The first transaction request signal may be generated based on an operation of the first terminal device 120, an input of a first user, and/or an interaction between the first terminal device 120 and the second terminal device 130.

A method of generating the first transaction request signal will be described in more detail below with reference to FIGS. 6 and 7.

In step 426, the communication unit 210 may receive a plurality of transaction request signals from the electronic transaction server 110 from a plurality of terminal devices. The plurality of terminal devices may be terminal devices including a first terminal device 120 and a second terminal device 130. Each user of the plurality of terminal devices may be a user who wants to perform an electronic transaction. In other words, each of the plurality of transaction request signals received by the electronic transaction server 110 may be a signal transmitted from a terminal device of a user who wishes to perform an electronic transaction.

For example, the first transaction request signal is a transaction request signal transmitted from the first terminal device 120 among the plurality of transaction request signals, and the second transaction request signal is the second terminal device 130 among the plurality of transaction request signals. It may be a transaction request signal transmitted from

In other words, the first transaction request signal may be a signal for requesting an electronic transaction from the electronic transaction server 110 by a first user with a second user or a user who satisfies a predetermined condition among a plurality of users, and 2 The transaction request signal may be a signal for requesting an electronic transaction from the electronic transaction server 110 by a second user with a first user or a user who satisfies a predetermined condition among a plurality of users.

In step 428, the control unit 220 is based on the plurality of transaction request signals received by the communication unit 210, the first terminal device 120 and the second terminal device 130 for an electronic transaction among the plurality of terminal devices. ) Can be selected.

The control unit 220 includes a first terminal device 120 and a second terminal device in which an electronic transaction is to be made, based on the terminal device that has transmitted the transaction request signal included in each of the transaction request signals and information on the user of the terminal device. (130) can be selected.

Each transaction request signal of the transaction request signals received by the communication unit 210 generates location information related to the location of the terminal device where the corresponding transaction request signal is generated, account information on the user's account of the terminal device, and a corresponding transaction request signal. It may include one or more pieces of visual information about the time.

The first transaction request signal is among the location information related to the location of the first terminal device 120, account information on the user's account of the first terminal device 120, and time information on the time at which the first transaction request signal is generated. It may contain more than one piece of information.

For example, the first transaction request signal includes account information of a first user and/or information on the first terminal device 120, which is information about a party to an electronic transaction, and account information of a second user as a counterpart of the electronic transaction, and/or Alternatively, information on the second terminal device 130 may be included.

The first transaction request signal and the second transaction request signal may be equivalent signals or signals corresponding to each other. For example, the first transaction request signal and the second transaction request signal may differ from each other only in information on a subject of a transaction, information on a counterparty, and information on a terminal device.

In step 428, the control unit 220 provides information on one or more of the location information of the terminal device of each transaction request signal of the plurality of transaction request signals, the user's account information, and the time information regarding the time when the corresponding transaction request signal is generated. Based on the plurality of terminal devices, the first terminal device 120 and the second terminal device 130 in which an electronic transaction is to be performed may be selected.

The user's account information may include unique information about each user who is provided with a service through the electronic transaction server 110. In other words, the account information may be different for each user and may include information unique to each user. The user's account information may be information for the control unit 220 to distinguish or identify a first user and a second user in a virtual economic market in which an electronic transaction is made.

The location information of the terminal device may be information indicating a physical location of the terminal device. It may be information indicating the location of the terminal device itself or the location of a user using the terminal device obtained by the communication unit and/or sensor of the terminal device.

For example, the location information of the terminal device may include base station information on a base station to which the terminal device is connected, GPS information obtained by a GPS installed in the terminal device, and a wireless Internet access point (AP) to which the terminal device is connected. ) May include one or more of AP information.

The location information of the first terminal device 120 may be obtained by the sensor 340 and/or the communication unit 310.

The time information on the time when the transaction request signal is generated may include information on the time at which the transaction request signal is generated in the terminal device. Alternatively, the time information may be information of a time when the transaction request signal is transmitted to the electronic transaction server 110.

In step 428, the controller 220 is a first terminal device 120 in which an electronic transaction is to be performed among a plurality of terminal devices based on the similarity of the time information and the similarity of the location information between the plurality of transaction request signals. And a second terminal device 130 may be selected.

The similarity of the visual information may be a value that is inversely proportional to the difference between the times indicated by the transaction request signals. For example, as the times indicated by the visual information of the two transaction request signals are closer in time, the two transaction request signals may be more similar to each other in visual information.

The similarity of the location information may be a value that is inversely proportional to the distance between the locations indicated by the two transaction request signals. For example, as distances indicated by the location information of the two transaction request signals are spatially closer, the two transaction request signals may be more similar to each other in the location information.

For example, among the transaction request signals received by the communication unit 210, the control unit 220 selects the two terminal devices having the highest similarity of the time information of the transaction request signal and the position information of the terminal device, among the transaction request signals received by the communication unit 210. And the second terminal device 130.

In other words, the control unit 220 selects the first terminal device 120 and the two terminal devices present at the closest positions among the terminals that generated the transaction request signal simultaneously or within a predetermined first time among a plurality of terminal devices. 2 Can be selected as the terminal device 130.

For example, the control unit 220 may select two terminal devices having a similarity of the time information of the transaction request signal and/or the similarity of the location information of the terminal device less than or equal to a predetermined value to the first terminal device 120 and the second terminal device 130. Can be selected as

The control unit 220 adjusts the range of the first time period used to determine the similarity of the time information of the transaction request signal, so that the first terminal device 120 and the second terminal device ( 130) can increase the accuracy of the selection process.

When selecting as the first terminal device 120 and the second terminal device 130 by using the similarity of the time information and the similarity of the location information, the control unit 220 prioritizes the similarity of the time information and the similarity of the location information. Differences can be made and the order of use can be given. For example, if the reliability of the location information of the terminal device is lower than the reliability of the time information of the transaction request signal, the control unit 220 first determines the similarity of the time information of the transaction request signal and determines the similarity of the location information of the terminal device. By determining later, the accuracy of the process of selecting the first terminal device 120 and the second terminal device 130 in which an electronic transaction is to be made among a plurality of terminal devices may be improved. In other words, the control unit 220 first determines the similarity of the time information of the transaction request signal, thereby preferentially excluding other terminal devices having location information similar to those of the first terminal device 120 and the second terminal device 130 from electronic transactions. Yes, the first terminal device 120 and the second terminal device 130 can be selected.

The time information of the transaction request signal may include waiting time information.

The controller 220 may select the first terminal device 120 and the second terminal device 130 in which an electronic transaction is to be made in consideration of waiting time information when determining the similarity of the time information of the transaction request signal. The waiting time information may be information indicating a time for which the terminal device waits for more than a predetermined first time to establish an electronic transaction.

That is to say, in determining the similarity of the time information of the transaction request signal, when the difference between the times indicated by the time information is less than the sum of the predetermined first time and the second time indicated by the waiting time information , Time information of the transaction request signals may be determined to be similar to each other or may be regarded as the same. By determining the similarity of the time information of the transaction request signal by further considering the waiting time information, even when the first transaction request signal and the second transaction request signal are not generated within a predetermined first time, the first terminal device 120 and The second terminal device 130 may be selected as a terminal device in which an electronic transaction is to be made.

In step 430, the control unit 220 is based on the first transaction request signal and the second transaction request signal between the first user of the first terminal device 120 and the second user of the second terminal device 130 First information and second information related to the transaction may be generated.

In step 440, the communication unit 210 may transmit the first information to the first terminal device 120 and transmit the second information to the second terminal device 130.

That is to say, in step 442, the communication unit 310 of the first terminal device 120 receives the first user of the first terminal device 120 and the second terminal device 130 from the electronic transaction server 110. Information related to electronic transactions between users can be received. In addition, in step 444, the second terminal device 130 performs an electronic transaction between the first user of the first terminal device 120 and the second user of the second terminal device 130 from the electronic transaction server 110. You can receive related information.

The first information and the second information may include information related to an electronic transaction between the first user and the second user. For example, the first information and the second information may include information on the type of electronic transaction (eg, purchase, sale, or exchange of virtual goods) and virtual goods subject to the electronic transaction. Alternatively, the first information and the second information may include information for the first user and the second user to confirm or determine the initiation of an electronic transaction between the first user and the second user.

The first information and the second information may include the same information. For example, the first information and the second information may each include a predetermined confirmation message allowing the first user and the second user to approve the initiation of an electronic transaction.

A confirmation message for approval of an electronic transaction between the first user and the second user included in the first information and the second information will be described in more detail below with reference to FIG. 5.

In addition, the first information and the second information may include information corresponding to each other. For example, the content related to the party to the transaction included in the first information is the same as the content related to the counterparty to the transaction included in the second information, and the content related to the counterparty to the transaction included in the first information is included in the second information. It may be the same as the content related to the parties to the transaction.

The first information and the second information, which are information related to the electronic transaction between the first user and the second user, are the first user among the information used by the electronic transaction server 110 for electronic transactions between the first user and the second user, respectively. The personal information of and the personal information of the second user may be excluded. For example, the first information and the second information may not include account information of a first user and account information of a second user. In addition, the first information and the second information may not include information that can be used to identify the first user and the second user among information related to the first terminal device 120 and the second terminal device 130. have. That is to say, the first information and the second information include information at a level at which the first user and the second user can recognize the initiation of the electronic transaction between the first user and the second user, but one party of the electronic transaction It may not include information at a level that can identify the other party of the first user or the second user itself.

The first information and/or second information, which is information related to the electronic transaction between the first user and the second user, is on an identification mark that can be read by the first terminal device 120 and/or the second terminal device 130. May include information about.

The identification mark may be output to the display unit of the first terminal device 120 and/or the second terminal device 130, and by the reading unit of the first terminal device 120 and/or the second terminal device 130 Can be read. For example, the identification mark output on the display unit 330 of the first terminal device can be read by the reading unit of the second terminal device. Conversely, when the identification mark is output on the display unit of the second terminal device 130, the reading unit 350 of the first terminal device 120 can read the identification mark output on the second terminal device 130. .

In FIG. 4, an identification mark is output to the first terminal device 120 of the first terminal device 120 and the second terminal device 130, and the second terminal device 130 is sent to the first terminal device 120. The case of reading the printed identification mark is shown.

In step 450, the display unit 330 may output an identification mark. The identification mark may be output together with a message indicating that the electronic transaction can be initiated when the identification mark is read by the terminal device of the counterpart of the electronic transaction.

The identification mark output on the display unit 330 may be a QR code or a barcode.

In step 455, the reading unit of the second terminal device 130 may read the identification mark output on the display unit 330. For example, the second information received by the communication unit of the second terminal device 130 may include information required to execute a program capable of recognizing a QR code or a barcode in the second terminal device 130. As the second information is received, a program capable of recognizing a QR code or a barcode in the second terminal device 130 may operate a camera included in the reading unit of the second terminal device 130, and the display unit through the camera The QR code or barcode output on 330 can be read.

If the identification mark output on the display unit 330 is identified by the reading unit of the second terminal device 130, in step 460, the second terminal device 130 may generate a read signal. In other words, the read signal may be generated when the identification mark output to the first terminal device 120 is sensed by the reading unit of the second terminal device 130.

The read signal may be a signal requesting the electronic transaction server 110 to approve an electronic transaction between the first user and the second user. In other words, the identification mark may be a message inquiring whether the electronic transaction server 110 has initiated an electronic transaction transmitted to the first user and the second user, and the read signal generated by the second terminal device 130 is It may be a signal confirming the initiation of an electronic transaction between the first user and the second user.

In step 465, the communication unit 210 may receive a read signal for the identification mark from the second terminal device 130. In step 468, the read signal may be transmitted from the second terminal device 130 to the electronic transaction server 110.

In step 470, the controller 220 initiates an electronic transaction between the first user and the second user when the received read signal corresponds to the identification mark included in the first information transmitted to the first terminal device 120 It is possible to generate approval information indicating approval of

The approval information may be information indicating that initiation of an electronic transaction between the first user and the second user is approved. The authorization information may be generated when the read signal received by the electronic transaction server 110 corresponds to the identification mark output on the display unit of the first terminal device 120.

The identification mark output on the display unit 330 may not be readable by a terminal device other than the second terminal device 130. For example, in order to read the identification mark, information unique to the second terminal device 130 or information unique to the second terminal device 130 may be requested. The information for reading the identification mark includes a password stored by the second terminal device 130, a serial number of the second terminal device 130, an identifier of the second terminal device 130, an identifier of a second user, It may be a key of the second terminal device 130, a key of a second user, a public key of the second terminal device 130, a public key of a second user, and the like.

When a terminal device other than the second terminal device 130 attempts to read the identification mark output on the display unit 330, an error message is output to another terminal device that attempts to read without information required for reading the identification mark. Can be.

Alternatively, a terminal device other than the second terminal device 130 may identify a QR code or a barcode that is an identification mark output on the display unit 330, and transmit a read signal generated by identification to the electronic transaction server 110. Can be transmitted. In this case, the electronic transaction server 110 may determine that the read signal from the other terminal device has not been transmitted from the second terminal device 130, and error information including an error message to the other terminal device Can be transmitted.

In step 480, the communication unit 210 may transmit the authorization information generated by the control unit 220 to the first terminal device 120 and the second terminal device 130. That is, in steps 482 and 484, the first terminal device 120 and the second terminal device 130 indicate approval of the initiation of an electronic transaction between the first user and the second user from the electronic transaction server 110. You can receive approval information.

The approval information generated by the control unit 220 may include information that enables the first user and the second user to recognize that the initiation of electronic transactions between each other is approved. In other words, a message indicating that initiation of an electronic transaction between the first user and the second user is approved may be output on the display units of the first terminal device 120 and the second terminal device 130.

The authorization information generated by the control unit 220 includes information at a level that allows the first user and the second user to recognize that the electronic transaction between the first user and the second user has been initiated, but one party of the electronic transaction It may not include information at a level that can identify the other party, the first user or the second user itself. For example, the authorization information may be information excluding personal information of a first user and personal information of a second user among information used by the electronic transaction server 110 for an electronic transaction between a first user and a second user, respectively.

When the approval information is received by the first terminal device 120 and the second terminal device 130, in step 486, the control unit 320 of the first terminal device 120 may generate a first confirmation signal. . Also, in step 488, the control unit of the second terminal device 130 may generate a second confirmation signal.

In step 492, the communication unit 310 of the first terminal device 120 may transmit the generated first confirmation signal to the electronic transaction server 110. In addition, in step 494, the communication unit of the second terminal device 130 may transmit the generated second confirmation signal to the electronic transaction server 110. That is to say, in step 490, the communication unit 210 receives a first confirmation signal of an electronic transaction between the first user and the second user from the first terminal device 120, and receives the first confirmation signal from the second terminal device 130. A second confirmation signal of an electronic transaction between the user and the second user may be received.

The first confirmation signal and the second confirmation signal transmitted to the electronic transaction server 110 may include information on electronic transactions. For example, the first confirmation signal may include first product information related to the first virtual good that the first user will provide to the second user through an electronic transaction between the first user and the second user, and the second confirmation signal The second user may include second product information related to the second virtual product to be provided to the first user through an electronic transaction between the first user and the second user.

The first virtual goods and the second virtual goods may be virtual goods that are targeted for a specific transaction in an electronic transaction between the first user and the second user. The first virtual goods may be one of virtual goods included in the first user's account. The first virtual goods may be selected as a virtual goods subject to an electronic transaction when the first terminal device 120 is manipulated by the first user. The second virtual goods may be one of virtual goods included in the second user's account. The second virtual goods may be selected as a virtual goods subject to an electronic transaction when the second terminal device 130 is manipulated by the second user. For example, the first virtual goods and the second virtual goods may each be a game item used on the mobile game software.

The first goods information may include an identifier of the first virtual goods or a name of the first virtual goods for distinguishing the first virtual goods from other virtual goods. The second goods information may be an identifier of the second virtual goods or a name of the second virtual goods for distinguishing the second virtual goods from other virtual goods. Even if the identifiers for virtual goods of the same type, if the quantity of the virtual goods is different from each other, the above identifiers may be different from each other. In other words, the identifier of the virtual goods may be determined according to the type and quantity of the virtual goods.

In step 495, the control unit 220 between the first user and the second user based on the first confirmation signal and the second confirmation signal transmitted from the first terminal device 120 and the second terminal device 130, respectively. Electronic transactions can be applied.

In step 495, the first virtual goods of the first user and the second virtual goods of the second user may be exchanged with each other, and the first user and the second terminal device 130 2 The completion of an electronic transaction between users may be notified.

In step 440, the first information transmitted to the first terminal device 120, which is information related to the electronic transaction between the first user and the second user, and the second information to the second terminal device 130 are the first user And it may include a confirmation message for approval of the electronic transaction between the second user. The confirmation message included in the first information and the confirmation message included in the second information may be the same information. Alternatively, the confirmation message included in the first information and the confirmation message included in the second information may differ only in the information on the party and the other party of the electronic transaction, and the rest may be the same message. The confirmation message included in the first information and the second information may be information indicating a confirmation message.

In step 510, the display unit 330 of the first terminal device 120 may output a confirmation message for an electronic transaction between the first user and the second user based on the received first information. In step 520, the display unit of the second terminal device 130 may output a confirmation message for an electronic transaction between the first user and the second user based on the received second information. For example, the confirmation message may be a confirmation window that pops up on the display of the terminal device.

The user of the terminal device on which the confirmation message is displayed may respond to the electronic transaction server 110 to confirm or cancel the start of an electronic transaction with respect to the confirmation message received by the terminal device. For example, the confirmation message may include a confirmation and/or cancel button for approval of the electronic transaction initiation. When the confirmation button of the confirmation message is pressed, an electronic transaction may be initiated. Alternatively, when the cancel button of the confirmation message is pressed, the electronic transaction may be withdrawn.

In step 532, the communication unit 310 of the first terminal device 120 may transmit a first response signal generated by the control unit 320 to the electronic transaction server 110. Likewise, in steps 525 and 534, the second terminal device 130 may generate a second response signal and transmit a second response signal to the electronic transaction server 110.

In step 530, the communication unit 210 may receive a first response signal for the confirmation message from the first terminal device 120, and a second response signal for the confirmation message from the second terminal device 130 Can receive.

The first response signal and the second response signal received by the communication unit 210 may be signals generated when, for example, a confirmation or cancel button of a confirmation message is pressed by a first user and a second user.

In step 540, the control unit 220 determines whether the first response signal and the second response signal received by the communication unit 210 determine an electronic transaction between the first user and the second user. It is possible to determine whether the content is to withdraw the electronic transaction between the two.

When both the first response signal and the second response signal received by the communication unit 210 are signals indicating confirmation of the start of an electronic transaction between the first user and the second user, in step 470, the control unit 220 It is possible to generate approval information indicating approval of the initiation of an electronic transaction between the first user and the second user. The approval information generated by the control unit 220 may be information indicating that the initiation of an electronic transaction between the first user and the second user is approved.

The approval information generated by the control unit 220 is a second response of the electronic transaction server 110 to the first response signal and the confirmation message of the first terminal device 120 to the confirmation message. It can be generated upon receiving the signal.

For the approval information generated by the control unit 220, contents related to the approval information generated in step 470 described above with reference to FIG. 4 may be applied as it is.

If any one of the first response signal and the second response signal received by the communication unit 210 is not a signal indicating confirmation of the start of an electronic transaction between the first user and the second user, the control unit 220 receives approval information May not be created. Although not shown, when at least one of the first response signal and the second response signal is a signal indicating withdrawal of an electronic transaction between the first user and the second user, the control unit 220 determines that the electronic transaction is performed by the first user or It is possible to generate revocation information indicating that the revocation has been made by the second user. The communication unit 210 may transmit the withdrawal information generated by the control unit 220 to the first terminal device 120 and the second terminal device 130. The first user and the second user may recognize that the electronic transaction between the first user and the second user has been withdrawn through the withdrawal information received by the first terminal device 120 and the second terminal device 130.

Since the technical contents described above with reference to FIGS. 1 to 4 may be applied as they are, a more detailed description will be omitted below.

That is to say, the first transaction request signal and the second transaction request signal received by the communication unit 210 of the electronic transaction server 110 are generated as an interaction between the first terminal device 120 and the second terminal device 130. It may be a transaction request signal generated from the first terminal device 120 and the second terminal device 130, respectively.

The interaction between the first terminal device 120 and the second terminal device 130 may be a predefined operation of the first terminal device 120 and the second terminal device 130. As the first user and the second user operate their respective terminal devices according to a predefined operation method, the first terminal device 120 and the second terminal device 130 receive a first transaction request signal and a second transaction request signal. Each can be created.

The interaction may be an operation of a terminal device set in advance within a program used for electronic transaction. Alternatively, the first user and the second user may directly determine an operation method of the terminal device for generating a transaction request signal in a program used for electronic transaction. For example, the first user and the second user may set inputting a specific gesture on the touch screen of the terminal device as an interaction between the first terminal device 120 and the second terminal device 130 for generating a transaction request signal. have.

In order to increase the accuracy of generation of the transaction request signal, the control unit 320 includes a first time and a second time, which are operating times of the first terminal device 120 and the second terminal device 130 for generating the transaction request signal. A predetermined minimum distance between the first terminal device 120 and the second terminal device 130 for generating a transaction request signal may be adjusted.

When the first terminal device 120 and the second terminal device 130 come into contact or the first terminal device 120 and the second terminal device 130 are shaken within a predetermined distance, the first terminal device 120 Among the sensors 340, one or more of a gyroscope, an acceleration sensor, a shock sensor, and a balance sensor may detect the operation of the first terminal device 120. The controller 320 may generate a first transaction request signal based on an operation of the sensor 340 that detects the operation of the first terminal device 120. The operation time information of the sensor 340 that detects the operation of the first terminal device 120 may be included in the time information included in the first transaction request signal described above with reference to FIG. 4.
