摘要：Cryptography is the technique which is utilized for secure communication over the network. By using Cryptography technique readable information is converted into an unreadable form. Cryptography is used to protect data from unauthorized access. Universality of security in modern internet based application is an explicit motivation to contribute in the area of Information Security. Multimedia data contain different types of data that include text, audio, video, graphic, images. This paper gives an initiation of an amending technique for multiple selective region image cryptography based on both RC4 stream cipher and chaos. This approach is derived from the standard RC4 algorithm. But Currently RC4 is vulnerable. So for making image encryption technique more secure, we have proposed RC4 with chaos. We have shown that, our proposed method will boost image security over any type of network with several types of attack.
