NEW ALGORITHMS IN COLOR VISUAL CRYPTOGRAPHY

Abstract

Visual cryptography framework is a cryptographic technique which permits visual data (E.g. composed content, manually written notes and pictures) to be encoded in such a way, that decoding can be performed by the person visual framework, without the help of PCs.

There are different measures, on which execution of visual cryptography plot depends, for example,

• pixel extension, • contrast • security • Accuracy • computational unpredictability • share created is significant or negligible • nature of secret pictures( whichever double or shading) and • Number of secret images (whichever single or various) scrambled by the strategy.

Visual cryptography is a decent method for scrambling and unscrambling information on machines that have less figuring power since it doesn't depends on complex scientific squares and structures for encryption and decoding.
