Visual cryptography is a special type of encryption technique which is used to hide the information and data in images. In this paper, the decryption process is done without any complex cryptographic computation. The encrypted data is decrypted using Human Visual System (HVS). This is the advantage of the visual secret sharing scheme. The encryption technique requires a cryptographic computation to divide the image into a number of parts called share. This paper presents design of two stage binary image security scheme using (2 and 2) visual cryptography technique such that no one is able to get back the original image at the first decoding stage.
