It may include. In addition, the user information, the terminal information, the identification information of the NFC card may be configured in one set.

For example, the first tagged terminal 100_1 may provide the user ID A1, the device ID B1 of the tagged device, and the NFC card identification information (NFC ID) C1 to the content providing server 300. In this case, the content providing server 300 may configure the A1, B1, and C1 as a set, and configure the A1, B1, and C1 in a table form as shown in FIG. 21 to store the data in the database 400.

As such, after the process of registering the specific terminal 100_1 specific NFC card 10, if the specific NFC card 10 is tagged again to the specific terminal 100_1, the content providing server 300 is a predetermined After only the authentication process, the content corresponding to the tagged NFC card 10 may be transmitted to the specific terminal 100_1.

However, the terminal to which the specific NFC card 10 is tagged may be changed.

Referring back to FIG. 20, the content providing server 300 may receive user identification information and identification information of the second tagged terminal from the NFC card 10 and the second tagged terminal (S710).

This assumes that a user using the first tagged terminal 100_1 and the second tagged terminal 100_2 are the same. That is, it can be applied when the person using the NFC card changes the mobile phone. Therefore, when the user changes the mobile phone and tags the NFC card 10 to the changed mobile phone, it is desirable to be able to control the provision of content to the mobile phone and the changed mobile phone that were used previously.

The content providing server 300 may control the provision of the predetermined content to the second tagged terminal 100_2 according to whether the received identification information matches the corresponding identification information stored in the database 400. It may be (S720).

For example, when the user changes the device tagging the NFC card, the content providing server 300 from the second tagged terminal (100_2) user identification information (A1), the identification information of the tagged device (B2) , NFC card identification information (C1) can be received.

Accordingly, the content providing server 300 may compare the identification information previously stored in the database 400. That is, A1, B1, C1 received and registered from the first tagged terminal 100_1 and A1, B2, C1 received from the second tagged terminal 100_2 may be compared.

Here, the content providing server 300 recognizes that A1 and C1 are the same but B1 is changed to B2. Accordingly, the content providing server 300 provides at least one of the first tagged terminal 100_1 and the second tagged terminal 100_2 with a guide message indicating that the provision of the content to the first tagged terminal 100_1 may be restricted. Can be provided in one.

22 is a flowchart illustrating another embodiment of an operation for providing a predetermined content by a content providing server when an electronic device to tag an NFC card is changed. FIG. 23 is a diagram for describing the exemplary embodiment shown in FIG. 22.

22 to 23, the content providing server 300 may determine whether identification information of the first tagged terminal 100_1 and identification information of the second tagged terminal 100_2 coincide with each other ( S800).

When the identification information of the first tagged terminal 100_1 does not match the identification information of the second tagged terminal 100_2, the content providing server 300 may form a first communication link formed with the first tagged terminal 100_1. In operation S820, the second tagged communication terminal may be newly connected (S820).

In addition, the content providing server 300 may transmit predetermined content to the second tagged terminal 100_2 through the second communication link. As described above, the content providing server 300 may provide the content in a streaming or download manner. In addition, the provided content is content associated with a tagged NFC tag, and the content is content provided based on a network address received from the second tagged terminal 100_2.

24 is an exemplary flowchart of an operation of storing a user's usage record in tagging of an NFC card at a content providing server.

Referring to FIG. 24, when the NFC tag 10 is tagged with at least one device at least one time (S431), the content providing server 300 may use user ID information whenever a tagging operation is performed. In operation S832, it may be monitored whether identification information (Device ID) of the tagged device and identification information (Card ID) of the NFC card match the identification information previously registered in the database 400.

As a result of the monitoring, the content providing server 300 may determine whether there is at least one identification information that does not match (S833). The content providing server 300 may change the content providing method when there is a mismatched identification information according to the monitoring result. That is, the content providing server 300 may limit the device to be downloaded or limit the device to be streamed (S834).

For example, the identification information may include identification information of a terminal on which the NFC card 10 is tagged and identification information of a user. Therefore, the other identification information is the same as the previously registered identification information, if only the identification information of the terminal tag the NFC card 10 is different, the content providing server 300 provides an unlimited amount of streaming content provision In this case, it is possible to limit the provision of the downloadable content. Also, for example, the content providing server 300 may limit both the streaming content providing and the download content providing.

On the other hand, the content providing server 300 may record and store the user's usage statistics for the tagging information for the particular NFC card 10. For example, it may record that the first NFC card has been tagged N times to the first terminal, and may record that the device tagged with the first NFC is changed from the first terminal to the second terminal.

Meanwhile, the content providing server 300 may transmit the user's tagging record for the specific NFC card to the user's terminal at predetermined intervals.

Hereinafter, an example of changing the manner in which the content providing server 300 provides predetermined content by reflecting the tagging record of the NFC card will be described. For example, when the NFC card purchased by the first user is transferred to the second user, the content providing server 300 may control the provision of the content corresponding to the NFC card.

FIG. 25 is an exemplary flowchart of an operation of providing content corresponding to the NFC card in a content providing server when both the user of the NFC card and a terminal tagged with the NFC card are changed with respect to the same NFC card.

26 to 27 are diagrams for describing the exemplary embodiment shown in FIG. 25.

25 to 27, the content providing server 300 may determine whether identification information of the first tagged terminal and identification information of the second tagged terminal are the same (S900). That is, the content providing server 300 may determine whether the terminal tagged with the same NFC card is changed.

Meanwhile, as a result of the determination, when identification information of the first tagged terminal and the second tagged terminal do not match, the terminal to which the NFC card is tagged is recognized as changed.

Thereafter, the content providing server 300 may determine whether the user ID information (User ID) registered in the first tagged terminal and the user ID information (User ID) registered in the second tagged terminal are the same (S910). ). That is, the content providing server 300 may determine whether the owner of the NFC card has changed.

If the identification information of the user registered in the first tagged terminal and the identification information of the user registered in the second tagged terminal do not match (S910: No), the content providing server 300 according to the content transmission method is the second The method of providing content to the tagged terminal may be controlled (S920).

As described above, the content transmission scheme may include a streaming scheme or a download scheme. In addition, the content transmission scheme may be set at the request of the user. For example, the user may be provided with the selected content by selecting either "listening" or "downloading" a particular music file.

For example, when providing content in a streaming manner, the content providing server 300 may transmit the content corresponding to the NFC card to the second tagged terminal in a streaming manner without restriction.

In addition, for example, when the content providing server 300 provides content in a download manner, the content providing server 300 may check the number of downloads of the corresponding content.

When the number of downloads exceeds a predetermined number of times (S940: YES), the content providing server 300 may stop the content transmission to the second tagged terminal (100_2) (S950). Alternatively, the content providing server 300 may transmit a message indicating that the predetermined number of downloads has been exceeded to the second tagged terminal 100_2.

In addition, when the number of downloads does not exceed a predetermined number of times (S940: No), the content providing server 300 may provide the second tagged terminal 100_2 with the content corresponding to the tagged NFC card to the download method. There is (S955).

Referring to FIG. 26, User A may transfer the purchased NFC card 10 to User B.

The user A may be in a state in which the NFC tag 10 is tagged with the first tagging terminal 100_1 and the identification information associated with the NFC card 10 is registered in advance in the content providing server 300.

In this case, when the user B who has received the NFC card 10 tags the NFC card 10 to the second tagging terminal 100_2 that he or she is using, the content providing server 300 is the second tagging terminal. Providing the content at 100_2, the streaming content providing is unlimited, and the downloading method providing the content can be controlled according to the number of downloads.

For example, the content providing server 300 when the user A has used all of the preset download number when purchasing the NFC card (which can be checked by referring to the NFC card usage record), the content downloading service to the second tagging terminal 100_2. Can be limited.

Referring to FIG. 27, as the NFC card 10 is tagged to the second tagging terminal 100_2, the content providing server 300 may display a standby screen for providing content corresponding to the NFC card. 100_2).

When the content providing server 300 receives a signal for requesting download of a predetermined content (AAAAAAA) through the idle screen, the content providing server 300 checks the usage record of the NFC card 10 and checks the corresponding content (AAAAAA). It may be determined whether the number of downloads exceeds the preset number of downloads.

As a result of the check, when the number of downloads of the corresponding content exceeds a preset number of downloads, the content providing server 300 may transmit a message indicating that the number of downloads has been exceeded to the second tagged terminal 100_2.

Meanwhile, the user may tag the purchased NFC card on his terminal to store the content downloaded from the content providing server in a memory and continuously use the stored content.

However, when the user loses his terminal, the content providing server 300 needs to restrict the execution of the content stored in the memory.

Hereinafter, an embodiment of controlling the execution of content previously stored in the terminal when the user loses the terminal will be described with reference to FIGS. 28 and 29.

28 is an exemplary flowchart of a content providing server operation for controlling execution of downloaded content according to NFC card tagging. FIG. 29 is a diagram for describing the exemplary embodiment illustrated in FIG. 28.

Referring to FIG. 28, when an NFC card is tagged to a predetermined terminal, the terminal tagged with the NFC card may include user ID information, device ID information on which the NFC card is tagged, and identification information of the NFC card. (NFC ID) may be registered through the content providing server 300 (S1010).

If the NFC card is tagged again after the NFC card registration process is terminated (S1020), the predetermined content may be received from the content server 300 (S1030). In addition, the terminal tagged with the NFC card may separately store the received content in a storage space (S1040).

When the content providing server 300 provides a predetermined content to the terminal tagged with the NFC card 10 in a download manner, the content providing server 300 monitors the tagging cycle of the NFC card 10 to the terminal. It may be (S1040).

That is, when a user loses the first terminal while a predetermined content is provided to the first terminal in a download manner, the user who has acquired the first terminal may use the content stored in the first terminal without permission. . In order to prevent this, the content providing server 300 may control the NFC card 10 to be tagged with the first terminal according to a predetermined cycle so that the stored content is executed.

That is, when the predetermined content is provided to the first terminal in a download manner, if the content providing server 300 does not have a tagging operation of the NFC card for a predetermined period (S1050), execution of the content stored in the first terminal is performed. It may be limited (S1060).

Accordingly, the person who has acquired the first terminal cannot play the content stored in the first terminal without the NFC card.

Referring to FIG. 29, the first terminal 100 is tagged with an NFC card through an NFC communication module, and receives content corresponding to the NFC card from a content providing server 300 and stores it in a memory.

The content stored in the memory may include both content obtained by NFC card tagging and content not related to tagging of the NFC card. In order to distinguish this, the content providing server 300 may add predetermined identification marks I1 and I2 to the content provided by the first terminal 100 in a download manner according to the tagging of the NFC card.

Accordingly, the first terminal 100 may separately provide the downloaded contents (AAA, DDD) according to the NFC card tagging to the user.

When the user loses the first terminal 100 and reports the loss to the content providing server 300, the content providing server 300 may determine the NFC tagged content (AAA, DDD) stored in the first terminal 100. A control signal for limiting execution may be transmitted to the first terminal 100.

The control signal may include, for example, a signal for setting a period DRM in the NFC tagged content (AAA, DDD).

Accordingly, when the person who acquired the first terminal 100 wants to execute the content AAA stored in the memory, the first terminal 100 indicates that the execution request for the execution restricted content has been input. You can inform. Then, the content providing server 300 may transmit a message for inducing tagging of the NFC card corresponding to the content stored in the first terminal 100 to the first terminal 100.

As described above, each of the content providing related methods performed in the content providing system 1 according to the present invention may be implemented in a program form that can be executed by various computer means and recorded in a computer readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination.
