Cryptography and Steganography: New Approach

Abstract

Digital communication witnesses a noticeable and continuous development in many applications in the Internet. Hence, secure communication sessions mustbe provided. The security of data transmitted across a global network has turned into a key factor on the network performance measures. So, the confidentiality and the integrity of data are needed to prevent eavesdroppers from accessing and using transmitted data. Steganography and Cryptography are two important techniques that are used to provide network security. In this paper, we survey a number of methods combining cryptography and steganography techniques in one system
