Research on Cloud Computing Data Differential Privacy Protection Algorithm on 5G Network Environment

To solve the problem of poor differential privacy protection in cloud computing environment caused by the complexity and uncertainty factors of 5G network environment, this article studies the differential privacy protection algorithm for cloud computing data in 5G network environment. Establish a differential privacy protection architecture for cloud computing data in 5G network environment, use information entropy suppression method to eliminate redundant data in cloud computing environment, and treat cloud computing data in 5G network environment as a community. In addition, Laplace noise is added to the data within the community. By reconstructing the edges within the community and between communities, the differential privacy of cloud computing data in 5G network environment is protected. Experimental results show that after eliminating redundant data and implementing differential privacy protection, the maximum reduction of data structure complexity is 1.2, and the information leakage ratio is significantly reduced, indicating that this research method has a significant application effect.
