The FBI is working to keep information contained in a key biometric database private and unavailable, even to people whose information is contained in the records.
The database is known as the Next Generation Identification System, and it is an amalgamation of biometric records accumulated from people who have been through one of a number of biometric collection processes. That could include convicted criminals, anyone who has submitted records to employers, and many other people. The NGIS also has information from agencies outside of the FBI, including foreign law enforcement agencies and governments. Because of the nature of the records, the FBI is asking the federal government to exempt the database from the Privacy Act, making the records inaccessible through information requests.
The bureau says in a proposal to exempt the database from disclosure that the NGIS should be exempt from the Privacy Act for a number of reasons, including the possibility that providing access could compromise sensitive law enforcement information, disclose information which would constitute an unwarranted invasion of another’s personal privacy; reveal a sensitive investigative technique; could provide information that would allow a subject to avoid detection or apprehension; or constitute a potential danger to the health or safety of law enforcement personnel, confidential sources, and witnesses
