First Claim
Patent Images
1. A system for processing data, comprising:
- a first client configured to;
encrypt a first set of data;
upload the encrypted first set of data to a volume on a cloud storage system; and
create a commit record of the upload; and
a synchronization server configured to;
verify access to the volume by the first client;
include the commit record in a change set comprising a set of commit records associated with the volume;
sign the change set; and
provide the change set for use in synchronizing the upload with a second client.

Abstract
The disclosed embodiments provide a system that processes data. The system includes a first client that encrypts a first set of data, uploads the encrypted first set of data to a volume on a cloud storage system, and creates a commit record of the upload. The system also includes a synchronization server that verifies access to the volume by the first client and includes the commit record in a change set containing a set of commit records associated with the volume. The synchronization server also signs the change set and provides the change set for use in synchronizing the upload with a second client.

11. A computer-implemented method for processing data, comprising:
-
encrypting a first set of data on a first client; uploading the encrypted first set of data from the first client to a volume on a cloud storage system; creating a commit record of the upload; and providing the commit record to a synchronization server, wherein the commit record is used by the synchronization server to synchronize the upload with a second client associated with the volume. - View Dependent Claims (12, 13, 14, 15, 16)

17. A computer-implemented method for synchronizing data, comprising:
-
obtaining, from a first client, a commit record of data uploaded to a volume on a cloud storage system; using a digital signature in the commit record to verify access to the volume by the first client; including the commit record in a change set; signing the change set; and providing the change set for use in synchronizing the upload with a second client associated with the volume. - View Dependent Claims (18, 19, 20)

21. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for processing data, the method comprising:
-
encrypting a first set of data on a first client; uploading the encrypted first set of data from the first client to a volume on a cloud storage system; creating a commit record of the upload; and providing the commit record to a synchronization server, wherein the commit record is used by the synchronization server to synchronize the upload with a second client associated with the volume. - View Dependent Claims (22, 23, 24, 25)
