DIFFERENT IMAGE ENCRYPTION METHODS: A SURVEY AND OVERVIEW

Abstract

The rapid development of digital communication and multimedia applications increases the need for protection and becomes an important problem for multimedia communication and storage. One of the methods used to guarantee high security is Image Encryption. Several areas, such as military medical research, in which picture encryption can be used. Modern cryptography offers important methods for information security and multimedia data safety. In recent years, encryption technology has been rapidly developed and many methods of image encryption have been used to protect confidential image data from unauthorized access. In this paper survey, researchers have discussed various image encryption techniques from which they can get an idea of using effective techniques.
