The user terminal 100 having received the unique code from the NFC medium 50 transmits the unique code (NFC ID) of the NFC medium 50 and the unique code (i.e., the serial number of the user terminal 100) (NFC ID + USER ID), and the security code generated as shown in the following Table 1 is stored in the internal memory of the user terminal 100 (S810) .

NFC ID USER ID Generated security code 1234 a4 1234a4

The user terminal 100 transmits the security code generated in step S810 to the NFC medium 50 in step S820 and the NFC medium 50 transmits the security code received from the user terminal 100 to the NFC medium 50 50) (S830).

That is, the NFC medium 50 stores the unique code (NFC ID) stored at the time of manufacture with the security code (NFC ID + USER ID) received from the user terminal 100 and stores it.

In step S800, the user terminal 100 may receive the address information of the management server 200 from the NFC medium 50, and the user terminal 100 transmits the address information of the management server 200 to the management server 200 And transmits a content file transmission request message (S840).

The security code received from the user terminal 100 by the receiving unit 210 of the management server 200 is stored in the storage unit 230 (step S810) And the authentication unit 250 of the management server 200 authenticates the media content file transmission request based on the security code received from the user terminal 100 in the following first step authentication procedure and second Step authentication process (S850).

- Phase 1 certification -

The first step authentication is a procedure for authenticating the validity of the corresponding NFC medium 50. The first step authentication is a procedure for authenticating the validity of the corresponding NFC medium 50. The first step authentication includes a unique code (NFC ID) of the NFC medium 50 included in the security code, Is a process for judging whether or not it coincides with "

That is, when the unique code (NFC ID) of the NFC medium 50 included in the security code matches the unique code stored in the storage unit 230, the authentication unit 250 of the management server 200 , The validity of the NFC medium 50 purchased by the user is confirmed.

- Phase 2 certification -

The second stage authentication is a procedure for judging whether the number of the user terminal 100 which can download the media content file through the single NFC medium 50 is exceeded.

To this end, the storage unit 230 of the management server 200 stores the unique code of the NFC medium 50 and the number of pieces of equipment capable of downloading the media content file using the NFC medium 50 .

When the validity of the security code included in the media file transmission request received from the user terminal 100 is confirmed through the first-step authentication, the validated security code is transmitted to the management server Are stored in the storage unit 230 of the storage unit 200 in a cumulative manner.

User Terminal No NFC ID USER ID One 1234 a4 2 1234 b5 3 1234 c6

That is, when the number of user terminals 100 that can be registered in the management server 200 is three using the NFC medium 50 having the unique code "1234" as shown in Table 2, the management server 200 1234b5, and 1234c6 included in the media content file transmission request received from the user terminal 100 having the unique codes "a4", "b5", and "c6", sequentially to the storage unit 230 .

If there is a media content file transmission request from another user terminal 100 in a state where all three registered numbers are registered as shown in Table 1, the authentication unit 250 of the management server 200 adds Registration is denied, and in this case authentication for the request is not executed.

When the authentication in step S850 is completed, the transmitting unit 270 of the management server 200 transmits the media content file corresponding to the NFC ID included in the security code to the user terminal 100 (S860) The control unit 100 stores the media content file downloaded from the management server 200 in the internal memory together with the security code generated in step S810 (S870).

When the user approves the NFC medium 50 owned by the user to the user terminal 100 in order to execute the media content file stored in the user terminal 100, the NFC medium 50 (For example, "1234a4") stored as a new inherent code is transmitted to the user terminal 100 (S880).

Accordingly, the user terminal 100 determines whether or not the security code received from the NFC medium 50 is the same as the security code stored in the user terminal 100 in step S810. If it is determined that the security code is identical to the security code stored in the user terminal 100, And executes an associated media content file (S890).

As described above, according to the present invention, the media content file stored in the user terminal 100 is executed only when the user terminal 100 and the NFC media 50 are in contact with each other. Therefore, according to the present invention, The media content can be executed only when the media content is present.

Therefore, even when a media content file stored in the user terminal 100 is illegally copied to another user terminal 100, in the state where another user does not have the NFC medium 50, the illegal copy media content file is executed The illegal copying of the media content file can be substantially prevented.

In addition, according to the present invention, the user can make the NFC medium 50 contact the user terminal 100 while keeping the media content file downloaded from the management server 200 in the user terminal 100 So that users who are not familiar with the method of using the user terminal 100 such as a smart phone can easily use the media content file.

According to the present invention, since communication data is used only when a media content file is downloaded from the management server 200, there is no need to use communication data when the media content file is executed. Therefore, .

When the user deletes the media content file downloaded from the management server 200 in step S860 from the internal memory of the user terminal 100 due to careless management of the user, It is preferable that the user can download the corresponding media content file again from the management server 200 through the terminal 100. [

To this end, upon receiving the security code from the NFC medium 50 in step S880, the user terminal 100 transmits the media content file corresponding to the security code to the internal memory Or the like.

If the corresponding media content file is stored in the internal memory, the above-described step S890 is executed. If the media content file corresponding to the security code (for example, "1234a4") is not stored in the internal memory, The security code is regenerated according to the method in step S810 and the media content file transmission request message including the regenerated security code (for example, "1234a4a4 ") is transmitted to the management server 200 as in step S840 .

The management server 200 determines whether the primary security code 1234a4 included in the regenerated security code 1234a4a received from the user terminal 100 is the security Code, authenticates the media content file transmission request, and retransmits the corresponding media content file to the user terminal 100.

As described above, according to the present invention, a request to transmit a media content file from a user terminal 100 other than a predetermined number of registered user terminals 100 is blocked, By approving the retransmission request of the file, user convenience can be improved.

It is preferable that an application program for executing each of the above steps in the user terminal 100 is installed in the user terminal 100. In step S800 described above, It may be desirable to have the application program automatically run as it receives the unique code from the media 50. [

To this end, the unique code of the NFC medium 50 preferably includes app identification data (i.e., application (application) identification data) capable of identifying the application program and is provided in association with the NFC medium 50 And may further include content identification data capable of identifying the type of content.

Here, the app identification data is a criterion for judging whether or not an application program is installed in the user terminal 100, and is a criterion for requesting execution of the application program.

On the other hand, the content identification data is used to identify the type of content provided by the NFC medium 50. Specifically, the management server 200 may select a sound source and image data of a specific singer according to the content identification data, and provide the sound source and the image data to the user terminal 100.

In addition, the unique code of the NFC medium 50 may further include information related to a uniform resource identifier (URI) for downloading the content data.

Meanwhile, the user terminal 100 can download and install the application program from the management server 200 using the unique codes received from the NFC medium 50, and receive the content file (multimedia data) from the management server 200 Or may receive a message from the management server 200 that enables execution of an application program or reproduction of multimedia data.

In addition, the user terminal 100 may adjust the output ratio of the accompaniment sound source and the voice sound source according to the ratio set by the user in the application program in reproducing the content data provided from the management server 200. [

For this, the content data provided from the management server 200 is divided into an accompaniment sound source and a voice sound source in the case of the sound source data, and the separated data will be provided to the user terminal 100.

In addition, the user terminal 100 may further include a sound source input module. The sound source input module may be a microphone input module provided in the mobile terminal. In this case, the user terminal 100 outputs the sound source data among the content data and merges the sound source data and the external input sound User-created sound sources can be generated.

In other words, if the user removes the output of the sound source and sets only the accompaniment sound source to be output in the sound source output, and then inputs a song with his / her upbringing along with the sound source output, . ≪ / RTI >

Of course, it is also possible for the user to set the output of the voice sound source to be weak so that the voice of the singer can be generated in a chorus form together with the user's upbringing to generate a user-created sound source.

The user terminal 100 stores the user-created sound source in the terminal 100 or transmits it to the management server 200. In this case, the user-created sound source is transmitted to the management server 200 so that the user-created sound source can be uploaded to the social network of the user who is already set up by the management server 200.

Of course, in this case, the account information of the social network for the user is stored in the management server 200, and a process of setting up automatic upload by the user will be required. Meanwhile, the storage unit 230 of the management server 200 stores a downloadable application program (application) and a content file (multimedia data, etc.).

Meanwhile, the application program and the content data stored in the storage unit 230 of the management server 200 are separately stored in correspondence with the respective unique codes so that they can be identified from the unique codes of the NFC media 50, respectively.

In addition, the management server 200 may store a unique code of the NFC medium 50 and a matching list of the user terminal 100 corresponding thereto. When a user of the user terminal 100 wants to execute or play an application program or contents corresponding to the NFC medium 50 in one or more user terminals 100 with one NFC medium 50, The server 200 can register a predetermined number of user terminals 100 with respect to one NFC medium 50. [

Specifically, the user terminal 100 transmits to the management server 200 an application program enable request message including a unique code of the NFC medium 50 acquired through short-distance communication and a unique code of the user terminal 100 The management server 200 checks whether a unique code of the user terminal 100 and a unique code of the NFC medium 50 exist in a pre-stored matching list, and transmits an application program enable message to the user terminal 100).

In implementing the present invention, the content provider may upload an application program and contents to be sold by the content provider to the management server 200. [

On the other hand, the content provider records the code for allowing the user terminal 100 to download the content provided by the user, download it from the management server 200, reproduce or execute the content, and sell it through the offline store, The content provider receives at least a portion of the sales proceeds of the NFC media 50 sold through the offline store as proceeds.

The unique code assigned to the NFC medium 50 can be encrypted and stored and the unique code of the NFC medium 50 can be transferred from the user terminal 100 to the management server 200 When the program or the content is downloaded, the user terminal 100 can be used to enable the installed application program or to reproduce the stored content.

The NFC medium 50 may store information on a URI indicating a download path so that an application program or contents can be downloaded from the user terminal 100 for the first time.

For example, the user terminal 100 receives the unique code and URI information of the NFC medium 50 from the NFC medium 50 and displays the URI corresponding to the URI information to the user so that only the user selects the URI The application program and / or contents corresponding to the NFC medium 50 can be downloaded simply.

The NFC medium 50 is stored in the unique distribution case 50 so that the unique code stored in the NFC medium 50 is not read until the final sale time while the NFC medium 50 is distributed in the offline store, And the like.

In addition, in implementing the present invention, the user terminal 100 may be provided with an installation guide program for facilitating the sale of content through the NFC medium 50 distributed offline.

Such an application program guide program is transmitted from the management server 200 to the NFC medium 50 only by the operation of placing the user terminal 100 and the NFC medium 50 in contact with or close to each other without any special operation by the user of the user terminal 100. [ And perform an operation of controlling the application program and / or the content corresponding to the unique code of the medium 50 to be downloaded and installed.

For example, the application installation guide program can identify the unique code received via the NFC media 50, control the application download limit setting of the user terminal 100, and automatically register the corresponding application and / Or contents can be downloaded from the management server 200 and installed in the user terminal 100.

If the application program installation guide program is not installed in the user terminal 100, the user can download the application program and / or the content from the management server 200 manually.

For this, a guide message may be written in the distribution container of the NFC medium 50 to guide the user how to manually download the application program and / or contents from the management server 200.

The user terminal 100 may display an application download URI corresponding to the unique code of the NFC medium 50 so that the user can download the application program by simply clicking on the URI.

Hereinafter, various embodiments for downloading and installing an application from the user terminal 100 will be described.

As shown in FIG. 2, the user terminal 100 receives a message from the management server 200 only once when installing an application program, (S165). Thereafter, the content or the application program can be enabled only by reading the NFC medium 50 without communicating with the management server 200. [

When the user terminal 100 reads the unique code of the NFC medium 50 from the NFC medium 50 via the short distance communication at step S110, the user terminal 100 enables the download of the content application program (or the multimedia content) Or a process of enabling playback of the execution of the content application program (or the multimedia content) may be performed.

When the user terminal 100 reads the unique code of the NFC medium 50 via the short distance communication, the user terminal 100 installs a content application program corresponding to the unique code of the NFC medium 50 in the user terminal 100 (Or whether or not the multimedia contents are stored) (S120).

If the content application program is not installed in the user terminal 100, the user terminal 100 determines whether or not the content application program installation guide program for performing downloading and installation of the content application program is installed in the user terminal 100 (S130).

When the content application program installation guide program is installed in the user terminal 100, the user terminal 100 executes the content application program installation guide program (S140).

The content application program installation guide program installed in the user terminal 100 allows the user terminal 100 to download an application program corresponding to the unique code received from the NFC medium 50 from the management server 200. [

For this, the content application program installation guide program may have a right to control some options of the user terminal 100. For example, if the user terminal 100 has a limited option to install only applications purchased through the online application market, the content application installation guide program may be authorized to release the restriction options.

When the application program guide program is executed (S140), the application program guide program causes the user terminal 100 to download and install the application program (S150).

The user terminal 100 transmits the unique code of the NFC medium 50 and the unique code of the user terminal 100 to the management server 200 when the content application program is first downloaded and installed in the user terminal 100 S160).

The management server 200 examines the unique code of the NFC medium 50 received from the user terminal 100 and the unique code of the user terminal 100 at the time of downloading the first application program, A message or a reject message may be transmitted.

When the user terminal 100 receives the NFC unique code registration permission message from the management server 200 in step S165, the user terminal 100 transmits the unique code of the NFC medium 50 and the unique code of the user terminal 100 Is stored in the internal memory (S170).

Once the user terminal 100 downloads or installs the application program, the user terminal 100 can enable the application program without communicating with the management server 200 (S180).

For example, the user terminal 100 reads a unique code from the NFC medium 50 (S110), and when an installed content application program is searched (S120), the user terminal 100 reads the stored NFC medium And compares the inherent code of the NFC medium 50 with the inherent code of the read NFC medium 50 (S171).

Here, if the unique code of the NFC medium 50 that matches the previously installed content application program coincides with the unique code of the read NFC medium 50, the user terminal 100 enables the downloaded content application program (S180). Otherwise, the user terminal 100 disables the content application program and terminates the process.

The user terminal 100 does not need to communicate with the management server 200 in order to authenticate the NFC medium 50 so that the user terminal 100 can respond to the NFC medium 50 even when communication with the management server 200 is not smooth Lt; RTI ID = 0.0 > applications. ≪ / RTI >

Meanwhile, if the content application program installation guide program is not installed in the user terminal 100, the user terminal 100 may provide the URI related to the download of the content application program to the user as shown in FIG. 3 ( S240).

To this end, the NFC medium 50 may include a command for executing a browser to allow the user terminal 100 to provide the download URI to the user, and information about the download URI.

At this time, the content data transmitted and stored from the management server 200 may include sound source data and image data, as described above. The sound source data is for audio output when the application is enabled, and the image data is for the image output such as the background screen when the application is enabled.

In addition, the sound source data may be composed of two sound source data separated by an accompaniment sound source and a voice sound source. This is to enable the user to control the output ratio of the accompaniment sound source and the voice sound source in the sound source output.

Next, a second embodiment of the application installation of the user terminal 100 will be described. The second embodiment of the application installation of the user terminal 100 is the same as the first embodiment of the application installation of the user terminal 100 Steps 110 through 150 are performed.

Then, the user terminal 100 matches and stores the downloaded application program and the NFC specific code (S360). Accordingly, when the user terminal 100 reads the NFC specific code from the NFC medium 50 at a later time, the user terminal 100 can automatically enable the matching content application program.

Then, the user terminal 100 transmits the NFC unique code and the unique code of the user terminal 100 to the management server 200 (S370). In this case, the management server 200 matches the received NFC unique code and the unique code of the user terminal 100 and stores the matching code in the database.

The management server 200 matches and registers the unique code of the user terminal 100 with the corresponding NFC unique code and stores the content including the unique code of the user terminal 100 and the NFC unique code matched from the user terminal 100 Only when an application enable request message is received, the enable operation of the application is permitted.

Accordingly, the user terminal 100 enables the downloaded content application program (S380), so that the corresponding application program is executed in the user terminal 100. [

Or when the data downloaded from the management server 200 is multimedia content corresponding to the unique code of the NFC medium 50, the user terminal 100 enables the content application program in the user terminal 100 It means that the corresponding multimedia contents are reproduced.

On the other hand, the user terminal 100 may disable the corresponding content application program when a predetermined time has elapsed or one time of playback (or execution) has ended. Disabling the content application program by the user terminal 100 means prohibiting execution or playback of the application program and / or the multimedia content.

In this case, in order to enable the content application program again, the unique code of the NFC medium 50 must be received from the NFC medium 50 through the short-range communication.

If the content application program is already installed in the user terminal 100 and the user terminal 100 receives the unique code of the NFC medium 50, the user terminal 100 transmits the received NFC unique code and the user terminal 100 ) To the management server 200 (S371).

Meanwhile, in implementing the present invention, the NFC unique code and the unique code of the user terminal 100 may be transmitted in the application program enable request message.

When the user terminal 100 receives the application program enable message from the management server 200, the user terminal 100 enables the downloaded content application program (S371).

If the content application program installation guide program is not installed in the user terminal 100, the user terminal 100 preferably provides the URI related to the download of the content application program to the user in operation S440.

To this end, the NFC media 50 should be provided with a command for the user to execute the browser to provide the download URI to the user and information about the download URI.

On the other hand, the command stored in the NFC medium 50 and the information on the download URI include a command for allowing the content application program to be downloaded by communicating with the management server 200, download URI information for downloading the content application program, do.

This is because the existing application program ecosystem has a system different from that of the command system (for example, AAR (Android Application Record)) provided by the application ecosystem system provider, which is different from the management server 200 ) May be a separate server independent of the application market management server 200 constituting the existing application program ecosystem.

4 is a flowchart illustrating a process of registering a unique code of an NFC medium in the management server 200 according to an exemplary embodiment of the present invention.

As shown in FIG. 4, the management server 200 matches and stores the unique code of the NFC medium 50 and the unique code of the user terminal 100 (S570). The management server 200 matches and stores the unique code of the received NFC medium 50 and the unique code of the user terminal 100 in step S570 and transmits a unique code registration permission message of the NFC medium 50 in step S550 The process is as follows.

When the management server 200 permits the user terminal 100 to download the content application program in step S510 and the application program is downloaded to the user terminal 100, 50 and the inherent code of the user terminal 100 are received in step S520 and whether or not the unique code of the same NFC medium 50 is stored from the storage unit 230 of the management server 200 S530).

That is, when the NFC medium 50 is produced, the unique code of the produced NFC medium 50 can be collectively stored in the management server 200 before being circulated, and the NFC medium 50 stored in the management server 200 ) Is stored as a valid unique code, and can be utilized for judging whether the circulated NFC medium 50 is illegally copied or not.

When the management server 200 stores the unique code of the NFC medium 50 in the storage unit 230 as described above, the management server 200 stores the unique code of the NFC medium 50 received from the user terminal 100, Is included in the unique code of the stored authenticated NFC medium 50 (S525).

When the unique code of the received NFC medium 50 matches the stored unique code list, the management server 200 determines that the unique code of the received NFC medium 50 is valid, and executes the next step S530 .

On the other hand, when the unique code of the received NFC medium 50 does not match the stored unique code list, the management server 200 stops the execution of the step S530 or S580, And transmits a disable message.

When the unique code of the NFC medium 50 received from the user terminal 100 is already stored in the management server 200, the management server 200 stores the unique code of the NFC medium 50, The unique code of the user terminal 100 is compared with the unique code of the user terminal 100 received from the user terminal 100 in operation S540.

When the unique code received from the user terminal 100 is included in the unique code list of the user terminal 100 matched to the unique code of the NFC medium 50 stored in the management server 200, And transmits an NFC unique code registration (allow) message to the user terminal 100 (S550).

Even if the unique code received from the user terminal 100 is not included in the unique code list of the user terminal 100 matching the unique code of the NFC medium 50 stored in the management server 200, The controller 200 may match the inherent code of the user terminal 100 to the unique code of the corresponding NFC medium 50 and store the same in operation S570 and transmit the NFC unique code registration message to the user terminal 100 S550).

Specifically, in this case, the management server 200 further determines whether the number of unique codes of the user terminal 100 matched to the unique codes of the stored NFC media 50 exceeds a predetermined threshold value (S560 ).

When the number of unique codes of the user terminal 100 matched to the unique codes of the stored NFC media 50 exceeds a predetermined threshold value, the management server 200 determines that the NFC media 50 Rejects the unique code matching of the new client device 100 and transmits an NFC unique code registration (rejection) message (S580).

If the number of unique codes of the user terminal 100 matched to the unique codes of the stored NFC media 50 does not exceed a preset threshold value, the management server 200 determines that the number of unique codes of the user terminal 100 100 in step S570 and transmits the NFC unique code registration message to the user terminal 100 in operation S550.

Accordingly, the content provider can control the content or the application program circulated through the NFC medium 50 to be reproduced or executed only by the predetermined number of user terminals 100.

Hereinafter, an embodiment in which content data is output from the user terminal 100 after an application program is enabled will be described in detail.

5 is a flowchart illustrating a method of outputting media content data in the user terminal 100 according to the present invention. 5, when the application program is enabled in the user terminal 100, the application program reproduces the content data corresponding to the unique code of the NFC medium 50. [

At this time, the user terminal 100 first determines the set output mode (S610). Here, the output mode includes the output ratio of the accompaniment sound source and the sound source in the presence or absence of the sound source output and the sound source output, and includes whether or not the image is output and whether or not the sound input mode for recording is activated.

Meanwhile, the user terminal 100 outputs sound sources and images according to the set output mode, and activates or deactivates the sound input modules (S620, S630, S640).

When the voice input module is activated, the user terminal 100 generates a user-created sound source by merging the sound sources input through the sound output unit and the sound input module, and stores the generated sound source.

If a user command is input during the execution of steps S620 through S640, the application is controlled to be driven according to the contents of the user command (S660).

That is, when the input user command is a change command of the output mode, the output mode is determined by determining the changed output mode, and when the user command is the application end command, the application is terminated. At this time, the user terminal 100 may transmit the user-created sound source to the management server 200 (S670).

This is for uploading a user-created sound source to a user's social network server that is already established through the management server 200, or for sharing and storing the user-created sound source.

Meanwhile, in the present invention, a user-created sound source may be expanded from a sound source file and produced as a moving image file. At this time, the user terminal 100 includes a video input module. At this time, the image input module may be a camera module installed in a mobile terminal such as a smart phone.

That is, as shown in FIG. 6, when the user executes the audio recording mode (Audio Rec) according to the user's selection, only the sound source input module may be activated as described above to generate a user-created sound source, When executing the video recording mode (Video Rec), the sound source input module and the image input module can be activated to generate a user-created sound source as a moving image.

The user-created sound source may be transmitted to the management server 200, and may be registered in the user account of the YouTube or SNS as the UCC. Meanwhile, the management server 200 may classify and store various user-created sound sources transmitted from the user terminals 100 into the same music name.

In addition, the management server 200 can provide user-created sound sources generated by others to the user who has transmitted the user-created sound source for the same music, Comparing the sound sources, it will be able to cause fun and competition among the fans of the same music (the same musician).
