Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single iris image is directly acquired and stored for identification, then the identification process is simple and fast, but the iris information is easily leaked and stolen, causing security risks
Solution Approach 1:
The patent segments the iris feature acquisition process into multiple independent imaging modes (first light spot imaging mode, second light spot imaging mode, etc.), where each mode captures different characteristics of the iris. This segmentation ensures that no single image contains complete iris information, thereby enhancing security while maintaining system functionality.
Solution Approach 2:
The patent introduces a new dimension of security by using multiple light spot imaging modes that capture iris features from different perspectives or under different conditions. This multi-dimensional approach ensures that stolen or leaked images cannot be easily used for unauthorized identification, as they lack the complete multi-modal feature set.
2Reliability
If multiple light spot imaging modes are used to acquire iris features, then security is enhanced by preventing unauthorized access, but the system complexity and acquisition time increase
Solution Approach 1:
The patent performs preliminary action by pre-establishing the correspondence between different light spot imaging modes and storing the extracted iris features from each mode in advance. During actual identification, the system quickly retrieves and matches the pre-extracted features, significantly reducing the time required for multi-mode imaging and processing.
3Reliability
If multiple light spot imaging modes are implemented, then device compatibility and security are improved, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing the iris recognition system to support multiple light spot imaging modes within a single device framework. The system can adaptively select and use different imaging modes (first light spot mode, second light spot mode, etc.) based on the specific device characteristics, ensuring broad compatibility while maintaining security through multi-mode feature extraction.

AI summary
An iris feature acquisition policy of an iris identification device for a user is determined, the iris feature acquisition policy indicates a manner of acquiring an iris feature by using light spot imaging, and the iris feature acquisition policy includes one or more light spot imaging modes. One or more light spot iris images of the user are acquired based on the one or more light spot imaging modes and by using the iris identification device. Feature extraction is performed respectively on the one or more light spot iris images to obtain one or more light spot iris features. A light spot iris identification feature of the user under the iris feature acquisition policy is determined based on the one or more light spot iris features. The light spot iris identification feature is stored with identification information of the user into a database associated with the iris identification device.
