KNOWLEDGE GRAPH ACCESS CONTROL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240028764 titled 'KNOWLEDGE GRAPH ACCESS CONTROL SYSTEM
Simplified Explanation
The patent application describes a knowledge graph access control system that includes an arithmetic device and a storage device. The storage device stores obfuscation structure information, which defines the inclusion relationship between elements with different degrees of obfuscation in a knowledge graph, and access control information for managing user's access rights to each element in the obfuscation structure.
The arithmetic device is responsible for acquiring a target knowledge graph and generating an obfuscation knowledge graph by obfuscating the target knowledge graph for a specific user. This is done by referencing the obfuscation structure information and the access control information. In the obfuscation process, the original elements in the target knowledge graph are converted into obfuscation elements that the user has access rights to, while still maintaining the inclusion relationship defined by the obfuscation structure information.
- The patent application describes a knowledge graph access control system.
- The system includes an arithmetic device and a storage device.
- The storage device stores obfuscation structure information and access control information.
- The arithmetic device acquires a target knowledge graph and generates an obfuscation knowledge graph.
- The obfuscation is done based on the obfuscation structure information and access control information.
- The original elements in the target knowledge graph are converted into obfuscation elements that the user has access rights to.
- The obfuscation structure information defines the inclusion relationship between elements with different degrees of obfuscation.
Potential applications of this technology:
- Data privacy protection in knowledge graphs
- Secure sharing of sensitive information in knowledge graphs
- Controlled access to specific elements in a knowledge graph
Problems solved by this technology:
- Ensuring data privacy and security in knowledge graphs
- Managing access rights to specific elements in a knowledge graph
Benefits of this technology:
- Enhanced data privacy and security in knowledge graphs
- Improved control over access rights to knowledge graph elements
- Facilitates secure sharing and collaboration in knowledge graphs
Original Abstract Submitted
a knowledge graph access control system includes an arithmetic device and a storage device. the storage device stores obfuscation structure information that defines an inclusion relationship between elements with different degrees of obfuscation in a knowledge graph, and access control information for managing user's access rights to each element included in the obfuscation structure information. the arithmetic device is configured to acquire an obfuscation target knowledge graph, generate an obfuscation knowledge graph by obfuscating the target knowledge graph for a first user with reference to the obfuscation structure information and the access control information, and in the obfuscation of the target knowledge graph, convert an original element included in the target knowledge graph to an obfuscation element to which the first user has access rights in the access control information, and which includes the original element in the obfuscation structure information.
