Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

first embodiment

Referring to FIG. 1, FIG. 1 is a flowchart of a method for detecting loss of a mobile terminal provided in an embodiment of the present invention, as shown in FIG. 1, comprising the following steps:

Step 101, acquire state information of a mobile terminal, where the state information includes at least two state parameter values.

The mobile terminal loss detection method provided by the embodiment of the present invention is mainly applied in the mobile terminal to monitor the loss probability of the mobile terminal, and can perform different protection operations under different loss probabilities.

In this step, the user can preset state parameters according to the actual situation. When detecting the loss of the mobile terminal, the state parameters preset by the user are acquired first. Then the current state parameter value of the mobile terminal is correspondingly acquired according to the state parameter, so as to obtain the state information of the mobile terminal.

The types of the above state parameters can be set according to actual needs, for example, different state parameters can be set according to some characteristics of the user when using the mobile phone and the user's own usage habits, which will be described in detail below.

Further, the number and sum of the state parameters can be set according to actual needs. In this embodiment, two or more state parameters are used, so that the probability of cell phone loss can be judged from a multi-dimensional direction, thereby improving cell phone loss probability. Accuracy of loss detection.

In this step, the state parameters corresponding to the mobile terminal are detected in real time, and the parameter value corresponding to each state parameter is obtained. Since the types of each state parameter are different, the corresponding detection methods are also different. For example, when the spatial angle information of the mobile terminal is used as the state parameter, the spatial angle value of the mobile terminal can be detected by the gyroscope preset in the mobile terminal; when the holding position information of the mobile terminal is used as the state parameter, it can be detected When the screen is off, the user touches the coordinate position on the touch screen to obtain the holding position information.

Each state parameter is preset with a corresponding probability value, and the probability values corresponding to multiple state parameters may be independent of each other, or may be correlated with each other. The probability values corresponding to multiple state parameters are independent of each other, which means that the probability values corresponding to multiple state parameters can be set independently without being affected by the probability values corresponding to other state parameters; the probability values corresponding to multiple state parameters are related to each other, which is It means that the probability values corresponding to multiple state parameters restrict each other, for example, it is necessary to set the probability values corresponding to multiple state parameters within a preset range. Since each parameter value has a certain timeliness, in order to improve the accuracy of the loss probability calculation, when calculating the loss probability of the mobile terminal, it is optional to perform periodic calculations, and the calculation is performed at each cycle time The probability value of the state parameter value corresponding to each state parameter in . That is, the status information of the above-mentioned mobile terminal is specifically: the status information of the mobile terminal within a preset time period.

Step 102, respectively judge whether the state parameter values in the state information satisfy their respective corresponding preset conditions, and calculate the loss probability of the mobile terminal according to the probability values corresponding to the state parameter values satisfying the preset conditions.

In this step, the loss probability of the mobile terminal in the multi-dimensional state can be calculated according to the probability value corresponding to each state parameter value obtained through detection. It can be understood that the above preset conditions can be set according to actual needs, for example, different probability values can be set for different state parameter values of the same state parameter, and the preset conditions are described in detail in the following embodiments. The calculation method of the loss probability of the mobile terminal may be set according to actual needs. For example, the loss probability of the mobile terminal can be obtained by cumulative calculation according to the corresponding probability values of each state parameter value; in addition, corresponding weight values can also be set according to the importance of each state parameter, and then according to the weight value corresponding to each state parameter. After the probability values of the state parameters are weighted and calculated, they are accumulated and calculated to obtain the loss probability of the mobile terminal.

Step 103, perform corresponding operations according to the loss probability of the mobile terminal.

In this step, different protection levels can be set according to the loss probability of the mobile terminal. When the loss probability is higher, the corresponding protection level is higher, and the loss protection operation is performed more vigorously.

Specifically, the protection operation content performed on the terminal may be set according to actual needs, for example, a corresponding operation interface may be provided for the user to set different protection operation content. The protection operation may include backing up user data of the mobile terminal, locking the mobile terminal, sending location information, encrypting and clearing user data in the mobile terminal, and the like.

In the embodiment of the present invention, the above method can be applied to any electronic device with the function of displaying and installing application programs, such as: mobile phone, tablet computer (Tablet Personal Computer), laptop computer (LaptopComputer), personal digital assistant (personal digital assistant) , referred to as PDA), mobile Internet device (Mobile Internet Device, MID) or wearable device (Wearable Device) and so on.

In this way, in the embodiment of the present invention, the state information of the mobile terminal is obtained, and the state information includes at least two state parameter values; whether the state parameter values in the state information meet the respective preset conditions is judged respectively, and according to the satisfaction The probability value corresponding to the state parameter value of the preset condition is used to calculate the loss probability of the mobile terminal; and a corresponding operation is performed according to the loss probability of the mobile terminal. Since the present invention uses multi-dimensional state parameters to judge the loss probability of the mobile terminal, the accuracy of the loss detection of the mobile terminal is improved.

second embodiment

Based on the first embodiment of the mobile terminal loss detection method of the present invention, in the second embodiment, the above step 103 includes:

When the loss probability of the mobile terminal is greater than a first preset value, backing up user data in the mobile terminal;

When the loss probability of the mobile terminal is greater than a second preset value, lock the mobile terminal, and send the location information of the mobile terminal to a server or a preset mailbox;

Encrypting or clearing user data in the mobile terminal when the loss probability of the mobile terminal is greater than a third preset value;

Wherein, the second preset value is greater than the first preset value and smaller than the third preset value.

In this embodiment, the above-mentioned first preset value, second preset value and third preset value can be set according to actual needs, specifically, the above-mentioned second preset value is greater than the first preset value and less than The third preset value, that is, the first preset value, the second preset value and the third preset value increase sequentially. For example, the first preset value may be 50%, the second preset value may be 80%, and the third preset value may be 90%. In addition, in other embodiments, other setting methods may also be used, for example, other number of levels may be set, or other protection operations may be performed, which will not be listed here.

It should be noted that the user data for backing up the user data may be the data backed up by the system by default, or the user data that needs to be backed up may be set for the user. Specifically, when the loss probability of the mobile terminal reaches the above-mentioned first preset value, the user data to be backed up may be backed up to the server or a designated mailbox.

Further, the mobile terminal can be locked by an account password. The account password may be the password of an account specified by the user. When the user needs to unlock the account, the user needs to input the account name and account password to unlock the account. Since the account password is set to lock the mobile terminal, the security of the mobile terminal lock is improved.

Further, when the loss probability of the mobile terminal reaches the above-mentioned second preset value, the location information of the location module for the location of the mobile terminal can also be obtained, and the location information can be sent to the server or preset mailbox through the network; thus Know the approximate location where the mobile terminal is lost. It can be understood that sending the location information of the mobile terminal to the server or the preset mailbox needs to be operated when the mobile terminal is connected to the Internet. If the mobile terminal cannot be connected to the network, it will not be able to locate and send the location information.

Further, the aforementioned encryption of user data refers to data encryption to prevent others from bypassing the password to unlock and directly access the user data of the mobile terminal, thereby further preventing leakage of user data and improving the security of the mobile terminal. At the same time, data can also be cleared directly to avoid data leakage. It should be noted that when the encryption or clearing operation is performed, it may be only the user data set for the user, or it may be the default user data of the system, which will not be further limited here.

Further, the type of the above-mentioned state parameter value can be set according to actual needs. In this embodiment, optionally, the above-mentioned at least two state parameter values include at least two of the following contents: the spatial angle information of the mobile terminal , holding position information, touch pressure information, step counting data, restart time, hardware button press information, application usage status information, wifi connection information, user identification card status information, geographic location information, fingerprint unlock information, password unlock information, Gesture unlock information and inactivity time.

In order to better illustrate the present invention, the mobile phone is taken as an example below to describe the preset conditions and probability values corresponding to each state parameter value in detail:

When the type of the state parameter value includes space angle information, the state of the three-dimensional space of the mobile phone can be detected through the gyroscope preset in the mobile phone to obtain the three-dimensional space angle value. Since everyone holds a mobile phone at an angle that actually has a range, the mobile phone regularly records the three-dimensional angle data of the mobile phone and calculates the variance of these data. After a long time, this value can reach a stable range. When another person uses it, such data will produce large fluctuations (that is, the fluctuation range can be a preset condition), and it can be determined that the current user may not be the owner of the mobile phone, and the probability of losing the mobile phone can be determined to be 5%. .

When the type of the state parameter value includes the holding position information, it can be detected that the user touches the coordinate position on the touch screen in the screen-off state, and then the holding position information can be obtained. Specifically, when the screen is off, people hold the mobile phone, and generally the thumb is on the screen. At this time, because the length of the finger is different from the physiological habits of each person, the coordinates of the finger touching the screen are different. Through a period of data collection, the average coordinate position of the owner is in a fixed area. When five consecutive touch positions are not in this area (that is, the number of consecutive touch positions in a fixed area is a preset condition), you can The probability value of determining that the mobile phone is lost is 10%.

When the type of the state parameter value includes touch pressure information, the pressure value pressed by the user on the touch screen may be acquired, so as to obtain the touch pressure information. Specifically, the pressure of each person's touch is also different. Through a period of data collection, an average pressing pressure can be obtained. preset condition), then it can be determined that the probability of losing the mobile phone is 10%.

When the type of the state parameter value includes step counting data, the user's walking speed can be calculated by combining the time with the internal pedometer of the mobile phone. Through a period of data collection, the user's average walking speed can be obtained. When a large change in walking speed is found (that is, the range of step counting data is a preset condition), the probability of losing the mobile phone can be determined to be 20%.

When the type of the state parameter value includes the restart time, the restart time of the mobile phone can be checked. When the mobile phone restarts, but the restart time is not the usual restart time of the owner, such as turning off the phone before going to bed at night, and turning it on in the morning or during a nap (that is, the boot time is a preset condition), then the probability of losing the phone can be determined to be 10%. .

When the type of the state parameter value includes hardware button press information, the press state of each hardware button can be detected. For example, a mobile phone generally has multiple physical buttons: a menu button, a home button, and a return button. The buttons that users often press are generally fixed, but when it is detected that a button that is not pressed for a long time has been clicked 5 times in a short period of time (that is, the usage of the button is the default condition), the probability value of the lost mobile phone can be determined 20%.

When the type of the status parameter value includes application usage status information, the usage of the application can be detected. Since the application habits used by each user are also different, when 3 infrequently used applications are activated (that is, the usage of the application is a preset condition), it can be determined that the probability of losing the mobile phone is 20%.

When the type of the state parameter value includes wifi connection information, the connection state of WiFi can be detected. When the mobile phone joins a new wifi (that is, the usage of the wifi is the default condition), it can be determined that the probability of the mobile phone being lost is 30%.

When the type of the state parameter value includes the state information of the user identification card, the state information of the mobile phone card can be detected. When the phone card of the mobile phone is pulled out or replaced (that is, the usage of the phone card is a preset condition), it can be determined that the probability of losing the phone is 30%.

When the type of the state parameter value includes geographical location information, the current location information of the mobile phone can be detected. When the geographical location of the mobile phone deviates from the usual location by a large distance (that is, the location of the mobile phone is a preset condition), the mobile phone can be determined to be lost. The probability value is 30%.

When the type of the state parameter value includes fingerprint unlocking information, the number of wrong input of fingerprint unlocking can be detected (ie, the fingerprint unlocking status is a preset condition). When the first fingerprint unlocking is wrong, the probability of losing the phone is 10%; when the second fingerprint unlocking is wrong, the probability of losing the phone is 20%; when the third fingerprint unlocking is wrong, the phone is lost The probability value of the mobile phone is 40%; when the fourth fingerprint unlocking is wrong, the probability value of determining that the mobile phone is lost is 50%.

When the type of the state parameter value includes password unlocking information, the number of wrong password unlocking input times may be detected (that is, the password unlocking status is a preset condition). When the password is unlocked wrongly for the first time, the probability of losing the phone is 10%; when the password is unlocked for the second time, the probability of losing the phone is 20%; when the password is unlocked for the third time, the phone is lost The probability value of the mobile phone is 40%; when the password is unlocked incorrectly for the fourth time, the probability value of the lost mobile phone is 50%.

When the type of the state parameter value includes gesture unlocking information, the number of times the gesture unlocking is entered incorrectly (that is, the gesture unlocking status is a preset condition) may be detected. When the first gesture unlocking is wrong, the probability of losing the phone is 10%; when the second gesture is wrong, the probability of losing the phone is 20%; when the third gesture is wrong, the phone is lost The probability value of is 40%; when the fourth gesture unlocking is wrong, the probability value of determining that the mobile phone is lost is 50%.

When the type of the state parameter value includes the static time (that is, the time when the mobile phone is not in use is a preset condition), it is possible to detect whether the mobile phone is in a static state through the gyroscope, and detect whether the mobile phone is used frequently by the user (such as during the day) for a long time still. For example, if the mobile phone is stationary for a long time during the non-night time period, and the stationary time is 1 hour, the probability value of the lost mobile phone is 10%; for each additional hour, the probability increases by 5%, reaching a maximum of 80%.

Further, the above step 102 includes:

adding the probability values corresponding to the state parameter values satisfying the preset conditions to obtain the loss probability of the mobile terminal;

or,

Multiply the probability values corresponding to the state parameter values that meet the preset conditions with the corresponding weight values to obtain the weight probability values corresponding to the state parameter values that meet the preset conditions, and the weight probability values corresponding to the state parameter values that meet the preset conditions Values are added to obtain the loss probability of the mobile terminal.

That is, in different embodiments, the method of calculating the loss probability of the mobile terminal according to the probability values corresponding to the state parameter values may directly add the probability values, or set corresponding weights to calculate the cumulative weighted value. When setting the weight value, different weight values can be set according to the importance of each state parameter value, so as to improve the accuracy of mobile terminal loss detection. Specifically, after determining the probability values of all state parameter values satisfying the preset conditions, the product of the probability values of all state parameter values and the corresponding weight values can be calculated, thereby obtaining the weight probability values of each state parameter value, and then satisfying Add the weighted probability values corresponding to the state parameter values of the preset conditions, so as to obtain the loss probability of the mobile terminal, and perform corresponding operation. Because in this embodiment, the weight calculation is set for each state parameter, the importance level of the state parameter can be set according to the use situation of each user, and the accuracy of mobile phone loss detection can be improved.
