Biometrics in Physical Access Control
The role of biometrics in physical access control is to provide security and convenience. Given the new security-conscious climate and the reduction in cost for biometric devices, there is an increasing adoption based on security requirements. Physical access control is one of the most demanding applications of biometrics. As new opportunities for growth in the access control arena emerge, it is important to remember that biometrics is a technology, not an industry. Before applying any technology, it is always important to first identify the problem. Second, define a solution. Third, see how your technology can become part or all of the solution.
What Are Biometrics?
Biometric systems use automated techniques that verify or identify people by their physical characteristics. The dictionary definition of biometrics is "The measurement and analysis of unique physical or behavioral characteristics especially as a means of verifying personal identity." Unique physical features can mean anything from fingerprints and facial features to speech and keystroke patterns. Various technologies are currently available for biometric authentication, here are the big three biometric technologies used most frequently today
Fingerprint – This biometric modality was given a big leg up by Apple and other mobile smartphone manufacturers.
Facial recognition – There has been a big jump in this technology. Mobile device makers, such as Google's Pixel have adopted the technology while the use of AI and machine learning has made it more reliable.
Iris recognition technology – Considered the most accurate of the biometric technologies, iris recognition is non-invasive, non-contact and very fast.
