<P>PROBLEM TO BE SOLVED: To provide a file protection system in which, when an earthquake occurs, a file under editing in a terminal device is automatically stored and transferred prior to the arrival of principal shock of the earthquake. <P>SOLUTION: A file protection system has an earthquake information distribution server 2 and a plurality of client terminals 4. The earthquake information distribution server 2 receives an earthquake early warning distributed from an earthquake early warning distribution server 1, calculates a seismic intensity predicted value and a principal shock arrival predicted time, and performs broadcast communication of earthquake information having the seismic intensity predicted value and the principal shock arrival predicted time via a communication network 3. Each of the plurality of client terminals 4 is connected to the earthquake information distribution server 2 via the communication network 3, uses an application program under execution and an application program to specify a file under editing when the broadcast communication of the earthquake information is performed from the earthquake information distribution server 2, and uses a forced store command corresponding to the application program to store and transfer the file under editing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
