A Fine-grained Access Control Model for Knowledge Graphs
Proceedings of the 17th International Joint Conference on e-Business and Telecommunications, 2020 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 ...

Redundancy and information leakage in fine-grained access control [PDF]
Proceedings of the 2006 ACM SIGMOD international conference on Management of data, 2006 The current SQL standard for access control is coarse grained, in that it grants access to all rows of a table or none. Fine-grained access control, which allows control of access at the granularity of individual rows, and to specific columns within those rows, is required in practically all database applications.
