Person Estimation Control to Limit Inappropriate Face Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Face recognition techniques pose risks of violating privacy and human rights, particularly when used inappropriately, such as in public places or on large numbers of unspecified individuals, necessitating a need for control mechanisms to prevent such violations.
Innovation Solution
A control apparatus with an image obtaining unit, person estimation unit, status monitoring unit, and estimation control unit that determines the use status of face recognition processing and limits or stops the processing to prevent inappropriate use, including scene recognition and face detection to identify public places or large numbers of unspecified individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If face recognition processing is performed to enable authentication and estimation functions, then service functionality is improved, but privacy and human rights violations may occur
Solution Approach 1:
The system performs preliminary scene recognition and use status determination before executing face recognition processing. By detecting whether the scene is a public place and assessing the use status in advance, the system prevents inappropriate face recognition operations from occurring, thus avoiding privacy violations while maintaining legitimate authentication functions
Solution Approach 2:
The system continuously monitors the use status of face recognition processing and provides feedback control. When inappropriate use is detected (such as processing in public places or on large numbers of unspecified individuals), the system stops or limits the processing, creating a feedback loop that prevents harmful actions while allowing appropriate services to continue
2Reliability
If face recognition processing is continuously executed to maintain authentication capability, then service availability is improved, but network load increases
Solution Approach 1:
Instead of continuously executing face recognition processing, the system performs it periodically based on detected use status. When the scene is identified as appropriate (non-public place) and use status is confirmed, processing is executed; when inappropriate conditions are detected, processing is stopped. This periodic action maintains service availability when needed while reducing network load during inappropriate periods
Solution Approach 2:
The system dynamically adjusts the execution of face recognition processing based on real-time scene recognition and use status determination. The processing is enabled or disabled according to current conditions rather than running continuously, allowing the system to adapt its behavior to minimize network load while maintaining service availability when appropriate conditions exist

AI summary
A control apparatus includes an image obtaining unit configured to obtain an image including a person, a person estimation unit configured to execute estimation processing to estimate information about the person based on the image and output a result of the estimation processing, a status monitoring unit configured to determine a use status of the estimation processing by the person estimation unit, and an estimation control unit configured to limit at least one of the estimation processing and the output of the result of the estimation processing by the person estimation unit based on a result of the determination of the use status by the determination unit.
