What are biometric data?

Biometric data relates to records used to identify people, such as fingerprints. Biometrics is a name given by different methods of capturing, storage and use of biometric data. Two main use of biometry include individual identification for the purposes of controlling access and various applications for solving and preventing crime.

characteristics that are used to authenticate biometry are often classified into two main categories, physiological and behavioral. Physiological biometric data relate to the physical aspects of human body. These include items such as fingerprints, retina scanning and facial scanning. Behavioral biometric data, sometimes called behaviometry, include signatures, manuscript analysis and voice pattern recognition. The data item should be universal, tklobouk means that all people should have characteristics. It should be unique for an individual to be definitely recognized. It should be permanent, that is,That it should be a characteristic that does not change significantly as one ages. For example, using a blood sample for DNA analysis is significantly more invasive and more expensive than the use of fingerprints. In addition, concerns about the efficiency and accuracy of the technology used to measure biometric data may impact the type of data that are selected for a specific application.

Biometric devices tend to function one of two main ways, verification or identification. In verification mode, biometric technologies perform a single comparison of the presented data with the template previously stored. An example is the fingerprint scanner on a personal computer or electronic safe. The biometric database is used in identification mode. Then the individual data item is captured and the system tries to customize this piece of data with any of the existing items defined in the database. An example of identification biometry is the databaseof the fingerprints of the fingers of well -known criminals.

There are some concerns surrounding the area of ​​biometric technologies and extensive storage of biometric data. Biometry opponents may cite personal data protection, for example, that data could later be used for purposes that the individual disagreed with, or even that information could be potentially stolen. Another problem that is sometimes caused is concerned that biometric data trades could be abused to distinguish certain branches of the population.
