Remote verification of file protections for cloud data storage

摘要

A client device or other processing device comprises a file processing module, with the file processing module being operative to provide a file to a file system for encoding, to receive from the file system a proof of correct encoding of the file, and to verify the proof of correct encoding. The file system may comprise one or more servers associated with a cloud storage provider. Advantageously, one or more illustrative embodiments allow a client device to verify that its files are stored by a cloud storage provider in encrypted form or with other appropriate protections.
