Electronic tagging of blank canvas with unique identity to allow artists to safeguard against illicit copying of their work, uses transponder chip invisibly incorporated into canvas and carrying unique identification data

摘要

The blank canvas (1) is tagged (2) with a read-only electronic transponder chip operating at 125 kHz. The chip is integrated into the canvas so that it is invisible and leaves a flat painting surface. The transponder stores a unique identification which cannot be altered. The identification might be a code, an image or a description. The transponder is read with a portable or fixed reader.
