PROBLEM TO BE SOLVED: To implement efficient synchronization between a server and an electronic device.SOLUTION: According to an embodiment comprises a communication processing unit, registration means, transmission processing means, and reception processing means. The communication processing unit communicates with an external device to thereby acquire second data generated based on one or more first data acquired by one or more sensors in the external device. The registration means registers the acquired second data in a first file within a non-volatile storage device, and the transmission processing means transmits third data on at least apart of the first file to a server, in which the third data includes data registered in the first file after transmitted to the server last time. The server registers the third data in a second file for registering all data transmitted from one or more second electronic devices including an electronic device dealing with a user, and has first electronic device information indicative of one or more second electronic devices. When only electronic device deals with the user, the reception processing means does not receive fourth data from the server.SELECTED DRAWING: Figure 4 |
