A Compressible Threshold Image Sharing Scheme Based on Matrix Projection

  • Based on matrix multiplication secret sharing theory,a new compressible image sharing scheme is proposed.Taking advantage of compressible matrix projection,this scheme directly creates shadow image so as to,consequently,effectively overcome the drawback which requires the secret image is permutated before it is shared in literature.Besides,its complex degree is lower than the scheme's one in literature.Meanwhile,this scheme reduces the size of each shadow image to become 1/t of the secret image's one.
