Biometric Technology - Application Trends in Access Control Systems

Editor's Note: Biometric products can be individually identified by human physical characteristics. The size and shape of the hand, fingerprints, sounds, and the iris and retina all have their own unique attributes. This type of equipment is now used in access control systems in many commercial buildings around the world. It is foreseeable that biometrics will become the first choice for access control and high-end applications.

Application development of biometrics In 1970, modern biometrics technology was already used in access control systems. However, due to the high cost of biometric identification products at the time, the earliest applications were limited to high security environments. In recent years, with the declining prices of microprocessors and the emergence of advanced electronic imaging components, the cost has been reduced and the accuracy of biometric products has been improved. Therefore, more and more biometric products have been applied to some commercial access control systems. in. Biometrics technology is no longer just a technology for nuclear facilities.

However, due to the bottleneck of technological development, the biometric authentication model still has certain problems in terms of stability, application cost, and system construction difficulty. At present, fingerprint products occupy a dominant position. Others, such as face recognition, finger veins, and palm shape recognition, are still in the stage of promotion and application. There are also data showing that face, finger vein, and palm shape recognition are frequently used in high-end fields at home and abroad.

Application advantages of biometrics The purpose of using access control systems is to allow authorized persons to access specific locations. Only using biometrics can achieve this goal. Smart card systems can only monitor the use of authorized cards and cannot control who uses smart cards. The cryptosystem can also only recognize a specific set of numbers and cannot identify people using this set of numbers. The biometric device can identify whether the person is authorized by palms, eyes, fingerprints or voice.

Biometric devices can also replace smart cards. Although the cost of smart cards has declined in recent years, it is still necessary to reduce the cost of management in order to truly replace smart cards. Because the smart card must be replaced after the card is lost, the time cost increases. And people’s eyes and palms are basically not lost, stolen or forgotten, and certainly not replaced.

Conclusion With the increase in the number of users of biometric products, the acceptance of biometric products by users is also increasing. The purpose of the access control system is to control whether people can enter. Only biometrics really have this capability.
