Abstract
There is provided a data synchronization system, data synchronization method, data center, and client terminal that allow a client terminal to determine whether data held by the client terminal is up-to-date and allow synchronization between a server and the client to be maintained at low costs in a case where synchronization between data in the server and data in the client terminal is provided. The data synchronization system for keeping the sameness between data in a client terminaland data in a data serverthrough a communication link comprises a synchronization data transmitterfor sending to the client terminaldata to be kept same as data in the client terminal, a synchronization signal output modulefor sending a synchronization signal for checking the sameness to the client terminalat predetermined timing, and a synchronization signal transmission controllerfor controlling the transmission of the synchronization signal by the synchronization signal output modulebased on the result of the synchronization signal transmission by the synchronization signal output module
