Evaluating Cloud Users’ Credibility of Providing Subjective Assessment or Objective Assessment for Cloud Services

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8831)

Abstract

This paper proposes a novel model for evaluating cloud users’ credibility of providing subjective assessment or objective assessment for cloud services. In contrast to prior studies, cloud users in our model are divided into two classes, i.e., ordinary cloud consumers providing subjective assessments and professional testing parties providing objective assessments. By analyzing and comparing subjective assessments and objective assessments of cloud services, our proposed model can not only effectively evaluate the trustworthiness of cloud consumers and reputations of testing parties on how truthfully they assess cloud services, but also resist user collusion to some extent. The experimental results demonstrate that our model significantly outperforms existing work in both the evaluation of users’ credibility and the resistance of user collusion.
