Cloud Service Role Segmentation for Privilege Security

The patent segments user privileges into two distinct categories: contract administrator privileges and general user privileges. Contract administrators are granted specific privileges related to contract management (viewing contract information, managing service usage), while general users receive only the minimum necessary privileges for their operational tasks. This segmentation prevents general users from accessing contract-related functions and other departments' privileges, thereby resolving the contradiction between ease of operation and privilege security.

The patent applies local quality by assigning different privilege characteristics to different user roles. Contract administrators are given a specific set of privileges localized to contract management functions, while general users have privileges localized to their operational tasks. This localized privilege assignment ensures that each user group has exactly the privileges needed for their specific functions, preventing erroneous operations while maintaining system configuration simplicity through automated role-based assignment.

The patent implements self-service by enabling contract administrators to autonomously manage their own privileges and the privileges of users within their contracted services. The system automatically assigns appropriate privileges based on the contract configuration, eliminating the need for tenant administrators to manually manage each user's privileges. This self-service mechanism maintains reliability through automated consistent privilege assignment while significantly improving productivity by reducing the administrative burden on tenant administrators.
