Sharing and synchronization of data objects between autonomously cooperating peer devices

摘要

A device for sharing and synchronizing data objects with peer devices. The device has a memory, interface for communication with a peer, and a processor. The memory is configured to store therein least one data object that is deemed either an original or a copy. When in communication with a peer device, the processor transmits a request for the peer device to send an original data object that corresponds to a data object stored in the memory if the stored data object is a copy and it is to be modified. The processor then stores the requested data object in the memory as an original data object or, if the requested data object is not received, marks the data object stored in the memory as an original. Then the processor may modify data in the original data object stored in the memory.
