6 is a diagram illustrating execution of an authentication application and issuance of a coupon according to an exemplary embodiment.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the embodiments. Also, like reference numerals in the drawings denote like elements.

After the user terminal executes the authentication application, the user terminal may receive sound waves from the electronic stamp. For example, the user terminal may receive sound waves through a speaker installed in the user terminal. The sound wave may be a sound file in the inaudible frequency band (for example, 18 kHz to 22 kHz).

The user terminal may extract identification information uniquely assigned from the sound wave received from the electronic stamp (110). For example, the identification information may be uniquely assigned to the electronic stamp. In order to distinguish the electronic stamp from other electronic stamps, identification information may be given to the electronic stamp.

The user terminal may demodulate the sound wave and extract the identification information included in the sound wave. The sound wave may be a sound file modulated by an electronic stamp. For example, the electronic stamp may modulate sound waves using analog modulation techniques such as amplitude modulation (AM) and frequency modulation (FM). In addition, the electronic stamp may modulate the sound wave using a pulse modulation technique as well as a digital modulation technique such as quadrature amplitude modulation (QAM). The user terminal may demodulate the received sound wave based on the modulation technique used by the electronic stamp.

The user terminal may check whether the extracted identification information is in the identification information list (120). The identification information list may be a list in which identification information provided to the electronic stamp is recorded. In the identification information list, a plurality of identification information may be recorded.

According to one side, the identification information list may be received from the server. For example, according to the execution of the authentication application, the user terminal may call the server. In response to the call, the server may send the identification information list to the user terminal.

According to another side, the user terminal may transmit a query for checking whether there is identification information in the identification information list stored in the server to the server. The user terminal may receive a response to the query to check whether the identification information is in the identification information list.

At least one touch event may occur when the electronic stamp contacts the touch interface (130). The electronic stamp may include a conductive tip, and the tip may be at least one. For example, the touch event may be caused by an electrical signal generated when the touch interface contacts at least one tip of the electronic stamp. In another example, the touch event may be caused by pressure applied to the touch interface via at least one tip of the electronic stamp. The generation of the above-described touch event is only an example matter according to an embodiment, and the generation of the touch event is not limited to the above-described matter.

The user terminal may receive at least one touch event generated by contact between the electronic stamp and the touch interface (130).

If the identification information is in the identification information list, the user terminal may generate an authentication result based on the touch event. That is, to generate an authentication result, the user terminal may use identification information and a touch event. The authentication result may include a result indicating that authentication is performed and a result indicating that authentication is not performed.

The user terminal may visually display the predetermined authentication item corresponding to the authentication result on the display (140). For example, in the case of a result indicating that authentication is performed, an authentication item indicating completion of authentication may be output. Alternatively, in the case of a result indicating that authentication is not performed, an authentication item indicating an authentication failure may be output. According to one side, the user terminal may provide at least one of audio feedback and tactile feedback to the user of the user terminal simultaneously with the visual display of the predetermined authentication item. For example, when an authentication item indicating completion of authentication is displayed, the user terminal may provide vibration to the user of the user terminal together with the sound effect.

The user terminal may determine whether the occurrence pattern of the touch event matches the predetermined pattern. The occurrence pattern of the touch event may include the number of touch events, the interval between the touch events, the location of the touch event, and the like. The occurrence pattern of the touch event may be determined by at least one of the number of tips of the electronic stamp and the position of the tip.

According to one side, when the identification information is in the identification information list, the user terminal may change the graphical attribute of the area in which the authentication item is to be displayed. For example, the user terminal may change the color of the boundary of the area where the authentication item is to be displayed or change the shade or color of the area.

According to one side, the user terminal may display an area in which the authentication item is displayed and an area in which the authentication item is to be displayed on the display. The area where the authentication item is displayed and the area where the authentication item is displayed may be visually distinguished. There may be a plurality of areas in which the authentication item is to be displayed, and when the identification information is in the identification information list, graphic attributes of all of the areas in which the authentication item is to be displayed may be changed.

Alternatively, when the identification information is in the identification information list, only graphic attributes of some areas of the area where the authentication item is to be displayed may be changed. More specifically, the user terminal may display the authentication items in the area in which the authentication items are to be displayed in order, and the user terminal may change only the graphic attributes of the areas in which the authentication items in the order are displayed. That is, the user terminal may change the graphic attribute of the area corresponding to the order in which the authentication items are displayed. By changing the graphic attribute of the area corresponding to the order in which the authentication items are displayed, the area corresponding to the order in which the authentication items are displayed may be distinguished from the area in which the authentication items are displayed and the area in which the authentication items are not displayed. In addition, the user terminal may change the graphic attribute of the area corresponding to the order in which the authentication items are to be displayed, thereby allowing the user of the electronic stamp to contact the area corresponding to the order in which the authentication items are to be displayed.

The authentication item may be displayed in an area corresponding to the order in which the authentication item is displayed, even if the electronic stamp does not contact the area corresponding to the order in which the authentication items are displayed.

According to one side, the user terminal may transmit the authentication result to the server so that the database in which the previous authentication result is recorded is updated.

According to one side, the user terminal may cancel the authentication result, if a cancellation sound wave is received from the electronic stamp. In this case, the user terminal may transmit the cancellation information of the authentication result to the server. The server may update the database in which the authentication result is recorded based on the cancellation information. When the authentication result is canceled, the user terminal may cause the authentication item corresponding to the canceled authentication result to disappear from the display.

According to one side, the user terminal may receive a plurality of sound waves with different carrier frequencies from the electronic stamp. Here, the same identification information may be included in a plurality of sound waves having different carrier frequencies. The user terminal may identify the carrier frequency and generate an authentication result corresponding to the identified carrier frequency.

For example, one of the plurality of sound waves having different carrier frequencies may be the aforementioned cancel sound file. The user terminal may identify the carrier frequency of the cancel sound wave, thereby canceling the authentication result. When the authentication result is canceled, an authentication item corresponding to the canceled authentication result may be deleted. That is, it may be determined whether the authentication item is deleted according to the carrier frequency.

As another example, when a user of a user terminal purchases coffee and dessert in a coffee shop, the user terminal may receive sound waves having a first carrier frequency and a second carrier frequency. The user terminal can identify each carrier frequency and generate an authentication result corresponding to each carrier frequency. After each authentication result is generated, the user terminal may display on the display a first authentication item corresponding to the first carrier frequency and a second authentication item corresponding to the second carrier frequency. Here, the first authentication item corresponds to the coffee purchased by the user, and the second authentication item corresponds to the dessert purchased by the user. That is, the type of authentication item to be displayed may be determined according to the carrier frequency.

As another example, when a user of a user terminal purchases three cups of coffee in a coffee shop, the user terminal may receive a sound wave having a third carrier frequency. The user terminal may identify the third carrier frequency and generate an authentication result corresponding to the third carrier frequency. The user terminal may display an authentication item corresponding to the authentication result on the display, and the user terminal may display three authentication items. That is, the number of authentication items to be displayed may be determined according to the carrier frequency.

As another example, the carrier frequency of the sound wave received by the user terminal may be different according to the gender of the user terminal.

The user terminal may be a portable device that a user can carry, such as a smartphone, a mobile phone, a tablet PC, and the like.

Referring to FIG. 2, the user terminal 200 includes a memory 210, a processor 220, and a touch interface 240.

The memory 210 may store an authentication application. The user terminal 200 may download the authentication application from the application market. Application Market is Apple

App store or google

It may include a play store.

The touch interface 240 may contact the electronic stamp 250 to generate at least one touch event. The electronic stamp 250 includes at least one conductive tip, and when the conductive tip contacts the touch interface 240, a touch event occurs.

The processor 220 may extract uniquely assigned identification information from the sound wave received from the electronic stamp according to the execution of the authentication application.

The processor 220 may check whether the identification information is in the identification information list. For example, the identification information list may be received from a server. When the authentication application is executed, the processor 220 may call the server through the communication unit 230. In response to the call, the server may transmit the identification information list to the user terminal 200 and the memory 210 may store the identification information list.

In another example, the processor 220 may generate a query for checking whether the identification information is in the identification information list stored in the server. The processor 220 may control the communicator 230 to transmit a query to the server. When a response to the query is received, the processor 220 may determine whether the identification information is in the identification information list using the response.

The processor 220 may receive at least one touch event occurring in the touch interface.

When the identification information is in the identification information list, the processor 220 may generate an authentication result based on the touch event. In addition, the processor 220 may visually display a predetermined authentication item corresponding to the authentication result on the display.

The processor 220 may determine whether the occurrence pattern of the touch event matches the predetermined pattern. For example, the processor 220 may determine whether the touch event occurrence pattern matches the predetermined pattern in consideration of the number of touch events, the interval between the touch events, the location of the touch event, and the like. If there is a match, the processor 220 may generate an authentication result indicating that authentication is performed. Or, if it does not match, the processor 230 may generate an authentication result indicating that the authentication is not.

When the identification information is in the identification information list, the processor 220 may change the graphic attribute of the area in which the authentication item is to be displayed. For example, the user terminal 200 may display the authentication items in the area where the authentication items are to be displayed in order. The user terminal 200 may change the graphic attribute of the area corresponding to the order in which the authentication items are to be displayed, so that the user of the electronic stamp may contact the area corresponding to the order in which the authentication items are to be displayed. The authentication item may be displayed in an area corresponding to the order in which the authentication item is displayed, even if the electronic stamp does not contact the area corresponding to the order in which the authentication items are displayed.

According to one side, the user terminal 200 may further include a communication unit 230 for transmitting the authentication result to the server so that the database in which the previous authentication result is recorded is updated.

According to one side, the processor 220 may cancel the authentication result, if a cancellation sound wave is received from the electronic stamp 250. In addition, the processor 220 may control the user terminal 200 such that the authentication item corresponding to the canceled authentication result disappears from the display.

Since the details described with reference to FIG. 1 may be applied to the user terminal 200 illustrated in FIG. 2, a detailed description thereof will be omitted.

3 is a diagram illustrating an operation of a user terminal and an electronic stamp, according to an exemplary embodiment.

Referring to FIG. 3, an authentication item is displayed in area 1 310 and area 211 of the display of the user terminal 300. The first area 310 and the second area 311 are areas in which the aforementioned authentication item is displayed. The above-described authentication items are displayed in areas 3 through 12. It is now time to display the authentication items in area 3. That is, area 3 corresponds to the order in which the aforementioned authentication items are displayed.

The user terminal 300 may receive a sound wave output from the electronic stamp 330.

Although not shown in FIG. 3, the user terminal 300 may change graphic attributes of an area where an authentication item is to be displayed in response to the reception of sound waves. Alternatively, when the identification information included in the sound wave is in the identification information list, the user terminal 300 may change the graphic attribute of the area where the authentication item is to be displayed. For example, the user terminal 300 may change graphic attributes of all the areas 3 to 12.

As another example, the user terminal 300 may change graphic attributes of an area (ie, area 3) corresponding to the order in which the authentication items are displayed. By changing the graphic properties of area 3, area 3 can be distinguished from areas 4 to 12.

The user terminal 300 may receive sound waves and wait for the occurrence of at least one touch event 320 to 322. For example, if there is no occurrence of a touch event within a predetermined time, the user terminal 300 may output a message for contacting the electronic stamp 330 to the touch interface. Alternatively, if the touch event does not occur within a predetermined time, the user terminal 300 may end the procedure for displaying the authentication item. When the procedure for displaying the authentication item is terminated, the user terminal 300 may output a message associated with the sound wave retransmission of the electronic stamp 330.

The touch events 320 to 322 may be generated by the contact of the electronic stamp 330. Referring to FIG. 3, the electronic stamp 330 contacts area 3 and touch events 320 to 322 occur. The user terminal may check whether the occurrence pattern of the touch events 320 to 322 matches the predetermined pattern. For example, the user terminal 300 may use another touch input means (for example, a part of the body or a conductive material) through a pattern of occurrence of a touch event, such as three touch events and a touch event located at a vertex of a triangle. It can be seen that the electronic stamp 330 is not in contact. The user terminal 300 may display the authentication item in area 3 only when the occurrence pattern of the touch events 320 to 322 matches the predetermined pattern.

According to one side, even if the electronic stamp 330 touches another area (for example, area 6) other than area 3, the user terminal 300 may display the authentication item in area 3. That is, when the occurrence patterns of the touch events 320 to 322 coincide with the predetermined patterns, the user terminal 300 may correspond to the area corresponding to the order in which the authentication items are displayed, regardless of the area where the electronic stamp 330 touches. That is, the authentication item may be displayed in area 3).

Referring to FIG. 4, the server may receive an authentication result according to an execution of an authentication application installed in a user terminal (410).

After executing the authentication application, the user terminal may receive a sound wave from the electronic stamp, and extract identification information uniquely assigned to the sound wave. Here, the identification information may be identification information uniquely assigned to the electronic stamp. The user terminal may check whether the identification information is in the identification information list. When the identification information is in the identification information list, the user terminal may generate an authentication result based on at least one touch event generated when the electronic stamp contacts the touch interface.

The server may update 420 a database in which previous authentication results have been recorded.

The server may transmit the identification information list to the user terminal in response to the execution of the authentication application.

The server may receive a query from the user terminal for checking whether the identification information is in the identification information list stored in the server. In addition, the server may transmit a response to the query to the user terminal. The response that the server sends to the user terminal may be either a response that the identification information is in the identification information list or a response that the identification information is not in the identification information list.

When the user terminal receives the cancel sound wave and the authentication result is canceled, the server may receive cancellation information of the authentication result from the user terminal. The server may update the database in which the authentication result is recorded by using the cancellation information.

When the user terminal receives a plurality of sound waves having different carrier frequencies, the server may receive a plurality of authentication results corresponding to each of the carrier frequencies. The server may update the database in which the previous authentication result is recorded based on the authentication result.

In the method of operating the server illustrated in FIG. 4, the details described with reference to FIGS. 1 to 3 may be applied as it is, and thus, detailed description thereof will be omitted.

The user terminal 520 executes the authentication application (521). Authentication applications can be provided in the application market.

In response to the execution of the authentication application, the user terminal 520 may call the server 530, and the server may transmit a list of identification information to the user terminal 520 in response to the call (522). According to one side, the process of the user terminal 520 to request the server 530 to receive the identification information list can be omitted. Instead, the user terminal 520 may extract the identification information from the sound wave, and then transmit a query to the server 530 to confirm whether the identification information is in the identification information list stored in the server 530.

The user terminal 520 may receive a sound wave from the electronic stamp 510 (523). The electronic stamp 510 may modulate the sound wave so that uniquely assigned identification information is included in the sound wave. The user terminal 520 may extract identification information from the received sound wave (524). For example, the user terminal 520 may extract identification information by demodulating the sound wave received through the modulation technique used by the electronic stamp 510.

The user terminal 520 may check whether the extracted identification information is in the identification information list (525). If the identification information is in the identification information list, the user terminal 520 may change the graphic attribute of the area in which the authentication item is to be displayed. For example, the graphic attribute of the area corresponding to the order in which the authentication items are displayed may be changed.

The electronic stamp 510 may contact 526 the touch interface. When a contact is made, a touch event may occur (527), and the user terminal 520 may receive a touch event. The user terminal 520 may identify an occurrence pattern of the received touch event, and determine whether the occurrence pattern matches a predetermined pattern.

When the occurrence pattern of the touch event matches the predetermined pattern, an authentication result of the extracted identification information may be generated. The user terminal 520 may display an authentication item corresponding to the authentication result on the display (528). In addition, the user terminal 520 may transmit an authentication result to the server 530 (529). On the other hand, unlike shown in Figure 7, the authentication result may be transmitted to the server 530 before the display of the authentication item.

The server 530 may update the database in which the previous authentication result is recorded using the authentication result received from the user terminal 520 (531).

Referring to FIG. 6, a screen of an authentication application is displayed on the display 610 of the user terminal. The authentication item is displayed in the first area and the second area. Areas 3 to 10 are areas in which the authentication item is to be displayed. Area 3 of the areas in which the authentication items are to be displayed is an area corresponding to the order in which the authentication items are displayed.

In addition, the display 610 may display a coupon area together with an area where an authentication item is displayed and an area where the authentication item is to be displayed.

The display 620 displays a predetermined number of authentication items. When a predetermined number of authentication items are displayed, the coupon area 621 may be in an activated state. Since the number of authentication items is less than the predetermined number in the display 610, the coupon area is in an inactive state.

When a touch input is applied to an area displayed on the display, when there is a response according to the touch input, the area displayed on the display is in an active state. For example, when a touch input is applied to a specific area to output a pop-up window or a message, the specific area is in an active state. Even if a touch input is applied to an area displayed on the display, if there is no response to the touch input, the area displayed on the display is in an inactive state.

Since the coupon area 621 of the display 620 is in an activated state, when a touch input is applied to the coupon area 621, there is a response accordingly. For example, a beverage free gift coupon may be displayed on the display according to a touch input as displayed on the display 630.

According to one side, the user may need an electronic stamp in order to use the free drink coupons. The user terminal on which the free drink coupon is displayed may receive sound waves from the electronic stamp. Identification information included in the sound waves is extracted, and the electronic stamp contacts the touch interface. The user terminal may generate a coupon use authentication result, and transmit the coupon use authentication result to the server. In addition, the user terminal may display an authentication item corresponding to the coupon use authentication result on the display. Since the process of generating the result of using the coupon authentication shown in FIG. 6 may be applied in the same manner as the process of generating the authentication result described with reference to FIGS. 1 to 5, detailed description thereof will be omitted.
