Abstract: Different from the uniqueness and tamper resistance of traditional data, users are always facing greater risk of leakage in the data storage of cloud computing network. In order to ensure the security of users' private data, a cloud computing data privacy protection method based on blockchain is proposed. On the basis of clarifying the infrastructure of blockchain structure and cloud computing storage structure, design cloud computing data privacy protection methods. With the support of blockchain technology, based on the analytic hierarchy process model of cloud computing user privacy protection, based on the definition of blockchain messages and IPFS storage parameter settings. Cloud computing data privacy protection is realised through three parts: cloud computing data privacy disclosure path identification, cloud computing data aggregation algorithm using privacy homomorphism technology and data privacy protection algorithm based on blockchain technology. The experimental results show that the proposed method can enhance the application security of cloud computing privacy data, make it free from the risk of disclosure in the storage process and thus realise the privacy protection of cloud computing data.
