A biometric system uses an automated device to measure physical or behavioral characteristics of an individual to identify that person.
Fingerprint, face, iris, vein etc are used to measure physical characteristics while voice, signature etc are used to measure behavioral characteristics.
(Face recognition, fingerprint recognition, iris recognition, unmanned surveillance, access control, personal authentification, immigration control, code technology, database).
Individuals are verified utilizing database storing different aspects of their facial features. It is commonly used since it uses non-contact camera method for authentification.
The derma underneath the outer layer of skin, which never changes unless it is damaged, has commonly been used for personal identification for a long time. It requires the comparison of several features of fingerprint including ridges and minutia points with the saved data.
Iris recognition is an improved security system in terms of data accuracy, safety, user-convenience and processing speed, and it uses an individual’s eyes, whose complex random patterns are unique. The iris develops into a unique pattern within 1-2 years since birth, which never changes in one’s whole life. Since it uses the non-contact method where the iris pattern is recognized by auto-focus camera at a distance of 8-25m, it does not cause resistance to use, and it can identify a person within 2 seconds.
This was introduced from the fact that each individual has unique pronunciation, intonation and speaking habits. Voice transmitted through the phone or microphone is analyzed to search the nearest match. One of the advantages over other biometrics is that individuals can be identified at remote places using the phone.
