Pixel Indicates, Standard Deviates: A Way for Random Image Steganography

Abstract: The last few decades have seen a tremendous growth in computing machines as well as the digital information with internet expansion. The transmission and storage of this huge volume of information is a high priority issue and has lead to the evolvement of information hiding and cryptographic techniques. Cryptography scrambles the message to be transmitted safely and different key sizes implement different security levels. Steganography is an information hiding technique and embeds the information in undetectable files like images or texts such that their very presence is not detected with the naked eyes. Cryptography and steganography have their own advantages and disadvantages and though each is resistant to attacks in their own ways, a combination of both results in a better cryptosystem and is a chief domain of research these days. Completely different from other methods, this paper makes use of the basic traits of statistical distribution given by mean and standard deviation; the basic building block for this paper. Embedding is done by adopting LSB substitution and PI. Bits to be infixed are decided by some prerequisites for increasing ramification. Justification for this algorithm is given by rudimentary of images along with bits per pixel and capacity of embedding. This paper promises high security and enhanced robustness as well.
