In this paper, the problem of detecting unauthorized changes to the content of a digital image, identifying distorted parts of the image, and partially recovering lost information are considered. The basic approach for tamper detection is a watermarking procedure where the type and parameters of the distortion of the watermark can be used to infer fraud, locate the damaged parts of the image, and to recover them. In this paper, a watermarking procedure is used that allows manipulation of different size ratios of the image-container and watermark. Using this technique, a self-embedding procedure is developed where part or all of the original image are embedded as a watermark. The effectiveness of proposed technique is shown through numerical experiments.
