An Innovative Approach for Image Encryption and Decryption

Abstract

Many digital services require reliable security in storage and transmission of digital images. Due to the rapid growth of the internet in the digital world today, the security of digital images has become more important and attracted much attention. The prevalence of multimedia technology in our society has promoted digital images to play a more significant role than the traditional texts, which demand serious protection of users' privacy for all applications. Encryption and steganography techniques of digital images are very important and should be used to frustrate opponent attacks from unauthorized access. Digital images are exchanged over various types of networks. It is often true that a large part of this information is either confidential or private. Encryption is the preferred technique for protecting the transmitted data. In this paper, a new approach is discussed for encryption and decryption.
