Decentralized Authorization for Encrypted Data Streams
The moment we upload our data into the Internet, we give the ownership of our data.
Applications trade with user data without their consent.
There is no need to give up data ownership, to use innovative services!
Few cooperations control majority of data in the Internet.
With Droplet we intend to empower users with control over their data.
Users should decide what and with whom they want to share.
With the myriad of IoT devices, more and more Internet-connected sensors will produce personal data.
Enabling a secure storage and sharing of IoT data is imperative to its success.
How do we empower the user with ownership and fine-grained access control for IoT data without sacrificing performance or security?
We leverage the blockchain technology to bootstrap trust, for a distributed, secure, and resilient access control management.
The permission-less blockchain provides auditability to our system.
Droplet enables reliable sharing among heterogeneous applications without intermediate trust entities, and features a cryptographically-protected fine-grained and scalable access control to data streams.
Droplet handles time series data, ensuring confidentiality, integrity, and authenticity.
After defined intervals data streams become immutable, such that even compromise of secret keys does not allow modification of previous stream data.
