| Abstract | ||
| In this paper, a method for hiding cipher text in an image file is introduced . The proposed method is to hide the cipher text message in the frequency domain of the image. This method contained two phases: the first is embedding phase and the second is extraction phase. In the embedding phase the image is transformed from time domain to frequency domain using discrete wavelet decomposition technique (Haar). The text message encrypted using RSA algorithm; then Least Significant Bit (LSB) algorithm used to hide secret message in high frequency. The proposed method is tested in different images and showed success in hiding information according to the Peak Signal to Noise Ratio (PSNR) measure of the the original image . | ||
