- the control mode is initialized and the control mode is enabled (step 3).
- the control mode is valid, data and files cannot be written to the recording device. In this case, the user can operate various application programs using the electronic computer 1.
- the user When the user writes to the recording medium, the user connects the authentication memory device 2 to the electronic computer 1 (step 4).
- the authentication USB device driver 13 that is the device driver of the authentication memory device 2 is loaded from the internal hard disk 3 and the authentication application program 14 becomes operable. .
- the authentication application program 14 is called from the authentication module 5.
- the authentication application program 14 Upon activation, the authentication application program 14 reads the second authentication data 7 from the authentication memory device 2 via a DLL program (not shown) and the authentication USB device driver 13 in response to an authentication request.

- the authentication module 5 determines the result of the authentication work of the authentication memory device 2. If the authentication status indicating the result of authentication work is “False”, it means that the authentication was successful and powerful. If the authentication status is “True”, it means that the authentication was successful.
- the authentication module 5 passes this authentication status to the data management program 4 (step 6).
- the authentication status is “False”, and the control mode remains valid because the authentication was successful. Therefore, writing to the recording device is not possible (Step 6 ⁇ 13).
- the authentication module 5 passes this authentication status to the data management program 4.
- the authentication status is “True” and the file can be taken out because the authentication was successful. At this time, the data management program 4 disables the control mode (step 7).
- the data management program 4 checks how much time has passed since the last authentication work (step 8). In the first authentication after the user connects the authentication memory device 2, the data management program 4 does not check this elapsed time. When this elapsed time t has elapsed from the predetermined set time N, the data management program 4 enables the control mode (step 8 ⁇ 12). If the elapsed time t has not elapsed from the predetermined set time N, the control mode remains invalid and a file or data is written (step 9). Once the writing is complete, other work may be done (step 10).
- the file may be continuously taken out while the control mode remains invalid (step 11 ⁇ step 8).
- the data management program 4 immediately activates the control mode (step 12). Therefore, the user data and file cannot be written to the electronic recording medium again by the recording device (step 13). In this way, the user can take out data by connecting the authentication memory device 2 to the electronic computer 1 only when he / she wants to take out the data.

- the authentication module 5 passes the authentication request to the authentication application program 14.
- the authentication application program 14 creates encrypted data using the data received from the authentication module 5 and the second authentication data received from the authentication memory device 2, and passes it to the authentication module 5.
- the authentication module 5 determines authentication by using the encrypted data received from the authentication application program 14 and the first authentication data, and sends the second authentication status back to the data management program 4 (step 25). . If the license authentication is not successful, the second authentication status “False” is sent (step 25 ⁇ 29). At this time, the control mode is valid. If the authentication is successful, the second authentication status “True” is transmitted (step 25 ⁇ 26).
