A New Algorithm for Less Distortion and High Capacity Steganography Model Using Blocks-Based Method


Most steganography methods suffer from many problems that effect ontheir efficiency and performance. Some of these are the capacity of cover media,the distortion of cover media, and etc. In this paper we are proposed a new methodto hide audio file (WAV format) in image (BMP format) that overcomes most ofthese problems. Also the proposed method aims to meet most the requirements ofany steganography system (like capacity, security and undetectability). It dependson finding the similarity between the embedded data blocks and others in thecover-image. It can be used as a powerful tool to get a high capacity dataembedding and a less distortion stego-image, where the PSNR for the stego-imageis large.
