Payment-Specific Face Authentication for Transit Ticket Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ticket checking systems using face authentication gates face a trade-off between reducing erroneous charging and maintaining passage ratio, with tighter criteria increasing erroneous authentication rates and looser criteria decreasing passage efficiency.
Innovation Solution
A ticket checking system that adjusts face authentication criteria based on payment methods, allowing commuter pass holders to meet a first criterion for gate passage and deposit balance users to meet a tighter second criterion, with separate settlement processing for each, and includes refund processing for unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the criterion of face authentication is tightened, then the rate of erroneous authentication is reduced and incidence of erroneous charging of fare is reduced, but the passage ratio of gate deteriorates and convenience is impaired
Solution Approach 1:
The patent applies different authentication criteria (first criterion for commuter pass, second tighter criterion for deposit balance payment) to different user groups based on their payment method. This local differentiation allows the system to maintain high reliability for fare collection (tighter criteria for deposit balance users) while preserving passage efficiency for commuter pass holders.
Solution Approach 2:
The system dynamically adjusts the authentication threshold parameter based on the payment method detected for each user. By changing the criterion parameter (first vs. second criterion), the system optimizes the balance between authentication accuracy and passage efficiency for different payment scenarios.
2Productivity
If the criterion of face authentication is loosened, then the passage ratio of gate improves, but the rate of erroneous authentication increases and incidence of erroneous charging of fare rises
Solution Approach 1:
Different authentication strictness levels are applied locally to different payment methods. Commuter pass users experience looser authentication (higher passage ratio) while deposit balance payment users face tighter authentication (higher reliability), resolving the contradiction through localized quality differentiation.
3Ease of operation
If a single face authentication criterion is used for all users, then the system is simple to operate, but it cannot simultaneously ensure high authentication accuracy and high passage efficiency
Solution Approach 1:
The system automatically detects the user's payment method and applies the appropriate authentication criterion without requiring user input or complex configuration. This maintains ease of operation while implementing differentiated authentication quality for different user groups.
Solution Approach 2:
The system autonomously determines which authentication criterion to apply based on the detected payment method, eliminating the need for manual intervention or complex user settings. The system self-adjusts the authentication strictness according to the user's payment type.

AI summary
An information processing apparatus includes a determination unit that determines, by face authentication, a person who has passed through a gate of a ticket barrier of transportation, a settlement processing unit that performs settlement processing of a fare for the determined person, a transmission unit that transmits, to a terminal of the determined person, information indicating that the transportation has been utilized, and a refund processing unit that executes refund processing for the settled fare in a case where predetermined information is acquired from the terminal.
