State-of-the-art Review on Steganographic Techniques

Abstract

Information security is one of most important concern in any communication. There are number of security attacks related to information security and number of techniques has been implemented to prevent these attacks. Data hiding is related field to information security. Data hiding can be achieved be using Digital Steganography. Digital Steganography is art of hiding secret messages behind the innocent looking digital media. In this paper we have done state-of-the-art survey on image steganographic techniques and steganographic techniques used with different cryptographic algorithms, to provide extra layer of Security.
