Office of Inspector General Enterprise Data System, July 10, 2015. The Department of Homeland Security (DHS) Office of Inspector General (OIG) maintains complaint and investigation related files on paper and in the electronic Enterprise Data System (EDS). EDS is the official OIG electronic case management system. OIG uses EDS to manage information relating to complaints and investigations of alleged criminal, civil, or administrative violations by DHS employees, contractors, grantees, beneficiaries, and other individuals and entities associated with DHS, and manage investigations born from those complaints to facilitate the tracking of resources used in investigative activities. This PIA update is necessary because (1) the PIA name has been changed from Investigative Records System (IRS) to Enterprise Data System; and (2) EDS has been modernized and now includes the capacity to retain biometric information for investigative purposes and OIG employee work performance history information.  The current and previous versions of this PIA are listed below.
