Abstract
This paper presents a steganographic technique using the theory of Brownian motion. In the beginning, the Brownian Based Scrambling procedure introduces traces of non linearity in the carrier medium so as to introduce one layer of security. A lighter pixel (in terms of its intensity) is presumed to experience a faster movement than the heavier ones. The above stated concept is based on the randomized scrambling strategy which is usually chaotic in nature. It actually reflects the strategy of chaos generation in the image medium. The ‘key’ is generated from the Brownian theories and is being utilized in the Power Modulus Scrambling strategy to increase the security level. In addition, the embedding technique, i.e. Pixel Insertion Methodology is also dependent on certain correlation factors of Brownian motion. The performance has been worked out to establish the efficacy of the algorithm. This whole procedure supports high embedding capacity. The experimental results show that the proposed technique performs better or at least at par with respect to many of the existing steganographic techniques. The results have been tested against various benchmarks, as illustrated in the section of experimental results. This approach can be used to provide an additional layer of protection to any system that communicates important data/information through any kind of globally accessed medium. Moreover, this approach serves its purpose of providing seamless security between sender and receiver without producing any distortion in the images. This explicit concept may be used in cyber-security for prevention of unauthorized access of information.
