Authentication is an important activity performed several times a day. We authenticate people in day-to-day routine and allow them different level of access to different resources.
Biometric authentication is simple process of verifying your identity using your measurements or other unique characteristics of your body, then logging you in a service, an app, a device and so on.
Biometrics is the name for any type of body measurements and calculations.
Biometric authentication works by comparing two sets of data: the first one is preset by the owner of the device, while the second one belongs to a device visitor. If the two data are nearly identical, the device knows that â€œvisitorâ€ and â€œownerâ€ are one and the same, and gives access to the person.
So what are biometrics? Simply put, itâ€™s a technology that uses your unique qualities, like your fingerprints or facial features, to identify, well, you! By using your unique biological characteristics, you can provide measurements.
