In this paper, discuss about the data hiding using the wavelet approach is better technique in stegnography techniques. optimization techniques are better results provides for the data hiding in stenography. In Discrete Wavelet Transform, HAAR Wavelet gives the excellent peak signal to noise ratio (PSNR) and less computation time. In optimization, particle swarm optimization technique is gives excellent better result in case of PSNR ratio.In spatial domain, common useful technique is least significant bit(LSB) gives better result in case of data payload capacity and less computation time. In paper mentioned, all above techniques with compare to other related techniques useful in stegnography.
