| Abstract | ||
| The rapid developments in communications systems and image transfer over the internet have led to the need for a new algorithm to hide text messages and images. The research presents dual method and 2-D wavelet transform method. In the first method, the colored image is transferred to Hue Saturation Lightness (HSL), while the second method, the Hue Saturation Lightness image is compressed by using 2-D wavelet transform (2DWT) to the L1, L2, and L3. After using the secret key to hide the compressed image the hidden image is produced. The secret key is a colored image from which statistical gradient of color image is taken and after the statistical gradient or histogram is obtained, it is possible to use cover image with a secret key to hide message under cover image. The results that have been obtained in this proposed algorithm are based on the hidden image of capacity and robustness against attacks, and the generation of the secret key, which the original image can be retrieved without the recipient losing the data in the network | ||
