Abstract

In the current world when entire web contains most of multimedia data then protection of that data is our major concern. Different techniques are discovered and developed from time to time to encrypt and decrypt the images for making them more secure. Most of the encryption technique uses secret key to prevent the data from an unauthorized access. In this paper, we study different research papers on various encryption and steganography techniques. Encryption and steganography techniques provides security of images from intruder.
