Abstract: Recently, there is a need to concentrate more on protecting the information that is stored in computers from attackers due to the rapid growth of internet users. In this scenario, the issues of privacy, integrity, productivity, confidentiality and authenticity of images have become a significant issue for storage and communication of images. The encryption method is the best way towards maintaining the safety of transmitted data by transforming the information into an inconceivable form. Many image-based encryption methods have been proposed by various researchers in the past for protecting the information or data by providing the security from unauthorised users. This study discusses, analyses and identifies the issues from the previous encryption methods. This paper discusses the various encryption methods and reviews related works for each scheme. Finally, this study discusses the purpose of this image encryption technique in the future.
