In order to reduce power consumption of the electronic device, avoid other people from browsing contents of the electronic device, avoid error operations caused by own error electronic devices on a display screen of the electronic device, and the like, a user can lock the electronic device on the screen.

In one implementation, a user may send a screen locking instruction to the electronic device through a screen locking key or the like provided on the electronic device, so as to control the electronic device to lock a screen.

In another implementation, if the electronic device is a wearable device, the user may lock the wearable device by removing the wearable device. The wearable device is provided with a physiological signal collector, such as a photoelectric sensor, an infrared sensor and the like, and can collect physiological signals of a user, such as physiological signals related to pulse information, physiological signals related to heart rate information, physiological signals related to eye movement information and the like, wherein the collected physiological signals can be one or more groups of physiological signals within a specified duration, and a signal curve can be drawn according to the collected physiological signals. The wearable device may provide relevant services to the user based on these physiological signals. For example: if the wearable device is a smart watch, the smart watch is provided with a photoelectric sensor, and the smart watch can collect bioelectricity generated by a user and/or blood flow in a specific time through the photoelectric sensor and obtain physiological signals of the user according to Photoplethysmography (PPG), electrocardiography (ECG), etc. According to the type of physiological signals to be acquired by the wearable device, the wearable device needs to be worn on a designated human body part so that the wearable electronic device can acquire the physiological signals of the corresponding type on the designated human body part. For example: the smart watch needs to be worn on the wrist to collect physiological signals related to pulse information, heart rate information and the like, and at this time, the wrist is a designated human body part corresponding to the smart watch. That is, the wearing device is worn on a predetermined human body part, that is, in a wearing state, and has a condition of acquiring a physiological signal of the user. If the wearing device is not worn on a designated human body part, namely, is not in a wearing state, the condition of acquiring physiological signals of the user is not provided. Further, normal services can be provided for the user only when the wearable device is in the wearing state, but not provided for the user if the wearable device is not in the wearing state. Thus, the wearable device can be configured to be unlocked when in a wearing state, and to be locked when not in a wearing state.

When the user needs to use the electronic device again, the electronic device can be awakened, namely the display screen is lightened, by clicking the display screen of the electronic device, turning over the electronic device, knocking the back shell of the electronic device, pressing the screen locking key of the electronic device, re-wearing the electronic device and the like.

If the user does not set the screen locking password for the electronic equipment, the electronic equipment is directly unlocked after being awakened. For example: the user interface displayed before closing the display screen, the desktop of the operating system, etc. are displayed directly. For the scene that the security requirement on the electronic equipment is lower, the screen locking password is inconvenient to input, the user can quickly unlock the electronic equipment by not setting the screen locking password for the electronic equipment so as to avoid the unlocking verification process after waking up the electronic equipment, thereby improving the unlocking efficiency.

As shown in fig. 2, an electronic device is taken as an example of a smart watch. When the intelligent watch is in the screen locking state, if the intelligent watch receives a wake-up instruction, the intelligent watch is directly unlocked because the intelligent watch is not provided with the screen locking password. For example, it is detected that the device is in a wearing state again, such as by detecting that the device is worn on the wrist by a person, or if a wake-up instruction input by the user by clicking a display screen or the like is received, the smart watch will unlock the device directly. If the wake-up instruction is sent by the user himself, the user can quickly unlock the intelligent watch for normal use.

As shown in fig. 2, if it is other than the user himself who sends the wake-up instruction, the other person can use the smart watch without any obstacle, for example, pay using the smart watch, which would seriously affect the security of the smart watch. In order to improve the safety of the electronic equipment, a user can set a screen locking password for the electronic equipment.

If the user sets the screen locking password for the electronic equipment, after the electronic equipment is awakened, the user needs to input the screen locking password so as to unlock the electronic equipment after the input screen locking password passes the unlocking verification. For the scene that the electronic equipment is not provided with the screen locking password, the user can unlock the electronic equipment conveniently, but once the electronic equipment is held by other people, the holder of the electronic equipment can unlock the electronic equipment directly, and the electronic equipment can be used directly. Even if the electronic device is not held by another person, it is possible for the user to misuse the electronic device by miscontacting the display screen of the electronic device to unlock the electronic device and misuse the electronic device without awareness. In order to improve the safety of the electronic equipment, a user can set a screen locking password for the electronic equipment. After the electronic equipment is awakened, the equipment can be unlocked only after the acquired screen locking password input by the user passes the unlocking verification, so that the safety of the electronic equipment is ensured through the screen locking password.

As shown in fig. 3, an electronic device is taken as an example of a smart watch. The intelligent watch detects that the intelligent watch is not in a wearing state, for example, the intelligent watch detects through the wrist separation, the intelligent watch is taken off by a user, and the electronic equipment is in a screen locking state. If the intelligent watch receives the awakening instruction, the intelligent watch displays a screen locking interface for a user to input the screen locking password for unlocking because the intelligent watch is provided with the screen locking password. For example, detecting that the user is in a wearing state again, such as by detecting that the user is wearing the wrist, or if a wake-up instruction input by the user by clicking a display screen or the like is received, the smart watch will display a lock screen interface, such as a virtual keyboard including a plurality of number keys. The user can unlock the smart watch only when the correct screen locking password is input. If the wake-up instruction is sent, the other person can be blocked by the screen locking password to unlock the intelligent watch, so that the safety of the intelligent watch is ensured.

Fig. 4 is a flowchart of a method 400 for setting a lock screen password according to an embodiment of the present application, as shown in fig. 4, the method 400 includes the following steps S401 to S402:

in step S401, the electronic device provides a password setting interface of at least one screen locking password in response to an instruction of the user to unlock the screen locking password.

In the embodiment of the application, the screen locking password refers to a password which requires a user to perform password input operation. The screen locking password comprises: digital passwords, gesture passwords, voice passwords, fingerprint passwords, face information and the like. Each screen locking password is provided with a corresponding password setting interface for setting the screen locking password by a user. For example: if the screen locking password is a digital password, the corresponding password setting interface comprises a plurality of digital keys. If the screen locking password is a fingerprint password, the corresponding password setting interface comprises a fingerprint input box.

In step S402, the electronic device receives the screen locking password set by the user.

The user sets a screen locking password on the password setting interface. For example: if the user selects the digital code as the lock screen code, the user inputs the number to be set in the code setting interface corresponding to the digital code, such as 1111. The electronic device generates a screen locking password, 1111, from the number. If the user selects the fingerprint password as the screen locking password, the user inputs the fingerprint in a password setting interface corresponding to the fingerprint password. And the electronic equipment generates a screen locking password according to the fingerprint.

In some embodiments, the user may repeat steps S401-S402 to change the lock screen password, which is not described herein.

Fig. 5 is a flowchart of a method 500 for performing unlock verification using a lock screen password according to an embodiment of the present application, as shown in fig. 5, the method 500 includes the following steps S501-S502:

in step S501, the electronic device obtains a screen locking password input by a user.

In the embodiment of the application, after the electronic device is awakened, the electronic device displays a first screen locking interface, and the first screen locking interface is used for inputting a screen locking password by a user. The first screen locking interface corresponds to a pre-stored screen locking code (screen locking code set by a user). For example: if the screen locking password is a digital password, the first screen locking interface comprises a plurality of digital keys for the user to input the numbers. If the screen locking password is a fingerprint password, the first screen locking interface comprises a fingerprint input area for a user to input a fingerprint.

The electronic equipment acquires a screen locking password input by a user through the first screen locking interface. For example: if the preset screen locking password is a digital password, after the electronic equipment is awakened, a first screen locking interface containing a plurality of digital keys is displayed, a user presses the digital keys to key the digital password, the electronic equipment detects key values input by the user through the pressure sensor, and the corresponding screen locking password is identified according to the detected key values. If the prestored screen locking password is human face information, the electronic equipment is awakened after the display screen is closed, a first screen locking interface containing a face recognition prompt (such as a recognition frame, a prompt and the like) is displayed, the user inputs the face information through the display face, the electronic equipment shoots a face picture of the user through the camera, and the screen locking password is obtained according to the shot face picture.

Step S502, the electronic equipment performs unlocking verification according to the screen locking password input by the user and the pre-stored screen locking password.

The electronic equipment verifies whether the equipment can be unlocked or not by comparing the prestored screen locking password with the screen locking password input by the user. And if the screen locking password input by the user is consistent with the pre-stored screen locking password, determining that the unlocking verification is successful, and unlocking the electronic equipment. And if the screen locking password input by the user is different from the pre-stored screen locking password, determining that the unlocking verification fails. Taking a pre-stored screen locking password as 1111 as an example for explanation, if the electronic equipment obtains that the screen locking password input by the user is 1111, the screen locking password input by the user is compared with the pre-stored screen locking password to determine that the screen locking password and the screen locking password are consistent, namely the unlocking verification is successful, and the electronic equipment is unlocked. If the electronic device obtains that the screen locking password input by the user is 1112, the screen locking password input by the user is compared with the pre-stored screen locking password, and the two are determined to be inconsistent, namely the unlocking verification fails.

Therefore, the illegal holder can be prevented from randomly unlocking the electronic equipment in a mode of setting the screen locking password, so that the safety of the electronic equipment is improved. However, as shown in fig. 3, if the user himself/herself is unlocked, the user needs to input a screen locking code for unlocking verification when unlocking the electronic device, and the process of inputting the screen locking code consumes time and effort of the user. For example: the user wants to make a call by using the electronic device in the screen locking state, and after the user wakes up the electronic device, the user needs to input the screen locking password to perform unlocking verification. After unlocking the electronic device, a call can be made using the electronic device. It can be seen that, although the screen locking password has a function of preventing others, the unlocking operation needs to consume additional effort for the user himself, and if the screen locking password input by the user is wrong (such as input error, face shielding, etc.), the user needs to repeat the process of inputting the screen locking password, thereby consuming more effort.

In order to solve the above problems, the embodiment of the present application provides an unlocking method, which sets a physiological signal of a user as authentication information of the user on the basis of setting a screen locking password for an electronic device, so as to unlock the electronic device through the physiological signal of the user. The physiological signals of the user are automatically acquired by the electronic equipment without user input, so that unlocking operation of the user can be simplified, and the safety of unlocking the electronic equipment by using the physiological signals of the user can be ensured due to the characteristics of difficulty in cracking, tampering, stealing and the like of the physiological signals of the user.

Fig. 6 is a flowchart of a method 600 for acquiring physiological signals for identity verification according to an embodiment of the present application, as shown in fig. 6, the method 600 includes the following steps S601-S602:

in step S601, the electronic device collects the physiological signal of the user in response to the instruction of the user to turn on the function of verifying using the physiological signal.

The physiological signals of the user collected by the electronic equipment at this stage are used for extracting physiological characteristics used for subsequent authentication of the user. The electronic equipment collects physiological signals of the user and is at least one of N (N is a positive integer greater than 0) physiological signals which can be collected by the electronic equipment. The type of physiological signals collected by the electronic equipment can be set by the electronic equipment or by a user. For example: the electronic device is a smart watch, and the smart watch can collect physiological signals related to heart rate information, pulse information and body temperature information. The physiological signal related to heart rate information and the physiological signal related to pulse information may be used simultaneously to generate the physiological characteristics for authentication.

The electronic device collects physiological signals of a user over a specified period of time in response to an instruction to turn on a function of using the physiological signals for verification.

In one implementation, the specified time period refers to a time period from when the electronic device receives an instruction from the user to turn on a function that uses the physiological signal for authentication. The time period refers to the time period for the electronic device to collect the preset physiological signal. Taking electronic equipment as an intelligent watch as an example for explanation: if the smart watch receives an instruction from the user to turn on the function for verification using the physiological signal, the time period is 8:00:00, the time period is 1s, and the designated time period is 8:00:00-8:00:01. The smart watch collects physiological signals of the user at 8:00:00-8:00:01.

In another implementation, the specified time period refers to a plurality of time periods during normal use by the user, beginning with the electronic device receiving an instruction to the user to turn on a function that uses the physiological signal for verification. The time period refers to the time period for the electronic device to collect the preset physiological signal. Taking electronic equipment as an intelligent watch as an example for explanation: the time when the smart watch receives an instruction of starting a function for verification by using a physiological signal from a user is 8:00:00, the time period is 1s, if the smart watch is acquired in a period of 1 hour, and the smart watch is detected to be taken off at 11:00:00, the designated time period comprises 8:00:00-8:00:01, 9:00:00-9:00:01 and 10:00:00-10:00:01. The smart watch collects physiological signals of the user in the three time periods. If the smart watch collects at a designated node, the designated node detects that the smart watch is switched from the screen locking state to the unlocking state, and the smart watch is assumed to detect that the smart watch is switched from the screen locking state to the unlocking state at 9:00:00 and 10:30:00 respectively, wherein the designated time period comprises 8:00:00-8:00:01, 9:00:00-9:00:01 and 10:30:00-10:30:01. The smart watch collects physiological signals of the user in the three time periods.

In step S602, the electronic device stores physiological characteristics corresponding to the acquired physiological signals of the user.

The electronic equipment can extract the physiological characteristics corresponding to the acquired physiological signals of the user through the physiological characteristic model, and store the physiological characteristics as a data basis for subsequent identity verification.

In one implementation, an electronic device collects a set of physiological signals and extracts physiological features of the set of physiological signals through a physiological feature model. Accordingly, the electronic device has only one set of pre-stored physiological characteristics for authentication. When unlocking verification is performed according to the physiological signals of the user, the unlocking verification is performed by matching the physiological characteristics corresponding to the collected physiological signals of the user with the set of pre-stored physiological characteristics.

In one implementation, the electronic device collects multiple sets of physiological signals and extracts physiological features corresponding to each set of physiological signals through a physiological feature model. Accordingly, the electronic device has only a plurality of pre-stored physiological characteristics for authentication. When unlocking verification is performed according to the physiological signals of the user, the unlocking verification is performed by matching the physiological characteristics corresponding to the acquired physiological signals of the user with each set of physiological characteristics in the prestored sets of physiological characteristics.

In some embodiments, the type of physiological signal acquired by the electronic device of the user matches the device type of the electronic device. Electronic devices may be categorized according to the location of wear on the human body. For example: electronic devices worn on the wrist (e.g., smart watches, smart bracelets, etc.), electronic devices worn on the head (e.g., smart helmets, etc.), electronic devices worn on the eye (e.g., VR glasses, etc.), etc., are of different types. Different types of electronic devices have different functions, and accordingly, the electronic devices have hardware structures for realizing the functions. For example: the intelligent wrist-watch possesses the function of monitoring user's heart rate information, and correspondingly, the intelligent wrist-watch possesses photoelectric sensor to gather the physiological signal that is correlated with heart rate information. For example: the intelligent helmet has an emotion relieving function, and correspondingly, the intelligent helmet is provided with a photoelectric sensor to collect bioelectricity generated by brain neurons of a user and obtain physiological signals related to the electroencephalogram (EEG) according to an electroencephalogram technology. For example: the VR glasses have an Eye control function, and correspondingly, the VR glasses have Eye trackers (Eye trackers) to collect physiological signals related to Eye movement information through the Eye trackers. Correspondingly, the electronic device can directly take the physiological signal which can be acquired by the self-configured hardware structure as the physiological signal to be acquired, namely the physiological signal for generating the physiological characteristics for identity verification. For example: the intelligent watch can collect physiological signals related to heart rate information of a user through the photoelectric sensor, and the physiological signals related to the heart rate information can be used as physiological signals for generating physiological characteristics for identity verification. Another example is: the VR glasses can collect physiological signals related to the eye movement information of the user through the eyeball tracker, and the physiological signals related to the eye movement information can be used as physiological signals for generating physiological characteristics for identity verification. Therefore, an additional physiological signal collector is not required to be configured in the electronic equipment to be specially used for collecting physiological signals corresponding to the physiological characteristics for identity verification, so that the cost of the electronic equipment can be effectively reduced, and the volume of the electronic equipment can be effectively controlled.

The method of acquiring physiological signals for authentication provided herein is further described in connection with an example.

Fig. 7 is an exemplary diagram of a method 600 of the present application for collecting physiological signals for authentication. As shown in fig. 7, this example includes step S701 to step S702, which correspond to step S601 to step S602 in the method 600 shown in fig. 6, respectively.

Take an electronic device as an example of a smart watch. In step S701, the smart watch collects a physiological signal of a user in response to an instruction of the user to turn on a function of performing authentication using the physiological signal. For example: the physiological signal of the user is obtained by PPG, ECG, etc. techniques. In step S702, the smart watch stores physiological characteristics corresponding to the acquired physiological signals, so as to use the physiological characteristics as a data base for authentication.

In some embodiments, due to the low acquisition rate of the physiological signal of the user, once the electronic device is disturbed, the acquisition of the physiological signal of the user will be affected, resulting in the inability to unlock the device. In order to ensure that the electronic equipment can be unlocked, when the electronic equipment is started to perform verification function by using a physiological signal, the electronic equipment is ensured to be unlocked not only by the physiological signal, but also by a screen locking password when the electronic equipment cannot be unlocked by the physiological signal.

Fig. 8 is a flow chart of a method 800 of the present application for collecting physiological signals for authentication. As shown in fig. 8, the method 800 includes the following steps S8011-S802. Step S802 is similar to step S602 in the method 600 shown in fig. 6, and will not be described herein. The following description is made for step S8011 to step S8013:

in step S8011, the electronic device detects whether the screen locking password exists before the user starts the function of verifying using the physiological signal in response to the instruction of the user to collect the physiological signal of the user.

In one implementation, the electronic device may detect whether there is an already stored lock screen password by querying the memory.

In one implementation, the electronic device may detect whether there is an already stored screen locking password by detecting whether the function of the screen locking password is unlocked. If the function of the screen locking password is detected, determining that the screen locking password exists. If the function of the screen locking password is detected to be not unlocked, the screen locking password is determined to be absent.

In step S8012, if the screen locking password does not exist, the electronic device displays a prompt, and after detecting that the user inputs the screen locking password, the physiological signal of the user is collected.

The prompt is used for prompting the user to set the screen locking password. For example: please set the lock screen password first. The process of setting the screen locking password is similar to the process of step S401-step S402, and will not be described here again.

After detecting that the user inputs the screen locking password, the electronic device starts to collect physiological signals of the user after detecting that the user sets the screen locking password.

Step S8013, if the screen locking password exists, the physiological signal of the user is collected.

After detecting that the screen locking password exists, the electronic equipment can directly collect physiological signals of the user.

Fig. 9 is an exemplary diagram of a method 800 of the present application for collecting physiological signals for authentication. As shown in fig. 9, this example includes steps S9011-S902, corresponding to steps S8011-S802, respectively, in the method 800 shown in fig. 8. Step S902 is similar to step S702 in the example shown in fig. 7, and will not be described herein. The following description is made for step S9011 to step S9013:

take an electronic device as an example of a smart watch. In step S9011, the smart watch detects whether a lock screen password exists in response to an instruction of the user to turn on a function for authentication using a physiological signal. In step S9012, if the smart watch detects that the screen locking password does not exist, the smart watch displays a prompt, such as "please set the screen locking password first", to prompt the user to set the screen locking password first. If the user sets a screen locking password 1111 according to the prompt, the smart watch acquires physiological signals of the user after detecting the screen locking password. In step S9013, if the smart watch detects the presence of the lock screen password "1111", the smart watch directly collects the physiological signal of the user.

In the embodiment of the application, the screen locking password and the physiological signal for verifying the identity can be simultaneously set, so that when the physiological signal cannot be used for identity verification, the user can be prevented from being influenced by unlocking the screen locking password.

The embodiment of the application also provides an unlocking method. Fig. 10 is a flowchart of an unlocking method 1000 provided in an embodiment of the present application. As shown in fig. 10, when the electronic device sets the screen locking password and the physiological signal as the authentication information, the method 1000 may include the following steps S1001 to S1003:

in step S1001, the electronic device obtains authentication information of the user after being awakened.

The authentication information includes: a screen lock password entered by a user or a physiological signal of the user. Wherein the physiological signal of the user is acquired after the electronic device determines that the condition for acquiring the physiological signal of the user is present.

The electronic device can acquire the screen locking password input by the user at any time after being awakened, namely, the user can select to unlock the electronic device through the screen locking password. The electronic device at any time after being awakened, including: before detecting whether the condition for acquiring the physiological signal of the user is met, in the process of detecting whether the condition for acquiring the physiological signal of the user is met or not, or after detecting whether the condition for acquiring the physiological signal of the user is met (determining that the condition for acquiring the physiological signal of the user is met or the condition for acquiring the physiological signal of the user is not met). For example: the electronic device displays the first lock screen interface after being awakened, and the process may refer to step S301, which is not described herein. Thus, the user may choose to directly enter the lock screen password after the electronic device is awakened.

After the electronic device is awakened, if the condition for acquiring the physiological signal of the user is detected, the electronic device acquires the physiological signal of the user.

In some embodiments, the electronic device may detect whether it is in a worn state by a photoelectric sensor and/or an infrared sensor, or the like. If the electronic device detects a wearing state, already worn on the body of the user, the electronic device is provided with a condition for acquiring physiological signals of the user. If the electronic device detects that the electronic device is not in a wearing state, the electronic device does not have a condition for acquiring physiological signals of the user. For example: if the smart watch detects that the smart watch is worn on the wrist of the user after being awakened, the smart watch determines that the smart watch has the condition of acquiring the physiological signal of the user. If the smart watch detects that the smart watch is not worn on the wrist of the user after being awakened, the smart watch determines that the condition for collecting the physiological signals of the user is not met.

If the electronic equipment detects the condition with the function of collecting the physiological signals of the user, the electronic equipment automatically collects the physiological signals of the user as the identity verification information. After the electronic device detects the condition of acquiring the physiological signals of the user, the physiological signal acquisition devices which are used for generating the physiological signals corresponding to the pre-stored physiological characteristics are started to acquire the corresponding physiological signals through the physiological signal acquisition devices. Therefore, the electronic equipment can be prevented from occupying other signal collectors, physiological signals irrelevant to pre-stored physiological characteristics can be prevented from being collected by the electronic equipment, and the collection precision of the physiological signals of the user is improved.

After the electronic equipment acquires the screen locking password input by the user or acquires the physiological signal of the user, the electronic equipment stops acquiring the other type of identity verification information and performs unlocking verification by using the acquired identity verification information.

Step S1002, if the electronic device acquires the screen locking password, unlocking verification is performed according to the screen locking password.

Step S1002 is similar to step S301-step S302, and will not be described here.

In step S1003, if the electronic device acquires the physiological signal of the user, the unlocking verification is performed according to the physiological signal of the user.

The electronic equipment extracts corresponding physiological characteristics according to the acquired physiological signals of the user, and performs unlocking verification by calculating the matching degree of the physiological characteristics and the physiological characteristics stored in advance. If the matching degree of the physiological characteristics corresponding to the acquired physiological signals of the user and the pre-stored physiological characteristics is larger than or equal to a preset threshold value, the electronic equipment determines that the unlocking verification is successful, and unlocks the electronic equipment. If the matching degree of the physiological characteristics corresponding to the acquired physiological signals of the user and the pre-stored physiological characteristics is smaller than a preset threshold, the electronic equipment determines that unlocking verification fails.

In some embodiments, to improve the efficiency and accuracy of the unlocking verification, the unlocking verification may be performed by a physiological feature model. The physiological characteristic model may be a convolutional neural network (Convolutional Neural Networks, CNN) model or the like. The electronic equipment builds the physiological characteristic model in advance so as to directly use the physiological characteristic model for unlocking verification after the physiological signal of the user is acquired.

The electronic device can train the physiological characteristic model through the sample data. The physiological signal in the sample data may be a physiological signal collected by the electronic device after the electronic device responds to an instruction of the user to start a function of verifying using the physiological signal, or may be a physiological signal collected by the electronic device during normal use by the user. After the physiological characteristic model is constructed, the electronic equipment can iteratively train the physiological characteristic model according to the physiological signal used during unlocking and the corresponding unlocking verification result so as to improve the unlocking verification precision of the physiological characteristic model.

The process of unlocking and verifying the electronic equipment through the physiological characteristic model can be as follows: the electronic equipment inputs the collected physiological signals into a physiological characteristic model, and the physiological characteristic model firstly carries out filtering and denoising treatment on the physiological signals so as to improve the quality of the physiological signals and further improve the accuracy of matching calculation. The physiological characteristic model performs characteristic extraction processing on the physiological signals after noise reduction to extract characteristic vectors of the physiological signals, and performs fusion processing on the extracted characteristic vectors to obtain physiological characteristics corresponding to the acquired physiological signals. For example: if multiple feature vectors are included, fusion processing may be performed according to the weight values. The physiological characteristic model calculates the matching degree of the physiological characteristic and each pre-stored physiological characteristic, and compares the calculated matching degree with a preset threshold value to determine whether the acquired physiological signal can pass verification.

Fig. 11 is an exemplary diagram of an unlocking method 1000 provided in an embodiment of the present application. As shown in fig. 11, this example includes steps S1101 to S1103, which correspond to steps S1001 to S1003, respectively, in the method 1000 shown in fig. 10.

As shown in fig. 12, an electronic device is taken as a smart watch, and a pre-stored screen locking password is taken as a digital password "1111" for illustration. The intelligent watch detects that the intelligent watch is not in a wearing state, for example, the intelligent watch detects through the wrist separation, the intelligent watch is taken off by a user, and the electronic equipment is in a screen locking state.

In step S1101, after the smart watch is awakened, if the presence of the screen locking password is detected, the smart watch will start the process of unlocking by the screen locking password or unlocking by the physiological signal of the user, i.e. the smart watch acquires the screen locking password input by the user or the physiological signal of the user. Before starting a process of unlocking through physiological signals of a user, the intelligent watch firstly detects whether conditions for acquiring the physiological signals of the user exist. For example: the smart watch may detect whether it is in a worn state by a photoelectric sensor and/or an infrared sensor or the like.

In step S1102, if the smart watch acquires the screen locking password input by the user, the smart watch performs unlocking verification on the screen locking password. For example, the smart watch performs unlocking verification by comparing whether the screen locking password is consistent with a pre-stored screen locking password "1111". For example: if the acquired screen locking password is 1111, the acquired screen locking password is consistent with the screen locking password stored in advance, the unlocking verification is successful, and the intelligent watch is unlocked, so that a user can unlock the intelligent watch through the screen locking password. If the acquired screen locking password is 1112, the screen locking password is inconsistent with the pre-stored screen locking password, and the unlocking verification fails, the intelligent watch is in the screen locking state continuously, and thus, other people can be effectively prevented from unlocking the intelligent watch through the screen locking password.

In step S1103, if the smart watch acquires the physiological characteristics of the user, the smart watch may input the physiological characteristics of the user into a physiological characteristic model constructed in advance to perform unlocking verification. For example: if the unlocking verification result of the physiological characteristic model is that the unlocking verification is successful, the intelligent watch can unlock the equipment without additional unlocking operations, such as inputting a screen locking password and the like, by a user, so that the unlocking operation of the user can be effectively simplified. If the unlocking verification result of the physiological characteristic model is that the unlocking verification fails, the intelligent watch is in a screen locking state continuously, and therefore safety of the intelligent watch is guaranteed.

In the embodiment of the application, if the electronic equipment has the condition of collecting the physiological signals of the user, the electronic equipment can be unlocked as long as the collected physiological signals pass verification, and the user does not need to perform the input operation of the screen locking password, so that the user operation can be effectively simplified, and the unlocking convenience is improved. Moreover, the physiological signal of the user has higher safety, and the safety of the electronic equipment for unlocking the equipment only after the physiological signal of the user passes verification can be effectively ensured.

The embodiment of the application also provides an unlocking method. Fig. 13 is a flowchart of a method 1300 of acquiring a physiological signal of a user provided in an embodiment of the present application. As shown in fig. 13, the method 1300 includes steps S1301-S1303:

In step S1301, after the electronic device is awakened, if the electronic device determines that the condition for collecting the physiological characteristics of the user is provided, the electronic device determines whether the electronic device is in a stationary state.

The electronic device may be detected by an adaptive cruise control (Adaptive Cruise Control, ACC) sensor.

In step S1302, if in a stationary state, the electronic device collects physiological signals of the user.

Step S1302 is similar to the process of the electronic device acquiring the physiological signal of the user in step S1001, and will not be described herein.

In step S1303, if in the motion state, the electronic device displays a prompt to prompt the user to put the electronic device in the stationary state, and after detecting that the electronic device is in the stationary state, the physiological signal of the user is collected.

If the electronic device is in motion, in one implementation, it may be considered that unlocking verification using the user's physiological signal fails.

In another implementation, the electronic device may display a prompt on the display screen to prompt the user to make the electronic device in a stationary state, and periodically perform step S1301 to collect the physiological signal of the user after detecting that the electronic device is in the stationary state, so as to perform unlocking verification through the physiological signal of the user.

Step S1003 is performed after step S1302 or step S1303. Therefore, the user can unlock the electronic equipment continuously through the physiological signal by only keeping a short stationary state, and the user can still ensure the operation convenience of the user without carrying out the input operation of the screen locking password.

Fig. 14 is an exemplary diagram of an unlocking method 1300 provided in an embodiment of the present application. As shown in fig. 14, this example includes steps S1401 to S1403, which correspond to steps S1301 to S1303 in the method 1300 shown in fig. 13, respectively. The following specifically describes step S1401 to step S1403:

in step S1401, after the smart watch is awakened, if it is determined to be in the wearing state, the smart watch determines whether or not it is in the stationary state.

For example: after determining to be in the wearing state, the smart watch activates the ACC sensor and detects whether to be in the stationary state through the ACC sensor.

Step S1402, if the smart watch is in a stationary state, collecting physiological signals of the user.

In step S1403, if the smart watch is in a motion state, the smart watch displays a prompt, such as "please not move the watch", to prompt the user to keep the smart watch in a stationary state. After detecting that the smart watch is in a static state, the smart watch collects physiological signals of the user.

Step S1103 is executed after step S1402 or step S1403.

In the embodiment of the application, the electronic equipment can ensure the validity and the accuracy of the collected physiological signals by collecting the physiological signals of the user in the static state so as to ensure the accuracy of unlocking verification and further effectively ensure the safety of the electronic equipment.

The embodiment of the application provides an unlocking method. Fig. 15 is a flowchart of an unlocking method 1500 provided in an embodiment of the present application. As shown in fig. 15, the method 1500 includes steps S1501-S1504. Step S1501 to step S1503 are similar to step S1001 to step S1003 in the method 1000 shown in fig. 10, and will not be described here. After step S1503, the following steps are also included:

in step S1504, if the electronic device fails to unlock and verify, the electronic device displays a prompt message to prompt the user to input a screen locking password.

If the electronic device fails to acquire the physiological signal of the user, for example: the physiological signals acquired by the electronic equipment are null values, discontinuous and the like. Alternatively, the electronic device uses the physiological signal of the user to unlock the authentication failure. The electronic device may prompt the user to enter a screen locking code to unlock by the screen locking code. For example: the electronic device may display a prompt, such as "please enter a screen lock code," to prompt the user for the need to unlock with the screen lock code. The procedure of the electronic device for obtaining and verifying the screen locking password is similar to that of step S501-step S502, and will not be repeated here.

Fig. 16 is an exemplary diagram of an unlocking method 1600 provided by an embodiment of the present application. As shown in fig. 16, this example includes step S1601 to step S1604, which correspond to step S1501 to step S1504 in the method 1500 shown in fig. 15, respectively. Step S1601 to step S1603 are similar to step S1101 to step S1103 in the example shown in fig. 11, and are not described here. After step S1603, the following steps are further included:

step S1604, if the smart watch fails to unlock the authentication using the collected physiological signal. The intelligent watch displays a prompt, such as 'please input a password to unlock', so as to prompt a user to unlock with a screen locking password. At this point, the smart watch begins to acquire and verify the screen locking password entered by the user.

In the embodiment of the application, the electronic equipment can be unlocked through the screen locking password when the physiological signal of the user cannot be used for unlocking, so that the unlocking rate of the electronic equipment is ensured, and the normal use of the user is prevented from being influenced.

The embodiment of the application also provides an unlocking method. Fig. 17 is a flowchart of an unlocking method 1700 provided in an embodiment of the present application. As shown in fig. 17, the method 1700 includes steps S1701-S1704. Step S1701 to step S1703 are similar to step S1001 to step S1003 in the method 1000 shown in fig. 10, and are not described here. After step S1701, the following steps are further included:

In step S1704, if the electronic device does not have the condition for acquiring the physiological signal of the user, the electronic device displays a prompt to prompt the user to input the screen locking password.

If the electronic device does not have the condition of acquiring the physiological signal of the user, for example, the electronic device detects that the electronic device is not in a wearing state, the electronic device cannot acquire the physiological signal of the user, that is, the electronic device cannot use the physiological signal of the user for unlocking verification.
