SYSTEM AND METHOD TO PROTECT DATA PRIVACY OF LIGHTWEIGHT DEVICES USING BLOCKCHAIN AND MULTI-PARTY COMPUTATION

摘要

Described is a system for improving data privacy in Internet of Things (IoT) devices. The system includes an IoT device having data stored thereon, one or more blockchain nodes in communication with the IoT device, and one or more multi-party computation (MPC) nodes in communication with the IoT device and the one or more blockchain nodes. The data is encrypted using a blockchain process, and a symmetric key for the encrypted data is securely distributed via a MPC process to a data recipient.
