Digital Watermarking for High-Quality Imaging

        We are seeing an emerging use of digital watermarks as the means for authentication and copyright protection of multimedia data. There are active researches reported in current literature on digital watermarking techniques. Among the applications, the use of digital watermarks in protecting high-quality, high-valued images is one of the most promising and important applications, and certainly poses many challenges. In this paper we present several classes of digital watermarking techniques, address their uses in high-quality imaging applications, specify the requirements and summarize the current research efforts in the Image Library Applications group of the IBM Thomas J. Watson Research Center on digital watermarking.
