"The Office of Operations Coordination and Planning (OPS), in cooperation with the Science and Technology Directorate (S&T) is publishing this PIA to reflect a planned research project regarding Suspicious Activity Reports (SARs). The Operations Coordination and Planning Directorate will host a stand-alone system designed to analyze Suspicious Activity Report data taken from several Department of Homeland Security (DHS) components. OPS has conducted this PIA because SARs occasionally contain personally identifiable information (PII) and because it is physically hosting the project in addition to contributing SARS data. Several components within DHS collect and use Suspicious Activity Reports (SARs) in the execution of their mission and operational duties. SARs are defined by the Program Manager-Information Sharing Environment (PM-ISE) as 'observed behavior that may be indicative of intelligence gathering or pre-operational planning, related to terrorism, criminal, or other illicit intention.' All SARs are centered on activities, meaning that an event or action has occurred that has aroused some degree of suspicion. DHS components collect SARs which are stored and used as they are received during the course of daily operations in law enforcement, maritime, intelligence, and other sectors in which DHS has a presence. While each DHS component will collect and analyze SARs data as it has done in the past, until recently DHS has not had a unified method to analyze SARs data across DHS components."
