Abstract

Today general problem of society is undoubtedly security of digital image. Security of image in different stages like transferred, processed and stored thought digital channels (Guided or unguided media). In this era image cryptosystem has become an attractive and interesting field for research. Image cryptography improved the security of image from unauthorized sources. There are many algorithms and methods for making transmission secure and more reliable. Image watermarking is one of the favorite methods for encrypt order cryptan image.Chaos theory, due to its randomness and unpredictable behavior is more suitable for encryption, its characteristic is quite helpful in different encryption techniques and for multimedia security. Both image watermarking and chaos theory have its own methods, pros and cons. cryptography which are based on Chaos like Chebyshev polynomials can increase security when used with traditional public key cryptography like RSA and El-gamal, despite the fact that these methods are not standardized like AES, DES, RSA, etc. While chaos-based encryption methods are generally recommended by researchers due to their high computational efficiency, encryption algorithms like AES have historically been the preferred option when it comes to images or videos. In order to facilitate comprehension, this article surveys the most recent spatiotemporal, temporal, and spatial-temporal chaos-based image encryption methods. There is a discussion of the major advancements in image encryption. Additionally, comparative analysis is carried out to verify the evaluation matrices used in recent articles to quantify the security and efficiency of encryption algorithms.
