Improved Color Plane Permutation for Satellite Imagery Encryption

Abstract

The standards Image coding permitted the wide-ranging spread use for applications of multimedia. Nowadays, digital documents might make discrete over the World Wide Web to a many number of customers in a cost efficient way. So the real need for more security and services to keep the provision of digital multimedia work both profitable for the document owner and reliable for the customer. Privacy and Authentication services for multimedia data streaming are crucial in today data dissemination through internet. This paper focuses on Image security and integrating encryption with multimedia (Satellite Imagery) compression method. However, Image encryption algorithms combining with JPEG encoding are proposed. the approach for integrating encryption with image compression system are proposed, Improved Color Plane Permutation. The proposed method is improved by selective encryption, were a portion of the coefficients from either the final results or intermediate steps of a compression method are enciphered with a cryptographic cipher. The securities of the proposed approach are analyzed Experimental results and compared with the results that obtained from traditional algorithm such as (Chaotic). The proposed system is more secure, of low cost, supports direct bit-rate control and is more robust to transmission errors. These properties make it suitable for multimedia applications with real – time operation and image transmission over a network.
