Speakers and abstracts

Alfred Kobsa: Professor at Donald Bren School of Computer and Information Sciences, University of California, Irvine, USA

Privacy-Enhanced Personalization

Abstract: Personalized interaction with computer systems can be at odds with privacy since it necessitates the collection of considerable amounts of personal information. Numerous consumer surveys revealed though that computer users are very concerned about their privacy online. The collection of personal data is also subject to legal regulations in many countries and states. This talk presents work in the area of Privacy-Enhanced Personalization that aims at reconciling personalization with privacy through suitable human-computer interaction strategies and privacy-enhancing technologies.

Alfred Kobsa

Biography: Alfred Kobsa is a Professor in the Donald Bren School of Information and Computer Sciences of the University of California, Irvine. Before he was a Director of the Institute for Applied Information Technology (FIT) at the German National Research Center for Information Technology (GMD), and a Professor of Computer Science at the University of Essen, Germany. Dr Kobsa's research lies in the areas of user modeling and personalized systems (with applications in the areas of information environments, expert finders, and user interfaces for disabled and elderly people), privacy, and in information visualization. He is the editor of User Modeling and User-Adapted Interaction, editorial board member of the Springer Lecture Notes in Computer Science (LNCS), World-Wide Web, and Universal Access in the Information Society, and was the founding president of User Modeling Inc. Dr. Kobsa edited several books and authored numerous publications in the areas of user-adaptive systems, human-computer interaction and knowledge representation. He also co-founded a national workshop series and an international conference series in these areas. He received research awards from the Humboldt Foundation, Google, and several other organizations.

Mikhail Atallah: Professor of Computer Science, Purdue University

Privacy Technologies for Collaborative Computing

Abstract: Even though collaborative computing can yield substantial economic, social, and scientific benefits, there are serious impediments to fully achieving that potential. One of these is legal: Privacy laws and laws against collusive behavior (anti-trust) often forbid the disclosure of information, or strictly regulate the form and timing of that disclosure. But even when it is not illegal to share data, there is often a reluctance to share it, for fear of losing control over its subsequent dissemination and usage. We survey security technologies that mitigate this problem, and allow the data owner to enforce its approved purposes on the data used in collaborative computing. These include techniques for cooperatively computing answers without revealing any private data, even though the computed answers depend on all the participants' private data. They also include computational outsourcing, where computationally weak entities use computationally powerful entities to carry out intensive computing tasks without revealing to them either their inputs or the computed answers.

Mikhail Atallah

Biography: Mikhail Atallah holds the rank of Distinguished Professor of Computer Science at Purdue University. His research interests include information security, distributed computing, algorithms, and computational geometry. A Fellow of both the ACM and IEEE, he has served on the editorial boards of top journals, and on the program committees of top conferences and workshops. He was keynote and invited speaker at many national and international meetings, and a speaker eight times in the Distinguished Colloquium Series of top Computer Science Departments. He was selected in 1999 as one of the best teachers in the history of Purdue and included in a permanent wall display of Purdue's best teachers past and present. He is a co-founder of Arxan Technologies Inc.

Larry W. Korba: Principal Research Officer/Group Leader Information Security Group, Institute for Information Technology, National Research Council of Canada

Automating Privacy Compliance: A Technology Perspective

Abstract: Organizations of all types are besought by government bodies, regulators, partners, and their own operational or business demands to have and to uphold a set of privacy policies relevant to the personal data entrusted to them by customers. While creating a set of privacy policies is difficult enough, being able to demonstrate at any time how well it is upholding them is particularly demanding for organizations. Challenges range from discovering where important private data is located, to limiting different types of operations on that data, especially in an open computing environment. In this talk I will describe these challenges while exploring a set of core technologies that may be used to create automating privacy compliance systems.

Larry Korba

Biography: Larry Korba is the group leader of the Information Security Group in the Institute for Information Technology of the National Research Council of Canada, Ottawa, ON. As a Principal Research Officer, he is currently the research lead in a major R&D project involving the creation of automated compliance technology for privacy. Over the last 7 years he has led several research privacy technology projects involving collaborators in the European Union, Canada and Taiwan. He has published over 150 research papers in a variety of areas, and has given technical talks at many different venues. His research interests include network and application security, privacy protection, computer supported collaborative work and technologies for security intelligence.
