Proposed are new applications of image displays to invisible optoelectronic watermarking systems whose technique will be effectively used 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. Smartphones placed against the flat-panel displays enabled us to establish an optical link between them in a variation of the prototype for taking out of the watermark codes by use of the viewer. Therefore, each smartphone could be also used to resume original auxiliary data on the small display attached to the viewer. This kind of optoelectronic system was established with the aid of a smartphone. It was experimentally confirmed to be applied to business and industry by transferring alphanumeric characters stably.
