Abstract

Image steganography is used to hide the secret message under a cover image in order to enhance the
security. There are several techniques proposed which has focused on the security issue in their work. In this paper, the
proposed method uses three different techniques such as Huffman coding, DNA and ST. Initially, Huffman is applied over
the text for the compression, and then DNA is applied over the compressed data for the encryption and lastly State
Transition algorithm is used for updating the location in the image. The application of these algorithms is to provide
high security in comparison with the traditional algorithms. Total three images will be used for the evaluation of
traditional and proposed techniques where the message bit varies from 50 to 100. The parameters PSNR and MSE are
used for the evaluation of their performance.
