File Management System Using Personal ID Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conference systems face challenges in securely managing file access rights, particularly in multipoint remote conferences, where authentication methods are inconvenient and position-based authentication fails, leading to unauthorized access.
Innovation Solution
A file management system that uses personal IDs for authentication, dynamically controls file operations based on access rights, and displays icon status changes to reflect access permissions, incorporating a camera for facial recognition and databases to manage access rights and file operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is required for each file access operation, then file security is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary authentication by acquiring personal IDs from participants before the conference starts. This authentication result is stored and reused throughout the conference, eliminating the need for repeated authentication operations during file access, thus maintaining security while improving ease of operation
Solution Approach 2:
The system automatically manages authentication states and file access rights without requiring manual intervention from participants. The conference server automatically determines whether a participant can access a file based on their pre-acquired personal ID and the file's access conditions, eliminating the need for participants to manually authenticate for each file access
2Reliability
If login processing is performed for each participant, then access control is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs login processing and acquires personal IDs at the beginning of the conference as a preliminary action. This initial authentication establishes the participant's identity and access rights for the entire conference duration, eliminating the need for repeated login operations and improving ease of operation while maintaining access control
Solution Approach 2:
The personal ID acquired through initial login serves multiple functions throughout the conference: it identifies the participant, determines their access rights to different files, and enables automatic authorization checks. This universal identifier eliminates the need for separate login operations for each file access
3Ease of operation
If position-based authentication is used, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The system introduces personal IDs as an intermediary that bridges the gap between ease of operation and authentication reliability. Instead of directly relying on position information alone, the system uses personal IDs (which can be obtained through various means including position-based methods) as a more reliable intermediate authentication mechanism that works consistently across different conference scenarios

AI summary
A method for managing a file includes: acquiring at least one personal ID for identifying a person associated with the right to access a file; setting a file operation method depending on whether or not a combination of the acquired personal ID satisfies a condition set for each type of operation for the file; and controlling a file operation based on the set file operation method.
