Inter-Organizational Information Linkage System with Trusted Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information linkage systems, such as WO 2003/105002 A1, fail to facilitate accurate personal authentication and information linkage across multiple organizations, lacking mechanisms for inter-organizational information sharing and user consent, which hinders the creation of new businesses and efficient data utilization.
Innovation Solution
An inter-organizational information linkage system comprising a processor and storage device that transmits and receives identification and authentication information between organizations, ensuring secure and consent-based linkage of personal information across multiple organizations, utilizing an information linkage server, application server, authentication information generation server, and database server to manage and share data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If personal information is linked across multiple organizations, then the quality and quantity of shared data increases, but the risk of impersonation and authentication accuracy deteriorates
Solution Approach 1:
The patent introduces a trusted third-party authentication service as an intermediary between organizations. This service issues authentication tokens that verify user identity across organizational boundaries, ensuring that personal information linkage maintains high authentication accuracy while enabling data sharing. The intermediary validates identities before allowing information exchange between organizations.
2Reliability
If user consent mechanisms are implemented for information linkage, then information security improves, but system complexity increases
Solution Approach 1:
The patent implements preliminary consent acquisition where users provide authorization for information linkage before any data exchange occurs. The system captures user consent in advance through authentication tokens and permission settings, then automatically enforces these permissions during information linkage operations. This preliminary action ensures security requirements are met while avoiding complex real-time consent management.
3Adaptability or versatility
If inter-organizational information linkage is implemented, then new business creation opportunities increase, but the difficulty of managing authentication and consent across organizations increases
Solution Approach 1:
The patent creates a universal authentication and consent management platform that serves multiple organizations simultaneously. The system provides standardized authentication token issuance, validation, and consent management functions that work across different organizational boundaries. This multi-functional platform enables diverse business collaborations while maintaining consistent security and authentication management protocols.

AI summary
Provided is an information linkage system, comprising: a processor; and a storage device coupled to the processor, the storage device holds identification information of a user and information on the user, which are added by a first organization, in association with each other, the processor: transmits to a second organization an information linkage application regarding information on any one item included in the information on the user; acquires, when the information linkage application is received, identification information of the user and information on the user of the item specified by the information linkage application, which are added by the second organization; and stores the acquired information in the storage device in association with the identification information of the user and the information on the user regarding the same user as a user identified by the acquired identification information, which are added by the first organization.
