"Biometric authentication is the process of proof and authentication through the presentation by the user of his biometric image and by converting this image in accordance with a predetermined authentication protocol. Biometric authentication systems are authentication systems that use their biometric data to identify people.
Biometric systems consist of two parts: hardware and specialized software. Hardware includes biometric scanners and terminals. They fix a particular biometric parameter (fingerprint, iris, vein pattern on the palm or finger) and convert the obtained information into a digital model available to a computer. And software tools process this data, correlate with the database and make a decision who appeared before the scanner.
In order for the biometric system to be able to further identify the user, it must first register information about its identifiers. Commercial systems (unlike systems used by law enforcement and law enforcement agencies) do not store images of real identifiers, but their digital models. When the user re-accesses the system, a model of his ID is re-generated and compared to models already entered in the database.
Back in 2008, the possibility of face recognition was more a topic of scientific research, now it has become a real technology. Not only government agencies, but also commercial companies show interest in it. Market dynamics are very intense. According to research by International Biometric Group, in 2009 the global biometrics market amounted to $3.4 billion, according to their forecasts, by 2014 it will amount to $9 billion. Now, of the total biometrics market, 11.4% are occupied by face identification technologies, although four years ago analysts attributed this direction to the column "other."
