Region incrementing visual cryptography

Region incrementing visual cryptography is used to hide multiple secrecy levels in a single image. In proposed scheme, user does not need to address the area of different levels manually and levels are created automatically. User needs to use particular level information with a particular size of text. The traditional region incrementing visual cryptography scheme has been modified to address the problem of pixel expansion and poor contrast. In proposed algorithm, problem of pixel expansion and poor contrast has been removed and further it is modified to generate the levels automatically which is named as automatic region incrementing visual cryptography.
