Visual Cryptography for Color Image using Color Error Diffusion
ABSTRACT
Information security has become tremendously important because this is the world ruled by the technology. cryptography is the study of ways to convert information from its normal comprehensible form into an obscured guire,unreadable without special knowledge-the practice of encryption. visual cryptography is a new technique which provides information security which uses simple algorithm .unlike the complex ,computationally intensive algorithm used in other techniques like traditional visual cryptography .This techniques allows the visual information (pic,text) to be encrypted in such a way that their decryption can be performed without any complex cryptographic algorithms.
