Server System Automatic Authorization Token Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server systems require users to reauthorize services when the authentication server changes, even if the user's granted rights remain unchanged, leading to unnecessary user intervention.
Innovation Solution
A server system that automatically updates authorization tokens by determining if the new authentication system's rights are equal to or fewer than the old system's rights, allowing token renewal without user intervention when the authentication server is changed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the authentication server is changed to a new system, then the system can adopt a more advanced authentication mechanism, but users are required to reauthorize services even when their granted rights remain unchanged
Solution Approach 1:
The system automatically compares authorization information between the old and new authentication servers, and self-determines whether reauthorization is necessary based on scope comparison, eliminating the need for manual user intervention when rights remain unchanged
Solution Approach 2:
The system changes the parameter of authorization scope comparison to determine equivalence between old and new authorization information, allowing automatic transition when the scope of rights remains the same or is reduced
2Reliability
If the system requires users to reauthorize services when the authentication server changes, then security can be maintained by confirming user intent, but user workload increases and service continuity is interrupted
Solution Approach 1:
The system performs preliminary comparison of authorization scopes before requiring user action, pre-determining whether reauthorization is necessary by checking if the new authorization scope is equivalent to or narrower than the old scope
Solution Approach 2:
The system automatically handles the determination of whether reauthorization is needed by comparing authorization information, serving itself without requiring user intervention when the scope of rights remains unchanged
3Productivity
If the system automatically updates authorization tokens without user intervention, then service continuity is maintained, but security may be compromised by not confirming user intent
Solution Approach 1:
The system uses parameter comparison of authorization scopes to automatically determine when token updates are safe, checking whether the new scope is equivalent to or narrower than the old scope before proceeding with automatic updates
Solution Approach 2:
The system performs self-validation by comparing authorization information and automatically updating tokens when the comparison confirms that user rights remain unchanged or are reduced, maintaining security through automated equivalence verification
Data Source
AI summary
In a case in which information about authorization that is identified based on an authorization token issued in an old authentication system satisfies a condition, the old authorization token is updated with a new authorization token.
