Review: Image Encryption Techniques based on Chaotic Map

Due to the tremendous developments in communication networks especially in the Internet network, which used to exchange many types of data by many people. Data security has become a major concern. Therefore, there is an increasing interest in the use of encryption and decryption methods. Many encryption methods have been developed to maintain data security, one of these methods that commonly used in recent are chaotic encryption systems. Where many methods were suggested to encrypt images using a chaotic map because their features such as sensitivity to initial conditions and unpredictability of random behaviors etc... In this paper, we attempt to review and describe many methods used to encrypt images and make a comparison among these methods
