Presence-Aware Biometric Authentication for Impersonation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication technologies, such as those described in Patent Literature 1 and Patent Literature 2, are susceptible to impersonation when multiple users with similar biometric features are present in the same facility, leading to security vulnerabilities.
Innovation Solution
An authentication system that includes first authentication means for users checking in at a place, prediction means to identify potential impersonation risks based on user presence or arrival patterns, and processing execution means to enforce additional authentication measures during predicted vulnerable periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication is used for user identification, then authentication speed and convenience are improved, but security deteriorates when multiple users with similar biometric features are present
Solution Approach 1:
The system performs preliminary registration of multiple users with similar biometric features in advance. During authentication, the system proactively identifies potential impersonation risks by comparing the authenticated user's biometric data against registered similar users, and preemptively notifies facility managers before granting access, thereby preventing security incidents before they occur
Solution Approach 2:
The system establishes a feedback loop where authentication results are continuously monitored and compared against registered similar users. When potential impersonation is detected, the system provides feedback notifications to facility managers, who can then verify the user's identity through alternative means, creating a closed-loop security mechanism that continuously improves authentication reliability
2Reliability
If additional authentication measures are implemented during vulnerable periods, then security is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary registration of multiple users with similar biometric features in advance. During authentication, the system proactively identifies potential impersonation risks by comparing the authenticated user's biometric data against registered similar users, and preemptively notifies facility managers before granting access, thereby preventing security incidents before they occur
Solution Approach 2:
The system applies additional verification measures selectively rather than universally. When biometric authentication succeeds, the system checks whether the authenticated user has similar registered users present in the facility. Additional verification steps (such as manager notification or alternative authentication) are applied only in these specific high-risk cases, not for all users, thereby balancing security enhancement with system simplicity

AI summary
An authentication system, comprising at least one processor configured to: execute first authentication for a first user when the first user is present at a first place or arrives at a first place; predict a predicted period in which a second user who has a possibility of being authenticated as the first user by the first authentication is not expected to be present at the first place or arrive at the first place, based on at least one type of information out of second-time information about a second time at which the second user has been present at a second place or has arrived at a second place and second-place information about the second place; and execute first processing for the first user based on the first authentication executed in the predicted period.
