Visual cryptography is considered as a special encryption system that can be decrypted by human vision in a way without any type of computing process. This technique was proposed by Noar and Shamir in 1994.It also increases safety for our information in today`s increasingly open network environment. Visual cryptography uses two transparent images and both of them reveal the information. One image contains random pixels and the other image contains the secret information. This research adopts the concepts of basic idea of visual cryptography and introduces a method that increases the complexity of decryption by wrapping up one layer of images so that one can not perceive the secret information from one single share images.參考文獻 [1] Naor, M. and Shamir A.
