In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposed between them. On the other hand, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.

When no second communication authentication number is requested from the first electronic device 1710 in operation 2413, the processor 1739 may end the process. The request for the second communication authentication number in operation 2413 may be a message that requests the input of a communication authentication number that is the same as a first communication authentication number displayed on the display unit 413 of the first electronic device 1710.

In operation 2415, the processor 1739 may input the second communication authentication number by the user. In operation 2417, the processor 1739 may transmit the input second communication authentication number to the first electronic device 1710. In operation 2419, the processor 1739 may receive second biometric information from the first electronic device 1710. In operation 2421, the processor 1739 may store the received second biometric information.

FIG. 25 is a flowchart illustrating an example method of unlocking the second electronic device according to an example embodiment of the present disclosure.

Referring to FIG. 25 according to an example embodiment, the second electronic device 1720 (for example, the processor 425) may identify that the second electronic device 1720 is in a locked state in operation 2511. According to one exemplary embodiment, the locked state of the second electronic device 1720 may refer to a state in which the second electronic device 1720 is supplied with power but authentication information, for example, a password, is not input so that a right to access the second electronic device 1720 and a right to implement a specific function are not allowed. Here, in the locked state, the second electronic device 1720 (for example, the processor 425) may display an input notification screen on the display 423 of the second electronic device 1720.

In operation 2513, the second electronic device 1720 and the third electronic device 1730 may perform a connection. For example, the second electronic device 1720 (for example, the processor 425) may perform a connection to the third electronic device 1730 using a short-range communication method. To this end, the second electronic device 1720 may store third identification information on the third electronic device 1730. The second electronic device 1720 (for example, the processor 425) may perform a connection to the third electronic device 1730 based on a user selection. The second electronic device 1720 (for example, the processor 425) may identify, using a communication method including Bluetooth Low Energy (BLE), that the third electronic device 1730 is located within a threshold radius. When the third electronic device 1730 is located within the threshold radius, the second electronic device 1720 (for example, the processor 425) may perform the connection to the third electronic device 1730.

In operation 2515, the second electronic device 1720 (for example, the processor 425) may transmit a request to receive second biometric information to the third electronic device 1730. When the request for the second biometric information is received from the second electronic device 1720 in operation 2515, the third electronic device 1730 (for example, the processor 1739) may transmit the second biometric information to the second electronic device 1720 in operation 2517.

In operation 2519, the second electronic device 1720 (for example, the processor 425) may perform authentication using the second biometric information received from the third electronic device 1730. When the second biometric information received from the third electronic device 1730 is the same as the second biometric information registered in operation 1821 of FIG. 18, the second electronic device 1720 (for example, the processor 425) may succeed in authentication using the second biometric information. When the authentication succeeds using the second biometric information, the second electronic device 1720 (for example, the processor 425) may release the locked state of the second electronic device 1720 in operation 2521. The second electronic device 1720 (for example, the processor 425) may release the locked state to provide the user with the right to access the second electronic device 1720 and the right to implement the specific function.

FIG. 26 is a flowchart illustrating an example method of operating the third electronic device according to an example embodiment of the present disclosure.

Referring to FIG. 26 according to an example embodiment, the processor 1739 may perform connection to the second electronic device 1720 in operation 2611. When second biometric information is requested from the second electronic device 1720 in operation 2613, the processor 1739 may perform operation 2615. When no second biometric information is requested from the second electronic device 1720 in operation 2613, the processor 1739 may end the process. In operation 2615, the processor 1739 may transmit the second biometric information stored in operation 1823 of FIG. 18 to the second electronic device 1720.

The operation of the second electronic device 1720 illustrated in FIG. 25 is the same as the operation of the second electronic device 420 illustrated in FIG. 14. Therefore, the flowchart in FIG. 14 may replace that for illustrating an operating method of the second electronic device 1720.
