“Trust Enhanced Security”
SoCCaN 2008 Keynote

The notion of trust has been around for many decades (if not for centuries) in different disciplines in different disguises. In particular, the concept of trust has been studied extensively in various disciplines such as psychology, philosophy, economics, sociology as well as in technology. Yet we do not have a clear handle on this concept of trust which is increasingly becoming significant in our information economy and the Internet world. It is often quoted (and probably correctly) that trust is a key foundation stone of the information security world. In security, the concept of trusted systems has at least been around publicly for some 25 years and more recently “trustworthy computing” has taken a centre stage, with
the launch of major initiatives in trustworthy computing by several major players in the information technology arena. In this talk, we will take a look at the concept of trust in the secure computing world and see some of the challenges and pitfalls involved. We will try to extract some fundamental issues in trust that could help in the design of secure systems in a pervasive computing environment. We will then introduce the notion of “trust enhanced
security” and discuss how such a paradigm can be used to develop trust enhanced secure
wireless mobile ad hoc networks.
Vijay Varadharajan is the Microsoft Chair and Professor of
Computing at Macquarie University. He is also the Director of
Information and Networked System Security Research. Previous to this,
he was the Foundation Chair Professor and Head of School of School of
Computing and IT at UWS Nepean. Prior to taking up this appointment,
he was responsible for Security Research at Corporate Hewlett-Packard
Labs based at HP Labs Europe in Bristol, UK, for a number of years. He
has published more than 275 papers in International Journals and
Conferences and has co-authored and edited 8 books on Security,
Networks and Distributed Systems. His current research interests are in distributed system security, network security, mobile agent security, trusted computing and secure peer to peer applications. He is on the Editorial Board of several journals including the ACM Transactions on Information System Security and The International Journal of Information Security (Springer). He has been a member of the Board of Advisors in Trusted Computing Platform Association (TCPA) (USA) and is on the Microsoft Trustworthy Computing Advisory Board (USA). He has held several invited Visiting Professorships including INRIA Research Labs (France), British Telecom Labs (UK), Chinese Academy of Sciences, Institute of Mathematical Sciences (NUS, Singapore), Indian Institute of Sciences as well as Visiting Senior Research Scientist at Microsoft Research Cambridge, UK. He is a Fellow of the British Computer Society (FBCS), a Fellow of the IEE (FIEE), a Fellow of the IMA (FIMA), a Fellow of the Australian Institute of Engineers (FIEAust), and a Fellow of the Australian Computer Society.
“Video Quality and Video Databases”
Plenary Talk
1:30pm - 2:30pm, August 7, 2008
Al Bovik
(IEEE Fellow, OSA Fellow, SPIE Fellow)
Curry/Cullen Trust Endowed Chair Professor
Laboratory for Image and Video Engineering (LIVE)
The University of Texas at Austin
Digital video is the most voluminous and increasingly important data content being transported over the public IP network. Since most of this data is intended for human visual consumption, service and content providers are increasingly concerned with measurement of video perceptual quality. In this talk I draw analogies between the perception of visual quality and the classical theory of information communication. However, the picture is clouded by the fact that, unlike most engineering problems, the receiver and transmitter are difficult to
access, model or even define.
I will describe my philosophy regarding these models and our recent efforts on quality assessment of visual signals. I’ll begin with our successful still image algorithms, the Structural SIMilarity (SSIM) Index and the Visual Information Fidelity (VIF) Index. I will then describe recent efforts on the more complex problem of Video Quality Assessment (VQA). This includes extending the ideas of SSIM and VIF to detect quality along motion trajectories, and efforts to create publicly-available Video Quality Assessment Databases, include large-scale human subjective studies.
Al Bovik currently holds the Curry/Cullen Trust Endowed Chair
Professorship at The University of Texas at Austin. His recent interests are
in the areas of perceptual image and video processing and computational
vision. He has published over 500 technical articles in these areas and holds
two U.S. patents. He is also the author of The Handbook of Image and
Video Processing, Modern Image Quality Assessment, and two up-coming
books, The Essential Guides to Image and Video Processing.
Al has received a number of major awards from the IEEE Signal
Processing Society, including: the Education Award (2007); the Technical Achievement Award (2005), the Distinguished Lecturer Award (2000); and the Meritorious Service Award (1998). He is also a recipient of the IEEE Third Millennium Medal (2000), and two journal paper awards from the Pattern Recognition Society. He is a Fellow of the IEEE, a Fellow of the Optical Society of America (OSA), and a Fellow of the Society of Photo-Optical and Instrumentation Engineers (SPIE).
Al served on the Board of Governors of the IEEE Signal Processing Society (1996-1998), as Editor-in-Chief of the IEEE Transactions on Image Processing ( 1996-2002), and
created and served as the first General Chairman of the IEEE International Conference on
Image Processing, held in Austin, Texas, in November, 1994.
