Concerning of the website group system, this paper proposes a new solution of graduation authorization management, which can improve the efficiency of resources management, optimize the distribution of management permissions and improve the efficiency of foreground permission check. This paper analyzes the properties and limitations of several common website group systems in permission management and introduces this solution´s improved design ideas and key techniques, including fast generation algorithm of pruning channel tree, roles filtering, stage-by-stage permission filtering, concurrency collision avoidance, etc. This solution is successfully applied in the new version of Tsinghua University information release system.
