LET ME SEE YOUR FINGERS.
The various biometric procedures differ substantially in the error rate / recognition rate. With a market share of over 60%, fingerprint identification is the most widely used biometric identification technology. Smartphones with fingerprint sensors and systems for border security contribute significantly to market penetration.
Characteristic points such as line ends and branches of the fingerprint (so-called minutiae) are recorded and evaluated by a scanner or sensor. To minimize the recognition time, access systems do not store and evaluate the complete image (photo) of the fingerprint, but only characteristic features, i.e. the template.
During verification, the captured data is compared with reference data on a chip card or in an access terminal. During identification, the comparison is made with all reference data stored on a database, which of course can take longer than verification.
The acceptance of fingerprint identification has increased considerably, not least due to the integration of fingerprint sensors in keyboards, mice or laptops. The security against counterfeiting is of course far below that of technologies such as iris recognition or vein recognition.
