Crossing the Line: Cyberspace Terrorism and Real-World Targets in Fact and Fiction

Prof. Larry Constantine, IDSA
Madeira Interactive Technologies Institute


 A precision targeted cyber-weapon, allegedly the work of the Israeli and American intelligence communities, destroys high-speed centrifuges at Natanz in Iraq. A consortium of hackers hanging out in an online cyberworld remotely cripples electric generators at a coal-fired power plant in the American southwest. What really happened? And what could yet happen? The boundaries between the virtual and the real are blurring, as sophisticated software now crosses the line from digital action to physical destruction. This keynote will look at what might be learned from the real-world exploits of the sophisticated software worm known as Stuxnet and from the speculations and extrapolations of its fictional cousins. The implications for policy and practice in cyber-security and cyber-warfare will be considered.

EEG-enabled Personalized Digital Experience in Co-Space

Olga Sourina
School of Electrical and Electronic Engineering
Nanyang Technological University


EEG-based immersion is a new direction in research and development on human computer interfaces. It has attracted recently more attention from the research community and industry as wireless portable EEG devices became easily available on the market. EEG-based technology has been applied in anesthesiology, psychology, serious games or even in marketing. As EEG signal is considered to have a fractal nature, we proposed and developed a novel spatio-temporal fractal based approach to the brain state quantification. We discuss the real-time algorithms of emotion recognition and concentration level recognition and its integration in human-computer interfaces of EEG-enable applications. The experiments on evoking emotions by music and sound stimuli are described. Models and algorithms of quantification of brain responses to external stimuli are discussed. The algorithms of the brain state quantification including emotion recognition would advance research on human computer interaction bringing the quantification methods and algorithms as new tools in medical, entertainment, and even digital art methodology applications, and allowing us an integration of the brain state quantification algorithms in the human computer interfaces. EEG-enable applications such as serious games, emotional avatar, music therapy, music player, storytelling, etc are demonstrated.

Non-traditional Modelling

Prof. Brian Wyvill,
University of Victoria, Canada

Abstract: Computer models and triangle meshes have become synonymous in the computer graphics community, yet many other representations exist.  GPU hardware for processing and scanning hardware for capture all support this methodology over anything else. 

 In this talk I explore the possibility that the implicit modeling approach has some advantages over current popular techniques. The BlobTree structure is an extended CSG tree that combines a scene graph with nodes that relate skeletal implicit models, such as blending, CSG and deformations. Recent work in sketch-based modeling and the introduction of new field functions and operators permits a user to rapidly prototype implicit models without the drawbacks that became associated with this methodology in the 1980s and 1990s.

 Unlike the ubiquitous triangle mesh, the BlobTree is a volume representation. This implicit representation requires no further complex algorithms to segment it into a parts hierarchy, and sketch-based interfaces allow direct manipulation taking into account both local and global deformations. Additions and deletions at a high level or at a detailed level are simple to perform and the surface is an exact representation of the designer’s concept. Classifying points as inside or outside requires a function evaluation and collision response and contact deformations are easy to implement.  None of the above is true for triangle mesh representations.

 Content creators want to build more complex models in an efficient fashion.  One way of accomplishing this is to develop prototypes in a networked collaborative system. Passing large meshes across a network becomes a bottleneck in such a system.  On the other hand, implicit models can be represented by a small hierarchy (the BlobTree). Information needed to build this can be highly condensed.   With the advent of more local processing power, traversing a tree structure to produce a complex implicit model can be done interactively for highly complex models.

 The next generation of GPU seems to be going in the direction of supporting more general purpose computing in a massively parallel manner.  We look forward to hardware support for functional models and the exploitation of their many advantages.


Brian Wyvill graduated from the University of Bradford, Uk with a PhD in computer graphics in 1975.  As a post-doc he worked at the Royal College of Art and helped make some animated sequences for the Alien movie.   He emigrated to Canada in 1981 where he has been working in the area of implicit modeling, sometimes with his brother Geoff Wyvill (University of Otago). He is also interested in sketch based modeling and NPR and enjoys combining these areas of research.  Brian spent a quarter of century at the University of Calgary and is now a Professor and Canada Research Chair at the University of Victoria, in British Columbia.

Cyberwords Architectural Design and  Applications

Prof. Tosiyasu L. Kunii
University of Tokyo, Japan


Cyberworlds are being formed in cyberspaces as computational spaces.  Now cyberspaces are rapidly expanding on the Web either intentionally or spontaneously, with or without design.  Widespread and intensive local activities are melting each other on the web globally to create cyberworlds.  The major key players of cyberworlds include e-finance that trades a GDP-equivalent a day and e-manufacturing that is transforming industrial production into Web shopping of product components and assembly factories.  Lacking proper theory and design, cyberworlds have continued to grow chaotic and are now out of human understanding and control.  This tutorial first presents a generic theoretical framework and design based on algebraic topology and differential topology.

As high demand applications, the tutorial looks at cloud computing allocations. Emergence of cloud computing combined with its high availability through smart devices such as smart phones and media is requiring a transparent and highly universal modeling of the worlds in cloud computing to overcome combinatorial explosion of computing, that are actually cyberworlds.  Hence, appropriate scalable modeling of cyberworlds meets the requirements effectively.  Extreme diversities, versatility and dynamism of cloud computing applications are shown to be supported by the cyberworld modeling in an incrementally modular abstraction hierarchy (IMAH) with homotopy extension property (HEP) and homotopy lifting property (HLP).

Synthetic biometrics for training users of biometric and biomedical systems

Prof. S.N. Yanushkevich

 U of Calgary, Canada


Synthetic biometrics are understood as generated biometric data (physiological and behavioral characteristics of humans in the form of visual, audio or other information) that are meaningful for biometric systems. This synthetic data replicate possible instances of otherwise unavailable data such as corrupted or distorted data. For example, facial images, acquired by video cameras, can be corrupted due to their position and angle of observation (appearance variation), as well as lighting (environmental conditions), camera resolution, and other parameters (measurement conditions).

Synthetic biometrics can also be interpreted in terms of a forgery of biometric data. Properly created artificial biometric data provides an opportunity for the detailed and controlled modeling of a wide range of training skills, strategies, and tactics that enable detecting intrusions, spoofing or other extreme scenario. An example of the application of synthetic biometrics is training users of a physical access control system. The modeling and simulation of biometric data is used for efficient support of security personnel training in dealing with customer identification under conditions of uncertainty.

The other example is biomedical facilities such as remote monitoring of patient biometrics (physiological and behavioral patterns) in hospitals or care units. Simulation of various monitored data, as well as extreme scenarios is aimed at developing the particular decision making skills of the system personnel. Such modeling requires developing specific training methodologies and techniques, including virtual environments.


Svetlana N. Yanushkevich received the M.S. (1989) and PhD (1992) in electrical and computer engineering from the State University of Informatics and Radioelectronics, Minsk, Belarus, and Habilitation degree (1999) in Technical Sciences from Warsaw University of Technology, Poland.
