Group Management Server Using QR Codes for Secure Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information sharing techniques lack a seamless and user-friendly method for group management, access control, and resource sharing, particularly in dynamic environments like meetings or project collaborations, where users need to easily join and leave groups and access shared folders with secure and efficient access rights management.
Innovation Solution
An information sharing system comprising a group management server and mobile terminals that utilize optically readable marks, such as two-dimensional barcodes or dot patterns, to share group IDs, server addresses, and access rights, allowing users to join or leave groups by imaging and analyzing these marks, which are then converted into icons for easy access and management of shared folders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If QR codes are used to distribute electronic data to large audiences, then distribution efficiency is improved, but access control and security management become difficult
Solution Approach 1:
The patent segments the audience into specific groups with defined access rights. Instead of distributing generic QR codes to all attendees, the system creates group-specific QR codes that grant access only to authorized individuals. This segmentation maintains distribution efficiency while enabling precise access control through group-based permissions.
Solution Approach 2:
The patent applies local quality by assigning different access rights to different groups. Each group receives QR codes with specific permission levels tailored to their role or affiliation. This allows the system to maintain efficient distribution while ensuring that each user receives appropriate access control based on their specific needs and authorization level.
2Reliability
If manual access right management is implemented, then security is improved, but administrative complexity increases
Solution Approach 1:
The patent implements self-service by enabling users to automatically join groups and receive appropriate access rights through QR code scanning. The system automatically manages user registration, group assignment, and permission configuration without requiring manual administrative intervention for each user. This maintains security through automated authorization while significantly reducing administrative complexity.
Solution Approach 2:
The patent applies preliminary action by pre-configuring group access rights and permissions before distribution. Administrators set up group structures and access levels in advance, then distribute QR codes that automatically apply these pre-defined permissions. This eliminates the need for real-time manual configuration while maintaining security through pre-established authorization policies.
3Ease of operation
If group sharing is enabled for collaboration, then ease of operation is improved, but access control management becomes complex
Solution Approach 1:
The patent applies universality by creating a multi-functional QR code system that handles multiple tasks simultaneously. The same QR code mechanism enables users to join groups, receive access rights, and share resources without requiring separate systems for each function. This maintains ease of operation through a unified interface while managing access control complexity through centralized group-based permission management.
Data Source
AI summary
An information sharing system includes a group management server and at least one terminal. The group management server includes a mark generating circuit that generates a group ID for uniquely identifying a group. The terminal includes a mark analysis circuit that analyzes the imaged mark; and a second communication control circuit that controls the second communication circuit to communicate with the group management server and the file server, and sends a request for the user ID stored in the second storage circuit based on the analysis results to join the group indicated by the group ID. The shared folder management circuit of the group management server set an access right for the received user ID on the shared folder when receiving the request from the terminal.
