Abstract:
A correct reputation management system can differentiate between low-quality and high-quality data providers in an Internet of Things (IoT) data marketplace. There are challenges in designing an unbiased and secure reputation management system that can not be manipulated by wrong feedbacks or wrong aggregation of feedbacks. In this paper, we develop a decentralised reputation management system for the IoT data marketplace that prevents biased selection and aggregation of reputation feedback. The proposed reputation management system uses blockchain offline channels, which makes the solution secure, unbiased, scalable, and least costly. We prove the security and correctness of the proposed reputation management system and present its experimental evaluation using simulation of data marketplace and blockchains.
