In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes.
Authentication by biometric verification is becoming increasingly common in corporate and public security systems and consumer electronics.
Biometric devices, such as finger scanners, consist of:
- A reader or scanning device
- Software that converts the scanned information into digital form and compares match points
- A database that stores the biometric data for comparison
