Conditional Permission Delegation via Credential Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method for delegating permissions associated with credentials in a controlled and conditional manner, particularly in terms of geographic and temporal constraints, which can lead to misuse or unauthorized access.
Innovation Solution
A system that allows users to delegate permissions by associating them with conditions, such as geographic or temporal restrictions, by modifying existing credentials or creating new ones, using representations like QR codes for validation, ensuring that permissions are only usable when conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If permissions are delegated without conditions, then ease of operation is improved, but security and control deteriorate
Solution Approach 1:
The patent applies parameter changes by introducing conditional parameters (geographic location, time of day, duration) to the permission delegation process. The credential system dynamically adjusts permission validity based on these parameters, allowing easy delegation while maintaining security through conditional constraints on when and where permissions can be exercised.
2Reliability
If geographic and temporal constraints are added to permissions, then security is improved, but device complexity increases
Solution Approach 1:
The patent implements nesting by embedding multiple layers of constraints within the credential structure. Geographic围栏, temporal restrictions, and duration limits are nested within the permission framework, allowing the system to maintain a unified credential interface while incorporating complex security conditions without proportionally increasing operational complexity.
3Adaptability or versatility
If permissions are made transferable to other users, then adaptability is improved, but control and authorization deteriorate
Solution Approach 1:
The patent uses the credential as an intermediary that mediates permission transfer between users. The credential system acts as a trusted intermediary that verifies and enforces authorization rules during transfer, enabling adaptable permission sharing while maintaining centralized control and authorization integrity through the credential validation mechanism.
Data Source
AI summary
In one implementation, a computer system maintains one or more permissions associated with a credential held by a first user, where at least one of the one or more of permissions is delegatable by the first user to one or more other users. The computer system receives an indication that the first user has chosen to delegate a particular permission from amongst the one or more permissions to a second user, wherein the particular permission is needed to perform a particular type of action. Based on the first user indicating a choice to delegate the particular permission to the second user, the computer system associates the delegation of the particular permission with the second user. Based on delegating the particular permission with the second user, the computer system enables the second user to perform the particular type of action.
