Seat Departure Authentication Using Periodic Biometric Templates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In DaaS-based work environments, there is a need for enhanced security measures to prevent unauthorized users from accessing internal computer resources by periodically verifying user identity using biometric information.
Innovation Solution
A method and device that collect and manage biometric information using a template, allowing for aperiodic verification of seated users by matching extracted feature points with pre-registered templates to ensure only authorized individuals remain seated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information is collected continuously during the period user is seated, then authentication reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The system performs biometric authentication periodically at predetermined time intervals rather than continuously. The authentication server sends requests at specific intervals, and the local device collects biometric information only at these moments, reducing continuous monitoring complexity while maintaining security effectiveness.
Solution Approach 2:
The local device automatically collects biometric information when requested by the authentication server without requiring manual intervention. The system self-manages the authentication process by automatically comparing collected biometric data against stored templates and handling user notification, reducing operational complexity.
2Reliability
If biometric authentication is performed frequently, then security against unauthorized users is improved, but user convenience and system performance deteriorate
Solution Approach 1:
Authentication is performed at predetermined time intervals rather than continuously or too frequently. This periodic approach maintains security by regularly verifying user identity while avoiding excessive authentication requests that would inconvenience users and impact system performance.
Solution Approach 2:
The system adjusts authentication parameters including time intervals between requests and the type of biometric verification performed. By dynamically managing these parameters, the system balances security requirements with user convenience and system performance considerations.
3Speed
If biometric information is collected and stored locally, then authentication speed is improved, but data security and privacy protection worsen
Solution Approach 1:
The system extracts only essential biometric features and stores them as templates in an encrypted format on the authentication server rather than storing complete biometric data locally. This extraction approach enables fast authentication through template comparison while minimizing security risks by not retaining sensitive raw biometric information.
Solution Approach 2:
The authentication server acts as an intermediary that securely manages biometric templates and performs authentication comparisons. Instead of storing sensitive biometric data locally on the client device, the system uses the server as a secure intermediary to handle template storage and comparison, reducing local data security risks while maintaining authentication speed.

AI summary
A seat departure management method includes: collecting, by a local device provided in a seat, biometric information of a user during a period in which the user is seated in the seat; requesting, by an authentication server communicating with the local device, the biometric information at a specific time during the period in which the user is seated; extracting, by the authentication server, a feature point using the biometric information at the specific time; and matching, by the authentication server, the extracted feature point with a pre-registered template.
