Alessandro Acquisti is an Associate Professor of Information Systems and Public Policy at the Heinz College, Carnegie Mellon University (CMU) and a member of Carnegie Mellon CyLab.
Acquisti's research focuses on the economics of privacy. His studies have spearheaded the application of behavioral economics to the analysis of privacy and information, security decision making and the analysis of privacy risks and disclosure behavior in online social networks.
In this TED Talk Alessandro Acquisti explains how and why the line between public and private, both online and in real life, has blurred in the past decade and might even be erased in the (near) future. With his thought-provoking, slightly chilling talk, he shares details of recent and ongoing research, including a project that shows how easy it is to match a photograph of a stranger with their sensitive personal information.
What motivates you to share your activities and personal information online? After watching this presentation ask yourself how and why you (still) use the plethora of social media. The preservation of your privacy may very well depend on it.
