EPIC has filed a Freedom of information Act lawsuit against the Department of Homeland Security to force disclosure of the details of the agency's social network monitoring program. In news reports and a Federal Register notice, the DHS has stated that it will routinely monitor the public postings of users on Twitter and Facebook. The agency plans to create fictitious user accounts and scan posts of users for key terms. User data will be stored for five years and shared with other government agencies.The legal authority for the DHS program remains unclear. EPIC filed the lawsuit after the DHS failed to reply to an April 2011 FOIA request. For more information, see EPIC: Social Networking Privacy.
