Blockchain Entity Group Management via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available group management platforms are limited in their functionality and vulnerable to attacks, lacking effective security and control over group membership and service access.
Innovation Solution
A blockchain-based system is implemented for each entity group to manage membership and control access to services, utilizing a decentralized ledger for secure transaction recording and permission management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If commercially available group management platforms are used, then basic group management functionality is provided, but security against attacks and control over group membership is insufficient
Solution Approach 1:
The patent divides the centralized group management system into separate blockchain instances, one for each entity group. Each blockchain independently manages membership and access control for its specific group, segmenting the security management function to reduce centralized vulnerability while maintaining overall system reliability.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary between the group management system and service access control. The blockchain acts as a trusted mediator that records membership information and enables decentralized authentication, eliminating the need for complex centralized authentication mechanisms while enhancing security.
2Adaptability or versatility
If commercially available group management platforms are used, then group management functionality is provided, but functionality is limited
Solution Approach 1:
The patent creates a universal blockchain-based platform that can serve multiple entity groups with different functionality requirements. The same blockchain infrastructure supports various services (messaging, scheduling, collaboration) for different groups, enabling the system to adapt to diverse needs without requiring separate specialized platforms for each function.
Solution Approach 2:
The patent implements dynamic access control where service permissions can be changed in real-time based on membership status and group requirements. The blockchain records these dynamic changes, allowing the system to adapt functionality on-demand while maintaining a relatively simple underlying structure that evolves with group needs.
3Reliability
If a blockchain instance is maintained for each entity group, then security and access control are enhanced, but system complexity increases
Solution Approach 1:
The patent segments the access control function by creating separate blockchain instances for each entity group. This segmentation isolates security management for each group, preventing security issues in one group from affecting others, while the modular nature of blockchain makes the complexity manageable through standardization.
Solution Approach 2:
The patent implements self-service mechanisms where the blockchain automatically enforces access control policies based on recorded membership information. The system self-manages authentication and authorization without requiring complex external management overhead, as the blockchain's immutable ledger and consensus mechanisms inherently provide secure access control.

AI summary
As described herein, a system, method, and computer program are provided for blockchain-based entity group management. An instance of a blockchain is maintained for each entity group of a plurality of defined entity groups. Further, the instance of the blockchain maintained for each entity group of the plurality of defined entity groups is utilized to manage group membership for the entity group, and control access by members of the entity group to a plurality of services having functionality configured for the plurality of defined entity groups.
