context_page_description: In order to identify a person, a security system has to compare personal characteristics with a database. A scan of a person's iris, fingerprint, face, or other distinguishing feature is made and a series of biometric points are drawn at key locations in the scan. In the case of a facial scan, biometric points might be placed at the tip of each ear lobe and in the corners of both eyes, for example. Measurements taken between all the points of a scan are compiled and result in a numerical "score", unique for every individual, yet which can quickly and easily be compared to the previously compiled scores of all the facial scans in the database to determine if there is a match.
context_section_description: To be able to recognize a person by biometric characteristics and derived biometric features, a learning phase must first take place.
   The procedure is called enrolment and comprises the creation of an enrolment data record of the biometric data subject (the person to be enrolled) and its storage in a biometric enrolment database. The enrolment data record comprises one or multiple biometric references and arbitrary non-biometric data such as a name or a personnel number.
