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