Databox-based Delivery Service via Blockchain

The ubiquity of sensor technology through the Internet of Things and mobile devices has led to a surge in the generation of personal data. The use of personal data to provide personalized services and optimize business decision-making has recently become a popular trend. The data marketplace is one of the most critical places where companies can source data to organize the variety of data source formats and improve individuals’ data self-management (e.g., data access control and usage). This paper proposes a Databox-based delivery service via blockchain that provides data consumers with secure and controlled access to requested data sources of interest. It consists of a databox-based data delivery module and decentralized activities service module. The former is responsible for data delivery and the latter is to provide a one-stop data sharing service on blockchain. We implement a preliminary prototype and conduct an evaluation of system activities and smart contracts utility.
