EFF: “As noted in our first post, EFF recently received new documents via our FOIA lawsuit on social network surveillance, filed with the help of UC Berkeley’s Samuelson Clinic, that reveal two ways the government has been tracking people online: Citizenship and Immigration’s surveillance of social networks to investigate citizenship petitions and the DHS’s use of a “Social Networking Monitoring Center” to collect and analyze online public communication during President Obama’s inauguration. This is the second of two posts describing these documents and some of their implications. In addition to learning about surveillance of citizenship petitioners, EFF also learned that leading up to President Obama’s January 2009 inauguration, DHS established a Social Networking Monitoring Center (SNMC) to monitor social networking sites for “items of interest.” In a set of slides [PDF] outlining the effort, DHS discusses both the massive collection and use of social network information as well as the privacy principles it sought to employ when doing so.”
