1. A data synchronization method comprising:

  • transmitting from a master device to a slave device a certificate indicating that the slave device belongs to a data synchronization group to which the master device belongs and a priority to be used for solving conflict of data, thereby registering the slave device as a member of the data synchronization group to which the master device belongs; and

    determining whether or not a first slave device and a second slave device which is capable of communicating with the first slave device belong to the same data synchronization group by using the certificate, and performing data synchronization between the first slave device and the second slave device based on the priority if the first slave device and the second slave device belong the same data synchronization group.
