Summary:The Color to Gray and Back transformation watermarking with a secrete key is considered. Color is embedded into the bit planes of the luminosity component of the YUV color space with the help of a block algorithm that allows using not only the least significant bits. An application of the problem of distributing color digital images from a data base among legitimate users is discussed. The proposed protocol can protect original images from unauthorized copying.
