Access Control Recognition: Fingerprint-to-face technology in-depth articles

[IT168 technology] In order to further meet the high security requirements, the access control system has also undergone changes in RFID card access control, fingerprint access control, iris recognition access control, and facial recognition access control systems.

Fingerprint and face recognition

First, fingerprint identification access control

Fingerprint access control system is the use of human biometric fingerprints for identity security identification, with irreplaceable, non-replicable and unique features, it uses high-tech digital image processing, biometrics and DSP algorithms and other technologies for access control security, In and out personnel identification control is a new generation of access control systems that meet modern security requirements. The system replaces traditional keys and existing IC and ID cards with fingers. It uses the anisotropy and invariability of human fingerprints to provide users with safe and reliable encryption means. When using the fingers, they need only to place their fingers on the fingerprint collector. On the collection window, you can complete the unlock task and the operation is very simple. In addition, traditional mechanical locks, identification cards, and code locks are prevented from being lost due to the loss and misappropriation of keys, the forgery of identification cards, or the decipherment of code locks. At the same time, the system also has a screen Chinese character display function, thereby enhancing the protective measures for access control. Achieve security management functions.

Second, facial recognition access control

Facial recognition is also called face recognition, face recognition, face recognition, etc. The following are all called face recognition. Areas protected by security can identify the identity of the person trying to enter through face recognition. Face recognition systems can be used for business, residential security and management.

Facial recognition is based on the human facial features to identify the technology, including standard video recognition and thermal imaging technology.

Standard video recognition records the facial features such as the eyes, nose and mouth of the person being photographed through a common camera, converts it into a digital signal, and then uses a computer for identification. Video facial recognition is a common form of identification and is now widely used in public security.

Thermal imaging technology primarily produces facial images by analyzing the thermal radiation generated by facial blood. Unlike video recognition, thermal imaging does not require a good light source and can be used even in dark conditions.

The intelligentization and biochemistry of the access control system mark another milestone in the security industry. With the support of new technologies, access control systems will inevitably lead to new glories.

The advantages and applications of fingerprint recognition technology

Fingerprint identification technology was developed earlier in the field of biometrics. As the longest-running biometric technology in R&D history, it has many advantages:

2. Everyone's fingerprints are quite fixed and it is difficult to change;

3, easy to get fingerprint samples, easy to develop identification system, strong practicality;

4, a person's fingerprints are not the same, can improve the security of the system;

5. The fingerprint template (sample) is not a fingerprint but a key feature extracted from the fingerprint. In this way, the storage capacity of the stored fingerprint template is much smaller than the stored fingerprint.

6. When reading the fingerprint, the user must contact the finger and the fingerprint collector. The direct contact with the fingerprint collector is the most reliable way to read human biometrics. This is also one of the main reasons why fingerprint recognition technology can occupy most of the market;

7, the fingerprint collector can be more compact, and the price will be even lower.

Thus, fingerprint identification technology is currently the most convenient, reliable, non-invasive and inexpensive biometric technology solution, and has great potential for large-scale applications.

When the recognition object is unaware of the completion of the recognition process, the recognition object does not have psychological rejection emotions;

Intuitiveness is outstanding: the human face is undoubtedly the most intuitive source of information that can be discerned by the naked eye, and the face recognition technology is based on the facial image of human beings, which is convenient for manual confirmation and auditing. “Taking appearances for people” is consistent with the cognitive laws of people;

It is not easy to counterfeit: face recognition technology requires that the recognition object must be in person to identify the scene, and it is difficult for others to counterfeit. The unique activity identification capability of the face recognition technology ensures that others cannot use the inactive photos, puppets, wax figures to deceive the recognition system. This is Fingerprint and other biometric identification technologies are difficult to achieve;

The recognition accuracy is high and the speed is fast: compared with other biometric technologies, the recognition accuracy of face recognition technology is at a high level, and the misrecognition rate and rejection rate are low;

Use of general-purpose devices: Devices used in face recognition technology are generally PCs, cameras, and other general-purpose devices. Since computers and closed-circuit television monitoring systems have been widely used, the face recognition technology is used for most users. No need to purchase a large number of special equipment, both to protect the user's original investment and greatly expand the system's functionality, while also improving the system's security performance, to meet the user's security needs;

In a nutshell, face recognition technology is a high-precision, easy-to-use, high-stability, hard-to-counterfeit, and cost-effective biometric recognition technology with an extremely broad market application prospect.
