Comparative study of financial and voting-based reputation systems - Experiment on feasibility of financial metric using eCommerce data sets

摘要

The reputation scoring systems play an important role in providing trust in peer-to-peer networks. Peer feedbacks and stochastic observations are the usual metrics used for the reputation score calculation. However, such metrics are fundamentally not secure against Sybil attacks and require direct discretion of the user. We propose a new metric based on the financial performance of peers indicated by the gross income parameter in order to solve this fundamental problem. In this paper, we compare this proposed metric with the regular voting-based peer feedbacks.
