Non Linear Chaotic Map for Secure Data Transmission

In today?s world, Internet plays a major role in people?s communication. People nowadays share and transfer variety of multimedia information through the Internet. Although a lot of benefit with it, data transfer over Internet is vulnerable to attack is a major hindrance. Cryptography is the science used to keep the information safe from attack. In the case of text data transfer more number of encryption techniques are existing whereas when it comes to image very less number of techniques are available. Also, the traditional image encryption methods are not viable enough for modern images due to their different storage formats. Hence research on image encryption becomes inevitable. In this paper, we have proposed Non linear chaotic map technique to encrypt the images and performance of the same has been evaluated. This study shows Non linear chaotic map has higher performance for images
