The FBI has been building a massive biometric database for the last eight years. The Next Generation Identification System (NGIS) starts with millions of photos of criminals (and non-criminals) and builds from there. Palm prints, fingerprints, iris scans, tattoos and biographies are all part of the mix. Despite having promised to deliver a Privacy Impact Assessment of the database back in 2012, the FBI`s system went livetowards the end of 2014 without one. That`s a big problem, considering the database`s blend of guilty/innocent Americans, along with its troublesome error rate. The FBI obviously hopes the false positive rate will continue to decline as tech capabilities improve, but any qualms about bogus hits have been placed on the back burner while the agency dumps every piece of data it can find into the database.
