Dynamic Access Control for Data Objects via Collaborative Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data sharing technologies lack flexibility in controlling access, often resulting in either unrestricted sharing leading to loss of control for the original user or highly restricted access, failing to meet users' intuitive expectations about data ownership and control, especially in scenarios requiring temporary or conditional access.
Innovation Solution
A method is introduced that establishes an access control policy defining collaborative conditions for data access, monitoring users for compliance, and providing access only when a predetermined number meet these conditions, ensuring flexible and controlled access through geographical, temporal, or other specified criteria, using encryption and secret sharing algorithms for secure data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If document sharing is freely allowed without technical hindrance, then ease of operation is improved, but control over the document by the original user is lost
Solution Approach 1:
The patent implements dynamic access control where sharing permissions are not static but change based on real-time conditions. The system monitors collaborative conditions (such as user presence, device proximity, or network status) and automatically adjusts access levels. This allows the original user to maintain control while enabling flexible sharing - the document can be accessed freely when conditions are met, but access is automatically restricted when conditions change, resolving the contradiction between ease of sharing and maintaining control.
2Adaptability or versatility
If document security is applied to restrict access, then control over the document is maintained, but ease of operation deteriorates due to highly restricted access
Solution Approach 1:
The system implements self-service access control where the monitoring of collaborative conditions and enforcement of access policies occurs automatically without requiring manual intervention from the original user. Once the document is shared with security policies, the system autonomously evaluates whether collaborative conditions are met and grants or denies access accordingly. This maintains strong control flexibility while preserving ease of operation, as users don't need to manually manage permissions - the system handles it automatically based on predefined conditions.
3Productivity
If real-time collaborative editing is implemented, then productivity is improved, but device complexity increases due to interface inefficiencies
Solution Approach 1:
The patent introduces an intermediary layer that mediates between multiple users and the document. This intermediary system handles the complex logic of real-time collaboration, including conflict resolution, version control, and access policy enforcement. By placing this intermediary layer between users and the document, the system enables efficient real-time collaborative editing while abstracting away the complexity from individual user interfaces. Users interact with simple, intuitive interfaces while the intermediary manages the sophisticated coordination required for productive collaboration.
Data Source
AI summary
A method and system are provided for enabling collaborative access to a data object. The method comprises establishing an access control policy, the access control policy defining at least one collaborative condition under which access to the data object is permissible, monitoring a plurality of users for compliance with the collaborative condition and providing access to the data object after a predetermined number of the users meet the at least one collaborative condition.
