摘要	In the cloud storage model, user need to confirm the file status while it's kept in the untrusted remote storage server. Then user could decide to restore the data or use the data for other purpose. By pre-random sampling from a file to form samples and sign them, provide users with a credible certification credentials. When user initiates a verification, the storage server re-generate a new signature in accordance with the same rules. By comparing the signatures, user can verify whether the file is complete. Analysis showed that, with this random sampling method, user can find file corruption with quite high probability. though a single verification may be not quite provable, user can send multiple challenge to get better credibility. Also, time required for verification has nothing to do with file size , but the credibility of the verification. Experimental results show that this schema work better under cloud storage model than other schema based on signatures and has a very high credibility.; In the cloud storage model, user need to confirm the file status while it's kept in the untrusted remote storage server.
