As cloud computing continues to grow, an increasing amount of sensitive data is migrated to the cloud for storage and processing. However, sensitive data is usually stored in a single cloud environment, which poses several risks such as data leakage and a single point of failure. To address the above issues, a security verification system based on bilinear maps in the multi-cloud environment (i.e. SVS-BM) is proposed. In the paper, bilinear mapping technology is used to ensure the integrity and authenticity of user data during transmission and processing in the multi-cloud. Moreover, trusted middleware connects the terminal to multiple cloud service providers, which ensures efficient management and security verification of user data by segmenting and merging user data. Experimental results and performance analysis show that the system can effectively guarantee user data integrity and security in the multi-cloud environment.
