In this paper, we design a distributed platform for anonymized dataset trading without any centralized trusted third party. The platform consists of peers and consensus-based blockchain mechanism, and each peer acts as a data broker, data receiver, or verifier for blockchain in a data transfer transaction. A data broker collects data from data owners under their consent for data trading. The Privacy Policy Manager (PPM) manages the consent information and confirms them on behalf of data owners, when data distribution is requested from data broker. We implement a prototype system of the platform using an open-source blockchain mechanism, Hyperledger Fabric, and provide evaluation results of the prototype system.
