What is biometric authentication?
Biometric authentication is a process of verifying user identity that involves biological input or the scanning or analysis of a part of the body.
Biometric authentication methods are used to protect many different types of systems - from logical systems enabled by hardware access points to physical systems protected by physical barriers, such as secure facilities and protected research sites.
Security professionals often distinguish biometric authentication from other types of authentication, such as: For example, knowledge-based authentication, which uses passwords or other information unique to a particular user. Another broad type is known as 'property-based authentication', in which authentication relies on an object held by the user, such as a key or card.
Biometric authentication is widely known as the most effective type of authentication because it is extremely difficult to transfer biological material or functions from one user to another. However, the traditional cost of biometric authentication has made it impossible for many projects. New technologies are making biometric authentication more realistic for a number of different implementations.
The most common and advanced types of biometric authentication include face scanning. Face scanning tools can now identify people and be used for various types of security and authentication. Fingerprint-based authentication is also common. Some types of biometric authentication focus on specific functions, such as: B. Eyes, while others use more comprehensive body scan models.
