An approach for setting access control rule based on multi-party collaborative in Online Social Networks

User´s resource may involve the privacy of other users in Online Social Networks. It is the focus of the current research that how to integrate into co-workers´ willingness of privacy when setting access rule for resource. In the current research, the uploader and co-workers have same right to control sharing range of resource, so access rule of resource may threaten privacy safety of the uploader. This paper believes that resource is the carrier of privacy information, although resource involves the co-workers´ privacy, the co-workers don´t have the right of granting other users access resource, but they have the right of hiding resource. So this paper proposes an approach of setting access rule for resource based on multi-parity collaborative, that the uploader determines the user set that has the right of access resource, and the co-workers can delete some users from the user set, so this approach can ensure privacy safety of the uploader. In the process of integrating the willingness of the uploader and co-workers, we also ensure that the relationship information of them cannot be leaked to each other and the provider of Online Social Networks.
