Privacy-Conscious Information Sharing in Online Social Media SitesDr. Anna Squicciarini from Penn State's College of Information Sciences & Technology will present the following Computer Science seminar.

: In this seminar, I will present my recent work in Access Control and Privacy issues for Social Network sites. I will discuss security implications related to disclosure of inappropriate data across Social Networks, and use as a case study the problem of digital images distribution and misuse. Two specific issues will be discussed: first, how to assess co-ownership, if multiple users appear to be stakeholders of the same image. Second, we will look into the problem of image control within and across social network sites. I will discuss our approach to these issues, which draw from game theory and algorithmic results. I will provide an overview of the deployed prototype and provide some interesting insights obtained from performance and user studies. Our studies provided us with interesting findings, in terms of users' perception of privacy and protection from security threats. I will conclude with highlighting interesting issues that represent open problems and with insights on new lines of research for this work.

Biography: Dr. Anna Squicciarini joined Penn State's College of Information Sciences and Technology as an assistant professor in January 2008. Squicciarini's main research interests include trust negotiations, privacy, digital identity management, and access control for grid computing systems. Currently, she is investigating security issues in the context of social networks and is developing trust negotiation protocols in peer-to-peer platforms. Squicciarini earned her Ph.D. in Computer Science from the University of Milan, Italy, in March 2006. Squicciarini is the author or co-author of more than 60 conference papers and journal articles. Currently, she is co-author of a book on Web services security published by Springer. She serves as a program committee member for many relevant security and privacy conferences, including ACM Sacmat 2013, Privacy Enhancing Technologies 2012, and IEEE International Conference on Distributed Systems 2013.
