Enrollment
New users are entered into the system through the process of “enrollment”. This
procedure scans the users fingerprint and produces a fingerprint template, a
collection of data that is stored in memory on the Veriprox. This includes:
•
User
Name
•
User Finger Identifier
•
Template
Security
Threshold
•
Template
ID
•
Template
Index
Number
•

Templates
Every template on a Veriprox unit is unique. Each time a fingerprint is enrolled a
new template is generated using the number from the proximity card as the
Template ID number. The system automatically increments and assigns an index
value to each template.
Figure 7: Template ID Numbers
1. The ID number of the card to which the template is being assigned.
2. The index number of the template; this is assigned automatically by the
software. Index numbers differentiate between fingerprints assigned to
the same Template ID number (i.e., card number).
Please see Appendix A – Quality and Content on page 48 for a technical
description of what constitutes a good enrollment. A quality enrollment will ensure
peak performance from the Veriprox fingerprint recognition algorithm.
