As can be evidenced, biometrics devices have several uses and this has led many to access them. Regardless of the categories physical or behavioral, biometric systems are powerful recognition tools, which can validate or establish the identity of people very easily, in addition to speed and accuracy. The Nanny Cameras are important there.
Classification of biometrics devices
In behavioral biometrics devices:
As for behavioral biometrics devices, these are those that analyze entrenched human characteristics and that hardly change over time.
Example of behavioral biometrics:
A computer security system, which uses signature recognition, is a behavioral biometrics device. As the basic characteristics of a person’s signature do not change, the system recognizes the entry entered as an authentic or a forged one. According to recent studies, these systems are mainly used to verify the identity of a person.
In physical biometrics devices:
On the side of physical biometrics devices, they are based on qualities that can be a bit more tangible. In addition, there are physical qualities that do not change over time and this allows physical biometrics devices to be used for identification issues. A fingerprint scanner, in access control or on a computer, is a physical biometrics system,
Example of physical biometrics:
Currently, biometric devices are mainly used in security applications. Thus, buildings, businesses, laboratories, machinery, important data and others, can be protected by biometrics. In the same way, biometric devices can be used to monitor attendance and arrival and departure times in the workplace. In fact, in some places, traditional management systems have been replaced by biometric clocks, which allow keeping a better record of the assistance and schedules of employees in a particular place.
Biometrics Mechanisms
Before falling into the most popular devices it is important to describe what they are and what biometrics mechanisms are for. First, these are mechanisms that examine a personal quality with the purpose of confirming or establishing the identity of people. Among the many qualities that biometrics solutions can examine are fingerprints, retina, iris, face and veins and for this reason biometric identification or validation schemes can have various shapes and dimensions. Being able to validate or establish someone’s identity is useful in many cases, especially if these processes can be done in a short time and with remarkable accuracy. Today’s biometrics mechanisms are characterized by making checks 1 to 1 in the case of validation or 1 to many in the case of establishment, in very short times and with impressive accuracy. In this way, the manufacturers of security systems have found in the biometric devices one of the best options of the moment.
Device Examples
The fingerprint, iris, retina, etc. readers, apart from being precise and fast today, are also more compact and this allows them to be used virtually anywhere. As an example of this, we can talk about the portable fingerprint readers that police forces use to verify if a person has a criminal record.
The possibility of taking a scanner of biometric qualities to any part has been decisive for the creation of very sophisticated security mechanisms, in which the identity of each person entering or leaving a certain area is verified. These mechanisms have been taking a lot of strength over time and so it is very common to replace traditional security mechanisms with scanners of some personal quality.
