摘要：Steganography is the science of “invisible” communication. The purpose of Steganography is to maintainsecret communication between two parties. The secret information can be concealed in content such asimage, audio, or video. This paper provides a novel image steganography technique to hide multiple secretimages and keys in color cover image using Integer Wavelet Transform (IWT). There is no visual differencebetween the stego image and the cover image. The extracted secret images are also similar to the originalsecret images. Very good PSNR (Peak Signal to Noise Ratio) values are obtained for both stego andextracted secret images. The results are compared with the results of other techniques, where single imageis hidden and it is found that the proposed technique is simple and gives better PSNR values than others.
