Colloquium - Lipford

Personal Privacy Management
University of North Carolina at Charlotte
4/21/2011
3:30pm-4:30pm

A variety of online and mobile applications allow people to post and share photos and documents, personal and contact information, relationships with people and organizations, and location and activities. The goal of all of these applications is to allow people to share useful information with each other for social benefits, and with organizations for customized and useful services. Yet, users are required to act as administrators for all of their own data, managing who can access which pieces of information in which circumstances. On one hand, users can seem oblivious to their privacy, doing little to protect their personal data. On the other hand, there has been much media coverage and even consumer backlash over privacy issues. In this talk, I will present the results of several projects aimed at understanding and addressing the privacy needs of users. Our research demonstrates that users do have privacy concerns and problems, and could benefit from greater awareness and control over the sharing of their information. We have designed several new access control mechanisms and interfaces to address these problems, aimed at maintaining the benefits of information sharing while reducing the risks information disclosures.
