Privacy Impact Assessments

Definition of a Privacy Impact Assessment (PIA)

Privacy Impact Assessment (PIA) describes a process used to evaluate the collection of personal data in information systems. The objective of a PIA is to determine if collected personal information data is necessary and relevant.

To accomplish this objective, a PIA is used to identify and address information privacy when planning, developing, implementing, and operating individual agency information management systems and integrated information systems. A PIA will assess "security and privacy risks" associated with operating information systems that collect, access, use, or disseminate personal information.
