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.
