We are developing a trust framework for social networks. The framework includes new metrics for trust evaluation and its confidence. We consider trust assessments similar to physical measurements. Therefore, we apply measurement theory of errors in trust evaluation. We have tested our framework with real datasets from social networks. Our results confirm the validity of our approach. Furthermore, we show some great advantages of our framework, for example the trust view in an experiment was increased more than 2000 times. Our framework can be used to build security mechanisms for social networks, including filters against DDoS and untrusted information, detection of cliques of attackers and much more.
