LIVENESS TEST METHOD AND LIVENESS TEST APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18456713 titled 'LIVENESS TEST METHOD AND LIVENESS TEST APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for conducting a liveness test. The method involves the following steps:
- Determining the presence of a subject using a radar sensor.
- Performing a first liveness test on the subject based on radar data obtained by the radar sensor.
- Acquiring image data of the subject using an image sensor, if the subject is present and the result of the first liveness test satisfies a first condition.
- Performing a second liveness test on the subject based on the acquired image data.
Potential applications of this technology:
- Biometric authentication systems: The liveness test method can be used to ensure that the subject being authenticated is a live person and not a spoofing attempt using a static image or a replica.
- Access control systems: The liveness test can be employed to verify the presence of an authorized person before granting access to a secure area.
- Financial transactions: The method can be utilized to confirm the presence of the account holder during high-value transactions, reducing the risk of fraud.
Problems solved by this technology:
- Preventing spoofing attacks: By combining radar and image data, the method can detect and prevent spoofing attempts using static images or replicas.
- Enhancing security: The liveness test adds an additional layer of security to biometric authentication systems, access control systems, and financial transactions by ensuring the presence of a live person.
Benefits of this technology:
- Improved accuracy: By using both radar and image data, the liveness test method can provide more accurate results compared to using a single modality.
- Real-time detection: The method allows for real-time detection of the subject's presence and liveness, enabling quick decision-making in authentication or access control scenarios.
- User-friendly: The use of radar and image sensors makes the liveness test non-intrusive and convenient for the subject, enhancing user experience.
Original Abstract Submitted
Disclosed is a liveness test method and liveness test apparatus. The liveness test method includes determining a presence of a subject using a radar sensor, performing a first liveness test on the subject based on radar data obtained by the radar sensor, in response to the subject being present, acquiring image data of the subject using an image sensor, in response to a result of the first liveness test satisfying a first condition, and performing a second liveness test on the subject based on the image data.
