A privacy-preserve method of creating file directory of cloud storage system

摘要

To preserve privacy has been a difficult problem in designing secure cloud storage system. In existing cloud storage systems, the privacy protection of user file directories is ignored while the privacy protection of files is focused on. A privacy-preserving method of creation file directory in cloud storage systems is proposed in this paper. This method makes cloud service providers can't identify the file directory of any user which is stored on cloud servers. It also solves the consistency of the directory tree file storage through client memory caching file directory and solves the integrity of the storage through keeping up the atomicity of directory tree file operations.
