Description

Modern businesses commonly collect and exchange vast amounts of data about customers, but such data collection and flows often remain hidden from the eyes of customers, who remain unaware of how companies collect and use their personal information. In this work-in-progress, we introduce TD-chain, a new blockchain-based system to enhance transparency of data transfers. On the one hand, TD-chain makes data flows transparent to customers; on the other hand, it provides businesses with a way to verify the quality of the data they purchase, and to establish a reputation as responsible data brokers with customers. In light of recent EU privacy regulation, our system also represents a useful tool for companies to comply with transparency, privacy-by-design, and privacy-by-default requirements for data flowing across the Atlantic.
