Under the background of the construction of the digital power grid and the accelerated development of the energy Internet

the amount of data in the power industry has increased explosively

and the risk of data leakage has intensified. It is urgent to ensure the safety of the whole life cycle of data through data desensitization technology. This paper focuses on the data desensitization technology in the power industry

analyzes the characteristics and security needs of power data

expounds the principles and advantages of common data desensitization technology

discusses its application practice in the safe storage

transmission and sharing of power data

puts forward the challenges faced by current technology application and gives countermeasures and strategies

aiming to provide theoretical and practical reference for improving the level of data security protection in the power industry.
