Face recognition database is a record of identified images of human faces taken by a face recognition device. When a face recognition device scans a human face, it then matches the identified image against the enrolled image that is stored in face recognition database. Sometimes face recognition database gets larger and needs additional space to store other identified images.
In most law enforcement agencies, face recognition database is kept in a secured location to prevent it from any unauthorized access, and so that it can only be accessed by security authorities. Face recognition database can store facial measurements and information for one year, or even for longer period of time.
