A Preliminary Study on Data Security Technology in Big Data Cloud Computing Environment

In the rapid development of Internet technology, the application of various new technologies has become more and more extensive. Among them, the development of big data technology and cloud computing technology is very rapid, and these technologies are of great help to improving the efficiency of data storage and management. However, the data system itself has certain data security problems in the big data cloud computing environment. In order to improve people's information security in the process of data processing and integration, we need to study data security protection technology in the big data cloud computing environment. Only in this way can we solve data and information security issues based on specific conditions and improve the reliability and security of data transmission.
