Summary:Steganography is data hiding technique that is mostly used. It uses cover object of type text, images, and videos. The paper presents a new devised algorithm to hide text in any colored image of any size using Huffman encryption and 2D Wavelet Transform. We presented simulated results which prove that there is very negligible image quality degradation. We used PSNR metric for this purpose. The subject algorithm also proved secure as Huffman table is required to decode the information.
