Milton Mueller will be a keynote speaker at the upcoming Privacy in Social Network Sites Conference to be held October 23-24, 2008 at Delft University of Technology (TU Delft). The program is available here. Recently, Social Network Sites (SNS) have been used to support the American presidential campaigns and to smuggle photos of the natural disaster out of the country of Myanmar. However, the centralized collection, processing and dissemination of such as large amount of identity-relevant information has lead to increased disclosure of sensitive information, identity theft and physical and mental harm. This calls for a thorough consideration of why we should restrain access to our identity-relevant information and how a concept of ‘privacy’ in Social Network Sites could be developed. This conference will deal with a wide range of topics that relate to Social Network Sites, varying from moral reasons to protect privacy to concrete ways to protect users’ privacy.
