Audio steganography is the science of hiding audio information into the cover image without causing statistically significant modification to the cover image. In this paper, a new steganography method to hid radio signal in color images is presented. The proposed method combines Least Significant Bit (LSB) which is the most simple and efficient technique used for audio steganography, Discrete Cosine Transform (DCT), and Haar wavelet transform. Firstly, the background of the cover image is separated from details, and then transforms it to Luminance-chrominance components.
