A METHOD FOR STORING OF DATA WITHIN A CLOUD STORAGE AND A CLOUD STORAGE SYSTEM

摘要

For providing an alternative secure cloud storing of data, additionally allowing fair billing of storing data within a cloud storage, a method for storing of data within a cloud storage is claimed, wherein data of a user is stored within the cloud storage upon a request by the user. The method is characterized in that the data is encrypted, the request is directed to a managing means and - before an uploading of the encrypted data to the cloud storage - the managing means performs a deduplication on the encrypted data, so that uploading of the data is only performed, if the data is not yet stored within the cloud storage. Further, an according cloud storage system is claimed, preferably for carrying out the above mentioned method.
