An image watermarking scheme with tamper detection and recovery

In the aspect of tamper detection and recovery [1] [2], there tire some methods to embed the feature information in host image for recovery. When the host image has been tampered with, the feature information can be used to restore the original image. However, it does not have the ability to verify the ownership of the copyright. In this article, an image watermarking scheme with tamper detection and recovery is proposed. The main goal is to detect and recover the tampered region accurately. In addition, the proposed method has robustness to resist the attacks of JPEG compression and cropping. This is a novel scheme because it has the functions of tamper detection and recovery, while having the main advantage of robust watermarking. Experimental results further demonstrate that our proposed. technique is an efficient method to verify the ownership and recover the tampered region.
