Local Entity Database Authentication for Secure Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital communications systems face challenges in securely sharing sensitive data due to the risk of malicious entities accessing user data, as existing systems lack effective mechanisms to reliably authenticate entities and prevent unauthorized access.
Innovation Solution
A method and system that store authorized and unauthorized entity databases locally, allowing for real-time authentication of remote systems by comparing their identifiers with both databases before granting access, thereby preventing unauthorized data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If entity authentication is performed by querying a centralized authorisation system in real-time, then data security is improved, but system processing burden increases and performance degradation occurs
Solution Approach 1:
The patent applies preliminary action by obtaining and storing the authorised entity database in advance at the data management system, before actual data access requests occur. This allows the system to perform local authentication checks without real-time queries to the centralized authorisation system, thus maintaining security while improving processing efficiency during data access operations.
Solution Approach 2:
The patent applies copying by creating a local copy of the authorised entity database at the data management system. Instead of repeatedly querying the centralized system, the local copy enables fast authentication checks while the centralized system is queried only periodically to update the copy, thereby reducing the processing burden on both systems during normal operations.
2Device complexity
If entity authentication is performed using only an authorised entity database, then system complexity is reduced, but security reliability deteriorates due to potential outdated information
Solution Approach 1:
The patent applies feedback by implementing a periodic update mechanism where the data management system queries the centralized authorisation system at scheduled intervals to refresh the local authorised entity database. This feedback loop ensures the local database remains current with any changes in authorised entities, maintaining authentication accuracy without requiring continuous real-time connections.
Solution Approach 2:
The system performs preliminary updates of the authorised entity database at scheduled intervals before authentication needs arise, ensuring the local database contains current information. This preliminary action maintains reliability while avoiding the complexity of real-time validation for each authentication request.

AI summary
A computer-implemented method for sharing user data associated with a first user. The method comprises receiving, from a second system, a first access message associated with a request for access to the user data stored at a first system. The first access message comprises a second system label indicative of an identifier of the second system. In response to receiving the first access message, the second system label is compared with a plurality of authorised entity labels and a plurality of unauthorised entity labels. In response to identifying that the second system label matches an authorised entity label and that the second system label does not match an unauthorised entity label, a grant message is transmitted indicative that the request for access is granted.
