For example, the service server can receive a coupon generation command in which a user operation for activating the above-described operation object 631 is converted. The service server may generate coupon information in response to the coupon creation command.

7 is a flowchart illustrating a method for generating coupon information corresponding to digital content according to an embodiment.

For example, FIG. 7 is a flowchart illustrating a method of generating coupon information corresponding to digital contents in step 410 of FIG. 4 described above in more detail.

First, in step 711, the first user terminal 110 may transmit a user operation. For example, when the first user terminal 110 receives a user operation for an operating object set to generate coupon information from a user, the first user terminal 110 transmits a request signal corresponding to a user operation to the service server 140 in response to the input can do.

In step 712, the service server 140 may generate coupon information corresponding to the digital content in response to receiving the user operation. For example, the coupon information may be generated in various forms such as a serial number, a bar code, a QR code, and the generated coupon information may represent a unique value.

Then, in step 713, the first user terminal 110 may receive the generated coupon information from the service server 140. The first user terminal 110 may receive the coupon information and display it to the first user or store it in the internal memory.

In step 714, the first user terminal 110 may restrict access of the first user to the digital content. However, the present invention is not limited thereto, and the service server 140 may limit the access of the first user terminal 110 to the digital content. For example, after the coupon information is once created, access may be restricted to limit the use of the digital content by the first user. In addition, the first user terminal 110 or the service server 140 may provide access authority to the digital content of the first user terminal in response to at least one of generation of coupon information and attribution of digital content to the second user terminal Can be limited. The coupon information is generated for trading digital contents.

According to one embodiment, at least one of the first user terminal 110 and the service server 140 is configured to limit the use rights to the digital content of the user to which the digital content belongs in response to the generation of the coupon information corresponding to the digital content can do. For example, the user terminal 110 may change the value of a field indicating usage rights of the digital content of the user corresponding to the digital content.

Thereafter, the process from step 420 may be performed similarly to FIG.

8 is a flow chart illustrating a method for verifying coupon information in accordance with one embodiment.

For example, FIG. 8 is a flowchart showing the coupon information and the uploading method generated in FIG. 7 described above.

First, in step 810, the first user terminal 110 may upload the coupon information to the transaction server 130. Coupon information may be generated at step 410. According to one embodiment, the first user terminal 110 may upload the coupon information to the transaction server 130 automatically or manually. For example, in response to the generation of the coupon information, the first user terminal 110 may upload the coupon information to the transaction server 130 in association with the first transaction account without inputting a separate user operation. In another example, the first user terminal 110 may upload coupon information to the first transaction account in response to a user operation configured to register a transaction with the transaction server 130 of the first user. The uploaded coupon information may be stored in association with the first transaction account of the transaction server 130.

In step 820, the transaction server 130 can verify the uploaded coupon information. According to one embodiment, the transaction server 130 may verify the validity of the coupon information. For example, when the coupon information is a serial number, the transaction server 130 can verify the validity of the coupon information using part or all of the serial number. Specifically, when the serial number of the coupon information satisfies a predetermined condition, the transaction server 130 can determine that the coupon information is valid. Here, the predetermined condition may be a condition for determining whether the coupon information is valid or not, for example, a value derived by applying a predetermined algorithm to the coupon information is a predetermined value or the like. As described above, the transaction server 130 verifies the validity of the coupon information, thereby preventing the first user from uploading a false sale (for example, digital content corresponding to invalid coupon information) have.

In addition, the transaction server 130 can determine whether the digital content is belonged to the first user account, whether the digital content can be traded at the time of uploading, or the like based on the coupon information.

Further, the transaction server 130 can identify the content-specific information indicating the digital content based on at least a part of the coupon information. For example, if the coupon information is a serial number, the transaction server 130 may identify the content-specific information using a portion of the serial number (e.g., several leading digits). Here, the content-specific information is information indicating the corresponding digital content, and may include an ID of the digital content. The coupon information and the content-specific information will be described in detail in Fig.

Then, in step 830, the transaction server 130 may provide the information associated with the digital content to the second user terminal 120. According to one embodiment, the transaction server 130 may provide the information associated with the digital content to the second user terminal 120 in response to the verified coupon information being valid. For example, the information associated with the digital content may include the name, type, quantity, price, and content-specific information of the digital content.

According to one embodiment, when the coupon information is uploaded by the first user terminal, information on the digital content is provided to the second user based on the content-specific information, and the coupon-specific information may not be disclosed.

9 illustrates an exemplary coupon information according to an embodiment.

For example, coupon information 900 may include content-specific information 910 and coupon-specific information 920.

The content-specific information 910 is unique information indicating the digital content as described above, and can indicate the type of the digital content and the like. For example, it can be assumed that digital content is a game item, and "12345 " is assigned as content-specific information 910 to the game item.

The coupon-specific information 920 is information set differently for each of a plurality of digital contents, and can have a unique value for each generated coupon. For example, when an arbitrary user having the game item described above generates the coupon information 900 for the game item, "67890" is associated with the coupon information 900 generated by the user, 920). When another user generates coupon information 900 for the same game item, it can be assumed that "67899 " is included as coupon-specific information 920 for coupon information 900 generated by another user. As described above, even when the coupon information 900 is generated for the same kind of digital content, each coupon information 900 can include unique coupon-specific information 920. [

According to an embodiment, when the coupon information 900 is a serial number as described above, the number of the first n of the serial numbers (where n is an integer of 1 or more) may correspond to the content-specific information 910. According to one embodiment, the database of the service server or the transaction server can match and store the unique information and the digital contents. The first user terminal or the second user terminal may identify the digital content from the content-specific information 910 of the coupon information 900 from the above-described database. Accordingly, the second user terminal can identify the digital contents actually indicated by the uploaded coupon information 900, thereby preventing fraud in the transaction of digital contents.

8, the transaction server verifies the coupon information 900 in consideration of both the content-specific information 910 and the coupon-specific information 920 as the entire coupon information 900, for example, can do. Thus, even if an arbitrary user tries to upload coupon information 900 (for example, "12345-66666") arbitrarily created to the transaction server, the transaction server determines whether the coupon information 900 meets a predetermined condition It is possible to prevent the coupon information 900 from being uploaded in advance.

In addition, the transaction server provides the information associated with the identified digital content to the second user terminal based on the content-specific information 910 or the content-specific information 910, so that the second user terminal transmits the coupon information 900 can be confirmed. For example, if the second user terminal receives the content-specific information 910 (e.g., the number n of the first digit of the serial number), the second user terminal may use the content- The digital content corresponding to the content-specific information 910 can be identified in at least one of the transaction servers. At this time, the transaction server can exclude the provision of the coupon information 900 for the second user terminal. For example, the transaction server may not provide the coupon information 900 before the transaction, but may provide the coupon information 900 after the second user completes the transaction.

In addition, the content-specific information 910 can be generated to correspond to the personalized digital content. For example, Table 1 below may indicate content-specific information 910 corresponding to personalized digital content.

number Content-specific information Digital content Restricted use No. 1 content 1 2 3 4 5 Game item No limit No. 2 content 12345-01 Personalized game item No limit 3 times content 12345-01-09 Personalized game item Limited

Table 1 is for illustrating an example of the content-specific information 910 in the contents 1 to 3. For example, in Table 1, the content No. 1 is a simple game item, and "12345" can be assigned as the content-specific information 910. As the second content is a personalized game item, "01" in addition to "12345 " may be added as a separate identification number. The content No. 3 is set to use limitation for the personalized game item, and in addition to "12345-01 "," 09 "may be added as a separate identification number.

According to one embodiment, the personalization of the digital content may indicate that the digital content has been changed from the initial state by the user. For example, if the digital content is a game item, the personalization of the game item may correspond to enhancement of the game item, and a change in appearance of the game item in the game.

The "01" assigned to the personalization in Table 1 and the "09" assigned to the usage restriction are purely illustrative and not restrictive. The information indicating the personalization ("01" in Table 1) and the information indicating the use restriction ("09" in Table 1) are the back numbers of the basic content unique information 910 ("1234" in Table 1) The order of the content-specific information 910 and the additional information (e.g., personalization, use restriction, etc.) may be changed according to the design. The above-mentioned Table 1 is an example of the case where the coupon information 900 is composed of serial numbers. In the case where the coupon information 900 has a different data form such as a barcode and a QR code, Information can be added as a digital form.

According to one embodiment, the coupon information may further include information on a user to which the digital content corresponding to the coupon information belongs. For example, the information about the user may include information indicating the user's account or the like as an existing owner of the digital content.

FIG. 10 is a flowchart illustrating a coupon information transaction method according to an embodiment.

For example, FIG. 10 is a flowchart illustrating a method of performing a transaction in step 420 of FIG. 4 in more detail.

First, in step 1031, the second user terminal may send a purchase request to the first user terminal. For example, when a transaction server receives a purchase request from a second user terminal, the transaction server may forward the purchase request to the first user terminal.

And in step 1032 the first user terminal may send a purchase authorization to the transaction server. For example, the transaction server may receive a purchase authorization from a first user terminal. However, the present invention is not limited to this, and purchase approval at the first user terminal may be omitted. This is because uploading digital contents for trading on a transaction server in the first user terminal can be regarded as a desire to purchase.

Then, in step 1033, the transaction server may send a payment request to the second user terminal.

In step 1034, the second user terminal can perform settlement. For example, the second user terminal can settle an amount corresponding to the settlement request through a separate financial institution or the like. According to one embodiment, the second user terminal can deposit the corresponding amount in the virtual account of the financial institution. Here, the transaction server may receive the payment from the second user terminal.

Then, in step 1035, the transaction server can confirm the payment by the second user terminal. For example, the transaction server can verify the validity of the payment by the second user terminal. The validity of the payment may indicate whether or not the payment for the digital content has been normally paid. The transaction server can determine that the transaction for the digital content has been successfully completed when the payment is confirmed.

Each of the steps of FIG. 10 described above may represent an embodiment of a secure transaction as exemplary operations of a transaction. However, the present invention is not limited to this and other transaction methods may be applied.

11 and 12 are flowcharts illustrating a method of providing coupon information and digital content according to an exemplary embodiment.

11 is a flowchart illustrating a concrete method of providing digital contents corresponding to coupon information to a second user terminal in cooperation with a transaction server in step 430 of FIG.

First, in step 1131, the transaction server can provide coupon information to the service server. For example, the service server may receive coupon information from the transaction server.

Then, in step 1132, the service server, in response to receiving the coupon information, may assign the digital content corresponding to the coupon information from the first user terminal to the second user terminal. For example, the second user terminal can directly transfer the digital content from the first user account to the second user account without inputting additional coupon information.

In step 1133, the service server may restrict access to the digital content of the first user terminal. According to one embodiment, when coupon information corresponding to digital content is generated, the service server may add additional information (use restriction) to restrict use of the digital content to the coupon information. Accordingly, during a period in which the digital contents exist in the form of coupons, the use of the digital contents may be restricted.

FIG. 12 is a flowchart illustrating a concrete method of providing digital contents corresponding to coupon information to a second user terminal according to an input of coupon information at a second user terminal in step 532 of FIG. 5;

First, in step 1241, the second user terminal can receive the coupon information. For example, the second user terminal may receive the coupon information provided in step 531 from the second user. According to one embodiment, when the digital content is purchased, the second user terminal can acquire the coupon information through receiving a coupon number (e.g., serial number), receiving a gift, receiving a QR code, and the like.

In step 1242, the service server may receive the coupon information input from the second user terminal.

Then, in step 1243, the service server may provide digital content to the second user terminal. For example, in response to the input of the coupon information, the service server may provide the digital content corresponding to the coupon information to the second user terminal.

As described above, the coupon information received at the second user terminal is automatically or automatically input to the coupon information input interface in the service, so that the corresponding digital content can be attached to the second user account.

According to one embodiment, by trading digital content in the form of a coupon, fraudulent transactions on digital content can be reduced.
