Abstract
As the value of the big data is revealed, the problem of security prevention and control of customer service data is highlighted. Once the leakage of sensitive customer information will cause serious legal consequences. At present, State Grid Corporation has effectively resisted the risk of data collection, storage, and transmission through internal and external network isolation and data encryption. However, at the data application level, due to frequent data sharing and business collaboration, new risks of leakage continue to emerge in data mining, data interaction between systems, terminal data access, etc. This article first analyzes the risks faced by data security in terminal data access, cross-domain data transfer, and open data sharing. Then, it proposes terminal data access behavior management and control technology, data cross-domain transfer security interaction technology, and data differentiated privacy protection technology in open sharing. Finally, t on the basis of technical research, the core equipment of data protection was developed and tested, and verified the effectiveness of the technology in practice.
