Short BIO

Seda Gurses is currently working on her PhD on "Multilateral Privacy Requirements in Social Networks" at the Department of Computer Science in K.U. Leuven. Previously, she has worked on the topics of privacy and security requirements analysis of Ubicomp scenarios, RFID based systems, e-health systems, open source software, feminist critique of computing, and e-learning at the Department of Information Systems, Humboldt University, Berlin.

Title of the presentation

Privacy Enhancing Tools: An Exploration of their Potentials and Limits

Abstract

One way to approach the topic of PETs is to distinguish privacy as we computer scientists construct it and privacy as individuals practice it in everyday life. Some of the main assumptions and ideas underlying PETs and privacy in computer science are:

• We live in a world without trust (or, a weaker form of the statement is: systems should require minimum trust).

• The way to protect privacy is for individuals to keep their information confidential.

• If information is to be revealed then this should be done in a controlled manner. Consent with a purpose and multiple pseudonyms that are unlinkable should be used and finality of data use should be guaranteed. Design should also address the security of the data and the accountability of the collectors.

I would like to talk about each of these points with examples from daily user information practices. When are the ideas listed above useful and where are their limits in these examples? Putting pets into context can help in both determining situations in which PETs are very much needed and in conceiving new pets, as well as legal or social measures, where they are limited.
