Analysis and Research on the Big Data Security Based on Cloud Platform

Objective: The purpose of this paper is to build a large data security encryption model in the cloud, which can make users to upload and download data more reliable. Model: This paper uses the data security storage model to analyze the security model of the cloud big data. Process: We used the mathematical code, and storage the cloud big data into the memory, then, the code information is composed of element equation, each memory is unable to obtain the code, so to achieve the purpose of encryption and protection of data. Conclusion: Cloud technology and big data security is still in its infancy, which is the trend of future development, this paper provides a theoretical reference for the security encryption mode and it has a great significance.
