Access control systems are an essential part of security nowadays. In the past, password systems were used for security but with the passage of time hackers found ways to bypass those security systems. Then the era of identity cards began. This access control system is still being used by some companies. However, the more confidential places still have some doubt in mind. A more secure system is needed. Biometric access control systems are the answer.

A biometric access control system is based on several physical and behavioral aspects.

Physical Traits

Physical traits of a biometric access control system are related to shape of our body. Fingerprint, for example, is unique for all people. Face recognition is another trait. Palm print is another one. In face recognition, the factors include size of the nose, distance between nose and ear, distance between two eyes, any blemish, blot, etc. Retina/iris scan is one of the latest technologies being used. So all the factors that uniquely identify an individual are being used in biometric access control systems nowadays.

Behavioral Traits

Behavioral traits are related to the behavior of an individual. Typing rhythm is an example. The access control system requires the person to type some words and then identifies him/her on the basis of the rhythm. Gait is another behavioral trait. Everyone has a slightly different gait. Voice is another factor. Most biometric access control systems these days are already using voice recognition. There are many other factors in this category.

How Biometric Access Control System Works?

A biometric access control system works on verification. There could be more than one trait in a single system. The system first scans the person who wants to gain access to a restricted resource and then matches the data acquired from the scan with the stored data in the database. In this way, a person is verified and given access if he/she is found as authorized to access the secure resources or premises. Biometric access control systems are also used to identify a particular individual from a group of people. The process of identification is the same as described above.

Are These Systems Worth the Cost?

Biometric access control is a one-time cost system. It requires almost no maintenance. You just need to keep the database updated. This includes entering the data of authorized individuals for verification. As compared to older systems based on identity cards or password, biometric access control systems provide higher level of security. Breaching such security is very hard because duplicating biometric traits is virtually impossible. So there is no doubt on the level of security when it comes to biometric access control systems. They are worth the cost.

Conclusion

Biometric access control systems are worldwide popular systems these days. They are being used by most businesses and commercial organizations that require higher security to protect their valuable resources from unauthorized access. These systems are very fast and prove to be useful for the premises where thousands of people pass every day.
