Data Access Management by Confidentiality and User Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access management systems fail to adaptively manage user access to data based on the confidentiality of the data and reliability of the user, leading to potential information security breaches or hindered collaboration due to uniform access control.
Innovation Solution
An access management apparatus that manages user access based on a confidentiality score of the data and a reliability score of the user, applying basic and special conditions to ensure both information security and accessibility, including monitoring measures and multiple authentication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform access control is applied to all users regardless of their reliability, then information security is improved, but collaboration efficiency deteriorates
Solution Approach 1:
The patent applies local quality by differentiating access control policies based on user reliability levels. Instead of uniform access control, the system assigns different access rights to different users according to their individual reliability scores, thereby maintaining information security while enabling efficient collaboration for reliable users.
Solution Approach 2:
The patent implements dynamic access control where access rights are not fixed but adjusted based on changing user reliability scores. The system continuously evaluates user behavior and updates access permissions accordingly, allowing flexible adaptation between security and collaboration needs.
2Reliability
If access is uniformly denied to outside workers, then information security is improved, but business progress deteriorates
Solution Approach 1:
The patent changes the parameter of access control from a binary yes/no decision to a graded system based on reliability scores. By introducing reliability score as a variable parameter, the system can dynamically adjust access levels, allowing outside workers with high reliability scores to access necessary data while maintaining security.
Solution Approach 2:
The system performs preliminary evaluation of outside workers' reliability before granting access. By assessing reliability scores in advance and establishing access rights based on these evaluations, the system enables business progress for qualified workers while maintaining security safeguards.
3Productivity
If access rights are granted without considering data confidentiality levels, then collaboration efficiency is improved, but information security deteriorates
Solution Approach 1:
The patent applies local quality by matching user reliability scores with data confidentiality levels. Different confidentiality levels are assigned to different data, and access rights are granted based on the correspondence between user reliability and data sensitivity, ensuring that collaborative access does not compromise security.
Solution Approach 2:
The system creates a composite access control mechanism that combines multiple factors including user reliability scores, data confidentiality levels, and access right conditions. This composite approach integrates security requirements with collaboration needs into a unified access decision framework.
