If the read result does not change the read-only / hidden attribute of the sound source data (1210), the electronic recording apparatus 100 executes the command corresponding to the received data packet ( 1215, a predetermined data packet including a result of performing a command corresponding to the received data packet is generated (1220), and the generated data packet is transmitted to the USB corresponding device 165 through the USB connector 135. Transmit (1225).

On the other hand, if the command corresponding to the data packet changes the read-only / hidden attribute of the sound source data (1210), the electronic recording device 100 is the USB device 165 (e.g., the USB device). In step 165, a data packet for requesting predetermined sound source application authentication data is generated and transmitted to the sound source application program that transmitted the data packet (1230).

Thereafter, the USB-compatible device 165 (eg, the sound source application program that has transmitted the data packet from the USB-compatible device 165) generates application sound authentication data for the sound source in response to the authentication data request. The electronic recording apparatus 100 transmits the data to the electronic recording apparatus 100 (1235).

Upon receiving the application authentication data for the sound source, the electronic recording apparatus 100 requests the authentication data by providing the received authentication data to the IC chip 155 (1240). The validity of the authentication data is authenticated through authentication information and an authentication program, and a predetermined authentication result information including the validity authentication result is generated and returned (1245).

According to an embodiment of the present invention, the IC chip 155 may be configured to authenticate application data authentication data for a sound source by encrypting and / or decrypting the authentication data and / or generating a predetermined OTP authentication code. It is preferable to include at least one or more things.

Thereafter, the electronic recording apparatus 100 reads the authentication result information returned from the IC chip 155 to check whether the IC chip 155 has validated the validity of the application program authentication data for the sound source (1250). ).

If the validity of the sound source application authentication data is not authenticated (1255), the electronic recording apparatus 100 generates a data packet including a predetermined authentication error result (1260), and generates the generated data packet. And transfers the USB connector 135 to the USB-compatible device 165 (1275). As a result, copyright of the sound source data stored in the electronic recording apparatus 100 is protected.

On the other hand, if the validity of the sound source application authentication data is authenticated (1255), the electronic recording apparatus 100 changes the read-only / hidden attribute of the sound source data in response to the command included in the data packet (1265). Generates a predetermined data packet including a result of performing a command corresponding to the data packet (1270), and transmits the generated data packet to the USB corresponding device 165 through the USB connector 135 (1275). ). As a result, copyright of the sound source data stored in the electronic recording apparatus 100 is protected.

According to the present invention, the sound source data stored in the memory of the electronic record is forcibly set (fixed) to the read-only / hidden property, and control is made to access only the application program authorized to access the sound source data stored in the read-only / hidden property. Thus, there is an advantage of protecting the copyright of the sound source data stored in the electronic record to a reliable level.

According to the present invention, the sound source data stored in the memory of the electronic record is forcibly set (fixed) to the read-only / hidden property, and the read-only / hidden property of the sound source data is controlled so as to access only an application for which the property change authority is authorized. By doing so, there is an advantage of protecting the copyright of the sound source data stored in the electronic record to a reliable level.

According to the present invention, a sound source output forcibly setting (fixing) sound source data stored in a memory of an electronic record to a read-only / hidden property, and reproducing sound source data stored in the electronic record with a read-only / hidden property of the sound source data By controlling not to be changed by the operating system of the device, there is an advantage that the copyright of the sound source data stored in the electronic record to a reliable level

According to the present invention, the sound source data stored in the memory of the electronic record is forcibly set (fixed) to the read-only / hidden property, and also for authenticating an application program that can access the stored music data with the read-only / hidden property. By providing a predetermined IC chip 155, there is an advantage to more highly authenticate the application program that can access the sound source data to protect the copyright of the sound source data stored in the electronic record more highly.

According to the present invention, the sound source data stored in the memory of the electronic record is forcibly set (fixed) to the read-only / hidden property, and also for authenticating an application program that can access the stored music data with the read-only / hidden property. By providing a predetermined IC chip 155, there is an advantage of protecting copyright more highly so that the read-only / hidden property of the sound source data is not changed by the operating system of the sound source output device that reproduces the sound source data stored in the electronic record. have.
