Abstract

As the growth in the technology increases maintaining the security of visual information during its transaction has to be increased. Rapid growth in the techniques for doing so is also increasing. Internet has become most commonly used media for communication and hence text, voice, video, Images and many more are transmitted through Internet. These might include Military Secrets, Commercial Secrets and Information of individuals and therefore it has to be transmitted by safer means with enhanced security. In the process of Visual Cryptography a secret image is encrypted into shares which refuse to divulge information about the original secret image. In this paper, Chaotic Pseudo – Random Number generation, Zigzag Scan Pattern Method, Method to reduce the degradation of the resultant image is proposed by an extension from gray to colour image. Pixel Index Method is discussed to improve the security for images. An integration of this technique of Visual Cryptography with (n, k, p) gray image is also proposed.
