What is biometric identification?
Biometric identification is a process by which a person can be identified according to his characteristics. For this purpose, data on defining characteristics, such as points where the ridges of the division or ends of the fingerprints are usually written and stored in the database. After the person wishes to be identified, the characteristic is scanned so that the computer can compare it to the data already stored in the database. The use of biometric identification is a safer method of identifying a person because the characteristic is part of that person. This means that it cannot be easily shared, traded or stolen by another. Physiological biometry is related to human physical features and biometrics of behavior have to do with things that can change with the environment. For example, fingerprint, physiological characteristics, usually does not change with the exception of an accident or illness, but signature, behavior characteristics, may change how one ages. Examples of physiological biometrics include fingerprints, scanning withItem and hand scanning. Behavioral biometry includes verification of signatures and voice recognition.
Fingerprints is perhaps the best known form of biometric identification. It is used in the police department to identify suspects and is used as computer login information. If you want to use fingerprints to identify a person, the printing of a person must first be in the database. If not, the match cannot be returned. The method that is commonly used in fingerprint biometry corresponds to points for human records, part of the fingerprint, where it ends or split the ridges.
Equipment can also use the people of a person for biometric identification. This is called retinal scanning. The retina scan uses the nuns caused by blood vessels in the eye. Another method that uses an eye for biometric match is the scanning of the iris. When scanning Iris it is taken a picture of an eye that can then be rSkays compared to the previous image taken and stored in the database.
In addition to physiological data, biometric identification can also be performed by behavior methods. When enrolled, a behavioral characteristic such as a voice is captured and stored in the device. The voice can then be compared when a person speaks back to the device. Toys of some children - such as the diaries of young girls - use this technology. The disadvantage of this type of identification is that behavior characteristics may change during the day and may result in a person who has a cold locked from their secure devices if they use voice recognition technology.
