The Digital Defense Content Provenance Act of 2023 requires the Department of Defense to establish an educational course and launch a pilot program focused on authenticating digital media and detecting manipulated content. Within one year of enactment, the Defense Media Activity must create a course at the Defense Information School teaching military public affairs and records management specialists how to verify the authenticity of photos and videos using industry technical standards, and how to recognize threats posed by deepfakes and other digitally altered content. Simultaneously, the department must begin a pilot program by 2024 to test methods for authenticating Department photos and videos released publicly, with the pilot running through January 2027 and a progress report due by January 2026. The bill affects Department of Defense personnel involved in media, communications, and records management, as well as the military's public information distribution efforts. No specific funding amount is mentioned in the legislation, though the Director may request additional resources to implement these initiatives.
