Fast and lossless Image compression in chaos-based Encryption

Abstract

The wide use of digital images leads to the necessity of securing them when they enter into an insecure channel. Image cryptography plays a vital role in the modern communication. For telecommunication systems through the internet, various compression and encryption techniques are proposed to satisfy a fast and secure transmission. However these two techniques have been studied separately. In this paper we propose new approach of fast image encryption algorithm with chaos-based encryption system using by cipher structure and in compression process by using a context matching method driven by the correlation between adjacent neighbor mask pixels. With this approach the size of transmission can be reduce and transmission can be secure.
