What is Biometric Authentication?

Biometric authentication is a security process based on the technology of recognizing a person's identity through their biological characteristics. The uniqueness of these characteristics allows to confirm whether a person is the same user they claim to be. The person's biometric data is loaded into a database and is considered the reference data. Then, when requesting access to an information resource, the biometric authentication system takes the user's entered data and compares it with the reference data stored in the database. If the data matches, the authentication is considered successful, confirmed, and the user is granted access to the resource.

Biometric authentication can be used to control both physical access to objects (buildings or individual rooms) and to grant access to various information resources (systems, applications, databases, etc.).

Biometric authentication improves security because it is difficult to forge a person's biological parameters. However, it is also very convenient because it is impossible to forget or lose your biometrics.
