This paper presents Droplet, a decentralized data access control service, which operates without intermediate trust entities. Droplet enables data owners to securely and selectively share their data, while guaranteeing data confidentiality against unauthorized parties. Droplet handles time series data, and features a cryptographically-enforced fine-grained and scalable access control for encrypted data streams. In this paper, we present Droplet's design, the reference implementation of Droplet, and experimental results of three case-study apps atop of Droplet: Fitbit activity tracker, Ava health tracker, and ECOviz smart meter dashboard.
