At the same time, the problem of data security is exposed during data mining. Due to there is much privacy information in the electricity marketing system, information leakage will bring huge loss to electricity company and will threaten user security, so many researches focus on the protection of data under using it normally. At present, most of the electricity companies still solve the security problem from the physical layer with authority management and firewall, but these methods are not enough in the society with highly developed information technology. This paper describes methods for electricity marketing system to ensure the safety of the database from data layer through the transformation on the original data, including data encryption and data masking. These methods reinforce the secrecy of the database by concealing sensitive information and eliminating data security risk fundamentally.
