HIDING SECRET TEXT IN IMAGE USING RC4 AND RIJINDEAL ALGORITHM

In this paper, a method introduced for hiding secret text in image file (JPEG). The proposed method is to embed the secret text message in frequency domain of image. The proposed method contained two stages: the first embedding phase and the second extraction phase. In embedding phase the image transformed from time domain to frequency domain using discrete wavelet decomposition technique (Haar). The text message encrypted twice first: using RC4 algorithm and second using Rijndeal algorithm. Finally; the Least Significant bit (LSB) algorithm used to hide secret message in high frequency. The proposed meth od tested in different images and showed the success of hiding according to (PSNR) equation.
