Alternatively, when a threshold time elapses from the time the one-time link is created, the one-time link may expire and access through the one-time link may not be possible. According to the present embodiment, security can be improved by using a one-time link.

In operation 407 , the first processor 120 may transmit the one-time link and the first password to the second processor of the second electronic device 102 (eg, the second processor 120b of FIG. 2A ). In operation 409, the second electronic device 102 may attempt to access the one-time link transmitted after inputting the second password. In operation 411 , the first password checker (eg, the first password checker 127 of FIG. 3A ) compares the first password with the second password, and if they match, the access of the second electronic device 102 may be allowed. The password compared by the first password checker 127 may be the second password input to the second electronic device 102 and the first password generated by the link/password generator 126 .

After the second electronic device 102 is connected, the first processor 120 may transmit the first data of the first application 146a to the second processor 120b in operation 413 . A security technique may be applied to each operation of transmitting a signal between the first processor 120 and the second processor 120b. For example, Transport Layer Security (TLS) technology may be applied to some operations among a plurality of operations for transmitting a signal from the first processor 120 to the second processor 120b. As another example, the TLS technology may be applied to each of a plurality of operations for transmitting a signal from the first processor 120 to the second processor 120b.

According to the present embodiment, security technology is applied in each signal transmission process, so it may not be vulnerable to the threat of hacking. Also, since the target shared by the first electronic device 101 is an execution screen on which a specific application is executed, not the screen of the first electronic device 101 , the user's privacy can be protected.

4B is a diagram for explaining an application sharing method using the relay server 108 and electronic devices according to an embodiment. Parts common to the detailed description described in FIG. 4A will be omitted.

The first processor (eg, the first processor 120 of FIG. 2A ) may request the relay server 108 to create a one-time link in operation 415 . The link/password generator of the relay server 108 (eg, the link/password generator 115 of FIG. 3B ) may generate a one-time link and a first password in operation 416 .

In operation 417 , the relay server 108 may transmit the generated one-time link and the first password to the second processor (eg, the second processor 120b of FIG. 2B ). In operation 419 , the second electronic device 102 may attempt to access the relay server 108 through the link transmitted after inputting the second password.

In operation 421 , the second password checker of the relay server 108 (eg, the second password checker 113 of FIG. 3B ) compares the first password with the second password and if they match, the second electronic device 102 accesses can allow The password compared by the second password checker 113 may be the second password input to the second electronic device 102 and the first password generated by the link/password generator 115 . When the second password checker 113 permits the access, the relay server 108 may transmit an access permission message to the first electronic device 101 in operation 423 .

In operation 425 , the first processor 120 may transmit first data of a first application (eg, the first application 146a of FIG. 2B ). After the second electronic device 102 accesses the relay server 108 , the first data may be transmitted to the relay server 108 by the first processor 120 . The relay server 108 may transmit the received first data of the first application 146a to the second processor 120b in operation 427 .

A security technique may be applied to each operation of transmitting a signal between the first processor 120 , the relay server 108 , and the second processor 120b. For example, Transport Layer Security (TLS) technology may be applied to some operations among a plurality of operations for transmitting a signal from the first processor 120 to the second processor 120b. As another example, the TLS technology may be applied to each of a plurality of operations for transmitting a signal from the first processor 120 to the second processor 120b.

The relay server 108 may not include the process of storing the first data received from the first processor 120 in the relay server 108 . While the first data is transmitted to the second processor 120b via the relay server 108 , residual data related to the first data may not exist in the relay server 108 .

FIG. 5 illustrates a view other than the first application (eg, the first application 146a of FIG. 2A ) to be shared in the first electronic device (eg, the first electronic device 101 of FIG. 2A ) according to an embodiment. It is a diagram for explaining a phenomenon that occurs when a program is executed. According to an embodiment, in operation 510 , the first electronic device 101 may start sharing the first application 146a. In operation 520 , the first transmission determination module may specify the second application located in the uppermost activity of the first electronic device 101 . For example, the second application may be the same application as the first application 146a. As another example, the second application may be an application other than the first application 146a.

The first electronic device 101 may include a first transmission determination module and a second transmission determination module. In operation 530, the second transmission determination module may determine whether the first application 146a and the second application are the same. The second transmission determination module may return a result of comparing the first application 146a with the second application to the first processor (eg, the first processor 120 of FIG. 2A ).

For example, if the second application is the same as the first application 146a , in operation 540 , the second transmission determination module sends a first result value indicating that the first application 146a is being executed to the first processor 120 . can return As another example, if the second application is not the same as the first application 146a, in operation 560 , the second dispatch determination module may return a second result value indicating that another application is being executed to the first processor 120 . have.

The first processor 120 is transmitted to a second electronic device (eg, the second electronic device 102 of FIG. 2A ) or a relay server (eg, the relay server 108 of FIG. 2B ) in response to the return of the result value. It is possible to determine the data to be included in the signal. For example, in operation 550 , the first processor 120 may transmit the first data to the second electronic device 102 or the relay server 108 by including the first data in a signal in response to the return of the first result value. For another example, in operation 570 , the first processor 120 includes, in the signal, second data for stopping the transmission of the first data in response to the return of the second result value to the second electronic device 102 . Alternatively, it may be transmitted to the relay server 108 .

When transmitting the first data, the first processor 120 sends a notification indicating that the first application 146a is sharing to the display module of the first electronic device 101 (eg, the display module 160 of FIG. 1 ). can be displayed When the second processor (eg, the second processor 120b of FIG. 2A ) receives the second data from the first processor 120 or the relay server 108 , the user of the first electronic device 101 is performing another task may be displayed on the display of the second electronic device 102 . According to the present embodiment, when the user executes an application other than the first application 146a to be shared, the user's privacy is protected by not transmitting the audio data for the other application and the image data for the other application. can

6A is a diagram illustrating an example of a screen interface 610 related to application sharing according to an embodiment. The area on the display module (eg, the display module 160 of FIG. 1 ) corresponding to the first application to be shared on the screen interface 610 (eg, the first application 146a of FIG. 2A ) is maintained for a specified threshold time or longer. When touched, an app sharing icon 611 may be displayed on the top of the first application 146a.

When an area on the display module 160 corresponding to the app sharing icon 611 is touched, the first pop-up window 613 in the screen interface 610 may be displayed for a duration set by the user and then disappear. The first pop-up window 613 may selectively display phrases set to correspond to each situation. For example, when the app sharing icon 611 is touched, "A sharing link has been created." may be displayed. As another example, when a second electronic device (eg, the second electronic device 102 of FIG. 2A ) is connected through the sharing link, “the other party has participated.” may be displayed.

When the upper bar of the screen interface 610 is lowered, the notification bar 620 may be activated. When the first application 146a is sharing, a specified phrase may be displayed on the phrase display window 621 . For example, when the first application 146a is sharing, “screen sharing” may be displayed. As another example, when the first application 146a is sharing and the first password is set to QAVC, "screen sharing" and "sharing code: QAVC" may be displayed at the same time.

6B is a diagram illustrating another example of a screen interface 610 related to application sharing according to an embodiment. According to an embodiment, the screen interface 610 of the first electronic device (eg, the first electronic device 101 of FIG. 2A ) is the first application of the first application (eg, the first application 146a of FIG. 2A ). The sharing screen 630 may be displayed. A share icon 631 indicating that the screen is being shared may be displayed on the upper bar of the screen interface 610 . A media icon display window 633 may be displayed on the first sharing screen 630 . In the media icon display window 633 , a first icon 634 for determining whether to transmit audio data by the first application 146a and a second icon 634 for determining whether to transmit image data by the first application 146a ( 635) may be included.

In a situation in which the first processor (eg, the first processor 120 of FIG. 2A ) transmits voice data, the display module (eg, the display module 160 of FIG. 1 ) of the first electronic device 101 performs the first When a touch input (eg, a third touch input) for the icon 634 is received, voice data transmission may be stopped. When the display module 160 of the first electronic device 101 receives an additional touch input for the first icon 634 in a situation where the first processor 120 does not transmit the voice data, the voice data is transmitted can be

In a situation where the first processor 120 transmits image data, the display module 160 of the first electronic device 101 receives a touch input (eg, a fourth touch input) for the second icon 635 . In this case, image data transmission may be stopped. When the display module 160 of the first electronic device 101 receives a touch input for the second icon 635 in a situation where the first processor 120 does not transmit image data, the image data may be transmitted. can

As the user decides whether to transmit image data and audio data, the media icon display window 633 may be set to a total of four cases. Specifically, there may be cases in which both audio/video are transmitted (633a), only audio is transmitted (633b), only video is transmitted (633c), and neither audio/video is transmitted (633d).

The second pop-up window 641 is displayed in the second sharing screen 640 of the second electronic device (eg, the second electronic device 102 of FIG. 2A ), and the first electronic device 101 is displayed in the second pop-up window 641 . ), a phrase indicating that the user is using an application other than the first application 146a may be displayed. For example, the phrase “I am busy with other business” may be displayed.

According to an embodiment, in operation 710 , the display module (eg, the display module 160 of FIG. 1 ) may receive a first touch input lasting longer than a specified threshold time. The specified threshold time may include a time set by a user or a time set in the system. For example, if the user sets 1 second, the specified threshold time may be 1 second. As another example, if the user does not set it in advance, the designated threshold time may be 0.5 seconds, which is a time set in the system.

In operation 720 , the display module 160 may display an app sharing icon (eg, the app sharing icon 611 of FIG. 6A ) in response to the first touch input. In operation 730 , the display module 160 may receive the second touch input for the app sharing icon 611 and transmit the intent to the processor (eg, the first processor 120 of FIG. 2A ).

In operation 740 , the processor 120 may receive the intent and execute a first application (eg, the first application 146a of FIG. 2A ). In operation 750 , the processor 120 may generate a link for connecting the electronic device (eg, the first electronic device 101 of FIG. 1 ) to an external electronic device. The external electronic device may include at least one of a second electronic device (eg, the second electronic device 102 of FIG. 2A ) and a relay server (eg, the relay server 108 of FIG. 2B ). In operation 760, the processor 120 may transmit a signal including a link to the external electronic device.
