Had the problem of not having.

Further, when the portable information terminal is used, the user can manage the data only within the capacity of the data recording medium mounted on the portable information terminal, and there is no free capacity of the data recording medium. When newly storing data, there is a problem that other data already stored must be discarded to secure a free space.

The present invention has been made to solve the above problems, and manages data handled by a portable information terminal without imposing a burden on the user so that the user can use the portable information when using the portable information terminal. An object of the present invention is to provide a data management method and a data management system capable of increasing the data storage area used via a terminal.

[0008]

In order to solve the above-mentioned problems, a data management method and a data management system of the present invention are provided by a user or another portable information terminal or server via the wireless transmission path to the portable information terminal. When an access accompanied by data transfer to the mobile information terminal is detected, a short-distance wireless transmission path different from the wireless transmission path is used to establish communication between the portable information terminal and the portable data management device. Data is transferred between the portable data management devices according to the access.

Further, during a period in which there is no access accompanied by data transfer from the user or another portable information terminal or server via the wireless transmission path to the portable information terminal, the portable data management device is put into a low power consumption operation state. When the access is detected, the portable data management device is set to the normal operation state.

Identification information unique to each of the plurality of portable information terminals is registered in the portable data management device, and authentication of the identification information is transferred between the portable information terminal and the portable data management device. The condition is set as follows.

Further, when data is stored in the portable data management device, identification information unique to the portable information terminal is stored as file information of the data, and the portable information terminal requesting access to the stored data is stored. Identification information,
The access to the stored data from the portable information terminal is permitted when the identification information of the file information of the stored data requested to be accessed matches.

Therefore, according to the present invention, data management that protects and manages the data handled by the portable information terminal without imposing a burden on the user and can increase the data storage area used by the user through the portable information terminal. A method and data management system can be provided.
