Keynote - Adversary Modeling in Multimedia Surveillance
Mohan Kankanhalli
Abstract- Multimedia Surveillance systems are used for three purposes of
deterrence, real-time monitoring and forensics. In all of intended
uses, the notion of an adversary who is actively trying to defeat
the system has not been studied much.
We consider surveillance problems to be a set of system-adversary
interaction problems in which an adversary can be modeled as a rational
(selfish) agent trying to maximize his utility. We feel that
appropriate adversary modeling can provide deep insights into the
system performance and also clues for optimizing the system's performance
against the adversary. Further, the system designers should exploit the
fact that they can impose certain restrictions on the intruders and the
way they interact with the system. The system designers can analyze the
scenario to determine conditions under which system outperforms the
adversaries, and then suitably re-engineer the environment under a
"scenario engineering" approach to help the system outperform the adversary.
We show such enhancements to two significantly different surveillance
scenarios using a game theoretic framework and present results of their
adaptation. While the precise enforcements for the zero-sum ATM lobby
monitoring scenario and the non-zero-sum traffic monitoring scenario
are different, they lead to some useful generic guidelines for surveillance
system designers.
Mohan Kankanhalli is a Professor at the Department of Computer
Science at the National University of Singapore. He is also the
Vice-Dean for Academic Affairs and Graduate Studies at the
NUS School of Computing. He obtained his BTech (Electrical Engineering)
from the Indian Institute of Technology, Kharagpur and his MS/PhD (Computer
and Systems Engineering) from the Rensselaer Polytechnic Institute.
He is actively involved in the organization of many major conferences in
the area of Multimedia. He is on the editorial boards of several journals
including the ACM Transactions on Multimedia Computing, Communications,
and Applications, IEEE Transactions on Multimedia, Springer Multimedia
Systems Journal, Multimedia Tools and Applications, and the Pattern Recognition
Journal.
His current research interests are in Multimedia Systems (content processing,
retrieval) and Multimedia Security (surveillance, digital rights management
and forensics).
