Abstract

Security is an important issue in digital data transmission and storage. The security can be provided by image encryption. Encryption is one of the ways to provide high security when images are transmitted over the network. Image encryption techniques scrambled the pixels of the image and decrease the correlation among the pixels, so that we will get lower correlation among the pixel and get the encrypted image which is hard to understand. There are so many different image encryption techniques available to protect confidential image data from unauthorized access. Image encryption techniques which provide transmission of digital images in more secure way. Encryptions algorithms that are good for textual data may not be suitable for multimedia data because images contain large data. This paper present survey of various encryption methods with its advantages and disadvantages.
