This also applies to other embodiments described later. FIG. 6 is a flowchart showing the characteristic operation on the server computer 1 side. First, when the setting registration for arbitrarily setting the contents of the application / data setting table 8 is instructed (step A1), the name of the AP software / database to be set in the application / data setting table 8 is selected. At the same time, the terminal name of the portable terminal 2 that is permitted to access the AP software / database is selected (step A3). Then, when the name of the selected AP software / database is written in the application / data setting table 8, the terminal ID corresponding to the selected terminal name is acquired from the terminal registration table 7,
The terminal ID is written in the application / data setting table 8 in association with the AP software / database name (step A4). After the data for one record is set in the application / data setting table 8 in this manner, it is checked whether the setting end is instructed (step A5), and the above-described operation is repeated until the setting end is instructed (step A5). A2
~ A4).

Next, when the writing to the CF card 3 is instructed (step A6), the CF card 3 is set on condition that the CF card 3 is set in the card reader / writer 4 (step A7). Move on to write processing to.
First, the write type is selected (step A8).
Here, when the user selects and specifies writing to the CF card 3 corresponding to the terminal or writing to the CF card 3 corresponding to the terminal group, the selected writing format is determined. Now, when the writing corresponding to the terminal is selected and designated, the CF set in the card reader / writer 4 is set.
Read the "medium number" from the card 3 (step A
9), The terminal ID corresponding to the medium number is acquired from the terminal registration table 7 (step A10). Then, the application / data setting table 8 is searched based on the terminal ID, and the terminal I
The name of the AP software / database corresponding to D is acquired, and the AP software storage unit 5 and the database storage unit 6 are acquired accordingly.
The corresponding AP software / database is read from (step A11). Now, in the application / data setting table 8 shown in FIG. 4B, if the terminal ID is “ID11”, the corresponding AP software is “α1”, and the database “D1” is the AP software storage unit 5, the database. It is read from the storage unit 6.

A corresponding to the terminal ID obtained in this way
The P software / database is written in the CF card 3 (step A12), and the terminal ID obtained in step A10 is written as access control information for the AP software / database (step A1).
3). When such writing is completed, a "writing flag" indicating that the writing has been completed is set in the application / data setting table 8 corresponding to the terminal ID (step A14). When a plurality of CF cards 3 are set in the card reader / writer 4, unwritten C
It is checked whether the F card 3 is present (step A15), and if there is, the process returns to step A9, the next CF card 3 is accessed to read the "medium number", and the same writing to the CF card 3 is performed as described above. Perform processing. As a result, when the writing is completed for all the CF cards 3 in the set, the application / data setting table 8 is referred to, and the terminal ID for which the "write flag" is not set is extracted and corresponds to this terminal ID. The terminal name is acquired from the terminal registration table 7, and a list of unwritten terminal names is displayed (step A16), and a writing completion message is displayed and output (step A17).

On the other hand, when the writing corresponding to the CF card 3 corresponding to the terminal group is selected and designated, a terminal group name selection screen is displayed, and a desired group name is selected and designated from the selection screen (step A18). The group registration table 9 is searched based on this group name, and a plurality of corresponding terminal IDs are acquired (step A19). Then, the contents of the application / data setting table 8 are searched from the top based on the plurality of terminal IDs, and the terminal I
If even one D is included, the corresponding AP software / database is read from the AP software storage unit 5 and the database storage unit 6 (step A20). Here, when the terminal group A is selected, the AP software “α
1 ”is acquired. Then, the acquired AP software / database is written in the CF card 3 together with the corresponding terminal ID (steps A21 and A22). In this case, AP
Software "α1" and terminal IDs "ID11" and "ID12"
And are written in the CF card 3 in association with each other. Then, the jiu-jitsu operation is repeated until the same writing is completed for all the CF cards 3 set in the card reader / writer 4 (steps A21 to A23).
When writing to all media is completed by this, step A
Proceed to step 24, and unwritten AP in the same group
Software / database is application data setting table 8
If there is, the process returns to step A20. If so, "α2" is read as AP software corresponding to the terminal group A, and is written in each CF card 3 together with the terminal ID "ID13". . Hereinafter, similarly, the database “D1” and the terminal ID “ID11” are assigned to each CF card 3
Written in, then in the database "D2", terminal ID
"ID12", database "D3", terminal ID
“ID13” is written in each CF card 3. As a result, the contents of each CF card 3 corresponding to the terminal group A become as shown in FIG. 2B, and when all the writing corresponding to the terminal group A is completed, the writing completion message is displayed (step A17). The CF card 3 in which the AP software / database has been written in this way
It is distributed to the corresponding portable terminal 2 side.

FIG. 7 is a flowchart showing the operation on the side of the mobile terminal 2, which is started when the power is turned on. First, when an arbitrary AP software / database is selected from the initial menu screen and its activation access is instructed (step B1), the CF card 3 is added to the mobile terminal 2.
If is not set (step B2), the process returns to step B1 to invalidate the activation access, but C
If the F card 3 is set, the preset terminal ID of its own is read (step B3). And
The CF card 3 is accessed and the terminal ID stored therein is read (step B4), and it is checked whether or not it matches the terminal ID of itself (step B5). In this case, since the CF card 3 corresponding to the group also stores the other terminal IDs belonging to the group for each AP software / database, the terminal ID corresponding to the selected AP software / database is sent from the CF card 3. It is read and it is checked whether or not its own terminal ID is included therein. Here, if a match of the terminal IDs is detected, access to the AP software / database selected and designated on the condition is permitted, and the process shifts to execution (step B).
6) If a mismatch of the terminal IDs is detected, the process returns to step B1, so that access to the AP software / database is prohibited.

As described above, in the first embodiment,
When the AP software / database in the CF card 3 is accessed for data processing, the mobile terminal 2 uses the CF card 3
The terminal ID read from the terminal is compared with the preset own terminal ID, and the access / control to the AP software / database in the CF card 3 is controlled by the matching / mismatching. Only the AP software / database in the CF card 3 can be accessed. That is, the mobile terminal 2 that can access the AP software / database in the CF card 3
Since it is possible to control the access for each terminal, it is possible to effectively prohibit illegal copy and duplication by another mobile terminal 2 that does not have access authority. This is not limited to the CF card 3 corresponding to the terminal, but the same applies to the CF card 3 corresponding to the group. When using a specific AP software / database for each business area, if the terminal group is divided for each area. It is possible to control access for each terminal group. In addition, the terminal I is associated with each AP software / database in the CF card 3.
When D is stored, its access can be controlled for each terminal and each AP software / database. That is, when a plurality of AP software / databases are stored in the CF card 3, access to a specific AP software / database is permitted, but access to other AP software / databases is prohibited. Even if the mobile terminals 2 belong to the same terminal group, the access can be controlled for each AP software / database.

On the other hand, the server computer 1 writes AP software / database in the CF card 3 to write AP software / database to the portable terminal 2 side via the CF card 3.
The database is distributed, but at this time, the server computer 1 has the terminal ID associated with this CF card 3.
Is read and the terminal ID is written in the CF card 3 together with the AP software / database.
Mobile terminal 2 that allows access to software / database
Can be specified. As a result, access control can be performed for each terminal, and illegal copy and duplication by another mobile terminal 2 that does not have access authority can be effectively prohibited. Further, the server computer 1 refers to the application / data setting table 8 that defines the terminal to which the access is permitted for each individual AP software / database, thereby writing the AP software / database for each CF card 3 corresponding to the terminal. Can be specified. This applies not only to the CF card 3 corresponding to the terminal but also to the CF card 3 corresponding to the group. By writing the terminal ID of each mobile terminal 2 belonging to the same terminal group into the CF card 3, the AP software / It is possible to specify the terminal group that is permitted to access the database, and this enables access control for each terminal group.

Although the CF card is shown as a portable storage medium in the above-described first embodiment, the present invention is not limited to this, and a magnetic or optical recording medium, a semiconductor memory or the like may be used, and a card type card may be used. It is not limited to this, and may be a cartridge type disk or the like. The client terminal is not limited to the mobile type portable terminal 2 and may be a desktop type terminal. Furthermore, the terminal ID for prohibiting the access is not limited to the case of writing the terminal ID for permitting the access corresponding to the AP software / database in the recording medium.
May be written.
