  Steganography is the art and science of covert communication. The secret
information can be concealed in content such as image, audio, or video. This
paper provides a novel image steganography technique to hide both image and key
in color cover image using Discrete Wavelet Transform (DWT) and Integer Wavelet
Transform (IWT). There is no visual difference between the stego image and the
cover image. The extracted image is also similar to the secret image. This is
proved by the high PSNR (Peak Signal to Noise Ratio), value for both stego and
extracted secret image. The results are compared with the results of similar
techniques and it is found that the proposed technique is simple and gives
better PSNR values than others.
