Abstract:

Self-organization is one of the most important features observed in social, economic, ecological and biological systems. Distributed self-organizing systems are able to generate emergent global behaviors through local interactions among individuals without a centralized control. Such systems are also supposed to be robust, self-repairable and highly adaptive. However, design of self-organizing systems is very challenging, particularly when the emerged global behaviors are required to be predictable.

Morphogenesis is the biological process in which a fertilized cell proliferates, producing a large number of cells that interact with each other to generate the body plan of an organism. Biological morphogenesis, governed by gene regulatory networks through cellular and molecular interactions, can be seen as a self-organizing process. This talk presents a methodology that uses genetic and cellular mechanisms inspired from biological morphogenesis to self-organize collective engineered systems, such as multi-robot systems and modular robots. We show that the morphogenetic approachis able to self-organize collective systems without a centralized control, which is nevertheless able to generate controlled global behaviors. Meanwhile, we demonstrate that the global behavior is adaptable to changing environments.

Topic 2: Image Steganography, Watermarking and Forensic Techniques for secure communication and protection of image content
Speaker: Professor Anthony T.S. Ho
, Head of Department of Computing, University of Surrey
Chair: Jun Zhang (张军), Email:

Time: 10:30-11:30 AM, Monday, May 13th, 2013
Venue: Lecture Hall 207, School of Information Science and Technology, East Campus, SYSU


Abstract:

The tremendous growth of advanced telecommunication and Internet technologies in the past two decades has led to the proliferation of multimedia content for digital transmission and storage. The talk will give an overview of data hiding techniques and their applications to digital images. For example, image steganography for secure communication of secret messages via an open channel, and digital watermarking for protection and authentication of content integrity. Finally, the talk will also introduce image forensic techniques for camera identification from captured images and forgery detection of images, which are currently attracting a great deal of attention from the research community.

Biography:

Professor Anthony T.S. Ho
holds a Personal Chair in Multimedia Security and is currently Head of Department of Computing, University of Surrey since 2010. He also leads the Multimedia Security and Forensics research group in the Department. He was the recipient of the Institution of Engineering and Technology (IET) Innovation in Engineering Award under he Security category for his research and commercialization work on digital watermarking in 2006.

Professor Ho obtained his BSc (Hons) in Physical Electronics from Northumbria University in 1979, his MSc in Applied Optics from Imperial College London in 1980 and his PhD in Digital Image Processing from King's College London in 1983. After graduation, he worked in technical management positions in industry for 11 years in the UK and Canada.

From 1994 to 2005, Professor Ho was a Senior Lecturer and then Associate Professor at Nanyang Technological University (NTU), Singapore. While at NTU, he co-founded and became CEO of DataMark Technologies (DMT) in 1998, a company specialises in digital watermarking and steganography. DMT is now a subsidiary of Singapore Technologies Engineering. Professor Ho has published more than 130 articles in international journals and conference proceedings as well as 8 international patents granted related to watermarking and steganography. He recently received a best paper award for a co-authored conference paper on camera model identification from IEVC 2012. He is the Editor-in-Chief of the international journal Information Security Technical Report published by Elsevier.

Professor Ho was General Chair for the 8th International Workshop on Digital Watermarking (IWDW) held at the University of Surrey in 2009 and co-Editor for two Springer Proceedings on Digital Watermarking from IWDW08 and IWDW09. He is a Fellow of Institution of Engineering and Technology (FIET), Fellow of Institute of Physics (FInstP), Fellow of British Computer Society FBCS) and Senior Member of IEEE.
