In accordance with the Secretary of Homeland Security’s recent announcement on the Department’s use of artificial intelligence (AI), the DHS Office of the Chief Information Officer, in coordination with the Science and Technology Directorate, Privacy Office, Office for Civil Rights and Civil Liberties, and Office of the General Counsel, is leading the Department’s efforts to ensure responsible use of AI while fulfilling the Department’s mission and supporting its workforce. As part of this effort, the DHS Office of the Chief Information Officer is working to advance specific mission applications of AI across the Department and address ways in which the workforce may use conditionally approved commercially available generative AI (Gen AI) tools (i.e., tools not procured for use for specific Department missions) for certain aspects of their work. “Gen AI” is the class of AI models that emulate the structure and characteristics of input data to generate novel synthetic content (i.e., outputs). This can include images, videos, audio, text, code, and other types of digital content. This Privacy Impact Assessment (PIA) analyzes the Department’s use of conditionally approved Gen AI tools.
