lmage Sharing is an important measure to protect the image. By analyzing the quadratic residue theorem and Rabin Cryptosystem, and then an image sharing improve algorithm is presented based on this theory. The algorithm is lossless image sharing scheme. Experimental result indicates that the improve algorithm is with high security and good image recovering performance. Experiments have testified that this algorithm is effective. Some problems which may emerge from image sharing are discussed and the solutions are offered.
