摘要: A low-complexity grayscale image embedding scheme that can embed multiple secret images is proposed in this paper. In scheme, different users extract according to the keys they hold. To reduce storage cost of images, each first compressed using an improved version moment preserving block truncation coding scheme. The message then encrypted by DES cryptography system with key and embedded into host modulus least-significant-bit substitution technique. According experimental results, it shown consumes a little computational cost. Besides, number images. other words, indeed provides good approach for hiding access control.
