Objectives
The goal of this project is to build a secure and privacy-preserving data sharing platform over public blockchain. The target system is implemented by leveraging our latest research results on advanced cryptographic encryption schemes in combination of blockchain technology. Specifically, we are going to develop a fully decentralized data sharing platform over blockchain that supports: 1) secure and robust data broadcasting to designated receivers; 2) tracing users who reveal their decryption keys; 3) preserving user's privacy (both sender and receiver); 4) keyword search. We believe that the developed system will be the first secure and full-fledged blockchain-based data sharing platform with anonymity, which is of great significance for providing a new mechanism for data sharing.
