In the cloud storage service, a Dynamic Data integrity verification method based on Homomorphic label is proposed to enable users to verify the integrity of the data stored on the cloud storage server at any time. By introducing the Homomorphic label and the user randomly selecting the data block, the data can be verified to be intact and the data is updated dynamically. The introduction of trusted third party solves the dispute of data integrity problem between cloud user and cloud storage service provider, and realizes the public verification of data integrity. The correctness and security of the method are analyzed, and the performance of the method is analyzed, and the method is proved to be efficient and feasible by experiments.
