Visual cryptography is an advance encryption technique, which stores secret data within an image and splits this image into a number of slices. Each authorized user receives a single slice containing a portion of the cipher text. The message cannot be deciphered without superimposing all the slices in the proper order. Many existing papers concentrate on the processes during and after image-slicing. Although considered to be effective, these individual concepts are a major reason for compromising the security and privacy of a cryptosystem.
