[0177] FIGS. 9A, 9B, and 9C are drawings for explaining an operation of checking the distance and direction between a plurality of electronic devices according to one embodiment.

[0178] As shown in the above FIG. 9A, when the first electronic device (301) (e.g., the first electronic device (301) of FIG. 2 and / or the electronic device (301) of FIG. 3) and the second electronic device (401) are arranged back-to-back, and when each of the first electronic device (301) and the second electronic device (401) accesses the watch (901) among the wearable electronic devices, the relative distance (d1) and the relative angle (direction) between the first electronic device (301) and the second electronic device (401) can be measured using triangulation.

[0179] As shown in the above FIG. 9b, when the first electronic device (301) (e.g., the first electronic device (301) of FIG. 2 and / or the electronic device (301) of FIG. 3) and the second electronic device (401) are arranged back-to-back, and when each of the first electronic device (301) and the second electronic device (401) accesses an HMD (head mounted display) (903) among wearable electronic devices, the relative distance (d2) and the relative angle (direction) between the first electronic device (301) and the second electronic device (401) can be measured using triangulation.

[0180] As shown in the above FIG. 9c, when the first electronic device (301) (e.g., the first electronic device (301) of FIG. 2 and / or the electronic device (301) of FIG. 3) and the second electronic device (401) are arranged back-to-back, and when each of the first electronic device (301) and the second electronic device (401) accesses the GNSS subsystem (905), the relative distance (d1) and the relative angle (direction) between the first electronic device (301) and the second electronic device (401) can be measured using triangulation.

[0181] FIG. 10 is a diagram illustrating an operation of generating security information in a plurality of electronic devices according to one embodiment.

[0182] Referring to FIG. 10, when a shared selfie shooting mode attempt is confirmed between a first electronic device (301) (e.g., the first electronic device (301) of FIG. 2 and / or the electronic device (301) of FIG. 3) and a second electronic device (401), the first electronic device (301) and the second electronic device (401) can confirm security information to be used for establishing a secure connection.

[0183] If the pairing key and security information do not exist in the first electronic device, the first electronic device (301) may generate a temporary key (k1) by applying a grip detection value including, for example, a grip detection position and a grip pressure among the parameters of the first electronic device to a fussy matching algorithm (operation 1011).

[0184] If the pairing key and security information do not exist in the second electronic device, the second electronic device (401) may reverse transform the grip detection value including, for example, the grip detection position and the grip pressure among the parameters of the second electronic device (operation 1031), and apply the reversed grip detection value to a fussy matching algorithm to generate a temporary key (k2) (operation 1033).

[0185] Since the grip detection value of the first electronic device (301) and the grip detection value of the second electronic device (401) are opposite to each other, a temporary key (k1) generated by applying the grip detection value of the first electronic device (301) to a fussy matching algorithm and a temporary key (k2) generated by inversely transforming the grip detection value of the second electronic device (201) and applying the inversely transformed grip detection key to a fussy matching algorithm are the same key, and thus a secure connection can be established between the first electronic device (301) and the second electronic device (401) using the temporary key (K1) of the first electronic device (301) and the temporary key (K2) of the second electronic device (401) (Operation 1051).

[0186] FIG. 11 is a diagram for explaining an operation for exchanging data in a locked state of an electronic device according to one embodiment.

However, when the Wi-FiLock application included in the electronic device acquires WifiLock, the Wi-Fi radios can remain on until the electronic device is unlocked. Accordingly, when the electronic device (e.g., the main electronic device or the sub-electronic device) detects an attempt to take a selfie while in the locked state, the electronic device can receive second configuration information of the external electronic device from the external electronic device and exchange data with the external electronic device in a shared selfie shooting mode.

[0190] Referring to FIG. 12 above, in a locked state, an electronic device (e.g., the electronic device of FIG. 3) can establish a communication connection with an external electronic device using an NFC communication circuit to exchange data with the external electronic device.

[0191] When the setting mode of the above electronic device is entered into the setting mode of NFC, the NFC usage permission (1211) is activated, and the permission to use NFC only in the unlocked state (1213) is deactivated, the electronic device (e.g., main electronic device or sub electronic device) can receive second configuration information of the external electronic device from the external electronic device when it confirms an attempt to take a selfie in the locked state, and can exchange data with the external electronic device in the shared selfie taking mode.
