Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the secure boot method, apparatus, and storage medium provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scenario includes a mobile terminal. The mobile terminal supports information collection (such as image information collection, sound information collection and digital information collection), information receiving and positioning and other functions. The mobile terminal may be, for example, a mobile terminal such as a smart phone, a tablet computer, a smart watch, a smart bracelet, and a PDA (Personal Digital Assistant).
Fig. 1 is a flowchart illustrating a secure boot method according to an exemplary embodiment, which is applied to a mobile terminal, as shown in fig. 1, and includes the following steps:
in step 101, it is determined whether the current environment is a hazardous state.
For example, taking a mobile terminal as an example of a smart watch, when a user uses the smart watch, the user may encounter some dangerous scenes, and may collect information (which may be at least one of image information, voice information, and data information) of a current environment in real time through devices such as a camera, a microphone, and various sensors arranged on the smart watch so as to determine whether a current state of the user is dangerous. The collected information is judged through a preset judgment mode in the mobile terminal (for example, a preset dangerous state library method can be adopted, the collected information is converted into corresponding state information, when a state matched with the state information exists in the state library, the current environment is determined to be a dangerous state), and whether the current environment is the dangerous state or not is determined.
In step 102, when the current environment is determined to be a dangerous state, guidance information for instructing the user to move to a target safety area is issued.
For example, when the current environment is determined to be a dangerous state, the current environment may be determined to be a dangerous state through a navigation system built in the mobile terminal, for example: the method comprises the steps that a Global Positioning System (GPS), a Beidou satellite navigation System, a GLONASS navigation System, a Galileo satellite navigation System and the like are used for obtaining the current position information of the mobile terminal and the position information of all preset safety regions, one of the preset safety regions is selected as a target safety region (the target safety region can be selected according to the distance from the current position of the mobile terminal), and after the target safety region is determined, the mobile terminal sends out guide information to indicate a user to move to the target safety region. The preset safety regions may be regions where the associated terminals bound to the mobile terminal are located, regions specified by the associated terminals, or safety regions preset by the mobile terminal or the associated terminals (for example, regions in police, home, school, etc.).
In summary, according to the method for guiding safely provided by the embodiment of the present disclosure, the mobile terminal first determines whether the current environment is in a dangerous state, determines whether to send out guidance information according to a result of the determination, and sends out the guidance information when the current environment is determined to be in the dangerous state, wherein the guidance information is used for instructing the user to move to the target safe area. According to the method and the device, when the user of the mobile terminal faces a dangerous scene, the user is not required to actively operate, the user can be prompted to move to a safe area in time, the safety of terminal use is improved, and the safety of the user is protected.
Optionally, the target security area includes:
and the area closest to the mobile terminal in the preset at least one preset safety area.
Step 102 comprises:
and issuing route information from the current position of the mobile terminal to the position information as the guide information according to the position information of the target safety area.
For example, the user may set at least one security zone in the mobile terminal or the server in advance, so that the mobile terminal can instruct the user to go to the security zone according to the preset security zone when the user is at risk. For example, the safety zone closest to the mobile terminal may be selected as the target safety zone by comparing the distances between the current position of the mobile terminal and all preset safety zone positions. The security area may include, for example, a preset area such as a police station, a home, and a school, an area where a related terminal bound to the mobile terminal is located, or an area specified by the related terminal. After the target safety area is determined, according to the current position of the mobile terminal and the position information of the target safety area, a route from the current position of the mobile terminal to the target safety area is planned through a navigation system arranged on the mobile terminal, and corresponding route information is sent to a user as guide information. Wherein the route information may include: the name of the target area to be traveled, the direction, route and distance from the target area to be traveled by the user, etc.
FIG. 2 is a flow diagram illustrating another secure boot method in accordance with an example embodiment. As shown in fig. 2, the mobile terminal is bound with the associated terminal, and the method further includes:
in step 103, when it is determined that the current environment is in a dangerous state, sending alarm information to the associated terminal bound with the mobile terminal, where the alarm information is used to prompt the associated terminal user that the associated terminal user is in the dangerous state.
For example, when it is determined that the current environment is in a dangerous state, an alarm message may be sent to the associated terminal through an information sending function in the smart watch to prompt that a user of the smart watch associated with the terminal is in the dangerous state, and the alarm message may include: a type in which a user using the mobile terminal is currently in a dangerous state (e.g., in a dangerous area, attracted to and forcibly carried away by a person, etc.), a current location of the mobile terminal, and a preset safety area (e.g., a police station, a school, and a home location, etc.) nearest to the current location of the mobile terminal. The associated terminal may be a mobile terminal such as a smart phone, a tablet computer, a smart watch, and a PDA, or a fixed terminal such as a desktop computer.
Fig. 3 is a flow chart illustrating one step 102 of the embodiment shown in fig. 1. As shown in fig. 3, step 102 includes the following steps:
In step 1022, route information from the current position of the mobile terminal to the target safety area is issued as the guide information.
For example, the associated terminal may send a certain designated area to the child as a target security area according to an actual requirement (for example, after the child is left to school, no one is at home, and a parent may send guidance information to the child to go to a working place of the parent through a mobile phone of a smart watch worn by the associated child), or after the associated terminal receives alarm information sent by the mobile terminal, the mobile terminal plans a route from a current position of the mobile terminal to the target security area through the navigation system after receiving the target security area, and sends corresponding route information to the mobile terminal as the guidance information, so as to guide the user to go to the designated area of the associated terminal. In addition, the priority of the target safety area can be set, for example, the priority of the target safety area sent by the associated terminal is set to be the highest and is higher than the priority of the target safety area selected by the mobile terminal, so that unreasonable guiding information sent by the mobile terminal is prevented, and the situations that the selected target area is too far and the target area is not provided with people to protect safety and the like are avoided.
Fig. 4 is a flow chart of one step 101 shown in the embodiment shown in fig. 1. As shown in fig. 4, step 101 includes the following steps:
in step 1011, target information of the current environment is obtained.
For example, target information in the current environment can be collected in real time through devices such as a camera, a microphone, and various sensors arranged on the mobile terminal, so as to determine whether the current state of the user is dangerous. The acquired target information of the current environment may include: at least one of image information, voice information, and data information. The image information, such as images of surrounding scenes and people, can be collected through the camera, the voice information, such as sounds made by surrounding people, surrounding scenes and vehicles, can be collected through the microphone, the data information can be collected through various sensors (such as an acceleration sensor, a gyroscope, a vibration sensor, and the like), such as a heart rate sensor for monitoring the heart rate of a user, and an acceleration sensor for collecting the motion information of the user.
For example, after obtaining the target information of the current environment, the target information is recognized through a preset recognition algorithm (for example, the preset recognition algorithm may include a voice recognition algorithm, an image recognition algorithm, and a data recognition algorithm), so as to obtain corresponding state information, where the state information may include: semantics, environment categories and motion states, wherein the semantics can be strangers' voice, alarms, abnormal sounds of users (such as screaming, noisy, etc.), etc., the environment categories can be roads, construction sites, river edges, etc., and the motion states can be struggling, dragging, abnormal dragging, etc. The process of identifying the target information can be executed locally, namely on the mobile terminal, or the target information can be uploaded to the server through the mobile terminal and identified by the server, so that the requirements on the computing capacity and hardware of the mobile terminal are reduced. Taking the voice information as an example, the voice information is recognized by using a preset voice recognition algorithm, for example, a DTW (Dynamic Time Warping) algorithm, the collected voice information is converted into corresponding semantics, and the semantics are used as state information.
In step 1013, when the state information matches one or more states in a preset state library, the current environment is determined to be a dangerous state.
For example, after the state information is obtained, the state information may be compared with states included in a preset state library, and it is determined whether one or more states matching the state information exist in the preset state library, if so, it is determined that the current environment is a dangerous state, and if not, it is determined that the current environment is not a dangerous state. Similarly, the judgment of whether the current environment is in a dangerous state can be performed locally on the mobile terminal or on the server, so that the judgment speed is increased. The preset state library stores preset various dangerous scenes, such as images corresponding to dangerous buildings, dangerous water areas and dangerous people, and preset various dangerous sounds, such as threatening sounds, abnormal yelling of children, luring sounds of strangers, and the like, parents can store voiceprints of the parents and trusted people in the intelligent watch and the server in advance, when the children are in contact with the people, voiceprint analysis is carried out to determine whether the children are strangers, the state library can also include preset various dangerous actions or dangerous states, such as abnormal dragging, struggling, too fast heart rate, too high blood pressure and the like, for example, acceleration signals generated by dangerous actions of the users can be collected in advance through an acceleration sensor, the acceleration signals are preprocessed, characteristics are extracted and selected, corresponding action modes are generated and stored in the intelligent watch and the server, when the user generates corresponding behaviors, the behaviors are compared with the stored behaviors to determine whether dangerous behaviors exist or not.
Optionally, the target information includes: at least one of image information, voice information, and data information.
and when the target information comprises voice information, recognizing the voice information by using a preset voice recognition algorithm so as to determine the semantics contained in the voice information.
Semantics are taken as state information.
When the target information comprises image information, the image information is identified by using a preset image identification algorithm so as to determine the environment type contained in the image information.
The context class is taken as the state information.
And when the target information comprises data information, identifying the data information by using a preset data identification algorithm so as to determine the motion state of the user contained in the data information.
The motion state is taken as state information.
For example, when the target information of the current environment is obtained as voice information, the collected voice information is converted into corresponding semantics (such as stranger's voice, alarm sound, and abnormal sound of the user) through a preset voice recognition algorithm, such as a DTW algorithm, an HMM (english: Hidden Markov model), and the like, on the mobile terminal or the server, and the semantics are used as state information.
When the target information of the current environment is acquired as image information, the acquired image information is converted into corresponding environment types (such as a road, a construction site and a river side) on a mobile terminal or a server through preset image recognition algorithms, such as a Scale-invariant feature transform (SIFT) algorithm, a FAST From Acquired Segment (FAST) algorithm, a Single tile (simple box Detector) algorithm and a Solid State Disk (SSD) algorithm, and the like, and the environment types are used as state information.
When the target information of the current environment is acquired as data information, the acquired data information is converted into corresponding motion states (such as abnormal dragging, dragging and struggling) through a preset data recognition algorithm (for example, acceleration signals when a user performs different actions can be acquired, corresponding acceleration signals are segmented according to a threshold value, the geometric characteristics of the acceleration signals are analyzed, different classifications are established for different action behaviors, the established classifications are used as the preset data recognition algorithm), and the motion states are used as state information.
Optionally, step 102 may be implemented by:
arrows or navigation information are displayed on a screen of the mobile terminal. Or,
and vibrating according to a preset vibration rule.
For example, after determining the target safety area, the mobile terminal issues the guide information instructing the user to move to the target safety area. The guiding information indicates the user to move to the target safety area by displaying an arrow or corresponding navigation information on the display screen on the route which is planned by the navigation system from the current position of the mobile terminal to the target safety area. Or, when the screen is inconvenient to see in a dangerous state (for example, a child is induced to turn by a stranger), the mobile terminal is controlled to send the guide information in a vibration mode according to a preset vibration rule in a mute state, and the vibration rule can specify the moving direction and distance according to the attributes of the vibration frequency, intensity, frequency and the like. For example, the preset vibration rule may be that one time of vibration is backward movement by one meter, two times of continuous short vibration is leftward movement by one meter, and three times of continuous short vibration is rightward movement by one meter, so as to prompt the user to leave the current dangerous state. It should be noted that the guidance information is only displayed on the screen or is prompted by vibration in a mute state of the mobile terminal, so that the user is not found by dangerous people due to the sound emitted by the mobile terminal, and the effect of guiding the user to leave the dangerous environment in a mute state is achieved, so that the concealment of the user using the mobile terminal is improved, the surrounding dangerous people are prevented from being disturbed, and the safety of the user is protected. For example, when a child avoids tracking of a stranger, the smart bracelet worn by the child can send out guide information in a silent mode, and the child is guided to leave a dangerous environment and go to a target safety area while the attention of the stranger is avoided, so that the safety of the child is protected. Furthermore, when the child does not realize entering a dangerous environment (such as a dangerous water area or a construction site), the child may not notice the guidance information on the screen in time, and the mobile terminal prompts the guidance information through vibration, so that the child can be guided to get away from the dangerous environment in time.
Optionally, the method may further include sending warning information through the mobile terminal after determining that the current environment is a dangerous state, so as to prompt a user of the mobile terminal to be away from the current environment. For example, the mobile terminal can be controlled to vibrate in a mute state, or warning information is displayed on a display screen of the mobile terminal, a warning lamp flashes, the user can be prompted to be far away from the current environment by sending out high-frequency warning sounds and the like, and the function of notifying people around the user can be achieved. The intelligent watch takes the image of the dangerous water area and the sound of the children shouting as an example, so that the current environment is judged to be a dangerous state, and the intelligent watch can send out high-frequency alarm sound to inform surrounding people to achieve the purpose of calling for help.
In summary, according to the method for guiding safely provided by the embodiment of the present disclosure, the mobile terminal first determines whether the current environment is in a dangerous state, determines whether to send out guidance information according to a result of the determination, and sends out the guidance information when the current environment is determined to be in the dangerous state, wherein the guidance information is used for instructing the user to move to the target safe area. According to the method and the device, when the user of the mobile terminal faces a dangerous scene, the user is not required to actively operate, the user can be prompted to move to a safe area in time, the safety of terminal use is improved, and the safety of the user is protected.
