Cheng Wang · Computer Systems and Applications · 2010
To meet the actual demand of oil network information system in B/S model,and to improve dynamics of users’authority management and security of authorized access,this paper presents a fine-grained privilege management model combining the role-based access control principle for the fact that users are complicated and they change jobs frequently in B/S application system.This model decomposes the access privilege of sources by fine-grained,and realizes access control of different levels from coarse-grained to fine-grained,and this model cannot only authorize the role but also authorize the user directly,which greatly improves the flexibility and scalability.
