Authentication Apparatus Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 1-to-N authentication systems, variations in environmental factors and feature characteristics lead to multiple candidates being extracted, necessitating the input of identification information to switch to 1-to-1 authentication, which is not always necessary.
Innovation Solution
An authentication apparatus that includes a feature acquiring unit, an extracting unit, a determining unit, a first identifying unit, and a second identifying unit, which compares features, determines similarity, and requests identification information only when necessary, allowing for identification without switching to 1-to-1 authentication in cases where multiple candidates are not indicative of the original person.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple candidates are extracted in 1-to-N authentication, then the authentication system can handle environmental variations, but identification information must be input to switch to 1-to-1 authentication
Solution Approach 1:
The system automatically determines whether multiple candidates are indicative of the original person using determining units, and automatically switches between 1-to-N and 1-to-1 authentication modes without requiring user intervention. The authentication apparatus performs self-judgment on whether identification information input is necessary, making the system operate autonomously based on the extraction results.
2Measurement precision
If identification information input is required to switch to 1-to-1 authentication, then accurate identification can be achieved, but authentication efficiency decreases
Solution Approach 1:
The system dynamically adjusts the authentication mode based on the determination results. When multiple candidates are not indicative of the original person, the system maintains 1-to-N authentication without requiring identification information. When they are indicative, the system switches to 1-to-1 authentication requiring identification information. This dynamic adaptation optimizes both accuracy and efficiency.
Solution Approach 2:
The system changes the authentication parameter (mode) based on the determination of whether multiple candidates are indicative. It transitions between two authentication modes: 1-to-N mode (no identification information required) and 1-to-1 mode (identification information required). This parameter change allows the system to balance accuracy and efficiency based on real-time conditions.
3Reliability
If the system always requires identification information for multiple candidates, then identification accuracy is ensured, but unnecessary steps are added when not needed
Solution Approach 1:
The determining units perform preliminary judgment on whether multiple candidates are indicative of the original person before requiring identification information input. This preliminary action filters out cases where identification information is unnecessary, allowing the system to proceed directly to identification without the extra step of requesting and verifying identification information, thus saving time while maintaining reliability.

AI summary
An authentication apparatus includes a feature acquiring unit that acquires a feature of an authentication target; an extracting unit that extracts one or more registered persons having features similar to the acquired feature; a determining unit that determines whether any registered person having a feature similar to the feature of at least one extracted registered person exits in the registered persons; a first identifying unit that, if the determination is negative, identifies the registered person having the feature having a highest degree of similarity with the acquired feature as the authentication target; a specific information accepting unit that accepts information specific to the authentication target; and a second identifying unit that, if the determination is affirmative and the accepted specific information coincides with the information specific to any extracted registered person, identifies the registered person having the coinciding specific information as the authentication target.
