Steganography is the science of “invisible” communication. The pur-pose of Steganography is to maintain secret communication between two parties. The secret information can be concealed in content such as image, audio, or video. This paper provides a novel image steganography technique to hide multiple se-cret images and keys in color cover image using Discrete Wavelet Transform (DWT). There is no visual difference between the stego image and the cover im-age. The extracted secret images are also similar to the original secret images. Very good PSNR (Peak Signal to Noise Ratio) values are obtained for both stego and extracted secret images. The results are compared with the results of other techniques, where single image is hidden and it is found that the proposed tech-nique is simple and gives better PSNR values than others.
