Abstract EN
One of the methods introduced for accomplishing hidden communication is the steganography technique.
Steganography is an important area of research in recent years involving a number of applications.
It is the science of embedding information into the cover image, text and video without causing statistically significant modification to the cover image.
This paper proposes an image steganography system ; it hides the gray level image on another gray level image by using optimal resilient Boolean functions.
First, it starts by encrypting secret image by using optimal resilient function then embedding encrypted image inside a cover image by using DCT.
The new proposal system of image encryption has been investigated by encrypting the powerful frequency coefficients in DCT using a saturated best resilient Boolean function (SRB) that constructed by Zhang's construction.
The simulation results of the proposal system have calculated the peak signal to noise ratio (PSNR) and the correlation test in order to compare between the cover image and the stego image and the results have also calculated the correlation test between the secrete image and the extraction image as a parameter of robustness.
The experimental results have showed that the images can be embedded by steganography and optimal resilient Boolean function with smaller correlation compared to the original secret image and the extraction image.
Finally, it is observed that for all images, PSNR is greater than 55.
