"Randomized Visual Cryptography scheme for color images”
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 3
Abstract
Abstract: In this paper, we propose a new color visual cryptography scheme which is based on modified visualcryptography. Visual Cryptography is based on cryptography where n images are encoded in a way that onlythe human visual system can decrypt the hidden message without any cryptographic computations when allshares are stacked together. In this scheme sender can share n-1 natural images and one secrete image ofvariable size with the server and it make the encryption with extraction of feature of natural images withoutaltering the contents of natural images. When the receiver identification is done that time server make thedecryption process and send the secrete image with transmitted by highly secure secret channel. Moreover, thisapproach avoids the pixel expansion problem and makes it possible to recover secret images without anydistortion.
