Secure computer file storage system and method
A computer file storage system and method are provided. The system and method include means for separating a file into components, encrypting each of those components and storing them on different cloud storage systems. Suitable security steps are provided to effect the encryption and access to the file components. When retrieval of the file is desired, the system will find the various file components and decrypt the components and reassemble them into the original file format.
1. A method of securely storing a file, the method comprising:
selecting a file for storage;
separating the file into a plurality of blocks using a computer system;
sending each of the blocks to separate selected servers on a cloud system with at least one of the blocks being sent to a server on each of a plurality of cloud systems providing redundant storage therefor;
showing a user's available storage space on each of the cloud systems prior to said sending;
encrypting each of the blocks and creating at least one security device for each said block to limit access to each said block;
creating an identifier for each block as to its storage location and its position in the file relative to at least one other said block;
storing said blocks each on the respective selected server;
requesting recall of each of the blocks utilizing a security device; and
having a programmed computer system decrypt the recalled blocks and reassemble the decrypted blocks into the original file.
2. The method of claim 1 wherein said security device including a plurality of keys operable to effect decryption of a respective said block.
3. The method of claim 2 wherein said keys include a public key and a private key.
4. The method of claim 1 wherein the separating of the file into a plurality of blocks is accomplished in accordance with an algorithm programmed into the computer system.
5. The method of claim 4 wherein the computer system is part of the cloud system.
6. The method of claim 4 wherein the separating of the file is accomplished randomly.
7. The method of claim 2 wherein the security device includes at least one password operable to selectively provide access to the cloud system.
