Biometric security systems are reliable ways to improve a building’s physical and digital security. Biometric systems represent one part of comprehensive security access control systems that work together to provide complete security to one’s home or business. However, there tends to be a lot of dramatizations of these systems in pop culture. Today, we’ll sift through some common misconceptions of biometric security access control systems.
Tricking Devices and Scanners
Pop culture and the internet is littered with articles and how-tos claiming to teach one how to trick a fingerprint-based biometric system. Today, biometric fingerprint systems have sophisticated algorithms and extremely high image quality. Faking a fingerprint when these complex security traits are present is a very complicated task; it is more than just using tape on a wine glass! In most cases, the biometric security access control device is managed and audited by security personnel. Pairing these two concepts makes it nearly impossible to deceive an authentic fingerprint security access control system or device successfully.
A Macabre Misconception
A typical gimmick seen in TV and movies is to use a removed body part from the real person as a method to bypass the biometric security access control. This would very rarely work. When the initial biometric scan is taken, there is usually some effect on the scan. This is prompted due to the user being alive. If a body part is removed, the reading might fail to be accepted by the system due to not being in the same state as when it was first scanned. Consider a person’s pulse in their finger. Their pulse might have been picked up in some manner during the initial scan. But, when a malicious user tries to use the removed finger, it may not have the same “alive likeness” down to the degree the biometric scanner is capable of observing. This is because the pulse is not present in the removed finger.
Accuracy of Biometric Systems
The accuracy of a biometric system when comparing two entities is superb, given today’s technology. However, simply because the biometric system identifies an entity is the same as an initial prescanned entity, this does not mean the person is the same. Biometric security access control systems, while extremely powerful, are best supplemented with other security access control devices. After all, authentication and authorization are two different things. The accuracy of a biometric system is wholly dependent on the quality of the prescanned entity. This becomes the basis for how accurate the system can be when scanning potential matches. In fact, similar to other security systems, biometric access control systems may need real-time data to function correctly.
