What is biometric security?
It involves using biometric security software to automatically recognise people based on their behavioural or biological characteristics. The biometric technology currently used most often in physical access control is fingerprint recognition because of its lower price. Among 2D fingerprint sensors, multispectral sensors are often a better choice over optical sensor. They are slightly more expensive but offer higher accuracy and more reliable performance.
There is no doubt that Biometric systems are the future, however, if biometric applications are to be accepted, user convenience is of utmost importance.
For high- security environments, iris recognition provides the best accuracy, followed by palm vein recognition. Some biometric security systems verify identities using one or more detection technologies, while others do not verify the identity at all to keep costs low.
What benefits do biometric security systems offer?
Biometric systems strengthen security
One of the key benefits of biometric security devices is that they can help to increase your protection. It is much harder, for example, to clone or steal a fingerprint than an access card. In situations where you need to increase security, biometrics can also be used for multifactor verification. After someone’s presented their badge, for example, they then need to present their fingerprint to verify that they are who they claim to be. This is safer than using a PIN for verification as that can easily be passed to other people.
Biometric systems improve convenience
Biometric security systems can also offer users more convenience. It is easy to forget a card or key, but you always have your biometrics with you. And if the identifier allows hands-free or long-distance recognition, the convenience levels increase further – you may be allowed to enter your building simply by having your face scanned as you pass the entrance.
