Description

TECHNICAL FIELD [0001] The present invention relates to a system and a method for providing content using a local communication medium authentication,

The present invention relates to a system and method for providing online content by authenticating a medium distributed offline using a local area communication technology.

As wired and wireless communication technologies have evolved, it has become possible to transmit and receive large amounts of data quickly. In particular, with the development of wireless communication technology, a mobile device having mobility can access a network at high speed while moving. Further, as the integration degree of the processor is increased, the device is miniaturized and the processing performance is improved.

Recently, a mobile device (e.g., a smart phone, etc.) has been introduced that can communicate with a network at high speed while moving, process large amounts of data, or execute application programs.

As communication performance of a mobile device has been improved and high speed transmission and reception of large amount of data has become possible, a method of distributing an application program or multimedia contents that can be executed or reproduced in a device through a wired / wireless communication network has been introduced. This approach has been widely adopted especially in the purchase of applications or content via mobile devices.

For example, a service platform provider may provide an "application (content) marketplace" through which a developer, a content provider, and a user of the device can access through the network, To the application (content) market, where the user of the device accesses the application (content) market and downloads or executes or plays the application or content he or she needs, free of charge or at a predetermined price, Content) ecosystem "was established.

In general, a user of a mobile device may download an application or content free of charge, such as paying a certain price (e.g., watching an advertisement, making a payment, etc.). The developer or the content provider may receive some or all of the amount paid by the user for the downloaded application program or content, or pay a fee from a third party (e.g., the number of times the user has viewed the advertisement from the advertiser, In proportion to advertising revenue, etc.). Service platform providers charge transaction fees for applications or content that are traded in the application market, or earn revenue by collecting a portion of advertising revenue from third parties. Examples of these "application (content) ecosystems" include Apple Inc.'s Appstore, Google Inc.'s Google Play Store, SK Telecom's T Store, and KT's OleMarket.

The transaction of the application program or the content through the above-described application ecosystem is widely used for content transaction of a mobile device (e.g., a smart phone) due to the simplicity of downloading, etc., In this case, an appropriate e-commerce platform is provided to the user. In the case of transactions of applications or contents through the application ecosystem, payment means such as card settlement or online money settlement is used rather than cash settlement due to the characteristics of the e-commerce platform.

In the case of such a payment means, payment is completed online, and the user can process the download, execution, and result process of the desired content or application program online. However, for users who are not familiar with online e-commerce platforms, payment methods can be difficult. In addition, since the distribution path of the application program and the content is monopolized by the service platform provider that has created the application ecosystem, the fee charged by the service platform provider is set to be excessively high, which may shrink the transaction.

Meanwhile, a mobile device generally includes various types of Near Field Communication (NFC) modules in addition to a wireless communication module and a processor. Such a short-range communication module can be configured based on RFID (Radio Frequency Identification) technology, and can communicate with an external device having an active or passive RFID module at a short distance.

The client device 100 may communicate with the server 200 via a wired and / or wireless network. The client device 100 can download the corresponding application program from the server 200 using the unique codes received from the NFC medium 500 and download the contents (multimedia data) from the server, Lt; RTI ID = 0.0 > multimedia data < / RTI >

In reproducing the content data provided from the server 200, the client device 100 may adjust the output ratio of the accompaniment sound source and the voice sound source according to the ratio set by the user on the application.

To this end, the content data provided from the server 200 is divided into an accompaniment sound source and a voice sound source in case of sound source data, and the separated data is provided to the client device 100.

In addition, the client device 100 may further include a sound source input module. The sound source input module may be a microphone provided in a mobile terminal. In this case, the client device outputs the sound source data among the content data, and simultaneously generates the user-created sound source by merging the sound source data and the external input sound.

That is, after the user removes the output of the voice sound source and sets only the accompaniment sound source to be output in the sound source output, if the user inputs a song with his / her upbringing along with the sound source output, .

Of course, it is also possible to weakly set the output of the voice source so as to generate a user-created sound source including a user's voice in chorus form.

The client device 100 stores the generated user-created sound source in the terminal or transmits the generated sound source to the server 200 to be described later. In this case, transmitting the user-created sound source to the server 200 is for uploading the user-created sound source to the user's social network in which the server 200 is already set.

Of course, in this case, the account information of the social network for the user is stored in the server, and a process of setting up automatic upload by the user is required.

Meanwhile, the server 200 may include a database storing downloadable application programs (applications) and contents (multimedia data, etc.). Of course, in this case, the application program and the content data are separately stored corresponding to the unique code so as to be distinguished from the unique code stored in the NFC medium.

The server 200 may communicate with the client device 100 over a wired network and / or over a wireless network. The server 200 may receive at least one of a unique code of an NFC medium, an application program download request message, and an application program enable message from the client device 100 via a wired / wireless network.

Meanwhile, the content provider 300 can upload an application program and contents to be sold by the content provider to the server 300.

The server 200 may store a unique code of the NFC medium 500 and a matching list of the client device 100 corresponding thereto. When a user of the client device 100 wants to execute or reproduce an application program or contents corresponding to the NFC medium 500 in one or more client devices 100 with one NFC medium 500, A predetermined number of client devices 100 can be registered with respect to one NFC medium 500.

For example, when the client device 100 transmits an application enable request message including the unique code of the client device 100 and the unique code of the NFC medium 500 obtained via the local communication, Can check whether the unique code of the client device 100 and the unique code of the NFC medium 500 exist in a pre-stored matching list, and transmit an application program enable message based thereon.

The content provider 300 may be a developer of an application program or a producer of multimedia content. The content provider 300 can upload an application program developed by the content provider 300 or multimedia content created by the content provider 300 or a combination thereof to the server 200. The content provider 300 records the code for allowing the client device 100 to download the content provided by the client device 100 from the server 200 and to reproduce or execute the content on the NFC medium 500 and store the code in the offline store 400 It can be sold through. The content provider 300 may receive at least a part of the sales proceeds of the NFC medium 500 sold through the off-line store 400 as proceeds.

The offline store 400 may sell the NFC medium 500. The offline store 400 receives the NFC medium 500 from the content provider 300 or an intermediate merchant and can sell the NFC medium 500 through offline payment. The offline store 400 can sell an intermediate margin to the user of the client device 100 by attaching an intermediate margin to the NFC medium 500. The off-line store 400 may be provided with a promotional device (not shown) for introducing the contents of an application program and / or multimedia data that can be enabled through the NFC medium 500 being sold.

The NFC medium 500 may include an active, semi-passive, passive RFID module as the medium including the NFC module. For example, the NFC medium 500 may be configured in the form of an RFID card. The NFC medium 500 may be provided with a unique code and may transmit the unique code to the NFC module (not shown) of the client device 100 through short-range communication.

The unique code assigned to the NFC medium 500 can be encrypted and stored. The unique code stored in the NFC medium 500 is used when the application program or the content is downloaded from the server 200 in the client device 100 or when an application program installed in the client device 100 is enabled, .

The NFC media 500 may also store information about the UFI that represents the download path so that the application or content may be downloaded for the first time from the client device 100. [ For example, the client device 100 receives the unique code and URI information of the NFC medium from the NFC medium 500 and displays the URI corresponding to the URI information to the user, so that the user can simply The application program and / or contents corresponding to the NFC medium 500 may be downloaded.

Meanwhile, the content provider 300 may upload the content or application program to the server 200, and may allow the user of the client device 100 to download the content or application program afterwards. At the same time, the content provider 300 decides to sell the application program and / or the content registered in the server offline, and can directly produce or commission the NFC medium 500. The NFC medium 500 may be uniquely set to the NFC medium 500 corresponding to the application program and / or the contents uploaded by the content provider 300 to the server. The unique code of the NFC medium 500 may correspond to an application program and / or content created by the content provider 300.

The NFC medium 500 may be sold to the user via the offline store 400. In the offline store 400, the NFC medium 500 can be sold through offline payment (i.e., an offline purchase method such as cash settlement or card settlement). While the NFC medium is distributed in the off-line store, the NFC medium 500 may be packaged and distributed in its own distribution case so that the unique code stored in the NFC medium 500 is not read until the final sale time.

The user removes the application program and / or contents uploaded by the content provider 300 from the server (e. G., The client device 100) by removing the NFC medium 500 purchased through offline settlement, 200). The client device 100 may include an installation guide program that facilitates content marketing via the NFC media 500 that is distributed offline. The application program guide program is transmitted from the server 200 to the NFC medium 500 through the operation of simply placing the client device 100 in contact with or proximity to the NFC medium 500 without any special operation by the user of the client device 100. [ Or contents to be downloaded and installed corresponding to the inherent code of the application program and / or the content.

For example, the application installation guide program may identify the unique code received via the NFC media 500, control the application download limit setting of the client device 100, and automatically register the corresponding application and / Or contents can be downloaded from the server 200 and installed in the client device 100. [

If the application program installation guide program is not installed in the client device 100, the user can download the application program and / or the content from the server 200 manually. For this purpose, a guide message may be written in the distribution container of the NFC medium to guide how to download the application program and / or contents from the server 200 manually. The client device 100 may display the application download URI corresponding to the unique code of the NFC medal 500 so that the user can download the application program by simply clicking on the URI.

Hereinafter, a content providing method using the local communication medium authentication according to the present invention will be described in detail with reference to the accompanying drawings.

First, various embodiments in which an application is downloaded and installed in a client device in a content providing method through authentication of a local communication medium according to the present invention will be described.

As shown in FIG. 2, the client device 100 receives a message from the server 100 only once at the time of installing the application program (S165) Thereafter, the content or application program can be enabled only by reading the NFC medium 500 without communicating with the server 100.

The client device 100 can read the unique code of the NFC medium from the NFC medium 500 via the short distance communication (S110). A process of enabling the client device 100 to download the content application program (or multimedia content) or enable the playback of the content application program (or multimedia content) when the unique code is read from the NFC medium 500 .

When the client device 100 reads the unique code of the NFC medium 500 via the short distance communication, the client device 100 transmits a content application program corresponding to the unique code of the NFC medium 500 in the client device 100 (Or whether the multimedia contents are stored) (S120).

If the content application program is not installed, the client device 100 may determine whether the content application program installation guide program for downloading and installing the content application program is installed in the client device 100 (S130) .

When the content application program installation guide program is installed in the client device 100, the client device 100 can execute the content application program installation guide program (S140). The content application program installation guide program stored in the client device 100 allows the client device 100 to download an application program corresponding to the unique code received from the NFC medium 500 from the server 200. [

To this end, the content application program installation guide program may have a right to control some options of the client device 100. For example, if the client device 100 has a limited option to install only applications purchased through an online application market, the content application installation guide program may have the authority to release the restriction options.

The client device 100 can download and install an application program from the server 200. [ When the application program guide program is executed (S140), the application program guide program may cause the client device 100 to download and install the application program (S150).

The client device 100 transmits the unique code of the received NFC medium 500 and the unique code of the client device 100 to the server 200 when the content application is first downloaded (and / or installed) (S160).

The server 200 examines the unique code of the NFC medium 500 received from the client device 100 and the unique code of the client device 100 at the time of downloading or installing the first application program, / You can send a rejection message.

The client device 100 may receive an NFC unique code registration permission message from the server 200 (S165). When the client device 100 receives the NFC unique code registration permit message in step S165, the client device 100 stores the matching of the unique code of the NFC medium 500 and the unique code of the client device 100 in a memory (S170).

Once the client device 100 downloads or installs the application program, the client device 100 may enable the application program without communicating with the server 200 (S180). For example, the client device 100 reads a unique code from the NFC medium 500 (S110), and when an installed content application program is searched (S120), the client device 100 reads the unique code from the NFC medium 500 The inherent code and the unique code of the read NFC medium 500 can be compared (S171).

Here, if the unique code of the NFC medium matched with the previously installed content application program coincides with the unique code of the read NFC medium 500, the client device 100 enables the downloaded (installed) content application program (S180). Otherwise, the client device 100 may disable the content application and terminate the process.

Since the client device 100 does not need to communicate with the server 200 for authentication of the NFC medium 500, even if the communication with the server 200 is not smooth, .

3, if the content application program installation guide program is not installed in the client device 100, the client device 100 may provide the URI related to the download of the content application program to the user S240). To this end, the NFC medium 500 may include information about a download URI and a command for the client device 100 to launch a browser to provide the download URI to the user.

At this time, the content data transmitted from and stored in the server 200 may include sound source data and image data, as described above. The sound source data is for sound output when the application is enabled, and the image data is a portion for video output such as 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 client device will be described. The second embodiment of application installation of the client device performs steps 110 to 150 as in the first embodiment of the application installation of the client device do.

Thereafter, the client device 100 may match the received NFC code with the downloaded application program and store it (S360). Accordingly, when the NFC specific code is read from the NFC medium 500 in the future, the client device 100 can automatically enable the content application program to be matched.

The client device 100 may also transmit the received NFC unique code and the unique code of the client device to the server 200 (S370). In this case, the server 200 may match the received NFC unique code and the unique code of the client device and store the unique code in the database. The server 200 matches and registers the unique code of the client device with the corresponding NFC unique code, and the contents application program enable request message including the NFC unique code matched from the client device 100 and the unique code of the client device Only when it is received can the enable operation of the application be permitted.

The client device 100 may enable the downloaded content application program (S380). The client device 100 enables the content application program, which may mean that the application program is executed in the client device 100. [ Or when the downloaded data is multimedia content corresponding to the unique code of the NFC medium 500, enabling the content application program by the client device 100 means that the corresponding multimedia content is reproduced in the client device 100 It can mean.

The client device 100 can 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 client device 100 may mean prohibiting execution or playback of the application program and / or multimedia content. In this case, in order to enable the content application program again, the unique code of the NFC medium 500 may be received from the NFC medium 500 through the short-range communication.

On the other hand, when the content application program is already installed, upon receiving the unique code of the NFC medium 500, the client device 100 transmits the received NFC unique code and the unique code of the client device 100 to the server 200 (S371). The received NFC unique code and the unique code of the client device 100 may be included in the application enable request message and transmitted.

When receiving the application program enable message from the server 200, the client device 100 may enable the downloaded content application program (S371).

If the content application program installation guide program is not currently installed in the client device 100, the client device 100 may provide the URI related to the download of the content application program to the user (S440). To this end, the NFC medium 500 may include information about a download URI and a command for the client device 100 to launch a browser to provide the download URI to the user.

Commands stored in the NFC medium 500 and information on download URIs may include a command for communicating with the server 200 to download a content application program, download URI information for downloading a content application program, and the like .

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 a server 200 according to an embodiment of the present invention. Is a separate server independent of the application market server that constitutes the existing application program ecosystem.

Figure 4 is a flow diagram illustrating the step of allowing unique code registration of an NFC medium in a client device, performed in a server according to an embodiment of the present invention.

4, the server 200 may match and store the unique code of the received NFC medium 500 and the unique code of the client device 100 (S570). The server 200 matches and stores the unique code of the received NFC medium 500 and the unique code of the client device 100 in step S570 and transmits the NFC medium unique code registration permission message in step S550 as follows .

The server 200 may allow the client device 100 to download the content application program (S510).

After the application program is downloaded, the server 200 first receives the unique code of the NFC medium 500 and the unique code of the client device 100 (S520) and receives the same NFC medium 500 from the database (not shown) It is possible to confirm whether or not the inherent code of the terminal is stored (S530).

In one embodiment, once the NFC media 500 is produced, the unique code of the produced NFC media 500 may be stored in the server 300 in a batch before distribution. The unique code of the NFC medium 500 stored in the server 200 is stored as a valid unique code and can be used to determine whether the distributed NFC medium 500 is illegally copied or not.

In one embodiment, when the server 200 stores the unique code of the created NFC medium 500 in the database, the server 200 stores the unique code of the received NFC medium 500, It can be determined whether or not it is included in the inherent code of the medium 500 (S525). When the unique code of the received NFC medium 500 is matched with the stored unique code list, the server 200 determines that the unique code of the received NFC medium 500 is valid, and proceeds to the next step S530 .

If the unique code of the received NFC medium 500 does not match the stored unique code list, the server 500 may stop the execution of the steps S530 or S580 and terminate the method. Optionally, the server 200 may send an application program disable message to the client device 100.

When the unique code of the NFC medium 500 received from the client device 100 is already stored in the server 200, the server 200 stores the unique code of the other client devices matched to the unique code of the stored NFC medium 500 The unique code of the client device 100 received from the client device 100 may be compared (S540).

If the unique code received from the client device 100 is included in the unique code list of the client device matched with the unique code of the stored NFC medium 500 in the server 200, To transmit an NFC unique code registration (allow) message.

If the inherent code received from the client device 100 is not included in the unique code list of the client device matched to the unique code of the stored NFC medium 500 in the server 200, The unique code of the NFC medium 100 may be matched to the unique code of the corresponding NFC medium 500 and stored in the NFC medium 500 in operation S570. Here, the server 200 may further determine whether the number of unique codes of the client device matched to the unique code of the stored NFC medium 500 exceeds a preset threshold value (S560).

When the number of unique codes of the client device matched with the unique code of the stored NFC medium 500 exceeds a predetermined threshold value, the server 200 adds a new code to the unique code of the corresponding NFC medium 500 Reject the unique device code matching of the client device 100, and transmit an NFC unique code registration (reject) message (S580).

Accordingly, the content provider 300 can control the content or application program distributed through the NFC medium 500 to be reproduced or executed only by a predetermined number of client devices.

When the unique code received from the client device 100 is included in the unique code list of the client device matched with the unique code of the stored NFC medium 500 in the server 200, An acceptance message can be transmitted (S550). This may be the case where the client device 100 receives the first downloaded application and then re-downloads it.

If the unique code of the NFC medium 500 received from the client device 100 is not already stored in the server 200, the server 200 transmits the unique code of the received client device 100 to the corresponding NFC medium 500, (S570), and transmits the NFC unique code registration (allow) message to the client device 100 (S550).

4, the server 200 matches the unique code of the client device 100 with the unique code of the NFC medium 500 at the time of initial registration, stores the unique code in the client device 100 ), And may transmit an enable allow (deny) message to the client device 100 in response thereto.

However, when the client device 100 registers the unique code of the client device 100 and the unique code of the NFC medium 500 in its own memory at the time of installing the first application program, the client device 100, And may not exchange messages with the server 200.

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

FIG. 5 is a flowchart illustrating a method of outputting content data of a client device according to an embodiment of the present invention.

As shown in FIG. 5, when an application program is enabled in the client device, the application program reproduces (outputs) content data corresponding to the NFC medium specific code.

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

Meanwhile, the client device outputs the sound source and the image according to the set output mode, and activates / deactivates the sound input module (S620, S630, S640).

When the voice input module is activated, the voice output unit and the voice input unit input through the voice input module are merged to generate and store a user-created voice input source.

If a user command is input during the execution of steps 620 to 640, the application is controlled according to the contents of the user command (S660).

That is, if the input user command is an output mode change command, the output mode is determined by determining the changed output mode, and if the input user command is an application end command, the application is terminated.

At this time, the stored user-created sound source may be transmitted to the server (S670). This is for uploading the user-created sound source to a user's social network server already established through the server, or for sharing and storing the user-created sound source.

Meanwhile, in the present invention, the user-created sound source may be expanded from a sound source file to be a moving picture file.

At this time, the client device 100 includes an image input module. At this time, the image input module may be a camera module installed in the mobile terminal. 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 generated user-created sound source may be transmitted to the server 200 and registered in the user account of the YouTube or SNS as UCC.

Meanwhile, the server 200 may classify and store various user-generated sound sources transmitted from the client devices 100 into the same music title. And it is possible to provide the user-created sound sources generated by others to the user who transmitted the user-created sound source for the same music.

In this way, users can compare the user-created sound sources generated by others with respect to the same music as themselves to cause fun and competition among the fans of the same music (same music number).

It is to be understood that the invention is not limited to the embodiments described herein but is defined by the scope of the claims and that various changes and modifications can be made within the scope of the claims It is self-evident.

The present invention relates to a system and method for providing online content by authenticating a medium distributed offline using a local area communication technology. According to the present invention, an application program for a client device By extending the sales path offline, there is an advantage that a variety of distribution channels can be provided to consumers of the application program.
