摘　　要：针对Web用户信息的安全问题,提出了一种主客观相结合的用户行为信任评估模型.通过熵权法确定客观权重,通过层次分析法确定主观权重,进一步得到优化的集成权重.通过引入基于滑动窗口的长期量化评估机制和对不同类型证据的无量纲化处理,最终计算出用户行为的信任评估值.实际应用和理论分析结果表明,该模型在满足主、客观相对平衡的优化条件下,可以更准确地得出单次和长期用户行为的信任评估值,对诸如电子商务、网络金融等关键网络应用用户行为的高可靠性判断奠定了坚实的理论和实践基础.Aiming at the safety problem of the web user information,proposed a subjective and objective method of user behavior trust evaluation model. Using the entropy-weight-method to calculate the objective weight and analytic-hierarchy-process to determine the subjective weight,then combining the previous two results to further calculate the integrated weights with optimal balance,also introduced long-term quantitative evaluation mechanism based on the Sliding Window. Finally,through the dimensionless treatment of various type evidences and get the final user-behavior trust evaluation value. The theoretical analysis and practical application show that the model can meet the subjective and objective relative balance optimization conditions,and can get more accurate user behavior trust evaluation value for each-time and long-time interaction. It lays the solid foundation of theory and practice for high reliable analysis of user behavior in key network application such as e-commerce and online bank.
