The present application relates to the field of technology of cloud storage data security, and in particular, relates to a data control method of cloud storage. The method comprises: converting the original data by a preset method into irreversible data blocks to form a physical part of the original data, and storing it in the cloud storage data center; outputting information necessary for data restoration of the process of converting the original data to the physical part, as a logical part of the original data, and storing the logical part of the original data in an original data owner controlled storage media. In this invention, the original data to be stored is converted into the physical part, which is then stored in a cloud storage data center. The logical part of the original data required for restoring the physical part to the original data is controlled by owners of the original data. Therefore, the original data owners can control the physical part of data, which physically occupies a large space by controlling the logical part, which physically occupies a small space and therefore, control their data in a cloud storage data center.
