Whether the face recognition access control display supports liveness detection technology to prevent photo or video deception is an important indicator for evaluating its security and reliability.
Face recognition access control display plays a vital role in modern security systems. In order to ensure the security of the access control system, many high-end face recognition access control displays are equipped with liveness detection technology.
Liveness detection technology is a biometric technology that aims to verify whether the detected object is a real live object. It determines whether the user is a real live object by analyzing subtle features in the face image, such as skin texture, reflection, moiré, etc. This technology can effectively resist non-live attacks such as photos and videos to ensure the security of the access control system.
In face recognition access control display, there are various ways to implement liveness detection technology. Some products use silent liveness detection technology, and the system can automatically complete the detection without the user's active cooperation. This method improves the convenience and concealment of the system and can complete the detection without the user's knowledge.
Other products use cooperative liveness detection technology, which requires the user to complete a series of actions according to the system prompts, such as blinking, opening the mouth, shaking the head, etc. This technology relies on facial key point positioning and face tracking technology, and judges the authenticity of the user by analyzing whether the user's actions conform to the preset rules. Although the user's cooperation is required, it can obtain more effective live feature information and improve the recognition accuracy.
In addition, some high-end face recognition access control displays use binocular or near-infrared liveness detection technology. These technologies can use dual cameras to capture the three-dimensional information of the face, or determine whether the user is a real live person by analyzing the characteristics of reflected light. These technologies have higher security and stability and are suitable for identity authentication scenarios with high security requirements.
Therefore, when choosing a face recognition access control display, you should pay attention to whether it supports liveness detection technology and understand the specific implementation method and performance. By choosing products with liveness detection technology, the security and reliability of the access control system can be greatly improved.
Face recognition access control display supports liveness detection technology, which is an important means to ensure its security and reliability. When choosing a product, you should fully understand the performance and characteristics of its liveness detection technology to meet actual needs.
