PEP05: UM05 WORKSHOP ON PRIVACY-ENHANCED PERSONALIZATION

Personalizing people's interaction with computer systems entails gathering considerable amounts of data about them. As numerous recent surveys have consistently demonstrated, computer users are very concerned about their privacy. Moreover, the collection of personal data is also subject to legal regulations in many countries and states. Such regulations impact a number of frequently employed personalization methods. This workshop will explore the potential of research on "privacy-enhanced personalization," which aims at reconciling the goals and methods of user modeling and personalization with privacy constraints imposed by individual preferences, conventions and laws. It will look at, e.g., the following questions:

- How much personal data do individual personalization methods really need? Can we find out in advance or in hindsight what types of data contribute to reasonably successful personalization in a specific application domain, and restrict data collection to these types of data? - Is client-side personalization a possible answer to privacy concerns and legal restrictions? What technical, legal and business obstacles will have to be overcome? - In what way should the user be involved in privacy decisions? What does appropriate notice and choice look like, and what rights must and should be granted? - Will we need trusted third parties, and what services will we need them to provide? - How much can we benefit from anonymity or pseudonymity infrastructures, and are there limits that should be observed? - Are distributed user models an answer or a problem from a privacy perspective? - Does personalization in a mobile context pose additional challenges? How can they be overcome? - Do mobile user models pose additional privacy problems? - How can multi-user personalized systems cater to the privacy constraints of each individual user? - What should an ideal legal framework look like from the perspective of privacy-enhanced personalization? - Are special provisions necessary in the case of people with disabilities and student-adaptive educational systems?

The one-day workshop will be held during the Tenth International Conference on User Modeling in Edinburgh, Scotland (http://gate.ac.uk/conferences/um2005/um05.html). It is intended for researchers and practitioners both in the domain of personalization systems and in the area of privacy and security who will make active contributions to the workshop. Two types of contributions are invited: - Papers describing (ongoing) work on one or more of the topics for the workshop (8 page maximum) - Position statements regarding one or more of the topics for the workshop (2 page maximum)

Both papers and position statements should be prepared according to the UM05 Instructions for Authors (http://www.springeronline.com/sgw/cda/frontpage/0,11855,5-164-2-72376 -0,00.html) and be sent to kobsa@uci.edu and lorrie@cs.cmu.edu by March 7, 2005. Each paper and position statement will be reviewed by at least two reviewers. Accepted contributions will be published in the workshop proceedings and will be available on the Web before the workshop. Depending on the quality of the accepted papers, a post-conference book publication is also envisaged.
