To use biometric identification, first it is necessary to register the biometric characteristics of people in a secure database, then, in the identification process, the biometric information of a person who wants to be verified or identified is compared with the samples stored in the database.
There are several technologies used in biometric identification, such as:
- Fingerprinting: The unique characteristics of fingerprints are used to identify a person. Images of the fingerprints are taken and algorithms are used to compare them with the stored ones.
- Iris and retina: Identification based on the iris or retina of the eye is used. These methods require the use of specialized cameras to capture images of the eye and compare them with those in the database.
- Face recognition: Facial pattern recognition is used to identify a person. Algorithms are used to analyze unique facial features, such as the shape of the face, eyes, nose, mouth, etc.
- Voice Recognition: Voice recognition is used to identify a person. Voice prints are recorded and used to compare them with stored samples.
Biometric identification is used in a wide range of areas, such as security, access control, device unlocking, biometric passports, attendance management, and many others. This technology has become increasingly popular and is considered a very accurate and secure way to establish a person's identity.
