communication circuitry configured to request the plurality of cloud storages to store the respective file fragments of the plurality of file fragments.

2. The device of claim 1, wherein the file stored in the device is received from one among the plurality of cloud storages.

3. The device of claim 1, wherein the processing circuitry is further configured to determine, from among the plurality of cloud storages, two or more cloud storages in which to store a first file fragment from among the plurality of file fragments, and

wherein the communication circuitry is further configured to request each of the two or more cloud storages to store the first file fragment.

4. The device of claim 1, wherein the communication circuitry is further configured to request at least one among the plurality of cloud storages to store file split information, the file split information comprising identification information of the plurality of file fragments and identification information of the plurality of cloud storages storing the plurality of file fragments.

5. The device of claim 1, wherein the processing circuitry is further configured to encrypt the file based on an encryption key, to generate the plurality of file fragments by splitting the encrypted file, and to store the encryption key in at least one of the device or in at least one among the plurality of cloud storages.

6. The device of claim 1, wherein the processing circuitry is further configured to generate the plurality of file fragments by splitting the file, to encrypt one or more file fragments among the plurality of file fragments based on an encryption key, and to store the encryption key in at least one of the device or in at least one among the plurality of cloud storages, and

wherein the communication circuitry is further configured to request the plurality of cloud storages to store respective file fragments of the plurality of file fragments comprising the two or more encrypted file fragments.

7. The device of claim 1, wherein, when respective file fragments of the plurality of file fragments are stored in respective cloud storages of the plurality of cloud storages, and the processing circuitry is further configured to delete the file stored in the device.

8. The device of claim 1, wherein the file stored in the device is also stored in a cloud storage from among the plurality of cloud storages, and

wherein the communication circuitry is further configured to request the cloud storage storing the file to delete the file.

9. A device comprising:

processing circuitry configured to determine a plurality of cloud storages for storing respective file fragments of a plurality of file fragments split from a file; and

communication circuitry configured to receive the plurality of file fragments from the plurality of cloud storages,

wherein the processing circuitry is further configured to regenerate the file by merging the plurality of file fragments, and to execute the regenerated file.

10. The device of claim 9, wherein the communication circuitry is further configured to receive, from at least one among the plurality of cloud storages, file split information comprising identification information of the plurality of file fragments and identification information of the plurality of cloud storages storing the plurality of file fragments, and

wherein the processing circuitry is further configured to determine, based on the file split information, the plurality of cloud storages storing the respective plurality of file fragments.

11. The device of claim 9, wherein a first file fragment from among the plurality of file fragments is stored in two or more cloud storages from among the plurality of cloud storages,

wherein the processing circuitry is further configured to select one from among the two or more cloud storages in correspondence to the first file fragment, and

wherein the communication circuitry is further configured to receive the first file fragment from the selected cloud storage.

12. The device of claim 9, wherein a second file fragment from among the plurality of file fragments is stored in two or more cloud storages from among the plurality of cloud storages, and

wherein the communication circuitry is further configured to receive different portions of the second file fragment from the two or more cloud storages.

13. A method of storing a file, the method comprising:

generating a plurality of file fragments by splitting the file stored in a device;

determining a plurality of cloud storages used to store respective file fragments of the plurality of file fragments, wherein the plurality of cloud storages are selected from among cloud storages in which a user of the device is registered; and
