A New Database Tamper-Proof Operation Log System Based on Consensus Mechanism

Security issues of database management system is very crucial for the information system. The traditional relation-based database system depends on the mechanism of centric trust, where the potential security threat is the un-limited authority of the system administrator. In this paper, we deal with the problem of system operation log tamper protection by using blockchain technology. Specifically, based on the blockchain consensus, distributed storage and data encryption algorithms, a novel operation log tamper protect system is presented. It can significantly improve the security of the dbms operation logging system.
