Face Authentication Data Damage Detection and Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Face authentication systems fail to function properly if the registered face identifying data becomes damaged, requiring a method to restore functionality without user intervention.
Innovation Solution
An information processing device with an image obtaining section, a registered user information retaining section, a face authenticating section, and a damage determining section that detects and notifies damaged face identifying data, allowing users to reregister their face data for login purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face identifying data is stored for authentication, then user authentication convenience is improved, but data damage risk increases causing system failure
Solution Approach 1:
The damage determining section performs preliminary detection of face identifying data integrity before authentication processing. By checking data validity in advance, the system prevents authentication failures caused by damaged data, thus maintaining reliability while preserving convenience.
Solution Approach 2:
The notifying section provides feedback to users when face identifying data is detected as damaged. This feedback mechanism allows users to understand the system state and take appropriate actions (such as re-registering face data), thereby restoring system reliability without compromising user convenience.
2Speed
If face identifying data is registered in advance, then authentication speed is improved, but system recovery capability deteriorates when data is damaged
Solution Approach 1:
The system automatically detects damaged face identifying data through the damage determining section and notifies users via the notifying section. This self-service approach enables automatic problem detection and user guidance for recovery, maintaining fast authentication while improving recovery capability when data damage occurs.
Solution Approach 2:
By performing damage detection before authentication processing, the system prepares for potential data issues in advance. This preliminary action allows the system to maintain normal authentication speed for valid data while providing a clear recovery path when damage is detected, thus resolving the contradiction between speed and recovery capability.
Data Source
AI summary
An image obtaining section 106 obtains an imaged image from an imaging device. A face authenticating section 132 detects a face image of a registered user present in the imaged image using face identifying data retained in a registered user information retaining section 180. A damage determining section 142 determines whether or not the face identifying data read from the registered user information retaining section 180 by a face data reading section 130 is damaged. If the face identifying data is determined to be damaged, a notifying section 144 notifies that the face identifying data is damaged.
