A privacy watchdog has filed a lawsuit contending the Federal Bureau of Investigation has failed to provide requested technical information about a biometric identification database expected to be the largest in the world.

The Electronic Privacy Information Center (EPIC), a nonprofit organization based in Washington, alleges the FBI failed to disclose documents after it filed two Freedom of Information Act (FOIA) requests in September 2012.

EPIC sought information on the FBI’s “Next Generation Identification” program, which will amass biometric information on mostly U.S. citizens from local, state and federal law enforcement agencies, including palm prints and iris scans. New York City’s police department began collecting iris scans in 2010 of people who were arrested.
