Abstract

PROBLEM TO BE SOLVED: To provide a portable information apparatus which is capable of protecting data and ensuring secrecy in a situation in which data is being stolen or lost. SOLUTION: A situation detecting means 104 detects a situation in which a portable information apparatus is about to be stolen or the like. When the situation detecting means 104 detects such a steal or the like, processing means 101 transmits and saves important data within a storage means 102 using radio communicating means 103. If the portable information apparatus turns out to be located outside the sphere after the transmission is completed or the steal or the like is detected, the processing means 101 deletes the data within the storage means 102. Therefore, even if the portable information apparatus is stolen, as much data as possible can be saved, and after the data saving is completed, or if it turns out that the data can not be saved, the data can be deleted, thus making it possible to ensure secrecy.

Proceed to. For example, the state of the wireless communication is confirmed, and if the position of another information processing device to which the information is to be saved is out of the communication range, the process proceeds to step 614.

In step 613, if the evacuation is completed, the process proceeds to step 614. If the evacuation is in progress, the process returns to step 612.

At step 614, it is confirmed whether or not an instruction to delete important data has arrived from remote controller 702. If the PC main body 701 receives an instruction to delete important data via the wireless unit 706, the process proceeds to step 615 to delete important data. Also, if the data erasure process is set to be performed automatically without receiving the erasure instruction, the process also proceeds to step 615.

Wireless communication between the PC main body 701 of this embodiment and another information processing apparatus to which data is to be saved is a direct communication, a communication via an access point, or a communication via a wireless public line. Both configurations are possible. However, when confirming the communication state in step 612, the position of the access point is out of the service area in the case of the configuration via the access point, and is out of the service area of the base station of the wireless public line in the case of the configuration through the wireless public line. Take advantage of that. In addition, the connection between the access point and another information processing device via the access point, and the connection between the other information processing device and the public line via the wireless public line,
Both wireless and wired configurations are possible.

In the first to third embodiments described above, the GPS is used to acquire the position information.
The method of acquiring the position using the update with the base station may be used.

Although the acceleration sensor, the vibration sensor, and the tilt sensor are used, a configuration using one or two of them is also possible.

As described above in detail, according to the present invention, even if the portable information device is stolen or lost, the situation can be determined, and data protection and data saving by saving as much data as possible are possible. Erasure of security can be maintained. In addition, even if the main unit is stolen or lost while operating the main unit of the device from a remote position, such as a wireless display PC or a device with a wireless remote control, the data should be saved as much as possible. Data protection and confidentiality due to data erasure are possible.
