Abstract

With the advancement of data communication over computer network, the security of info become a major issue. A
steganography is a technique of hiding multimedia info in an audio, video and image. Different technique of steganography
are least significant bit (LSB) technique, discrete cosine transform (DCT), spread spectrum, discrete wavelet transform (DWT)
and most efficient Hash LSB are briefly described. A comparative analysis is made to demonstrate by computing peak signal to
noise ratio (PSNR) and mean square error (MSE). The stego images are tested by transmitting them and embedded data are
successfully extracted by the receiver.
