  • System and method for remote storage auditing
    Patent number: 9893896
    Abstract: The present invention relates to remote storage auditing. In another embodiment, a remote storage auditing system may include a first remote storage manager configured to be a data owner, a second remote storage manager configured to be a storage donor, and a remote storage auditor. The first remote storage manager sends a data block and a signed fingerprint for the data block to the second remote storage manager. The second remote storage manager verifies that the signed fingerprint is associated with the data block and stores the data block and signed fingerprint. The second remote storage manager calculates a fingerprint for a sub-block of the data block, and sends the fingerprint for the sub-block and signed fingerprint to the remote storage auditor. The remote storage auditor audits a sub-block of the data block and verifies the fingerprint for the sub-block and signed fingerprint.
