Abstract

The increase in use of Smart mobile devices has allowed for an ever growing market for services providers. These services are increasingly used to connect to users' on-line private information through social networking sites that share and personalise on-line information. This leads to the problem of privacy leaks stemming from an application's non-adherence to a predefined set of privacy policies. This paper presents a formal methods tool to reliably restrict the access to content in on-line social network services. The Poporo tool builds upon a previous work in which we provided a predicate calculus definition for social networking in B that models social-network content, privacy policies, and social-network friendship relations. This paper presents the implementation and the functionality of our Poporo tool through a running example in the domain of social networking sites.
