How does fingerprinting work

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
