Combined Access Rights Lattice for Heterogeneous Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face complexity in managing access rights for data of heterogeneous origin, where data from multiple sources is combined, making it difficult to determine appropriate access levels for users.
Innovation Solution
A system creates a combined access rights lattice that integrates access rights from various sources, allowing for granular control over data access by determining which data to provide based on specific access rights associated with each part of the combined data, and uses existing rights to reestablish access when rights change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a system combines access rights from multiple data sources, then the ability to control access to heterogeneous data is improved, but the complexity of managing access rights increases
Solution Approach 1:
The patent segments access rights management by creating separate access rights lattices for different data sources (internal data lattice and external data lattice), then combining them through a unified access rights lattice. This allows granular control over access to heterogeneous data while managing complexity through modular organization of access rights from different origins.
2Reliability
If granular access control is implemented for each part of combined data, then data security is improved, but the difficulty of determining appropriate access levels increases
Solution Approach 1:
The patent introduces an intermediary access rights lattice structure that mediates between multiple data sources and users. This lattice combines access rights from internal and external data sources, providing a unified mechanism to determine appropriate access levels granularly for each part of combined data, thus maintaining security while simplifying access level determination.
3Reliability
If access rights are strictly enforced for heterogeneous data, then data security is maintained, but the loss of access when rights change occurs
Solution Approach 1:
The patent implements dynamic access rights management where the system continuously monitors changes in access rights from external data sources. When rights change, the system dynamically adjusts the combined access rights lattice and notifies relevant users, allowing access to be reestablished when appropriate, thus maintaining security while minimizing access loss.
Data Source
AI summary
Systems and methods are provided for controlling access to data of heterogeneous origin. A system creates combined access rights from access rights and other access rights for combined data that includes data and other data. The system receives a request to access data that is part of the combined data. The system determines whether to provide access to at least part of the data based on access rights that are part of the combined access rights. The system provides access to at least part of the data in response to a determination to provide access to at least part of the data based on the access rights that are part of the combined access rights.
