The maintenance of privacy and secrecy of information in modern communication is accomplished through steganographic technique. Spatial domain techniques are popular ones in image steganography. In this paper, we propose hybrid steganography (HDLS) which is an integration of both spatial and transform domains. The cover image as well as the payload is divided into two cells each. The RGB components of cover image cell I are separated and then transformed individually from spatial to transform domain using DCT/DWT/FFT and embedded in a special manner, the components of cell II retained in spatial domain itself. The proposed algorithm has better PSNR and security as compared to existing techniques.
