[ For example, an authentication version or an authentication number identified from the authentication data through the output interface unit 370, and the user of the portable terminal 300 (agent manager or dealer) And may receive the result of the selection through the input interface 360. [0050] FIG.

There may be a number of versions to be updated here, and the version to be updated may be a version based on the received authentication data, i. E., Among successively subsequent versions in the authenticated version of the authentication data. The version that can be renewed can also be changed according to the authentication token data currently stored in the portable terminal 300. Even if multiple versions can be selected by one update, if the number of authentication token data is small, To be selected.

Of course, in this case, the user of the portable terminal 300 may log into the authentication server 100 and charge the authentication token data further.

The authentication data update program can be implemented so that the control data including the selected specific authentication data or enabling the authentication data to be recognized is encrypted and transmitted to the song accompaniment device 400. [

By allowing the authentication data of the song accompaniment device 400 to be managed and updated as described above, it is possible to conveniently update the authentication data to the song accompaniment device 400 and to eliminate the inconvenience of updating the authentication data to the dealer or dealer .

The control flow for updating the authentication data using the portable terminal 300 will be described in further detail with reference to FIGS. 4 and 5. FIG.

First, the authentication token generating apparatus 200 logs in (① in FIG. 4) using an account (using a user identifier and a password, etc.) registered in the authentication server 100 of a designated address by using HTTP (Hyper Text Transfer Protocol) do.

The distributor manager or dealer of the authentication token generating apparatus 200 can confirm the entire authentication token data currently stored in the virtual account of the authentication server 100 according to the login. If there is no authentication token data or less than the required number, the dealer manager or the dealer can purchase additional authentication token data (② in FIG. 4) using the dealer manager or dealer's financial server with the account number.

4 and 5, which are shown between the authentication token generating apparatus 200 and the authentication server 100, may be performed by the portable terminal 300. [ The portable terminal 300 may be a portable terminal 300 registered in advance in the authentication server 100 with respect to a specific agent or a dealer.

Accordingly, the authentication server 100 updates the entire authentication token data of the virtual account corresponding to the registered account of the authentication token DB 110 so as to reflect the purchased additional authentication token data ((3 in Fig. 4)).

The manager or dealer of the agent having the portable terminal 300 can log in to the authentication server 100 using the portable terminal 300 (in this case, the same as ① in Fig. 4) (4 & cir & in Fig. 4).

The portable terminal 300 may also transmit its own identifier to the authentication server 100 and the authentication server 100 may register the portable terminal 300 registered with the virtual account in which the portable terminal 300 is registered ). If the terminal is not registered, this information may be transmitted to the portable terminal 300 to prevent further access to the authentication token DB 110.

This cryptographic session may involve generating an encryption key and a decryption key and may be accomplished by any particular promised encryption algorithm. The administrator of the portable terminal 300 confirms the current total authentication token data stored in the connected virtual account through the output interface unit 370 of the portable terminal 300 and notifies the portable terminal 300 of the authentication token data (360).

The portable terminal 300 requests authentication token data to be charged to the authentication server 100 and downloads the authentication token data according to the downloaded authentication token data in step 5 in FIG. 4 and stores the authentication token data in the storage unit 380 or the security module 340 ⑦ of 4). The authentication token data downloaded here may be encrypted with an encryption key different from the encryption session set up and may be stored as an encryption key using the identifier of the portable terminal 300, for example. Alternatively, the security module 340 may encrypt the downloaded authentication token data using the identifier of the portable terminal 300.

Then, the authentication server 100 updates the authentication token DB 110 according to the download of the authentication token data ((6) in FIG. 4).

Here, the authentication server 100 updates the entire authentication token data of the corresponding virtual account by reflecting the downloaded authentication token data. The authentication token data for the portable terminal 300 registered for the virtual account is updated by reflecting the downloaded authentication token data. In this process, the authentication server 100 can request the authentication token data currently stored in the portable terminal 300 before the download of the authentication token data, and accordingly, store the actually stored authentication token data of the portable terminal 300 in the authentication server 100).

4, the authentication server 100 can easily download an authentication token or the like purchased by a dealer or a dealer to the portable terminal 300, and then, using the portable terminal 300, It is possible to conveniently update the display 400.

5 is a diagram showing an embodiment of a control flow for updating the authentication data of the song accompaniment device 400 from the portable terminal 300. As shown in Fig.

This control flow preferably occurs between the processor 390 or the security module 340 of the portable terminal 300 and the control unit 480 of the song accompaniment device 400, The control flow generated between the control unit 480 and the authentication data processing unit 490 will be described with reference to the control flow of FIG.

The control unit of the song accompaniment device 400 may be operated according to a connection request of the portable terminal 300 to the song accompaniment device 400 or in response to a request for connection to the portable terminal 300 through the input unit 410 of the song accompaniment device 400. [ The portable terminal 480 and the portable terminal 300 set up a communication channel of a local area network for transmitting and receiving data between the two devices and set an encryption session for encrypting data to be transmitted and received (1 in FIG. 5).

The control unit 480 of the song accompaniment device 400 connected to the processor 390 of the portable terminal 300 or the security module 340 determines an encryption method and an encryption key and a decryption key to be used for encryption and decryption. The encryption key, the decryption key, and the encryption method may be driven by the portable terminal 300.

The processor 390 or the security module 340 of the portable terminal 300 transmits the encryption and decryption algorithm stored in the memory of the storage unit 380 or the security module 340 of the portable terminal 300, To the control unit 480 of the song accompaniment device 400.

Accordingly, the control unit 480 eliminates the need to store a specific encryption algorithm or the like in the nonvolatile memory 450 or the hard disk 470, and accordingly, more secure data transmission / reception is performed.

During or before the setting of the encryption session, the song accompaniment device 400 may transmit the identifier of the song accompaniment device 400 or the current time to the portable terminal 300. [ The identifier or the current time of the song accompaniment device 400, the identifier of the portable terminal 300 and the current time recognized by the portable terminal 300 can be used as a parameter for generating an encryption key and a decryption key, , It is possible to generate different encryption keys and decryption keys at each connection.

In this connection, it is possible to encrypt control data that can be updated via Wi-Fi communication, for example, using different encryption keys, and this control data is used for authentication data to be updated from the authentication data stored in the song accompaniment device 400 Such as the number of authentication tokens, such as the difference value (e.g., the difference value between versions or numbers). This control data enables the control unit 480 of the song accompaniment device 400 to update the authentication data.

The portable terminal 300 can further transmit a request for updating the song accompaniment device 400 including the identifiers of the portable terminal 300 and the song accompaniment device 400 to the authentication server 100 have. In this case, the portable terminal 300 may additionally log in using the identifier of the dealer or dealer.

Upon receiving the update request, the authentication server 100 determines whether the identifier of the portable terminal 300 and the song accompaniment device 400 stored in the authentication token DB 110 are managed by the same agency or dealer, And transmits an update permission or an unrecognized response to the portable terminal 300 (3 in Fig. 5).

Of course, steps (2) and (3) of FIG. 5 may be omitted depending on the embodiment.

The portable terminal 300 receives the authentication data stored in the authentication data processing unit 490 of the song accompaniment device 400 from the song accompaniment device 400 (step 4 in FIG. 5). Of course, such data may be encrypted since it is data transmitted and received after the encryption session.

The portable terminal 300 converts the received authentication data into a form for the manager or dealer of the agency to recognize and outputs the authentication data through the output interface unit 370. The authentication token Information such as a subsequent version that can be updated from the authentication data based on the data is also outputted ([5] in FIG. 5) through the output interface unit 370.

The information thus output can be identified, for example, by year and month, or can be identified in the form of a number. Subsequent versions output here may also be defined according to the value of the authentication token data and, in addition, limited according to the range of predetermined versions that can be updated at one time.

Then, the portable terminal 300 receives a specific version or specific number from the user through the input interface 360, generates control data to be transmitted to the song accompaniment device 400 according to the received input data, The control data capable of identifying the data is encrypted through the encryption session and transmitted to the song accompaniment device 400 ((6) in FIG. 5).

Such control data may indicate, for example, the number of authentication numbers to be updated, the number of authentication versions to be updated, or the number of consecutive versions that can identify subsequent authentication data to be updated from the stored authentication data (Number of) authentication tokens.

The control unit 480 of the song accompaniment apparatus 400 decrypts the encrypted control data received via the interface unit 440 and transmits the decrypted control data to the song accompaniment apparatus 400, Updating the authentication data stored in the authentication data processing unit 490 using the designated control command with the authentication data processing unit 490 so that the authentication data is updated from the control data to one authentication version limited among the plurality of authentication versions that can be updated by the authentication data processing unit 490 (7) in Fig. 5).

Here, the control unit 480 and the authentication data processing unit 490 of the song accompaniment apparatus 400 can also transmit data using the encryption key and the decryption key designated to each other, and in particular, The control unit 480 of the authentication server 400 can further encrypt and store it in the authentication data processing unit 490. [

Therefore, since the authentication data stored in the authentication data processing unit 490 is encrypted, even if the authentication data is hacked, this information can not be known. Here, the encryption for the authentication data may be performed based on the current time at which the song accompaniment device 400 updates, for example, by using the identifier of the song accompaniment device 400 or in addition. Accordingly, the current time can be further stored in the nonvolatile memory 450 of the song accompaniment device 400. [

The control unit 480 of the song accompaniment apparatus 400 reads the updated authentication data stored in the authentication data processing unit 490 to determine whether the update has succeeded or failed and includes the success failure judgment. The log data such as the identifier of the device 400, the previous authentication data, the updated authentication data, the update time, and the like are encrypted and transmitted to the portable terminal 300 (⑧ in FIG. 5).

The processor 390 or the security module 340 of the portable terminal 300 decrypts the received log data and transmits authentication token data (9 in FIG. 5) stored in the portable terminal 300, . Such an update may be updated by the control data transmitted in the previous ⑥ of FIG. 5 as well.

The portable terminal 300 transmits a synchronization request including the log data received from the song accompaniment device 400 and the updated authentication token data (or the number of updated authentication tokens) to the portable terminal 300, including the identifier of the portable terminal 300 To the authentication server 100 (10 in Fig. 5).

Accordingly, the authentication server 100 can update the received authentication token data in the authentication token DB 110 using the identifier of the portable terminal 300 in real time, and also store log data in the corresponding song accompaniment device 400 have. When the authentication token data of the portable terminal 300 has already been changed in the authentication token DB 110, the authentication server 100 transmits authentication token data reflecting the authentication token data to the authentication token DB 110, (300).

Of course, this synchronization process may occur whenever the authentication token data corresponding to the portable terminal 300 stored in the authentication token DB 110 of the portable terminal 300 and / or the authentication server 100 is changed.

5, authentication data such as an authentication version or an authentication number of the song accompaniment device 400 can be conveniently updated using the portable terminal 300, Authentication token data can be synchronized in real time.

5, the authentication data to be directly updated is transmitted and received between the portable terminal 300 and the song accompaniment device 400 using the local area network.

It is not necessary to directly transmit the control data of the song accompaniment device 400 to the portable terminal 300 if the song accompaniment device 400 is connected to the authentication server 100 via the broadband network Alternatively, the portable terminal 300 may request the authentication server 100 to update the authentication data, and the authentication server 100 may directly transmit the authentication data to be updated in the song accompaniment device 400 in the form of data to a specific item have.
