摘要
与传统电子商务相比,P2P环境下的电子商务更加开放、灵活,但用户也面临更大的交易风险.为了解决P2P电子商务中的交易安全问题,提出了一种基于P2P电子商务的可信信用评价模型,它从直接信用度、推荐信用度两个维度对节点的信用进行综合评价,充分考虑了交易时间与交易金额对直接信用度的影响以及信用反馈节点的信用度对推荐信用度的影响,并对初始推荐信用值进行了修正.仿真试验结果表明,该模型可以提高信用评价的准确率,增强节点的抗风险能力.
The P2P E-commerce environment is more open and flexible than the traditional one, but so is the transaction risk. Hence,a trustworthy trust evaluation model is proposed based on P2P e-commerce, pinpointing the trust value of peer by direct and recommended trust values. The direct trust value comes from transactions in relation to timing and amount, while the recommended trust value is obtained from feedback of the peers. The original recommended trust value is amended. Result shows that the model im proves the accuracy of trust evaluation and enhances the anti-risk ability of peers.
