Abstract |
In recent years, various robust watermarking techniques have been proposed for image authentication and tamper detection. In this paper, a novel robust watermarking algorithm for image tamper detection is proposed. Tamper detection and integrity verification are two important aspects of the robust watermarking schemas. Our schema can detect any modification made to the gray image with acceptable accuracy and to improve the security of the proposed scheme two security layers with MD5 and key initial values are employed. The PSNR values of watermarked images are used as a measurement the efficiency of the proposed watermarking algorithm. |
