The In today"s era with increase in the use of internet and networking devices, there is an increase in demand for more secure data communication.This problem has led to development of hybrid security mechanisms.Various techniques are available in literature that makes use of different steganography and cryptographic mechanisms which has certain pros and cons.In this paper, we propose a new hybrid security mechanism that tries to choose the best cryptographic and steganography mechanism.In addition, to increase the embedding capacity of the proposed mechanism, Huffman encoding scheme is used.The proposed strategy is implemented in MATLAB-09.In order to check the efficacy of the proposed technique three types of analysis were performed named as: security, robustness and efficiency analysis.It is found from the simulation and results that the proposed scheme outperforms other techniques in literature in every aspect.
