Information security model using data embedding technique for enhancing perceptibility and robustness

Abstract

Information concealing using steganography is simple, but to maintain its security, perceptibility, robustness, embedding capacity and better recovery of both covers as well as secret data are the major issues. This paper is focused on the improvement in all these major issues. The proposed technique embedded the image and audio as secret data into the randomly selected frames of the video using multi frame exploiting modification direction (MFEMD) algorithm. Hence, it is very difficult to understand in which part of video, data is hidden. At the receiver end, we have used the forensic tool for authentication to improve the data security. Furthermore the obtained simulation results are found to be better than any other existing methods in terms of good visual recovery of both original video and secret data, embedding capacity, security of hidden secret data. Different types of attacks are applied on stego video during transmission like visual, chi-square, histogram, etc. to improve the perceptibility and robustness of secret data.
