GAO Feng1, HE Jing-sha2
The existing trust based on privacy protection methods simply map the trust rank to privacy sensitive grade which cannot express the dynamic and contextdepend characteristic of trust and privacy information. In order to solve this problem, an information flow model based on trust is proposed, and the model is reasonable and secure by analysis. Using this new model and also by controlling the access granularity of privacy information, a privacy protection method is proposed which can use trust to protect privacy effectively and safely.
