Developing a Highly Secure and High Capacity LSB Steganography Technique using PRNG

Abstract

Being a modern way of secret messaging, steganography has become one of the trending topic for researchers and scientists. Using image in data secrecy is most common among all other ways of digital communication. In steganography, a carrier object behaves as a cover for the secret object such that intruders are not aware of its existence. Thus, it is important to create a steganography technique which is highly secure and also has a high data hiding capacity. In the technique proposed, each pixel has an enhanced capacity of 3-6 bits. This capacity is directed by the most significant bits of the indicator channel. Use of PRNG has made this technique more secure. The results achieved by the experiment signify the profoundness of this technique.
