A fine-grained access control model for knowledge graphs

Abstract

Nowadays Knowledge Graphs are a common way to integrate and manage all the information that an organization owns. This involve also sensitive domains like security, so the management of access control on these graphs became crucial. Due to their dimension, Knowledge graphs are often stored using NoSQL solutions, that have very poor support to access control. In this paper a distributed and secure Knowledge graph management system is presented. The system supports both open and closed access control and its architecture guarantees the management of very large knowledge graph.
