At present, information is being communicated and proceeds automatically on a large scale. Hence, the required measures for secure storage and transporting of the information are increased. The protection of the information is necessary to guard economic interests, to prevent fraud, to guarantee the privacy of the citizen, etc.
In this paper, a new steganographic system with high capacity is proposed. The proposed algorithm chooses wavelet transform techniques for embedding to achieve a robust system. The main idea of the proposed system is called the wavelet based fusion. In this method, the wavelet decomposition of the cover image and the secret image are merged into a single result called stego-image.
