101 of biometric enrolment

In the digital identity domain, Biometric Enrolment is the process of using a biometric equipment to collect an individual’s biometric information for the purpose of using the captured information in future to recognize, verify or identify that individual. The person whose biometric information is so captured is known as the enrollee.

Biometric enrolment is a one-off operation and is not the same thing as biometric verification, recognition, or identification which can be undertaken as often as necessary. The initial enrolment process captures the individual’s biometric information, while future verification uses previously-stored information to verify or confirm his/her identity.

In practice, the biometric enrolment process involves the use of a specific biometric system to capture the biometric image in one of various scenarios illustrated in the three figures below.
Figure 1: Fingerprint captured using fingerprint scanners.

 Figure 2: Facial image captured using facial recognition system.

Figure 3: Iris pattern captured using appropriate eye biometrics equipment.

Each biometric equipment contains a scanner which obtains the actual biometric image from the enrollee. The processed image is changed into electronic form and stored on the equipment. Nearly all biometric equipment have the capacity to send the captured information to a remote database for security and centralized access.
