Such devices are equipped with an appropriate scanning field, to which you should put the pad of any finger of your right or left hand. The system takes a photo but it does not have to be a simple photo of such a pad and then analyzes the arrangement of characteristic points and other finger identification features. The result of this analysis is a block of data that is stored. The Biometric Access Control Systems are perfect in this case now.
Fingerprint readers
Importantly, as a rule, the photo of the fingertip is not remembered. What’s more, it is not possible to restore such a photo from a saved data block. Fingerprint readers are great for verifying a person i.e. confirming the identity of a known person. In practice, it usually happens in such a way that a person gives a certain code identifying them before scanning their fingerprints. This compares the data block read from the fingerprint with one data block located in the reader’s memory or in the database.
There are some technical limitations associated with the fingerprints themselves that make the identification of a person i.e. determining who the given fingerprints belong to without giving any hint is a much more complex process. In practice, this means that this process takes longer and therefore you must use readers with the appropriate high computing power.
Applications of fingerprint
The most popular applications of fingerprint readers are physical access control or work time recording systems and logical access control to workstations, operating systems or individual applications installed on computers. The undoubted advantage of using fingerprint readers is the lack of necessity to remember often long and complex passwords or pins, and no need to wear additional identifiers cards, key fobs.
Systems based on fingerprint readers due to the technology used and affordability is the most frequently chosen biometric solutions by customers. Biometrics has been used widely today because it is an efficient security mechanism. Biometrics, in simple terms, means the static study of the physical and behavioral characteristics of living beings. bio- life plus metric measure. This term is also used as a way to uniquely identify an individual through his physical or behavioral characteristics.
As forms of security, biometrics is used for recognition, criminal identification, control of access to data and devices, etc. As each person is unique and has unique characteristics, both in physical and behavioral aspects, biometrics has proven to be a successful way to assist in the security of companies, government institutions and in other areas.
Biometric systems may require identification through different characteristics of a person’s body, such as the eyes, the fingerprints, and the retina, the iris of the eyes or even the palm of the hand. It is also possible that biometric systems can identify someone through their voice, the way they walk, the way they react to scares, etc.
Capture, extraction and comparison are the main components of a biometric system.
In the capture, it is possible to carry out the acquisition of a biometric sample to carry out the identification of an individual. This can be done by means of fingerprints or by reading the iris of the eye, for example. In the extraction, a sample of the individual’s unique biological information is removed, so that based on it, identification can be done. The result of this analysis is called a template. Finally, the comparison uses the stored template to compare it with someone else.
