Biometric Ticket Issuing System Using Feature ID Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ticket verification methods using facial authentication pose risks of personal information leakage and inefficiencies due to large image data sizes, leading to potential fraud and processing delays.
Innovation Solution
A ticket issuing system that uses a feature value table to store and match biometric data, issuing tickets with a feature ID instead of direct biometric information, and a ticket checking apparatus that verifies the feature ID against stored data to authenticate ticket holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If facial images or feature values are recorded on tickets for authentication, then ticket verification accuracy is improved, but personal information leakage risk increases
Solution Approach 1:
The patent extracts only the essential authentication elements (feature values derived from facial images) and records them on tickets, while keeping the original facial images stored securely in a database. This separation allows verification without exposing personal information, resolving the contradiction between verification accuracy and information leakage risk.
Solution Approach 2:
The patent introduces feature values as an intermediary between facial images and authentication. Instead of directly using facial images for verification, the system converts them into feature values that retain authentication capability while removing personally identifiable information, thus preventing information leakage while maintaining verification accuracy.
2Measurement precision
If facial images are recorded on tickets for authentication, then verification accuracy is improved, but processing time increases
Solution Approach 1:
The patent extracts feature values from facial images before recording them on tickets. These pre-processed feature values are compact and can be quickly compared during verification, eliminating the need for time-consuming image processing at the verification stage while maintaining authentication accuracy.
Solution Approach 2:
The system performs the complex facial feature extraction and analysis in advance when issuing tickets, storing the resulting feature values on the tickets. During verification, only a simple comparison of these pre-computed feature values is needed, significantly reducing processing time while maintaining verification accuracy.
3Reliability
If electronic tickets using smartphones are used for authentication, then security is improved, but accessibility deteriorates
Solution Approach 1:
The patent creates a universal ticket system where authentication data can be stored on multiple media types including paper tickets, electronic tickets, and smartphone-based tickets. The verification process remains the same regardless of the medium, allowing users with or without smartphones to access the same secure authentication system.
Solution Approach 2:
Instead of requiring users to have smartphones for secure authentication, the patent inverts the approach by making the ticket itself (in any form) the secure carrier of authentication data. The smartphone becomes just one of many possible delivery mechanisms rather than a mandatory requirement, thus maintaining security while improving accessibility.
Data Source
AI summary
A ticket issuing system has a processor and a storage with instructions thereon. The storage stores a feature value table that associates and stores feature value data including feature information pertaining to biometric information and a feature ID for identifying the feature value data. The instructions upon execution by the processor, cause the processor to: acquire user feature information pertaining to biometric information of a user of a ticket to be issued; identify, from among the feature value data stored in the feature value table, similar feature value data for which a similarity with the user feature information satisfies a predetermined criterion to obtain a feature ID corresponding to the similar feature value data; and issue a ticket on which authentication information that includes the feature ID corresponding to the similar feature value data is recorded.
