Distributed Workflow environment of the adaptivity of Color Matching of access control model

Abstract

To in distributed workflow environment inIn order to make user get the most appropriate of permissions to implementation workflow taskOften need to user are assigned the role.For a group given authorization. of user best role Matching ProblemPut forward a kind of distributed workflow environment of the adaptivity of Color Matching of access control model.The model can according to workflow of different taskFrom System of role in looking for related task implementation permissions of a group or multi-role collectionThen reference environment,Time Constraint and role between the inheritance relationship to the matching optimizationFinal for user select optimal of role collection.Experimental show thatThe model can eliminate redundant roleFor user accurate distribution a group the smallest role collectionSo as to achieve role matching optimization of objective.
