Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If face identification data is frequently updated to improve authentication accuracy, then measurement precision is improved, but loss of time increases due to more frequent updates and processing
Solution Approach 1:
The system updates face identification data at predetermined intervals (periodically) rather than continuously or on every authentication attempt. The face identification data registration section determines whether to update based on timing conditions, implementing periodic action to balance accuracy improvement with time efficiency.
Solution Approach 2:
The update frequency and timing are made dynamic rather than fixed. The face identification data registration section determines update timing based on various conditions (authentication success/failure, number of attempts, time of day), allowing the system to adapt update frequency to current operational context to optimize the balance between accuracy and time consumption.
2Adaptability or versatility
If face authentication is performed in diverse shooting environments, then adaptability is improved, but measurement precision deteriorates due to environmental variability
Solution Approach 1:
The system performs preliminary actions to prepare for environmental variations by accumulating face identification data from multiple shooting conditions over time. The face identification data registration section collects and stores data under various environmental conditions (different lighting, angles, distances) so that the authentication system has pre-prepared reference data to handle diverse shooting environments accurately.
Solution Approach 2:
The system changes parameters of the face identification data to adapt to different shooting environments. By updating face identification data with variations in lighting conditions, camera angles, and distances, the system modifies its reference parameters to maintain authentication accuracy across diverse environmental conditions.
3Reliability
If face identification data is updated at all timings to ensure latest information, then reliability is improved, but device complexity increases due to continuous monitoring and processing
Solution Approach 1:
Instead of continuous updating, the system implements periodic updates at predetermined timings. The face identification data registration section is activated at specific intervals or under specific conditions rather than continuously monitoring and processing, reducing device complexity while maintaining data freshness through regular periodic updates.
Solution Approach 2:
The system extracts and processes only the essential update operations at predetermined timings rather than continuously processing all possible updates. The face identification data registration section is selectively activated based on timing conditions, separating the critical update function from continuous monitoring to reduce overall system complexity.
Data Source
AI summary
An information processing device includes an image acquirer that acquires a shot image of a user, a registered user information holder that holds face identification data of a registered user, and a face authentication section that detects a face image of a registered user existing in the shot image by using face identification data held in the registered user information holder. The information processing device further includes an information processing section that executes information processing based on a detection result by the face authentication section, and a face identification data registration section that updates the face identification data based on a face image extracted from a shot image of a user at predetermined timings. The face identification data registration section determines whether or not to update the face identification data with a condition corresponding to a situation in which the timing is generated.
