Proper identification ensures and enhances security. New biometric technology developments are improving the quality and consistency of facial recognition security. Biometrics is gradually replacing traditional ID cards and passwords because they offer superior methods of building control and visitor authentication.
How It Works
Most facial recognition systems use CCTV cameras and proprietary software to automatically target faces and measure them based on unique algorithms. This process creates a mathematical face-print. The individual’s face-print code is encrypted to maintain privacy and integrity while it is routed to the central database. Once it arrives, the face-print is compared to watch-lists of state, federal, and sometimes global criminals or unauthorized personnel. Face-prints that do not result in any matches are usually deleted. If the image reaches a set confidence threshold, an operator is automatically alerted.
The Value of Facial Scanning Technology
Iris, hand, and fingerprint scanning systems have a disadvantage when it comes to security control. A person under surveillance doesn’t have a choice whether they want to willingly participate in the biometric scan. Iris scanning, hand geometry, and fingerprinting involve support staff and an individual’s time and commitment. Each person at the security checkpoint must stop, follow the instructions and participate in the process. This creates customer lines, traffic bottlenecks, inevitable delays, and frustration. Facial scanning and recognition systems avoid these problems.
Having security cameras and statistical algorithms do the work reduces human errors and minimizes profiling. Citizen privacy and false identifications are valid concerns. However, there are equally important technical challenges. Facial recognition quality depends on variables like distance, resolution, expression, face angle, the illumination between the image and mugshot, and more. In the real world, a person passing a random security camera will not naturally look at it or remove their hat or sunglasses. Therefore, having a professional security system at a controlled checkpoint is the best solution.
