Dynamic Permission Attributes for Secure Artifact Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In permission-protected archives, users can only search and access artifacts they own or have explicit permission to, limiting the sharing of relevant but privately owned artifacts that are not accessible due to restrictive permission settings.
Innovation Solution
Introducing a 'search permission' attribute that allows private artifacts to be accessible if a search algorithm determines them highly relevant to a user's query, enabling the system to request permission from the artifact owner for access and modifying permissions dynamically based on responsiveness scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permission-protected archives enforce strict access control, then security is improved, but information sharing capability deteriorates
Solution Approach 1:
The permission attribute is made dynamic rather than static. Artifacts can have different permission states depending on the search context: normally private, but can become temporarily accessible when a search algorithm determines high relevance to a user's query. This resolves the contradiction by allowing strict permission enforcement in normal operations while enabling information sharing when scientifically justified by search relevance.
Solution Approach 2:
The system changes the permission parameter based on search responsiveness. When an artifact's responsiveness score to a search query exceeds a threshold, the permission attribute transitions from restricting access to allowing access. This parameter change enables the system to maintain security for irrelevant artifacts while sharing relevant private artifacts, thus resolving the contradiction between security and information sharing.
2Ease of operation
If users can only access artifacts they own or have explicit permission for, then permission control is maintained, but access to relevant private artifacts deteriorates
Solution Approach 1:
The search algorithm acts as an intermediary between users and private artifacts. Instead of direct access control, the search algorithm evaluates the relevance of private artifacts to user queries and mediates access by temporarily modifying permission attributes for highly relevant results. This intermediary mechanism maintains permission control for the system while enabling access to relevant private artifacts that would otherwise be lost.
3Reliability
If permission attributes restrict artifact access, then security is improved, but search result completeness deteriorates
Solution Approach 1:
The system applies partial permission relaxation only to artifacts that meet the responsiveness threshold, rather than universally. The search algorithm identifies specific private artifacts with high relevance scores and temporarily modifies their permission attributes only for those cases. This partial action maintains security for the majority of artifacts while recovering relevant information in search results, resolving the contradiction between security and completeness.

AI summary
Among other things, we describe techniques for receiving a list of artifacts that are stored in an archive and are responsive to a search query issued by an entity. A set of artifacts are identified that each have a permission attribute indicating that the respective artifact is accessible to the entity when the respective artifact is responsive, above a threshold responsiveness value, to the search query issued by the entity.
