The abstract of the patent published by the U.S. Patent and Trademark Office states: “A server receives a request to upload a file form a user device. The server may generate a unique file ID associated with the file based on the request, and transmit the file ID to the user device. The user device may divide the file to generate multiple slice files and their corresponding slice IDs. From the user device, the server receives the multiple slice files and the slice IDs. Based on the slice IDs, the server may determine storage addresses at which to store the multiple slice files in a distributed storage system using a consistent hash algorithm. The multiple slice files may be stored based on the corresponding storage addresses of the distrusted storage system.“

The patent application was filed on May 31, 2012 (13/576,213).
