A Fine-Grained Access Control Model and Implementation

The several models and solutions were introduced and implemented to address privacy and security issues during past decades. However, the most advanced role-based access control models support coarse-grained access control and widely used open source frameworks cannot provide efficient and effective fine-grained solution. We introduce a general fine-grained access control model and provide an implementation by extending Spring Security framework. Our model is tightly coupled with database access control at row-level and is separated from business functions of the application.
