Design and Implementation of Visual Cryptography System for Transmission of Secure Data

Abstract

In recent period of time security of the transmitted data is most critical problem, as network technology is greatly advanced and heaps of information is transmitted via net. Visual cryptography strategy is one of the most secure technique for privacy auspices, that allow the encryption of secret image or data by transferring it into the secure percentage and such a strategy is able to recover the secret image or data. This behavior makes visual cryptography especially useful for the low computation load requirement. In this paper, we are providing the information regarding information security by using Visual Cryptography scheme by making use of exclusive new technique of splitting of images along with their pixels rotation with the help of generated random number. We also have made an attempt to overcome some of the disadvantages of preexisting techniques of encryption and decryption. Finally, successful transmission of the message from transmitting end to receiving end without any interception was done. Most importantly, it is very difficult to hack by use of any professional hacking techniques as the message is encrypted twice. Hence the data is highly secured under transmission path
