Biometrics: Fingerprinting

By SherifElzanie


Usage of Fingerprinting

  • Fingerprinting is the most commonly used biometric identification scheme

    • Reasons: Cheapest, fastest and most reliable.

    • Fingerprinting has about 60% of the biometric world market

  • Fingerprinting is used in criminal investigations, laptops and has been recently integrated into airports such as Heathrow.


Fingerprinting


How does Fingerprinting Work?

  • Fingerprinting basically works by identifying finger patterns that are unique to an individual.

  • These unique characteristics are usually composed of ridges and patterns imbedded in each person’s finger.

  • These unique characteristics are formerly called minutiae and are found on fingertips


How does Fingerprinting work? (cont’d)

  • The exact method differs in each type of technology

  • The most common methods are optical scanning and capacitance scanning.

    • When a fingerprint is passed over the scanner a gray scale image is captured

    • Computer software identifies key minutiae points

    • They are converted into a unique digital representation known as a template

    • The template is compared and matched to all other fingerprints in the database
