一种P2P电子商务系统的信誉计算模型

A COMPUTATION MODEL OF TRUSTWORTHINESS IN P2P E -COMMERCE SYSTEMS

针对P2P电子商务系统特性，提出了一种简单务实的信誉计算算法．基于用户注册信息和所列商品进行评估，给出用户的初始信誉度，分析了影响用户信誉的因素，并对其进行量化计算，从而得到用户的动态信誉计算模型．经数据分析和实验仿真，验证了计算模型的可行性和可靠性．结果表明：计算模型比现有的信任模型，能够明显提高交易的成功率和正确性，有效地应用于P2P电子商务系统中．

Based on the characters of the P2P E - commerce systems, a computation model of trustworthiness was presented. First, the initial trustworthiness was computed based on the register information and the listed products. Second, the dynamic computation model was shown by analyzing the factors that impact user＇s trustworthiness. Finall, in order to verify the feasibihty and reliability, we do the data analysis and simulation. The results showed that the presented model can improve the success rate and correctness of transactions, so it can effectively apply in P2P e-commerce systems.
