The network security is becoming more important as the amount of data being exchanged on the Internet is increasing. Security requirements are necessary both at the final user level and at the enterprise level, especially since the massive utilization of personal computers, networks, and the Internet with its global availability. Steganography play an important role for secure communication in network security. When the authors combine the property of steganography with cryptography, they can achieve more secure complex system. This paper work proposed a frame work for secure message communication, it uses multilevel security techniques for securing secret data as well as provision for user authentication and control eavesdropping. This paper also gives comparative study with current techniques.
