| 摘 要： | 目前基于信任的隐私保护方法将信任等级与隐私信息敏感等级简单进行映射以控制隐私信息的披露,所以不能反映信任和隐私信息的动态性和上下文相关性等特点。为解决此问题,提出一个基于信任的信息流模型,并分析证明了该模型是合理和安全的。结合该模型和隐私信息访问粒度控制,进一步提出了一种基于信任和信息流模型的隐私保护方法,该方法将信任运用在隐私保护中,能有效实现对隐私信息安全的保护。

| Abstract: | The existing trust based on privacy protection methods simply map the trust rank to privacy sensitive grade which cannot express the dynamic and context-depend 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... |
