EPIC has filed a Freedom of Information Act lawsuit against the FBI to obtain documents about "Next Generation Identification", a massive database with biometric identifiers on millions of Americans. The EPIC lawsuit follows the FBI's failure to respond to EPIC's earlier FOIA requests for technical specifications and contracts. According to EPIC's complaint, "When completed, the NGI system will be the largest biometric database in the world." NGI aggregates fingerprints, DNA profiles, iris scans, palm prints, voice identification profiles, photographs, and other identifying information. The FBI will use facial recognition to match images in the database against facial images obtained from CCTV and elsewhere. For more information, see EPIC v. FBI - Next Generation Identification, EPIC: Biometric Identifiers and EPIC: Face Recognition.
