N2 - In this paper, a block wise image authentication scheme using a semi-fragile watermark is proposed. The proposed scheme determines integrity of the image, detecting regions suffered some content modifications and altered region can be recovered without the original image. In the proposed scheme, the original image is divided into two regions: Region of Interest ROI, which is important region that requires protection against malicious modification and Region of Embedding ROE, which is the rest of the image where watermark sequence is embedded. The proposed scheme is evaluated from the several points of view: watermark imperceptibility, accuracy of tamper area detection, quality of recovered regions and robustness to nointentional manipulations, such as JPEG compression. Experimental results show excellent performance of the proposed scheme.
