ABSTRACT
This chapter introduces the user behavior authentication scheme. It describes the method for user behavior trust level prediction. The user behaviour security management user behavior authentication security management behavior authentication set is personalized and critical to ensuring the accuracy of behavioral authentication. In addition to calculating the prior probability, the conditional probability of each behavioral certification set level is also required. The chapter examines the Bayesian network is used to analyze the weight information of user behavior attributes, and analyses the decision method is used to calculate the user trust level. It discusses the user behavior authentication process of the remote sensing cloud service based on a Bayesian network, and combines Bayesian network inference technology to solve the problem of user behavior trust level. Remote sensing cloud service is based on cloud computing technology, which packages remote sensing data, information products, processing algorithm technology and computing resources into measurable services.
