Abstract

In the advent of booming communication technology, the needs for information sharing and transfer have increased exponentially which requires more and more new techniques to meet the increasing needs of a modern society. Visual cryptography scheme is a cryptographic technique which allows visual information (e.g. printed text, handwritten notes, and picture) to be encrypted in such a way that the decryption can be performed by the human visual system, without the aid of computers. Random grid based technique is a non expanded visual cryptographic technique for generating both meaningless and noise like shares. In this paper the idea is to increase the levels of security and to enhance the transmission speed of secret information over the network, as the basic model of Visual Cryptography is not an efficient tool to hide the information. In the proposed scheme initially the image is encrypted by Visual Cryptography using Random Grids and we propose a technique using combined DCT based Compression with Steganography for the speed transmission and additional security of encrypted random image shares over the transmitting media. The experimental results demonstrate the feasibility of the proposed scheme.
