Enhanced Security Scheme with Visual Cryptography and Steganography
Abstract
In this paper we present enhanced multi level secret data
hiding which integrates two different methods of encryption namely
visual cryptography and steganography. First as a pre-processing
step we are using a method called halftoning which is used to
reduce the pixels and simplify the processing. After that visual
cryptography is performed that produces the shares which forms
first level of security and then steganography in which we hide the
shares in different media like image, audio and video. Hence we get
the enhanced multi level secret data hiding which improves the
security over the network.
