3D Liveness Detection – A Revamped Biometric Face Identification

Liveness detection is a technology that uses 3D Liveness to verify whether the person is alive and physically present in front of the camera. Instead of using a 2D flat image, a 3D image focuses on the texture of the skin to identify the person in a picture. Besides, this technology plays a crucial role when it comes to security. Without 3D imaging, the biometric systems can be tricked which can lead to fraud and identity thefts. Individuals have been found involved in the fraud by wearing silicon masks in front of the camera. This system is being used in several institutions such as banks, airports, and many governmental organizations. 

Liveness Detection in Facial Recognition

Facial recognition involves the analysis of certain facial features including the distance between, the eyes, nose, and mouth. This evaluation is then converted into a digital pattern which is compared to others present in the database. This process involves structured lights, time-of-flight, or stereo vision to capture the 3D image of a face. These aspects help the system identify the real person in an image or a video. Here are a few steps that are included in the 3D liveness check:

• Active 3D sensing is the projection of infrared light onto a face to see how the face reacts to it. It is helpful in creating a 3D map.
• Passive 3D sensing doesn’t require any special light or rays and uses natural light to evaluate the depth of the face.
• Motion-based deepfake detection allows the person to make certain movements such as smiling and blinking to see the authenticity of the person.
• Texture analysis is another aspect that involves the change in the texture of the skin due to blood flow of the light angles. 

Applications of a 3D Liveness Check

It is a renowned system of verification which is being implemented throughout the world. It can be used in smartphones, facial verifications, biometric systems, preventing fraud, and access control in high-security environments, airports, and healthcare centers. 

• Facial Authentications

This technology is widely used in facial authentication. The system thoroughly scans the face, its texture, movements, and reflection of light to verify its authenticity. 

• Smartphones and Laptops

The gadgets also use this technology to get access. There are various processes for verification in smartphones and laptops such as passwords and PINs. But facial recognition is quicker than others.

• Biometric Systems

There are numerous biometric systems that involve facial liveness checks in offices, banks, and other buildings. The system compares the facial features with the existing database for verification. 

• Financial Sectors

Facial liveness detection is more useful when implemented in financial sectors like banks. It helps to verify the customers and use their faces to prevent any fraud and identity theft. 

• Access Control

There are institutions that need a high-security access control environment such as military areas, government buildings, research labs, and data centers. A Liveness check is crucial in such places. 

• Airports and Prisons

A Liveness check is a quick method of verification that is helpful in places like airports where everybody is in a hurry and has to get verified timely. 

• Healthcare Centers

Healthcare professionals also use this technology to ensure the safety of the patients and it promotes safe treatments with the identification of the individuals. 

Future Trends in 3D Face Liveness Detection

AI is transforming itself over time. With the advancement, the liveness check will likely improve in terms of better and enhanced sensors and cameras. It will help in capturing more depth and detailed images of a person. Besides, advanced algorithms should be incorporated in the system which can help in the effective prevention of fraud by detecting the spoof timely. 

Moreover, the liveness detection online systems will be more adaptive and real-time based. It will update the algorithms based on the environment and the behavior of the users. In addition, the time will come when this technology will be incorporated into the doorbells, smartwatches, and other accessories to provide security. 

Conclusion

With the evolution of technology, this system is expected to provide more accuracy, wider adoption, and expanded use cases in various sectors. The Liveness check will be at the spearhead when it comes to security, unlocking the devices, getting access, gaming, and verification purposes. Lastly, the incorporation of enhanced algorithms can also revamp the quality and credibility of the system.
