PEP06: CHI 2006 WORKSHOP ON PRIVACY-ENHANCED PERSONALIZATION
Workshop website: http://www.isr.uci.edu/pep06
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.
The workshop is intended for researchers and practitioners in the
field of personalization systems and in the area of privacy and
security, and specifically for people who are working at the
intersection of both. The workshop participants will look at Privacy-
Enhanced Personalization from an interdisciplinary perspective,
including the areas of Human-Computer Interaction, Management
Information Systems, and Economics. Participation from industry is
strongly encouraged since the results will have direct implications
on existing websites. It will discuss, e.g., the following questions:
1. 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?
2. What are motivators for people to disclose personal information,
and what motivators are present in what kinds of personalization? How
can the presence of such motivating factors be conveyed to users?
3. If discrepancies between users' stated privacy attitudes and
observed privacy behavior are rampant, what methods should be chosen
under what circumstances to conduct empirical research on privacy?
4. If privacy decisions are impaired by limited information and
bounded rationality, how can we help people make better choices?
5. In this context, what is the status of "privacy preferences"?
6. How much can we benefit from anonymity or pseudonymity
infrastructures and trusted third parties, and are there limits that
should be observed?
7. Are distributed user models an answer or a problem from a
8. Does personalization in mobile and ubiquitous computing contexts
pose additional challenges? How can they be overcome?
9. Is client-side personalization a possible answer to privacy
concerns and legal restrictions? What technical, legal and business
obstacles will have to be overcome?
10. What should an ideal legal framework look like from the
perspective of privacy-enhanced personalization?
The two-day workshop will be held on April 22 and 23 during the CHI
2006 conference (http://www.chi2006.org/) in Montréal, Canada. 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)
Submissions should be sent to [log in to unmask], [log in to unmask] and

by at least two reviewers. Notification about acceptance or rejection
will be sent out by Jan. 27. Accepted contributions will be published
in the workshop proceedings and will be available on the Web before
the workshop. Concrete steps for a post-conference publication have
already been taken (namely a special magazine or journal issue or a
book publication, depending on the nature and quality of the
