Discrete Facial Recognition System
We can immediately compare that photo against one or more face recognition databases to attempt an identification.
Facial recognition can be used in airports, at border crossings, and during events such as the Olympic Games. Facial recognition may also be used in private spaces like stores and sports stadiums, but different rules may apply to private sector face recognition.
The federal government has several facial recognition systems, but the database most relevant for military & law enforcement applications is FBI’s Next Generation Identification database which contains more than 30-million face recognition records. FBI allows state and local agencies “lights out” access to this database, which means no human at the federal level checks up on the individual searches. In turn, states allow FBI access to their own criminal face recognition databases.
