Dr. Yi Mu Associate Professor, School of Computer Science and Software Engineering Director, Centre for Computer and Information Security Research University of Wollongong ____________________________________________ RFID Security – Threats and Solutions Radio frequency identification (RFID) systems are widely applied to identify an object from its digitalized information attached and the associated information stored in a server. RFID systems are facing various security threats due to lack of protection. Protecting RFID systems against external attacks is a very challenging task, since the computational power of RFID systems is generally very weak. In this talk, I will firstly outline major security threats to RFID systems in various RFID environments. Then, I will describe current research toward practical solutions to RFID security. About Dr. Yi Mu Yi Mu received his PhD from the Australian National University in 1994. He currently is an associate professor at School of Computer Science and Software Engineering and the director of Centre for Computer and Information Security Research, University of Wollongong. Prior to joining University of Wollongong, he was a lecturer at the School of Computing and IT, University of Western Sydney, and a senior lecturer at the Department of Computing, Macquarie University. He has published approximately 200 research papers in various fields including information security, cryptography, and quantum informatics. He is the editor-in-chief of International Journal of Applied Cryptography and serves as editor for seven other international journals. He has also served as a member of program committees for more than 80 international conferences. He is a senior member of the IEEE and a member of the IACR. Dr. Yanchun Zhang Director, Centre for Applied Informatics Research School of Computer Science & Mathematics Victoria University ____________________________________________ Web Community Mining Due to the inherent correlation among Web objects and the lack of a uniform schema of web documents, Web community mining and analysis has become an important area for Web data management and analysis. The research of Web communities spans a number of research domains such as Web mining, Web search, clustering and text retrieval. In this talk we will present some recent studies on this topic, which cover finding relevant Web pages based on linkage information, discovering user access patterns through analyzing Web log files, co-clustering Web objects and investigating social networks from Web data. The algorithmic issues and related experimental studies will be addressed. Some research directions are also to be discussed.
