Face Authentication Re-Authentication Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems face inefficiencies in environments where people move, as re-authentication attempts may fail due to individuals leaving the authentication area before re-authentication can be completed.
Innovation Solution
An information processing apparatus that includes authentication circuitry for performing face authentication and control circuitry for determining the order of re-authentication based on attributes related to time changes in face images, such as features that are likely to change or remain constant over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If re-authentication is performed on all persons who failed authentication, then authentication coverage is improved, but authentication efficiency deteriorates due to people moving out of the authentication area before re-authentication can be completed
Solution Approach 1:
The patent changes the parameter of re-authentication timing by introducing a priority order based on time-change attributes. Instead of uniform re-authentication, the system dynamically adjusts the timing and order of re-authentication attempts according to each person's attribute characteristics, thereby improving efficiency while maintaining coverage.
Solution Approach 2:
The patent applies different re-authentication strategies to different individuals based on their specific attribute characteristics. By categorizing persons into different priority groups according to their time-change attributes, the system provides localized optimization for each person rather than applying a uniform approach to all.
2Speed
If re-authentication is performed immediately on failed authentication cases, then response speed is improved, but authentication accuracy deteriorates because moving persons may leave the authentication area
Solution Approach 1:
The patent performs preliminary classification of persons into priority groups based on their attribute characteristics before executing re-authentication. This preliminary action allows the system to prepare an optimized re-authentication sequence in advance, balancing response speed and accuracy by anticipating which persons are most likely to remain in the authentication area.
Solution Approach 2:
The patent introduces dynamic adjustment to the re-authentication process by using time-change attributes to determine priority order. The system adaptively adjusts the re-authentication timing and sequence based on the dynamic characteristics of each person's attributes, rather than using a fixed immediate re-authentication approach.
3Device complexity
If uniform re-authentication order is used for all persons, then system complexity is reduced, but authentication efficiency deteriorates in dynamic environments where people move
Solution Approach 1:
The patent introduces a new parameter dimension for re-authentication ordering based on time-change attributes. By adding this parameter, the system transforms from a simple uniform ordering approach to a more sophisticated attribute-based priority ordering, improving efficiency without excessive complexity increase.
Solution Approach 2:
The patent segments the re-authentication process by dividing persons into different priority groups based on their attribute characteristics. This segmentation allows the system to handle different groups with different strategies, improving overall efficiency while maintaining manageable system complexity through structured categorization.

AI summary
An information processing device is equipped with: an authentication circuit that authenticates a person on the basis of a facial image of the person in captured image data; and a control circuit that controls the order of re-authentication of a plurality of people for which authentication failed, on the basis of information pertaining to attributes related to temporal changes in facial images.
