Biometric modality that matches images of finger tips.

In forensic science, fingerprint identification is the analytical process of comparing two instances of friction ridge skin impressions from human fingers for identity verification. However, this technology may also work on almost any other region of skin on the human body.

In cybersecurity applications, a fingerprinting algorithm is a procedure that maps an arbitrarily large data item (such as a computer file) to a much shorter bit string, its fingerprint, which uniquely identifies the original data for all practical purposes. This is similar in the real-world case just as human fingerprints uniquely identify people. This digital fingerprint may be used for data deduplication purposes and data integrity verification.

A digital fingerprint may also refer to the pieces of information that are created by an individual during the use of some system. This can include cookies, inputs, selected options, etc. which can all be used to track a user's behavior and record any events.
