The CPU 21 reads the memory card ID registered in the PC 2 read in step P01,
The data is read from the WAP 3 and compared with the memory card ID secured in the RAM 24. If they match (step P301; Yes), then the data ID registered in the PC2 read out in step P01
Is compared with the data ID read from the WAP 3 and secured in the RAM 24. If they match (Step P302; Yes), it is determined that the authentication is successful (FIG. 5).
Step P04; Yes).

When the authentication is successful, bidirectional data transfer is enabled between the PC 2 and the WAP 3. That is, when the transfer button 103b is clicked on with a mouse, PC2 is set to

P3 transfers data such as the title, file size, file creation date and time of the music data from the ID3TAG data stored in the memory card 35 to the PC2 in response to the request signal. PC2, as shown in FIG.
Is displayed in the WAP-side data display field 102 of the main dialog 100.

Further, according to the selection instruction input from the input unit 22, various processes such as creation, registration, or deletion of a dance character can be executed. Furthermore, when a desired file is selected from the PC-side data display field 101 and the transfer button 103a is clicked on with a mouse (step P06;
Yes), the data of the selected file is transferred to WAP3. When transferring data, the CPU 21 generates a random number to generate a data ID, registers the data ID in its own recording medium 26, transfers the data ID to the WAP 3, and writes the data ID and the multimedia data to the memory card 35 together.

The WAP 3 writes transfer data (multimedia data and data ID) to the memory card 35 in accordance with a data write request signal transmitted from the PC 2.

In the authentication process, when the memory card IDs of the PC 2 and the WAP 3 do not match, for example, the WA

o), as shown in FIG.
Warning message 109a saying "Memory card ID is different. Please initialize the memory card"
Is displayed. At the same time, "YES", "NO", "CANC"
A button for selecting whether or not to initialize, such as “EL”, is displayed.

If "YES" is selected here (step P303; Yes), the CPU 21 transmits a memory card initialization request signal to the WAP3 side to initialize the memory card 35 of the WAP3. The WAP 3 initializes the memory card 35 upon receiving the memory card initialization request signal. The PC 2 updates and registers the new memory card ID (step P304), and ends the authentication processing.

When "NO" is selected in step P303 of FIG. 6 and the memory card 35 is not initialized (step P303; NO), the data transfer from the WAP 3 is disabled, and the WAP side data of the display unit 23 is displayed. Without displaying the storage contents of the memory card 35 in the display column 102 (see FIG. 7B),
The file names of the multimedia data stored in the storage medium 26 on the C2 side are displayed in a list, and the authentication process ends (Step P04 in FIG. 5; No → Step P07).

In the authentication process shown in FIG. 6, when the memory card IDs match but the data IDs do not match (step P301; Yes → step P302; No), for example, this application is installed on a plurality of PCs 2 and each PC 2 When the same memory card ID is registered in the PC 2 and data is transferred to a plurality of WAPs 3 by each PC 2, the data ID issued by each PC 2 is different. In such a case, if the data transfer from the WAP3 side is permitted,
2 can be moved via WAP3, and illegal copying is permitted. Therefore, the authentication result is unsuccessful when connected to another PC 2.

Then, as shown in FIG. 7C, the main dialog 100 displays "Data ID is different. PC
The transfer from to the memory card will be overwritten. Memory card data cannot be transferred to a PC. Is displayed. And W from PC2 side
Only one-way data transfer to the AP 3 is enabled. WA
Transfer of ID3 TAG data and the like from the memory card 35 of P3 is disabled, and the WAP-side data display column 102 does not display the storage contents of the memory card 35. WAP from PC2
When transferring data to the WAP 3, the CPU 21 generates a random number to generate a data ID, registers the data ID on the recording medium 26, transfers the data to the WAP 3 side, stores the transferred data in the memory card 35, and ends the authentication process. .

As described above, according to the authentication system 1 of the present embodiment, when the PC 2 and the WAP 3 are connected to transfer multimedia data, the PC 2 uses the memory card ID unique to the memory card 35 provided in the WAP 3 Is acquired and registered in the storage medium 26. At the time of data transfer, a data ID for identifying the data to be transferred is issued by a random number and stored together with the memory card ID and related data. The WAP 3 stores the issued data ID and related data together with the transferred multimedia data.

When WAP3 is connected to PC2 again, PAP
The C2 side first authenticates the memory card ID, and then authenticates the data ID. Then, the data transfer function is restricted according to the authentication result, and other processes are executed and controlled.

That is, the memory card ID and data I
If D matches, PC2 and WA are regarded as authentication success.
This enables bidirectional data transfer between P3. For example, PC
2 reads out the details of the related data stored in the memory card 35 from the WAP 3 side,
Is displayed in the WAP-side data display field 102 of FIG. 7 (A).
reference).

If the memory card IDs do not match, it is recognized that a new memory card 35 has been inserted, and a warning message 109a is displayed on the display unit 23 (see FIG. 7B). Then, the memory card 35 is initialized according to the input instruction, and a new memory card ID is assigned to PC2.
The transfer of data to WAP3 is enabled only when registered with the WAP3.

When the memory card ID matches and the data I
If D does not match, data transfer from PC2 is possible, but data transfer from WAP3 is not possible.
It is assumed that detailed information of data stored in the memory card is not displayed in the AP-side data display field 102 (see FIG. 7C). W to transfer data from PC2
Overwrite the data of AP3.

Therefore, when connecting the terminals, the identification data (memory card ID) unique to the storage medium (memory card 35) provided in the data transfer destination terminal (WAP3) is registered in the transfer source terminal 2 side. And identification data issued at the time of data transfer and shared by each terminal (data I
D) and the memory card ID, an authentication process is executed, and a data transfer function can be restricted according to the result, thereby improving the reliability of the authentication and moving data between a plurality of terminals (unauthorized). Copy) can be prevented. In particular, this is effective when the same application is installed on a plurality of PCs 2 and used. That is, the memory card I
When only D is authenticated, multimedia data can be transferred between a plurality of PCs 2 via WAP 3 if all memory card IDs registered in each PC 2 are matched. According to this, when data IDs issued by the respective PCs 2 are different from each other, connection to another PC 2 results in unsuccessful authentication, and the data transfer function is limited, so that data cannot be moved and illegal copying can be prevented.
