摘要： 针对基于角色的存取控制模型不适合跨组织环境的问题，扩展组织内部以角色为基础的存取控制，采用一种角色分数机制，并在水平式跨组织工作流程环境中的使用者、角色及工作之间加上更严谨的限制条件，让使用者在虚拟角色集合中，选择一个适当的角色进入跨组织工作流程内执行工作。实验结果证明，该扩展简单有效，企业在进行跨组织工作流程时更具公平性及安全性。

Abstract: The Role-based Access Control(RBAC) is widely applied because of its advantages. For the unsuitability of RBAC in inter-organization environment, the main propose of this research is to extend the characteristics of RBAC on intra-organization workflow. The research puts forward a role score mechanism, and appends more strict constraint to users, roles and activities of horizontal inter-organization workflow. Besides, this research makes sure that a user chooses an appropriate role from virtual role set to execute activity in inter-organization workflow. Proved by the experiment, the extension is simple and effective, and it makes the enterprises more equitable and securable in inter-organization workflow.

Key words: intra-organization, inter-organization, horizontal inter-organization, workflow, role, access control
