Most steganography methods suffer from many problems that effect on
their 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 method
to hide audio file (WAV format) in image (BMP format) that overcomes most of
these problems. Also the proposed method aims to meet most the requirements of
any steganography system (like capacity, security and undetectability). It depends
on finding the similarity between the embedded data blocks and others in the
cover-image. It can be used as a powerful tool to get a high capacity data
embedding and a less distortion stego-image, where the PSNR for the stego-image
is large.
