Research And Application Of Attribute-based Access Control Model For Multimedia Social Networks

The social network is developing rapidly and the number of users is also growing.The user can share and upload the multimedia contents rapidly,so the multimedia social networks(MSNs)users can appeal to hundreds of millions of users.The multimedia resources include pictures and video,they can be uploaded to the multimedia by a lot of users.While the social multimedia bring convenience to the user,it brought us a great challenge,because the problem of privacy and copyright disputes often occurred.How to protect the security of user information,to prevent the disclosure of user data,to achieve a more fine-grained access has become a huge challenge.Therefore,in this paper,the main research contents and innovations are as follows:However,privacy and copyright disputes have occurred frequently.How to protect the security of user information and achieve more granular access has become a huge challenge.Therefore,this paper aims at the access control problem in the multimedia social networks,the main research contents and innovations are as follows:1.This paper proposed a novel attribute-based access control model for multimedia social networks,it is established based on multi-attribute.Firstly,an attribute-based access control model called ABAC–MSN is proposed for MSNs,and the attributes of the model and the attributes under the multimedia social network are introduced.Secondly,the paper introduces the general rules of access control rules,data flow control rules and strategy conflict digestion,and we formalizes these rules.Then we list several common examples of life and description the control strategy.Finally,the ABAC-MSN is applied to the CyVOD platform,enabling secure and controllable access to media resources.2.This paper uses the ACPT tool to verify the access control policy.In order to ensure the security of the access control system,it is necessary to use a reliable method to verify whether the access control policy model conforms to the security requirements and the intention of the strategist.We use the ACPT tool to validate the proposed model strategy and generate enough test cases to detect the correctness of the model implementation.The data security problem under the social network,the privacy disclosure and the unauthorized development of audio and video become the main developmentbottleneck of the social network.This paper studies the attribute-based access control model in the multimedia social network environment.Our contribution is comprehensively to consider the attribute information in the multimedia social network platform.Based on these attributes,we propose a novel access control model to achieve more granular access and protect the security of multimedia resources,and realize the controllable transmission of copyright content.
