I Introduction

Operation Principle

Fingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the

matching can be 1:1 or 1:N).

When enrolling, user needs to enter the finger two times. The system will process the two time

finger images, generate a template of the finger based on processing results and store the template.

When matching, user enters the finger through optical sensor and system will generate a template

of the finger and compare it with templates of the finger library. For 1:1 matching, system will

compare the live finger with specific template designated in the Module; for 1:N matching, or

searching, system will search the whole finger library for the matching finger. In both

circumstances, system will return the matching result, success or failure.
