Usha B.a, N.ksrinath, Ravikumar C N, Vismayas P . Cognitive Prediction of the Most Appropriate Image Steganography Approach. International Journal of Computer Applications. 121, 8 ( July 2015), 42-45. DOI=10.5120/21564-4599
In the light of growing technological advancements, data security has become a matter of great concern. This in turn has reiterated the significance of fields like cryptography and steganography to modify or hide secret data. The conventional methodologies of steganography and cryptography are not designed to utilize the semantic meaning of data. Even though these traditional methods offers ample security, it fails to personalize the whole process and make it dependent on the requirements as specified by an individual. Thus the idea of cognitive cryptography took birth. The field of cognitive science has been progressing at a fast rate and deals with decision making. In this paper, the idea of cognitive cryptography has been adapted to give rise to cognitive steganography. The application developed here aims at deciding the most suitable steganography approach (among the chosen four algorithms) for hiding input data, by taking into account its semantic meaning and the intended application. The development of such an algorithm overcomes the shortcomings of traditional techniques in terms of computational complexity, memory usage, image distortion and effective bandwidth utilization.
