Abstract
An array of a multiplicity of ten-by-ten grids of pixels per video frame is employed to form a watermark mask. Motion of a pixel block is determined by a pseudo-random sequence from a seed value. The resulting invention embeds data as binary bits by shifting one or more color space values of a small patch of pixels.
