Cascaded DNA cryptography and steganography

Abstract

The redundancy in English words helps the unauthorized entity to guess the cipher text. The DNA sequences do not follow such properties. It means the conversion of message to DNA sequences make it robust against attacks. This paper performs the DNA cryptography and then hides the DNA sequence in to the random frame of a video. The result analysis shows that the frame is imperceptible. The video seems to be same. The enhancement in PSNR value and reduction in MSE shows the effectiveness of the technique.
