[0043] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0044] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0045] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0046] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device).

In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0047] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0048] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0049] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0050] An electronic device (101) according to one embodiment can provide a service related to biometric information by linking with a wearable electronic device (201) that senses biometric information.

[0051] FIG. 2 is a simplified block diagram of a wearable electronic device according to one embodiment.

[0052] Referring to FIG. 2, a wearable electronic device (201) according to one embodiment is an accessory device that can be worn on a user's body, and can be implemented to sense biometric information and transmit it to an electronic device (101) through a communication module (210).

[0053] According to one embodiment, a wearable electronic device (201) may include, but is not limited to, a communication module (210), a processor (220), a memory (230), a first biometric sensor (240), a second biometric sensor (250), and a sensor module (260). For example, in addition to the configuration illustrated in FIG. 2, the wearable electronic device (201) may further include other hardware configurations (e.g., audio input / output devices) illustrated in FIG. 1.

[0054] The communication module (210) of the wearable electronic device (201) may include a communication circuit. The communication module (210) may communicate with the communication module (190) of the electronic device (101) based on a wireless communication method. The wireless communication method may include, but is not limited to, ultra-wideband (UWB) communication that transmits and receives frequency signals in the GHz band and Bluetooth communication that transmits and receives radio frequency signals in a short distance according to the Bluetooth communication standard, and may be replaced with another communication method that can determine a connection or location between two electronic devices (e.g., the electronic device (101) and the wearable electronic device (201)). The ultra-wideband communication may not cause radio interference by other communication signals by distinguishing radio wave information per unit time using a wide bandwidth of the GHz band. For example, in ultra-wideband communication, the low band may be allocated from about 3.1 to about 4.8 GHz, and the high band may be allocated from about 7.2 to about 10.2 GHz. Bluetooth communication may include not only Bluetooth communication but also Bluetooth low energy (BLE) communication.

[0055] According to one embodiment, the first biometric sensor (240) may include an optical sensor (e.g., a biometric optical sensor, a photoplethysmography (PPG) sensor) implemented to measure biometric information of a user.

[0056] For example, the first biometric sensor (240) may include, but is not limited to, a light source that emits light, a light detector that receives light reflected from the user's body, and a sensor IC that measures reflected light received from the light detector. The first biometric sensor (240) may be used to measure and monitor biometric information of a user (or wearer) wearing the wearable electronic device (201). The first biometric sensor (240) may transmit the measured biometric information to the processor (220). The processor (220) can determine biological characteristics (e.g., saturation of percutaneous oxygen (SpO2), heart rate (HR), photoplethysmograph (PPG), galvanic skin response (GSR), bioelectrical impedance, blood sugar, hemoglobin concentration, triglyceride, body composition, alcohol index), stress, and / or blood pressure) based on the biological information transmitted from the first biological sensor (240).

[0057] The second biosensor (250) may include a biosensor that includes at least two electrodes (e.g., ECG electrodes) and can receive electrical changes in the biosensor by coming into contact with the biosensor through the electrodes.

[0058] For example, the second biosensor (250) may be an ECG (electrocardiogram) sensor that detects and amplifies a biopotential (e.g., a potential difference generated when a heart muscle contracts and relaxes) detected between electrodes to measure (or record) an electrocardiogram, but may also be replaced with another sensor that measures a biosignal by forming a closed loop state through at least two or more electrodes. The ECG sensor forms a closed loop state when different parts of the body (e.g., both hands) come into contact with the electrodes to generate a biologically meaningful ECG signal, and if a closed loop state is not formed between the ECG sensor and the body, the signals of the electrodes may be recognized as noise or unmeasurable as biologically meaningless values.

[0059] The second biometric sensor (250) can be used to identify and authenticate a user (or wearer) wearing the wearable electronic device (201). The second biometric sensor (250) can transmit signals measured from electrodes to the processor (220). The processor (220) can obtain an ECG signal (e.g., at the time when a closed loop state is formed) through at least two electrodes, measure (or confirm) a biometric characteristic (e.g., an ECG characteristic) from the ECG signal, and compare the measured biometric characteristic with a biometric characteristic (e.g., an ECG waveform rhythm, a pattern, a waveform peak, a slope characteristic information) pre-stored (or registered) in the wearable electronic device (201). When the measured biometric characteristic is higher than a certain standard (e.g., a matching rate of 90% or higher) by comparing the measured biometric characteristic with the stored biometric characteristic, the processor (220) can identify the wearer as a pre-registered user (e.g., a registered user) and complete user authentication. The processor (220) can identify a user as another user if the measured biometric characteristics are below a certain standard compared to the stored biometric characteristics.

[0060] The sensor module (260) may include various sensors that detect various information such as movement information, environmental information, and location information of the wearable electronic device (201). The sensor module (260) may include, but is not limited to, an acceleration sensor, a gyro sensor, a proximity sensor, an ambient light sensor or luminance sensor, an iris sensor, a temperature-humidity sensor, a touch sensor, an elevation sensor, a gesture sensor, a barometer sensor, a magnetic sensor, a grip sensor, an infrared (IR) sensor, and / or a time of flight (ToF) sensor, for example.

[0061] According to one embodiment, the first biosensor (240), the second biosensor (250), and the sensor module (260) may be implemented in an integrated form connected to one sensor IC.

[0063] Referring to FIGS. 3A to 3D , according to one embodiment, the wearable electronic device (201) illustrated in FIG. 2 may support a biometric information sensing function, a touch function, and a wireless communication function, and may refer to an electronic device that can be worn on a user's body. The wearable electronic device (201) may be, for example, a ring type (e.g., a smart ring) worn on a user's finger, but may also be implemented as another type of electronic device, such as a band type (e.g., a smart band) that does not include a display.

[0064] A wearable electronic device (201) according to one embodiment may include a first housing (3001) having an annular shape (e.g., an inner ring housing, a second ring housing, or a second housing portion) including an opening (3003) and a second housing (3002) coupled with the first housing (3001) (e.g., an outer ring housing, a first ring housing, or a first housing portion). The opening (3003) may be formed to a size such that a user's finger can be inserted therein. For example, the second housing (3002) may be formed of a material that is resistant to external impact or scratches, such as a metal material, ceramic, or stainless steel. A separate fixing or coating process may be performed on the second housing (3002) to implement color.

[0085] According to one embodiment, the processor (310) may set different allowable functions of the wearable electronic device (201) depending on the user recognition method identified as the registered user. For example, if the user recognition method is a first method including a mobile linkage recognition method, the processor (310) may allow functions that allow access to secure information, and if the user recognition method is a second method including a biometric characteristic recognition method based on an ECG signal, the processor (310) may set functions that allow access to secure information to be restricted.

[0086] A wearable electronic device (201) according to one embodiment (e.g., the electronic device (101) of FIG. 1) may include a housing having a ring shape.

[0089] According to one embodiment, the first sensor may include a photoplethysmography (PPG) sensor, and the second biosensor may include an electrocardiogram (ECG) sensor.

[0090] The instructions according to one embodiment may enable the wearable electronic device (201) to allow a second function related to the first biometric information when the user recognition method is the second method.

[0091] A wearable electronic device (201) according to one embodiment further includes a communication module, and the instructions may cause the wearable electronic device (201) to transmit the first biometric information monitored through the first sensor to an electronic device connected to the wearable electronic device through the communication module based on completion of user authentication.

[0092] The instructions according to one embodiment may restrict the wearable electronic device (201) to execute the first function if the identified user is a user authenticated by a user recognition method set for the first function based on a request for execution of the third function, and not to execute the first function if the identified user is not a user authenticated by the user recognition method set for the first function.

[0093] The instructions according to one embodiment may cause the wearable electronic device (201) to execute the first function when the identified user is a user authenticated by a user recognition method set for the first function and is connected to the electronic device, and to restrict the wearable electronic device (201) from executing the first function when the identified user is a user authenticated by a user recognition method set for the first function but is not connected to the electronic device.

[0098] FIG. 5 illustrates a user recognition operation method of a wearable electronic device according to one embodiment.

[0099] FIG. 5 shows an embodiment in which a processor (220, 310) of a wearable electronic device (201) can detect whether the wearable electronic device (201) is being worn in operation 510.

[0100] According to one embodiment, the processor (220, 310) can detect a device mounting / demounting state based on sensing information of sensors included in the electronic device. For example, as illustrated in FIG. 4, the processor (220, 310) can recognize a state in which one hand (410) approaches the wearable electronic device (201) and grabs a part of the second housing (3002) (e.g., the second electrode (355-2)) through a combination of sensors, and can detect a state in which the wearable electronic device (201) is mounted on a finger of the other hand (415) and a part of the first housing (3001) (e.g., the first electrode (355-1)) is in contact.

[0101] In operation 520, the processor (220, 310) can measure a biometric characteristic based on a closed-loop signal or an ECG signal of the first electrode (355-1) and the second electrode (355-2).

[0102] The processor (220, 310) can measure (or extract) biometric characteristics (e.g., waveforms, waveform features, heartbeat patterns, etc.) from an ECG signal generated by contact between two hands. For example, an ECG signal is biometric information with unique characteristics that can be distinguished from each individual user, and can be used as information that can identify the user.

[0103] In operation 530, the processor (220, 310) can determine whether the user is a registered user based on the measured biometric characteristics.

[0104] For example, the processor (220, 310) can compare the measured biometric characteristics with the biometric characteristics of the registered user stored (or registered) in the memory to determine whether the registered user is a registered user.

[0105] In operation 540, the processor (220, 310) can complete user authentication by recognizing (or identifying) the user as a registered user (e.g., registered user) if the measured biometric characteristic is higher than a certain standard (e.g., matching rate of 90% or higher) with the stored biometric characteristic as a result of the comparison (e.g., yes in operation 530).

[0106] If recognized as a registered user, the processor (220, 310) can access all information as well as security information of the wearable electronic device (201), and can be set to allow all functions (e.g., first control level).

[0107] In operation 550, the processor (220, 310) can recognize (or identify) another user if the measured biometric characteristics are below a certain standard compared to the stored biometric characteristics. Based on the recognition of the user as another user, the processor (220, 310) can determine that the user authentication has failed, blocking access to security information and restricting functions related to security information (e.g., second suggested level).

[0108] The processor (220, 310) can control the device to operate in a power saving mode (or sleep state) or a device lock state by proceeding to operation 520 when the device is in a wearing state (e.g., yes in operation 510), and proceeding to operation 560 when the device is in a detached state (e.g., no in operation 520).

[0109] FIG. 6 is a drawing illustrating a user registration method of a wearable electronic device according to one embodiment.

[0110] Referring to FIG. 6, an electronic device (101) and a wearable electronic device (201) according to one embodiment can be linked to each other to support a function of registering a user wearing the wearable electronic device (201) using various user recognition methods (e.g., mobile linkage recognition, ECG recognition, gesture / pattern recognition), a function of registering multiple registered users, and a function of setting allowable functions differently for each user recognition method.

[0111] The electronic device (101) can perform a series of operations to register a user wearing the wearable electronic device (201) while being paired with the wearable electronic device (201). The electronic device (101) and the wearable electronic device (201) can transmit and receive various data and / or signals through the communication module (210).

[0112] In operation 610, the electronic device (101) may display a user interface guiding the user wearing the wearable electronic device (201) in recognition mode and registration settings on the display and enter a setting mode. The user interface guiding the user in recognition mode and registration settings may include items guiding the user in recognition mode and registration processes and setting the user recognition mode.

[0113] In operation 620, the electronic device (101) can determine the user recognition method and registration items based on the user's selection input.

[0114] In operation 630, the electronic device (101) can guide the ECG recognition method (e.g., information to contact both hands to the ECG electrodes) based on the input for selecting the ECG recognition method being detected.

[0115] In operation 635, the electronic device (101) may receive an ECG signal generated from the ECG electrodes of the wearable electronic device (201) and store a registered user for distinguishing the user based on the biometric characteristics (e.g., ECG information) included in the ECG signal. The electronic device (101) may transmit the user identification information of the registered user to the wearable electronic device. For example, user #1 may be stored as a user registered through ECG recognition, and the user identification information of user #1 (e.g., #1 - ECG recognition method, ECG biometric characteristics) may be transmitted to the wearable electronic device (201).

[0116] In operation 640, the electronic device (101) may guide a mobile linkage recognition method (e.g., information to register a mobile device with a wearable electronic device and contact both hands to ECG electrodes) based on the input detecting the selection of a mobile linkage recognition method.

[0117] In operation 645, the electronic device (101) can store a registered user based on biometric characteristics (e.g., ECG information) and device identification information included in an ECG signal measured from the ECG electrodes of the wearable electronic device (201).

[0118] The electronic device (101) can exchange device identification information (e.g., a token) for device identification with the wearable electronic device (101) through a communication module. The wearable electronic device (201) can register / store the electronic device (101) based on the device identification information.

[0119] For example, user #1 is stored as a user registered by mobile linkage recognition method, and user identification information of user #1 (e.g., #1 - mobile linkage recognition method, ECG biometric characteristics, and #1 device identification information) can be transmitted to the wearable electronic device (201).

[0120] For another example, if user #1 and another user #2 register using the mobile linkage recognition method, user identification information of user #2 may include, for example, #2 - mobile linkage recognition method, ECG biometric characteristics, and #2 device identification information.

[0121] In operation 650, the electronic device (101) can guide a gesture / pattern recognition method (e.g., action information for a specific gesture using a wearable electronic device) based on the input that selects the gesture / pattern recognition method being detected.

[0122] In operation 655, the electronic device (101) can store a registered user based on gesture / pattern information utilizing the wearable electronic device (201). For example, the electronic device (101) and the wearable electronic device (201) can recognize a gesture utilizing the wearable electronic device (201) and store a registered user based on the recognized gesture information. When the #3 user registers using the gesture / pattern recognition method, the user identification information of the #3 user can include, for example, #3 - gesture / pattern recognition method and gesture information.

[0123] According to one embodiment, the wearable electronic device (201) may identify a registered user and maintain user authentication of the authenticated user until a preset validity period or validity condition is maintained. For example, if the wearable electronic device (201) is authenticated after identifying the registered user at the time of mounting, the user authentication of the registered user may remain valid until the wearable electronic device is switched to a detached state. In another example, the wearable electronic device (201) may maintain user authentication for the authenticated registered user at the time of mounting the wearable electronic device while it is connected to the electronic device (101).

[0124] According to one embodiment, the wearable electronic device (201) can set allowable functions differently depending on the user recognition method as shown in Table 1 below.

[0125] User recognition method / control method Allowable control function group Mobile link recognition (e.g., first control level) First function that allows access to secure information (e.g., pay, door lock, car key) ECG recognition (e.g., second control level) Second function related to biometric information (e.g., health data) Gesture / pattern recognition (e.g., third control level) Third function related to device control (e.g., device control)

[0126] For example, if a user wearing the wearable electronic device (201) is a user identified and authenticated through mobile linkage recognition, the wearable electronic device (201) may allow all of the first, second, and third functions. If a user wearing the wearable electronic device (201) is a user identified through ECG recognition, the wearable electronic device (201) may block the first function and allow only the second and third functions. If a user wearing the wearable electronic device (201) is a user identified through gesture / pattern recognition, the wearable electronic device (201) may block the first and second functions and allow only the third function.

[0127] FIG. 7 illustrates a user recognition operation method of a wearable electronic device according to one embodiment.

[0128] Referring to FIG. 7, according to one embodiment, the wearable electronic device (201) may support a function that sets different user recognition methods for each function. For example, in the case of a door unlocking function using the wearable electronic device (201), the function may be set to be executed only when the user is authenticated using a mobile linkage recognition method.

[0129] In operation 710, the processor (220, 310) of the wearable electronic device (201) may detect a first function execution request.

[0130] In operation 720, the processor (220, 310) can determine whether a user wearing the wearable electronic device (201) (hereinafter, wearer) is an authenticated user in a user recognition method set in the first function.

[0131] The processor (220, 310) measures biometric characteristics based on ECG signals measured through the first electrode and the second electrode when the wearable electronic device (201) is worn, compares the measured biometric characteristics with biometric characteristics stored in the memory, and identifies whether the wearer is a registered user or another user, and completes user authentication if the wearer is identified as a registered user.

[0132] For example, the first function may be configured to allow only registered users authenticated via mobile linkage recognition. If the measured biometric characteristics are similar to the biometric characteristics of user #2 stored via mobile linkage recognition, the wearable electronic device (201) may identify the wearer as a registered user and complete user authentication of user #2.

[0133] In operation 730, the processor (220, 310) may determine whether the first function requires interfacing with the mobile device (or electronic device (101)) if the wearer is an authenticated user in the user recognition method set for the first function (yes in operation 720).

[0134] In operation 740, the processor (220, 310) can execute the first function if the wearer is a user authenticated by the user recognition method set in the first function and the first function does not require mobile linkage (no in operation 730).

[0135] In operation 750, the processor (220, 310) can determine whether the wearer is a user authenticated by the user recognition method set in the first function and is connected to a mobile device (e.g., electronic device (101)) if the first function requires mobile linkage (yes in operation 730).

[0136] In some embodiments, operations 730 and 750 may be omitted. For example, if operation 730 is omitted, the processor (220, 310) may execute the first function by skipping operations 730 and 750 and proceeding to operation 740, since the user is a user authenticated by the user recognition method set in the first function and the user is a user authenticated by the mobile linkage recognition method through mobile token exchange, and the mobile authentication has already been completed at the time of ECG registration.

[0137] If the processor (220, 310) is connected to a mobile device (e.g., electronic device (101)) (yes in operation 750), the processor can proceed to operation 740 to execute the first function.

[0138] The processor (220, 310) may proceed to operation 760 to block (or restrict) execution of the first function if the wearer is a user authenticated by the user recognition method set for the first function and the first function requires mobile linkage, but is not connected to a mobile device (e.g., electronic device (101)) (no in operation 750).

[0139] In operation 760, the processor (220, 310) may block (or restrict) execution of the first function if the wearer is not an authenticated user in the user recognition method set for the first function (no in operation 720).

[0140] The first function may be set to allow only registered users authenticated through mobile linkage recognition. For example, if the wearable electronic device (201) does not match the biometric characteristics stored in the memory, the wearable electronic device (201) may identify the wearer as a different user and block (or restrict) the first function. In another example, if the biometric characteristics of the wearer are similar to the biometric characteristics of user #1 stored through ECG recognition, the wearable electronic device (201) may distinguish the wearer as user #1. However, since the first function only allows registered users authenticated through mobile linkage recognition, the first function may be blocked (or restricted) if the wearer is identified as user #1.

[0141] FIG. 8 illustrates a drawing for explaining a user recognition-specific function control operation of a wearable electronic device according to one embodiment.

[0142] Referring to FIG. 8, a wearable electronic device (201) and an electronic device (101) according to one embodiment may support a key registration function to support unlocking of a door lock device (104).

[0143] For example, the door lock device (104) can register / set up a wearable electronic device (201) with a user-authenticated registered user. Looking at a series of processes for user registration, the wearable electronic device (201) may be in a state where a user wearing the wearable electronic device (201) (hereinafter, “wearer”) while connected to the electronic device (101) is authenticated as a registered user registered through mobile linkage authentication. The wearer may tag (e.g., NFC tag) the wearable electronic device (201) to the door lock device (104). The door lock device (104) may transmit key information to the NFC framework (811) of the wearable electronic device (201) through the NFC framework (821).

[0144] The wearable electronic device (201) can check the control level related to the door lock function through the action manager (813), identify the wearer through the user identification module (812), and determine whether the wearer is an allowed registered user of the door lock function. If the wearable electronic device (201) is identified as an allowed registered user of the door lock function through the user identification module (812), the wearable electronic device (201) can store the key information transmitted from the door lock device (104) as security information in the memory (230, 320). The wearable electronic device (201) can transmit a signal to the door lock device (104) indicating that the key information has been stored and registered. The door lock device (104) can output a sound or voice guide notifying that the wearable electronic device (201) and the authenticated user have been registered through the door manager service (822).

[0145] A wearer may tag a wearable electronic device (210) with a door lock device to unlock a door. The wearable electronic device (201) determines whether the wearer is a registered user permitted to use the door lock function based on a biometric characteristic measured based on an ECG signal generated at the time of wearing the device. If the wearer is identified as a registered user permitted to use the door lock function, the wearable electronic device (201) may transmit stored key information to the door lock device (104) via an NFC tag to unlock the door. If the wearer is not a registered user permitted to use the door lock function or is identified as another user, the stored key information may not be transmitted even if the wearable electronic device (201) is tagged with a door lock device.

[0146] FIG. 9 illustrates a diagram for explaining a user recognition-specific function control operation of a wearable electronic device according to one embodiment.

[0147] Referring to FIG. 9, a processor (220, 310) of a wearable electronic device (201) according to one embodiment may measure a first biometric characteristic based on a perovskite signal (or ECG signal) of a first electrode (355-1) and a second electrode (355-2) when the wearable electronic device (201) is worn in operation 910.

[0148] When a user wears a wearable electronic device (201) by holding the wearable electronic device (201) with one hand (410) and putting the wearable electronic device (201) on a finger of the other hand (415) as shown in <Fig. 4>, the wearable electronic device (201) is switched to a closed loop state because the electrodes (355-1, 355-2) are in contact with both hands at the time of wearing, and can generate an ECG signal having a biometric characteristic.

[0149] In operation 920, the processor (220, 310) can determine whether a user wearing a wearable electronic device (201) (hereinafter, wearer) is a registered user.

[0150] The processor (220, 310) can measure (or extract) biometric characteristics (e.g., waveform, waveform feature points, heartbeat pattern, etc.) from the ECG signal generated by the contact between two hands. The processor (220, 310) can compare the measured biometric characteristics with the biometric characteristics of a registered user stored (or registered) in the memory to determine whether the user is a registered user.

[0151] In operation 930, the processor (220, 310) may maintain the pre-registered user (hereinafter, “registered user”) if, as a result of the comparison, the wearer is a pre-registered user (e.g., “yes” in operation 920). For example, the processor (220, 310) may determine the wearer as a pre-registered user if the measured biometric characteristics at the time of wearing are compared with the stored biometric characteristics and are above a certain standard (e.g., a matching rate of 90% or higher).

[0152] In operation 940, the processor (220, 310) may monitor second biometric information (e.g., PPG signal) based on the user being registered. The second biometric information may be biometric information measured based on an optical biometric sensor (e.g., first sensor).

[0153] The processor (220, 310) can transmit the measured second biometric information to an electronic device (101) connected to the wearable electronic device (201) via wireless communication.

[0154] In operation 950, the processor (220, 310) can determine whether the user has been identified as a registered user but is connected to the electronic device (101) via wireless communication.

[0155] In some embodiments, operation 950 may be replaced with an operation in which the processor (220, 310) determines whether the registered user's user recognition method is a user registered using the mobile linkage authentication method, regardless of whether the electronic device is connected.

[0156] In operation 960, the processor (220, 310) can activate a first function that allows access to secure information, a second function related to biometric information, and a third function related to device control if the wearer is a registered user and connected to the electronic device (or if the user recognition method is a registered user using mobile linkage authentication) (e.g., yes in operation 950).

[0157] In operation 970, the processor (220, 310) may limit the first function and activate the second function related to biometric information and the third function related to device control if the wearer is a registered user but not connected to the electronic device (or if the user recognition method is a registered user using the ECG method) (e.g., no in operation 950).

[0158] In operation 980, the processor (220, 310) may recognize the wearer as a different user if the wearer is not a registered user (e.g., no in operation 920) based on the comparison result in operation 920, block the first and second functions, and activate only the third function related to device control.

[0159] A method for operating a function according to user identification of a wearable electronic device according to one embodiment includes a first sensor for measuring first biometric information using an optical signal and a second sensor for measuring second biometric information using the first electrode and the second electrode, and may include an operation of acquiring the second biometric information through the second sensor in response to a detection that a ring-type wearable electronic device is being worn on a user's body, an operation of comparing the second biometric information with information stored in the second memory, an operation of identifying a user wearing the wearable electronic device based on a result of the comparison, and an operation of differently setting a function executable by the wearable electronic device according to a recognition method of the identified user.

[0160] The operation of differently setting executable functions in the wearable electronic device according to one embodiment may be characterized by allowing a first function that allows access to secure information when the identified user's recognition method is the first method, and restricting the first function when the identified user's recognition method is the second method.

[0161] The first method according to one embodiment may include a mobile linkage recognition method for identifying and authenticating a registered user with a biometric characteristic based on device identification information and an ECG signal of an electronic device, and the second method may include an ECG recognition method for identifying and authenticating a registered user with a biometric characteristic based on an ECG signal.

[0162] The operation of differently setting the executable function in the wearable electronic device according to one embodiment may further include an operation of allowing a second function related to the first biometric information when the user recognition method is the second method.

[0163] In accordance with one embodiment, the third function execution request may further include an operation of executing the first function if the identified user is a user authenticated by the user recognition method set for the first function, and an operation of restricting the execution of the first function if the identified user is not a user authenticated by the user recognition method set for the first function.

[0164] The operation of acquiring the second biometric information according to one embodiment may be characterized by acquiring the second biometric signal by changing the lock state of the wearable electronic device to an unlock state based on the wearable electronic device being switched from a detached state to a mounted state.
