached to the viewer. This kind of optoelectronic system established with a smart device was experimentally confirmed to be applied to business and industry by transferring alphanumeric characters stably.
