In order to allow users can always verify the integrity of the data stored in cloud storage server,this paper proposed a dynamic data integrity verifying method based on homomorphic tags.Users could infinitely verify whether data integrity intact by introducing a homomorphic tags and user randomly selected data blocks to be verified,and support data dynamic updating;trusted third party auditor(TPA) could solve disputes of data integrity between users and cloud storage provider to realize the public validation of the data;and analysed correctness,security and performance of this method;finally the proposed method that could detect cloud storage data integrity was verified by experiment.
