In this paper, we present a new algorithm for RGB image based steganography. Our algorithm introduces the concept of storing variable number of bits in each channel (R, G or B) of pixel based on the actual color values of that pixel: lower color component stores higher number of bits. Our algorithm offers very high capacity for cover media compared to other existing algorithms. We present experimental results showing the superiority of our algorithm. We also present comparative results with other similar algorithms in image based steganography.
