Urvashi Yadav, Nisheeth Saxena . A Secure Visual Cryptographic Scheme based on Two Level Sharing. International Journal of Computer Applications. 106, 4 ( November 2014), 24-29. DOI=10.5120/18509-9581
Abstract
Visual cryptography allows the information to be encrypted using an encoding system. It does not require a computer to decode. Two transparent images are used in Visual Cryptography. One image contains the secret information and the other image contains random pixels. It is impossible to reveal the secret information from one of the images as both transparent images are required to retrieve the information. In this paper, we are working on the security of visual cryptography. Here we purpose a new scheme called three level sharing. In this case, we enhance the security of an image by dividing into shares and then after sub shares. For this purpose, stamping algorithm is used.
