Paper Abstract

A copyright protection technique without using the original image in the process of copyright verification is demanded in most applications. In addition, robustness, imperceptibility, security, and unambiguity are also essential requirements for a copyright protection technique. In this paper, a robust copyright protection scheme for digital images, based on the low-band characteristic, is proposed to meet these requirements. Experimental results show that the proposed scheme not only can clearly verify the copyright of the digital images, but also is more robust than existing schemes against several attacks such as JPEG lossy compression, noise adding, sharpening, and blurring.
