| 摘 要： | 通过对已有工作的分析和对比,选用了一种利用置信因子综合局部声誉和全局声誉的信任评价机制作为研究基础,引入基于集合迭代二分法的过滤方法对推荐节点进行过滤,并提出对评价其他节点评价质量的节点的评价可信度进行了限定来提高模型的准确性和抗攻击能力.同时,为避免恶意节点用诚信买行为来掩盖恶意卖行为的情况,对买家和卖家给对方的评价...

| Abstract: | Based on analysis and comparison of the existing work,a reputation-based trust mechanism for P2P E-commerce systems which is based on local reputations and global reputations was chosen,due to its better performance.To improve the accuracy and anti-attack capability of the model,a filtering method based on the iterative dichotomy for aggregate and more comprehensive trust factors are introduced.Besides,to compute the trust value of sellers and buyers,the concept of belief factor was introduced to integrate ... |
