New trend of smart epidemic prevention: multi-modal biometric technology of iris + face

“Electronic Sentinel” is a new product spawned by the Covid 19 epidemic. It is an integrated turnstile gates for temperature measurement and access control, which also can scan health codes, face verification or read ID cards. It is designed to quickly identify information such as real-time body temperature, health code status, nucleic acid test results and vaccinations of passersby.

After people pass the test, the flap barrier gates immediately open to allow people to enter the controlled area. , All tests do not require manual contact, are efficient and hygienic, and can effectively prevent the spread of germs.

Before the application of “electronic sentinel”, manual inspection often takes at least half a minute. When the traffic is large or the network signal is poor, there will be congestion problems, which requires more human and material resources to be allocated.

However, with the repetition and aggravation of the epidemic situation, a relatively large burden has been imposed on manpower epidemic prevention, which also puts forward new demands for intelligent epidemic prevention. Now, electronic sentries can check and pass in seconds, and and minimize physical contact.

Traditional single biometric identification is based on facial biometrics for identity determination. Although this identity recognition modality is more convenient, it has some shortcomings. During the epidemic prevention and control period, this widely used facial recognition technology will be affected by people wearing masks, protective clothing, goggles and turbans during the epidemic, which will hinder identification. At the same time, it is also difficult to solve the problem that the elderly cannot use their smartphones to show their health codes.

As a result, “iris + multi-modal, multi-functional artificial intelligence intelligent machine” and “iris + multi-modal recognition nucleic acid collection booth” were born. This is developed to meet the new needs of anti-epidemic and the technical iterative needs of the existing “digital sentinel” equipment.

The ID card information is read through multi-modal recognition of face + iris, etc., and the nucleic acid code status of ID card personnel, whether there are people in the community, vaccination status, etc. can be quickly fed back on the display screen.

The elderly no longer need to stand at the checkpoint for a long time, waiting for manual inspection. In addition to face and iris recognition, you can also quickly complete the inspection by swiping your ID card. Multi-mode biometrics + flap barrier gates make the normal travel of the elderly more convenient.

Multimodal Biometrics

The so-called multi-modal biometric technology refers to the fusion or integration of multiple human biometric features, using the characteristics and unique advantages of different biometric technologies, and combining data fusion technology to make the authentication and identification process more accurate and secure. The performance of the overall system meets the needs of different application scenarios.

“Multi-modal” refers to the use of computer vision to identify various modalities – the current international community and my country’s identification of people, epidemic prevention and control information (such as health code, application code, itinerary code, nucleic acid code, site code, etc. ) multiple authentication, as well as the identification and authentication of the owner of important objects (such as cars), the mainstream image and biometric identification modalities used.

To put it simply, the so-called multimodal biometric technology refers to the fusion or integration of multiple human biometric features. Using the characteristics and unique advantages of different biometric technologies, and combining data fusion technology to make the authentication and identification process more accurate and security. Thereby improving the performance of the overall system and meeting the needs of different application scenarios.

Nowadays, more and more communities, offices, commercial buildings, restaurants, cultural centers and playgrounds, etc., use flap barrier gates combined with multi-modal biometric technology for entrance control. It greatly improves the efficiency of personnel traffic management and reduces labor costs. It has become the optimal digital solution for the new normal of epidemic prevention.

Compared with single biometric technology, multimodal biometric technology has the following advantages in epidemic prevention and control:

Higher recognition accuracy

Multimodal biometrics is not a simple superposition of a single biometric, but a combination of face, iris and other biometrics through carefully designed fusion algorithms, which can complement information and further improve the accuracy of recognition.

Higher Security level

With the development of technology, it has become easier to steal, steal and copy information. Multimodal biometrics combines multiple biometrics at the same time, which can make up for the weakness that some biometrics are easy to be forged.

Wider application range

A single biometrics technology often has certain application limitations or is only suitable for some application scenarios, while multimodal biometrics can largely fill the application defects of single biometrics and expand the application scenarios.

Today, biometric features such as face and iris have become a key for people to enjoy digital life. Compared with single biometrics, multimodal biometrics increases the difficulty and complexity of forging personal biometrics and improves the security of personal biometrics.

Moreover, in the post-epidemic era, the basic requirements of epidemic prevention and control such as “zero contact” and “wearing masks” cannot be met by a single biometric technology. On the contrary, flap barrier gates combined with multi-modal biometric technology can intelligently control the crowd entering and meet the various needs changes in different applications.
