Biometric Definitions
Enrollment
is the operation of scanning a fingerprint, determining the
quality of the fingerprint scan, and storing a good template together with
associated data in the FPU memory.
The following enrollment methods are available.
One time
– Enrolls a scanned fingerprint to a fingerprint template. Supported by all FPU units.
Two times
– Scans the fingerprint twice. The two images are compared to each other and verified. If the
fingerprint images do not match the user is rejected. If they match the better quality fingerprint is enrolled
in the template. Supported by FPU- S units only.
Two templates
– Scans the user finger twice and saves the each fingerprint scan as a template. The user has
two templates stored. Then, each time the user is verified, the module can decide whether to replace the
existing template with a new one. This update reflects the dynamic changes in the skin of the user's finger.
Supported by FPU- S units only.
