Analysis & Design of Visual Cryptography Using Moving Image

摘要

Cryptography, Steganography, Watermarking and many other techniques have evolved over a period of time, at the same time attacks on them have also increased as the data is in nuclear form (even though encoded), in these techniques. In last decade Visual Cryptography has evolved as an entity which divides the data into different shares and then embedding is done. This technique increases the overhead of multiple security and multiple output cover objects. In this paper we true to reduce this over head up to some extent by using GIF as cover image and reduce communication overhead.
