Biometric Characteristics

Fingerprint Biometrics

How does fingerprint biometrics work?

Fingerprint biometrics work by capturing the fingerprint image with sufficient detail with either optical, silicon, or ultrasound. The two main ways to recognize fingerprint are:

• Minutia matching: it compares specific details within the fingerprint ridges. It locates the minutia points, together with their relative positions to each other and their directions. It then compares the extracted minutia points to the registered template
• Pattern matching: it compares the overall characteristics of the fingerprints, not only individual points. The data captured might include ridge thickness, curvature, or density.  Small sections of the fingerprint and their relative distances are extracted
  

How is this technology being used?

Airport check-in:

• cut the consumption of time
• decrease identity theft
• better customer service

• more secure
• don't have to worry about stolen, forgotten passwords
• a person places their finger onto the device then with the fingerprint scanning software, once it's matched, the system will be unlocked
  

• used in At least four counties in California, including L.A

• cheapest and best means to prove the identity of a criminal
• accurate

• Enter the password to access fingerprint scanning, then put your finger on the scanner
• the system captures the fingerprint and runs through the database, if a match is found, the door will be unlocked
