Li, Ming, Bonti, Alessio and Zhou, Wanlei 2010, OST : A transaction based online social trust model for social network and file sharing security, in IEEE/IFIP 2010 : Proceedings of the IEEE/IFIP 8th International Conference Embedded and Ubiquitous Computing 2010, IEEE, Piscataway, N.J., pp. 826-832.
The continuous growth of the users pool of Social Networking web sites such as Facebook and MySpace, and their incessant augmentation of services and capabilities will in the future, meet and compare in contrast with today's Content distribution Networks (CDN) and Peer-to-Peer File sharing applications such as Kazaa and BitTorrent, but how can these two main streams applications, that already encounter their own security problems cope with the combined issues, trust for Social Networks, content and index poisoning in CDN? We will address the problems of Social Trust and File Sharing with an overlay level of trust model based on social activity and transactions, this can be an answer to enable users to increase the reliability of their online social life and also enhance the content distribution and create a better file sharing example. The aim of this research is to lower the risk of malicious activity on a given Social Network by applying a correlated trust model, to guarantee the validity of someone's identity, privacy and trustfulness in sharing content.
