A multi-level steganography mechanism using quantum chaos encryption

Recent advances in processing capabilities of hardware devices and 5 g spectrum availability has not only made the life of users heaven but has also instigated intruders to crack the security mechanism easily. Therefore, it is mandatory for the researcher to enhance the level of security incessantly. This paper focuses on developing a multi-level security mechanism that encrypts the text to be transmitted using Quantum cryptography and then encoding it using Huffman compression comprises two levels of security. The resultant data is than hid into noisy pixels of the cover image using the proposed steganography mechanism, consequently enhancing its security level. Also, this paper identifies a Quality Control Parameter (K) for illustration. The higher value of this parameter results in improved embedding capacity with the reduction in pictorial quality and vice versa. The strategies along with its counterpart are implemented in MATLAB-13, and the result shows that the proposed scheme outperforms others in terms of picture quality, Peak Signal to Noise Ratio by almost 10%.
