چکیده انگلیسی
Highly decentralized, dynamic and fine-grained access control models of social networks need that the access control mechanisms of social networks own sufficient expressiveness and flexibility. Most of current authorizations are difficult to satisfy the requirements of social network. Some access control models need a centralized access control mode or implementation. Some access control models use hybrid declarative/imperative languages with operational semantic. This paper develops an access control model of social network based on distributed logic with active rules and triggering mechanism, which we call DUD_RuleSN, a rule-based access control model of social network based on distributed updatable datalog. The logic makes the model a powerful authorization expressiveness and flexibility that can meet the requirements for access control of social network appropriately. Firstly, the paper elaborates syntax, semantics and evaluation algorithm of Active-UD-Datalog, which is a distributed updatable datalog with active rules and triggering mechanism we develop for the model. Secondly, access control model DUD_RuleSN for Social Network is introduced and the authorization framework is explained. Finally, a motivational example and a contrastive analysis are discussed.
