What Is Fingerprint Comparison?
The fingerprint comparison technology is a technology for comparing and comparing fingerprints in two or more fingerprint images.

- The fingerprint comparison technology is a technology for comparing and comparing fingerprints in two or more fingerprint images.
- The stripe line that bulges upward in the fingerprint is called the "bulge line". Part of the uplift line will show fractures and bifurcations. The break is called the "end point" and the bifurcation is called the "branch point". The above two points are collectively called "characteristic points". The center of a typical fingerprint contains about 50 feature points. The "position" and "direction" obtained from these feature points have become the basic data for comparison.
- Just comparing the position and direction of the feature points, chances of coincidence still happen by chance. In order to solve this problem, NEC has developed a method of identifying "connected relationships" to enhance the accuracy of fingerprint identification. The so-called "connected relationship" refers to the number of "bumps" across the feature points and other feature points. (NEC has obtained a patent)
- NEC's products use a combination of "feature points and connected relationships" for fingerprint comparison. As a result, better alignment accuracy is obtained.
- PID (Positive Identification) `` 1: N comparison '' and `` 1: 1 comparison ''
- 1: N comparison uses "input fingerprint" to compare all fingerprint data that has been registered.
- Find consistent fingerprints.
- 1: 1 comparison Among the registered fingerprints, you must first enter the "ID number".
- Only the personal fingerprint comparison method can be performed.
- NEC's fingerprint recognition system does not need to enter an ID number during comparison. This "1 N fingerprint comparison method" requires only a simple tap of the finger during the comparison. Can improve user convenience and safety [1] .
