| Abstract | ||
| An image hash is a short signature code of the image that preserves in many fields like image encryption and image forgery detection. In image forgery detection, its semantic information under allowable changes made to it, while at the same time differentiates it from a different image. It help in detection the changing the original image. In this paper the hashing image method and encoding combined to detected any small change or forgery in the image. The SHA-256, Run Length Encoding RLE, and RC4-AES hybrid encryption used to generate the secure hash code for the images and stored them into a private database then used later to detect forged images. A best results of recognized the forged image with fast time of detection and hash code generation. | ||
