Abstract |
|
Cryptography is a process of storing and transmitting data in a form that is intended for read and process. It is a technique of protecting information by encrypting it into an unreadable form. In this paper, we consider a new type of cryptography technique which can decode a concealed images without any cryptographic computation. This scheme is perfectly secure and very easy to implement. Visual cryptography is an emerging cryptography technology that uses the characteristics of human vision to decrypt the encrypted images. It does not need cryptography knowledge and complex computation. From security point of view it also ensures that hackers cannot perceive any clues about a secret image from individual cover images. |
