Cloud storage is a service model in which data is maintained, managed, backed up remotely and made available to users over a network or internet. It permits the client to store files online so that the user can access them from any location via the internet. The provider company makes them available to the user online by keeping the uploaded files on an external server. A major challenge for cloud computing providers is to deliver sufficient security levels to protect users' data. A lot of research has been carried out with this target.
