摘要：

This paper proposes a modified and simple method for high capacity Steganography in case of color images. This algorithm is usually based on wavelet fusion technique which was not attempted for color images and it proves to be a simplest method than other techniques or algorithms for color images. Even though it uses transform domain technique which only provides robustness against attacks and eavesdropping and it is known that spatial domain techniques usually meets the capacity and quality requirements. In this paper the transform domain technique (Wavelet Transform) is used to attain high capacity along with security and maintains the quality of the cover image which act as the key feature of this work.This improvement in the capacity-quality tradeoff is analyzed and proved experimentally in this paper.
