Conventional access control systems face challenges and security risks

Conventional Access Control System With the improvement of the security, advancement, and stability requirements of access control systems in China, the currently used access control systems mainly include fingerprints, palm-shaped, iris, and biometric recognition systems represented by radio frequency cards. Common access control systems include: password access control systems, contact card access control systems, contactless card access control systems, and biometric access control systems. At present, fingerprint access control systems are more commonly used. The Fingerprint Access Control System replaces traditional keys and existing IC and ID cards with fingers. It utilizes the anisotropy and invariability of human fingerprints to provide users with safe and reliable encryption means. When used, they only need to place their fingers on the fingerprints. On the acquisition window of the acquisition instrument, the task of unlocking can be completed and the operation is very simple.

New Challenges and Potential Safety Risks Although access control systems such as fingerprints, palm shapes, irises, and other biometric identification systems not only need security, convenience, and manageability, they also have their own specialties, but fingerprint identification methods themselves have serious security risks. .

· This type of biological exposure to the outside of the human body is easier to replicate;

· High requirements on the environment, sensitive to finger humidity, cleanliness, etc. Dirty, oil, and water can cause unrecognized or influencing recognition results;

Some people or some groups have few fingerprint features or even no fingerprints, so it is difficult to image; for low-quality fingerprints such as peeling and scars, it is difficult to identify and have low recognition rate.

It is difficult to register and identify some special populations such as some manual laborers with a lot of hands;

Fingerprints can not be scratched, the eyes can not be swollen and bleeding, the face can not be injured and so on, and even the number of beard will affect the accuracy and sensitivity of the recognizer.

With the development of society and the acceleration of the pace of life, the flow of people in public places such as office buildings, libraries, etc. is getting bigger and bigger. Controlling the normal operation of these places and ensuring public safety has become an important task for management organizations. From the perspective of energy conservation and environmental protection, China has a population of over 100 million, and the amount of access card holdings is considerable. With the major trends and new requirements for energy conservation and environmental protection, new breakthroughs in the access control system are the key. How to combine medical science and biometric energy-saving advantages with the advantages of traditional access control cards is the question that security guards need to ponder.
