Abstract: If the energy and power data are illegally exported or tampered with，national security will be seriously
threatened. Taking the database with energy and power characteristic from North China Electric Power University for
example，the current situation and existing problems of database management are analyzed. Based on the consortium
blockchain technology，a technical solution with dual authentication for the database and users' identity information is
proposed. This solution can strengthen information security certification，improve the security factor of the database，and
protect the rights of data contributors. Based on the anti-tampering and traceability of the blockchain technology，the
traceability management model and procedure for the energy and power database are put forward.Taking Hash algorithm to
obtain anti-counterfeit labels for documents and recording them in the block can provide credible evidence for the safety
supervision and traceability of the document，and can effectively prevent energy and power data from being tampered with
by malicious visitors. Solutions and ideas for efficient supervision and secured sharing of energy and power databases are
provided.

Key words: blockchain, database, dual authentication, traceability, Hash algorithm
