Data Security Technology and Scheme Design of Cloud Storage

Abstract

With the development of cloud storage technology, more and more users choose to store data in the cloud. Cloud storage technology saves users’ local storage space, but users lose absolute control over data, which also leads to some cloud storage data security-related issues. Based on the cloud storage application architecture, this paper provides the complete solution for cloud storage data in three ways: first, access control, prevents the intrusion of illegal users or the damage caused by the careless operation of legitimate users; second, integrity audit, ensures that the data is truly and completely stored in the cloud; third, data encryption, protects the data in network transmission and cloud storage. In the actual application process, the three technologies need to be combined to achieve the ideal data security effect.
