Watermarking, a Mature Technology –retrospect and prospect– [PDF*]

Abstract

  Digital Watermarking has been proposed to manage digital rights, for authentication, to recover lost information, to monitor performance, and other applications. The efforts of many researchers from different disciplines have helped us to understand the basic issues and the challenges, and to help guiding the community toward actual applications. As digital watermarking matures as a technology, it is time to review what has been accomplished and to speculate what may be expected. In this talk, we will try to highlight the key development in digital watermarking, to examine the effectiveness in some applications, and to offer some thoughts regarding future development of digital watermarking.

The Marriage of Cryptography and Watermarking - Bene cial and Challenging for Secure Watermarking and Detection

Professor Ahmad-Reza Sadeghi

Abstract

  Multimedia applications deploy various cryptographic and watermarking techniques to maintain security. In this context, we survey the main work on two promising approaches for secure embedding and detection of a watermark into digital data in an untrusted environment, and we point out some associated challenges. The first approach, termed as Zero-Knowledge Watermark Detection (ZKWMD), allows proving that a watermark is detectable in certain content, without jeopardizing the security of the watermark. ZKWMD protocols are very useful primitives for direct proofs of authorship (i.e., without online involvement of a trusted third party) and dispute resolving in distributed systems. The other approach concerns a Chameleon-like stream cipher that achieves simultaneous decryption and fingerprinting of data, and can serve as the second line of defense for tracing illegal distribution of broadcast messages, termed as Fingercasting.

Short Bio

  Ahmad-Reza Sadeghi is full Professor and head of the Chair for System security at Horst Görtz Institute for IT Security at Ruhr-University Bochum, Germany.

  He has received his MSc in Mechanical and Electrical Engineering and his PhD in Computer Science. Prior to academia he has been with several IT and Telecommunications enterprises in Research and Development. Currently he is leading several research and development projects on design and implementation of trustworthy computing platforms based on trusted computing technology as well as cryptographic mechanisms and privacy preserving systems. He serves as program committee member of variety of conferences and workshops on security and cryptography.

Research Interests

  His research interests include security architectures, Trusted Computing, privacy enhancing technologies, and design of cryptographic protocols.

Digital Image Forensics [PDF*]

Professor Hany Farid

Professor of Departments of Computer Science
Dartmouth College, USA

Abstract

  The compositing of two or more people into a single image is a common form of manipulation. We describe how such composites can be detected by estimating a camera's intrinsic parameters from the image of a person's eyes. Differences in these parameters across the image are used as evidence of tampering.

Short Bio

  Hany Farid received his undergraduate degree in Computer Science and Applied Mathematics from the University of Rochester in 1989. He received his Ph.D. in Computer Science from the University of Pennsylvania in 1997. Following a two year post-doctoral position in Brain and Cognitive Sciences at MIT, he joined the Dartmouth faculty in 1999. Hany is a Professor of Computer Science and Associate Chair. Hany is the recipient of an NSF CAREER award, a Sloan Fellowship and a Guggenheim Fellowship.

  From working with federal law enforcement agencies on digital forensics, to the digital reconstruction of Ancient Egyptian tombs, Hany works and plays with digital media at the crossroads of computer science, engineering, mathematics, optics, and psychology.

Research Interests
