Token-Based Collective User Data Disclosure Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for handling personal information, such as personal data stores and information banks, face inefficiencies when requesting agreements from multiple users for data disclosure, particularly in cases like medical research where numerous users need to agree, leading to increased workload and potential delays.
Innovation Solution
A communication method involving a non-transitory computer-readable recording medium that stores a program to facilitate the efficient acquisition of user data by transmitting request information to an agreement server, which issues tokens permitting data disclosure from users who have agreed, allowing for scheduled token requests and data acquisition from a data management server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual agreement requests are sent to each user for data disclosure, then user privacy protection is ensured, but the workload increases and delays occur when numerous users need to agree
Solution Approach 1:
The patent combines multiple individual agreement requests into a single collective agreement request. The agreement server consolidates requests from multiple users and issues a single token that represents aggregated authorization, thereby maintaining privacy protection while dramatically improving data acquisition efficiency when numerous users need to agree.
Solution Approach 2:
The patent creates a token that serves as a copy or representation of multiple individual agreements. Instead of handling each user's agreement separately, the system generates a single token that encapsulates the authorization from multiple users, reducing the complexity of managing numerous individual agreements while preserving the integrity of user consent.
2Reliability
If multiple individual agreement requests are processed sequentially, then each user's consent is properly obtained, but the time required for data acquisition increases
Solution Approach 1:
The agreement server performs preliminary consolidation of multiple agreement requests before issuing the token. By pre-processing and combining the requests in advance, the system ensures that all necessary user consents are properly obtained while minimizing the total time required, as the aggregation work is done proactively rather than reactively.
Solution Approach 2:
The patent enables continuous data acquisition by maintaining a valid token that represents ongoing authorization from multiple users. Once the token is issued, data can be continuously accessed without repeatedly seeking individual user consents, thereby reducing time loss while ensuring user consent validity throughout the data usage period.
3Productivity
If a simple token system is used for data access, then data acquisition is fast, but control over user data disclosure becomes complex when multiple users are involved
Solution Approach 1:
The agreement server acts as an intermediary between users and the data access system. It manages the complexity of multiple user agreements by issuing a single token that encapsulates all necessary authorizations. This intermediary approach maintains fast data access speed while hiding the underlying complexity of coordinating multiple user consents from the data access process.

AI summary
A procedure includes transmitting request information concerning user data requested to be collectively acquired, to an agreement server, requesting a token by scheduling a transmission timing of a token request for requesting to issue the token associated with a plurality of users from whom the agreement has been obtained among the users who fall under the request information, and by transmitting the token request to the agreement server in accordance with the scheduling, and acquiring, from a data management server, the user data not acquired yet in the user data on the users from whom the agreement has been obtained, by using the token acquired in the requesting the token.
