Treffer: Improvement of Permission Management System Based on RBAC(Role-Based Access Control) Model.

To address the limitations of the traditional RBAC (Role-Based Access Control) model, particularly its inability to fulfill the requirements for hierarchical permissions and dynamic management in a business approval system, this paper introduces a new role-based access control model. This novel model is capable of dynamically creating, assigning, or revoking permissions, thereby achieving resource separation and multilevel permission management effectively. To demonstrate the model's feasibility, we applied it to a practical project. In this project, the JavaScript scripting language and the widely-used SSH (Struts2, Spring, Hibernate) framework were employed to implement the new model, which showcases enhanced capabilities in multi-level and dynamic multi-role permissions management.
