Research on Organizational Collaboration Oriented OB4LAC in E-government

With the development of collaborative electronic government system and the development trend of organizational collaboration in e-government. More and more e-government systems and safety platforms are developed and deployed. All of these bring the problems of collaborative electronic government system safety and integration of complicated systems, businesses and resources. One of the keys to solve these problems is the access control and authorization management of systems. In this paper, the Organization Based 4 Level Access Control (OB4LAC) is extended, and we propose the Organizational Collaboration Oriented OB4LAC (OB4LAC^C). Through the study of inter-organizational security collaboration schema based on OB4LAC^C, we discussed the OB4LAC^C application in the inter-organizational security collaboration. And we resolved lots of issues in the inter-organizational security collaboration, such as permission to enlarge and Conflict of permission.
