Abstract:Study on behavior trust and is prospective. This paper studies trust management and behavior trust, designs trust forecast and control Algorithm based on Bayesian Networks, which can predict trust grade under the multi-trust-attribute conditions, and Clustering Arithmetic and Distribution Density Function are used synthetically to set parameters and the corresponding relationship is built between quantitive evidence and trust grade. The configurable plug-in is implemented through going deeply into IIS and .NET Framework to create the user behavior log to provide evidences for forecast and control Algorithm, which avoids data cleaning. The pratical data have shown that multiple performance are enhanced and the trade behaviors of user are restricted.
Keywords:trust management  behavior trust  Bayesian Networks  user behavior log mining
