Abstract

Data privacy and integrity is top of mind for modern data applications. To tackle with the above issue, we propose an encrypted database system with access control capabilities and blockchain validation in this paper. Compared to the existing encrypted database system, our design proposes a proxy-free architecture, which avoids the need for a trusted proxy for access control. In order to protect the integrity of user data, our system leverages the blockchain technology to realize a tampering protection mechanism. The mechanism ensures that modification logging is compulsory and public-available but hardened. Users can validate and easily detect the tampered data. Finally, we implement a prototype system and conduct evaluations on each component of the proposed system.
