The wide application of big data,cloud computing,artificial intelligence and other technologies has made data more centralized and the value of data enhanced,and the amount of data that organizations need to process and manage is increasing.However,the data security protection technology for these new technologies relatively falls behind,and the awareness of data security protection is weak.In addition,the propose of the current theft of data has been turned into profit,leading to increasing prominent data leakage and other security problems.On the basis of protection of data use,storage and sharing,the one-stop data security platform can provide functions such as unified authentication,authorization management,unified sensitive data standards and shared signature database through the design and deployment of six subsystems,realizing centralized information display and real-time monitoring of security components.
