In addition, stores usually use wired anti-theft systems to prevent some users from deliberately taking away devices for people to experience.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] At present, in order to better showcase their products to users, manufacturers of various electronic devices (such as smartphones, tablets, smart speakers, smart watches, etc.) usually place electronic devices on store booths for users to experience. However, when some users experience electronic devices in stores, they may take the electronic devices away, causing losses to the sellers. Therefore, stores usually take anti-theft measures for electronic devices.

[0022] In the related art, stores usually use wired ropes to prevent electronic devices from being lost, and some stores also use wireless anti-theft methods to prevent electronic devices from being stolen. Among them, wireless anti-theft methods mainly include: Radio Frequency Identification (RFID) tags, Electronic Article Surveillance (EAS), IoT sensors (such as Ultra Wide Band (UWB)), audio positioning technology, etc. In the wireless anti-theft system, the location is mainly determined by position fences or perception fences, and detectors detect alarms. However, in the related art, the risk of theft in different scenarios is different, and false alarms may occur in some scenarios, which will affect the user experience.

[0023] In view of the above problems, the inventors have proposed the device anti-theft method, apparatus, computer equipment and storage medium provided in the embodiments of the present application, which can limit the number of anti-theft alarm messages output when it is determined that the possibility of the electronic device being stolen is low, thereby reducing the number of false alarms when the electronic device is protected from theft. The specific device anti-theft method is described in detail in the subsequent embodiments.

[0024] The following first introduces the scenarios involved in the embodiments of the present application.

[0025] like Figure 1 As shown, in Figure 1 The scene shown at least includes an electronic device 10 and a signal transmitting device 20. The electronic device 10 may be a mobile phone, a tablet computer, a wearable device, a laptop computer, or the like.

[0026] In some embodiments, when the electronic device is protected from theft by using a positioning method based on wireless communication signals, the signal transmitting device 20 is a device that can transmit wireless signals into space based on wireless communication technology. The above wireless communication technology may include Bluetooth (BT) communication technology, ultra-wideband communication technology, wireless fidelity (Wi-Fi) communication technology, radio frequency identification communication technology, infrared communication, near field communication (NFC) technology, etc. Among them, the number of electronic devices 10 and signal transmitting devices 20 can be one or more ( Figure 1 Only three electronic devices and one signal transmitting device are shown).

[0027] In some embodiments, the electronic device 10 is located within the signal coverage range of the signal transmitting device 20. The electronic device 10 and the signal transmitting device 20 can transmit and receive signals based on wireless communication technology. Specifically, the signal transmitting device 20 can transmit signals into space based on wireless communication technology. If the electronic device 10 is located within the signal coverage range of the signal transmitting device 20, then it can receive the radio frequency signal transmitted by the above-mentioned signal transmitting device 20 and determine the signal strength of the radio frequency signal. Based on this, it can be determined whether the electronic device 10 is within the target range based on the signal strength of the radio frequency signal received by the electronic device 10, the positioning information of the electronic device 10, etc. If it is not within the target range, anti-theft alarm information can be output for the electronic device 10. In addition, in the process of outputting anti-theft alarm information for the electronic device 10, the electronic device 10 can also send a notification message to the signal transmitting device 20 based on wireless communication technology to inform that the current electronic device 10 has a greater risk of theft.

[0028] In some embodiments, when the audio positioning technology is used to prevent the electronic device from being stolen, the number of the signal transmitting devices 20 can be multiple ( Figure 1Only one is shown in the figure), the signal transmitting device 20 includes an audio playback module (such as a speaker, etc.), the signal transmitting device 20 can play an audio signal through the audio playback module, and the electronic device 10 collects the sound emitted by the signal transmitting device 20; according to the sound emitted by the signal transmitting device 20 at different positions collected by the electronic device 10, and using the audio positioning technology, the position of the electronic device 10 in the current environment can be determined. For example, the distance between each signal transmitting device 20 can be determined, and based on the position of the signal transmitting device 20 in the current environment and the distance between the electronic device 10 and each signal transmitting device 20 obtained, the position of the electronic device 10 in the current environment can be determined. When it is determined in the above manner that the electronic device 10 is outside the target area, anti-theft alarm information can be output for the electronic device 10.

[0029] The device anti-theft method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0030] See also Figure 2 , Figure 2 The following is a schematic diagram of a device anti-theft method provided by an embodiment of the present application. Figure 2 The process shown is described in detail, and the device anti-theft method may specifically include the following steps:

[0031] Step S110: Acquire device status information corresponding to the electronic device.

[0032] In an embodiment of the present application, when wireless anti-theft is implemented for an electronic device, considering that the wireless anti-theft system may mistakenly identify the electronic device as stolen and issue an alarm, the device status information corresponding to the electronic device can be obtained to identify scenarios where the possibility of the electronic device being stolen is low.

[0033] In some embodiments, the device status information may include at least one of radio frequency information, battery status information, positioning information, and posture information. Radio frequency information may be information corresponding to the radio frequency signal received by the electronic device, for example, it may include information such as the received signal strength, frequency, and phase; battery status information may include information such as whether the battery is in a charging state and the battery power; positioning information may include location information detected by the positioning module of the electronic device; posture information may include the position and posture information of the electronic device, and the posture information may be detected by the inertial measurement unit (IMU) of the electronic device. Of course, the device status information of the electronic device is not limited to this, and may also include other information, such as camera status information.

[0034] In a possible implementation, when the electronic device itself performs anti-theft detection and alarm, the electronic device can obtain the above device status information through the relevant interface in the system; when an external device performs anti-theft detection and alarm on the electronic device, the external device can obtain the above device status information from the electronic device. For example, the electronic device can broadcast the above device status information in real time so that the external device can receive the above device status information.

[0035] Step S120: if it is determined based on the device status information that the electronic device is in a target scenario, then limiting the output of anti-theft alarm information for the electronic device, the target scenario being a scenario where the probability of the electronic device being stolen is less than a target probability.

[0036] In the embodiment of the present application, after obtaining the above device status information, the scene in which the electronic device is currently located can be determined based on the device status information. According to the determined scene in which the electronic device is located, it can be determined whether the scene in which the electronic device is located is a target scene in which the probability of theft is less than the target probability, and the target probability can be 90%, 95%, 98%, etc., and the specific numerical value can be unlimited; if the electronic device is currently in the above target scene, it means that the electronic device is unlikely to be stolen, so in such a case, the output of anti-theft alarm information for the electronic device can be limited to avoid misidentifying the electronic device as stolen and alarming, thereby reducing the number of false alarms when the electronic device is anti-theft. In addition, if it is determined that the electronic device is not currently in the above target scene, then when performing anti-theft detection and alarm on the electronic device, normal processing can be performed, that is, when the electronic device is detected to meet the conditions for anti-theft alarm, the anti-theft alarm information is output.

[0037] Among them, the above target scenario can be a scenario where the probability of electronic device theft is less than the target probability determined based on prior information. Prior information refers to the experience and historical data that have been obtained before obtaining samples or conducting experiments. This information can be used in statistical inference and statistical decision-making because they provide important clues about future uncertainties. In the embodiment of the present application, the prior information can be information collected for electronic devices on display in stores, such as the scenarios in which electronic devices are stolen and the various scenarios in which electronic devices may be in stores.

[0038] In some embodiments, the above target scenarios may at least include: a scenario where the electronic device is in a charging state, a scenario where the electronic device is in a waterproof test, and a scenario where the electronic device is in an underwater photography test. It is understandable that when the electronic device is in a charging state, it is likely to be in a state where it is not moving when it is in a booth, and the probability of the electronic device being stolen is low in this scenario; when the electronic device is in a waterproof test scenario, the electronic device is usually in a drum washing machine, a pulsator washing machine, a small cleaning device, and the electronic device is also very likely not to have left the store; when the electronic device is in an underwater photography test scenario, the electronic device is taking photos underwater, and at this time the electronic device is also very likely not to have left the store, so when it is determined that the electronic device is in the above scenarios, the output of the anti-theft alarm information is limited, thereby reducing the number of times the anti-theft alarm information is output by mistake.

[0039] In some embodiments, when determining the scene in which the electronic device is located based on the device state information of the electronic device, a pre-trained scene recognition model may be used to determine the scene in which the electronic device is located according to the device state information. Specifically, the above device state information may be input into a pre-trained scene recognition model to obtain a result output by the scene recognition model, and the scene in which the electronic device is located may be obtained according to the result output by the scene recognition model.

[0040] In a possible implementation, the above scene recognition model may be pre-trained based on the device status information of each device in the store at a historical moment and the scene in which it is located. Each piece of collected device status information may be annotated with a corresponding scene label, which is used to characterize the scene at the historical moment corresponding to each device status information.

[0041] Optionally, the above scene recognition model can be trained in the following way: the device status information marked with the above scene labels can be obtained in advance to construct a sample data set; when the scene recognition model is trained based on the sample data set, the device status information can be input into the initial model to obtain the result of the initial model output, and the target loss value of the initial model can be determined according to the output result and the scene label corresponding to the device status information; after determining the target loss value corresponding to the initial model, the initial model can be iteratively trained according to the target loss value to obtain the final scene recognition model. Among them, the initial model can be a neural network, a Softmax logistic regression model, a support vector machine, etc., and the specific initial model can be not limited; when determining the target loss value, the loss value can be determined according to the difference between the output result and the marked scene label.

[0042] When the initial model is iteratively trained according to the target loss value, the model parameters of the initial model can be adjusted according to the calculated target loss value; the device status information is repeatedly input into the initial model to obtain the output result of the initial model, and the target loss value of the initial model can be determined according to the output result and the scene label, and the model parameters of the initial model can be adjusted according to the calculated target loss value until the training end condition is met to obtain the trained scene recognition model. The training end condition of iterative training may include: the number of iterative training reaches the target number; or the total loss value of the initial model meets the set condition.

[0043] In some implementations, when limiting the output of anti-theft alarm information for an electronic device, the number of times the anti-theft alarm information is output may be reduced, or the output of the anti-theft alarm information for the electronic device may be prohibited, that is, the anti-theft alarm information is not output. Among them, when reducing the number of times the anti-theft alarm information is output, the anti-theft alarm information may not be output in some cases even if the electronic device is detected to meet the anti-theft alarm conditions; and when prohibiting the output of the anti-theft alarm information for an electronic device, the anti-theft alarm information may not be output in any case even if the electronic device is detected to meet the anti-theft alarm conditions.

[0044] In a possible implementation, when limiting the output of anti-theft alarm information for an electronic device, it can be determined whether the positioning data of the electronic device drifts within a target time length when the electronic device meets the anti-theft alarm condition. The target time length can be 5 seconds, 10 seconds, 30 seconds, etc. The specific value of the target time length can be unlimited; if the positioning data of the electronic device does not drift within the target time length, the anti-theft alarm information can be not output; if the positioning data drifts within the target time length, it can be further determined whether the drift generated by the positioning data of the electronic device continues to be greater than the target threshold; if the drift generated by the positioning data of the electronic device continues to be greater than the target threshold, the filtering effect of the positioning data filtering algorithm can be increased. It can be understood that since it is usually necessary to determine whether the electronic device is stolen based on the positioning data of the electronic device, in a scenario where the possibility of the electronic device being stolen is small, it is usually due to inaccurate positioning that it is mistakenly identified as stolen. Therefore, the filtering effect of the filtering algorithm can be increased on the positioning data to better reduce noise and drift, thereby ensuring the accuracy of the positioning data and pulling the drift of the positioning data back to a normal value.

[0045] In some embodiments, after obtaining the device status information of the electronic device, the device status information can also be input into a pre-trained theft identification model to obtain the theft probability output by the theft identification model; if the theft probability output by the theft identification model is less than the target probability, the anti-theft alarm information for the electronic device can be limited to output; if the theft probability output by the theft identification model is greater than or equal to the target probability, normal processing can be performed when the anti-theft detection and alarm are performed on the electronic device, that is, the anti-theft alarm information is output when the electronic device is detected to meet the conditions for the anti-theft alarm. Among them, the theft identification model can be pre-trained based on the device status information of the electronic devices displayed in the store in different scenes, and each device status information can be annotated with the probability of theft in the scene corresponding to each device status information. In this way, it can also be realized to identify that the electronic device is in a scene where the probability of theft is less than the target probability, and limit the output of the anti-theft alarm information, thereby reducing the number of false alarms when the electronic device is anti-theft.

[0046] The device anti-theft method provided in the embodiment of the present application obtains device status information corresponding to the electronic device, and if it is determined based on the device status information that the electronic device is in a target scenario, the anti-theft alarm information output for the electronic device is limited, and the target scenario is a scenario where the probability of the electronic device being stolen is less than the target probability. Thus, when it is determined that the possibility of the electronic device being stolen is small, the number of times the anti-theft alarm information is output can be limited, thereby reducing the number of false alarms when the electronic device is protected from theft.

[0047] See also Figure 3 , Figure 3 A schematic diagram of a device anti-theft method provided by another embodiment of the present application is shown below. Figure 3 The process shown is described in detail, and the device anti-theft method may specifically include the following steps:

[0048] Step S210: Acquire device status information corresponding to the electronic device.

[0049] In the embodiment of the present application, step S210 can refer to the contents of the aforementioned embodiment and will not be described again here.

[0050] Step S220: Match the device status information with the target status condition.

[0051] In the embodiment of the present application, when determining the scene in which the electronic device is located, the acquired device state information of the electronic device may be matched with the target state condition, so as to determine whether the electronic device is in the target scene according to the matching result. The target state condition may be a condition determined according to the device state information when the electronic device is in the target scene.

[0052] In some embodiments, historical device status information of different devices displayed in a store when they are in a target scenario can be obtained; the historical device status information can be filtered, for example, after removing information that is significantly different from other device status information; the filtered historical device status information is then clustered, for example, by using a K-means clustering method; based on the results obtained after clustering, the device status information of the cluster center can be obtained as the above target state condition.

[0053] In some embodiments, the above target state conditions can be determined in advance based on prior information. Prior information can include: prior knowledge collected when the electronic device displayed in the store is in the target scene. For example, when the electronic device is in a scene where the booth is not moved, it is in a charging state in most cases, so the target state condition can be determined as the battery being in a charging state; for another example, when the electronic device is in a waterproof test scene, the electronic device is usually in a drum washing machine, a pulsator washing machine, a small cleaning device and other products, and there is a high probability that it has not left the store. At this time, the radio frequency signal usually received by the electronic device is abnormal, the positioning function fails, and the IMU data is out of range; when the electronic device is in an underwater photography test scene, the electronic device takes pictures underwater, and there is a high probability that it has not left the store, the number of times, the camera of the electronic device is in an enabled state, the radio frequency signal is abnormal, and the positioning function fails. Therefore, based on the above prior information, the target state condition for identifying the electronic device in the target scene can be determined.

[0054] Step S230: If the device state information matches the target state condition, it is determined that the electronic device is in the target scene.

[0055] In an embodiment of the present application, after the acquired device status information of the electronic device is matched with the target status condition, based on the matching result, if the matching result indicates that the device status information matches the target status condition, then it can be determined that the electronic device is in the target scene; if the matching result indicates that the device status information does not match the target status condition, then it can be determined that the electronic device is not in the target scene.

[0056] Step S240: if it is determined based on the device status information that the electronic device is in a target scenario, then limiting the output of anti-theft alarm information for the electronic device, the target scenario being a scenario where the probability of the electronic device being stolen is less than a target probability.

[0057] In the embodiment of the present application, step S240 can refer to the contents of other embodiments and will not be repeated here.

[0058] The device anti-theft method provided in the embodiment of the present application obtains device status information corresponding to the electronic device, and then matches the device status information with the target status condition. When it is determined that the device status information matches the target status condition, it is determined that the electronic device is in the target scene, and the output of the anti-theft alarm information for the electronic device is limited. Therefore, when it is determined that the possibility of the electronic device being stolen is small, the number of times the anti-theft alarm information is output can be limited, thereby reducing the number of false alarms when the electronic device is protected from theft.

[0059] See also Figure 4 , Figure 4 FIG. 1 is a flow chart showing a device anti-theft method provided by another embodiment of the present application. Figure 4 The process shown is described in detail, and the device anti-theft method may specifically include the following steps:

[0060] Step S310: Obtain device status information corresponding to the electronic device.

[0061] In the embodiment of the present application, step S310 can refer to the contents of the aforementioned embodiment and will not be described again here.

[0062] Step S320: Match the device status information with the target status condition in the current alarm mode.

[0063] In an embodiment of the present application, the anti-theft system for electronic devices may include multiple alarm modes, and the corresponding scenarios for outputting anti-theft alarm information are different in different alarm modes, and there may be alarm modes that do not need to limit the output of anti-theft alarm information. It can be understood that in order to adapt to the needs of different stores, different sites or individuals, different alarm modes can be set so that the output of anti-theft alarm information can be limited in the scenarios where the electronic device is in demand. For example, the scenario corresponding to alarm mode 1 that requires the output of anti-theft alarm information to be limited is the scenario where the electronic device is in a charging state; the scenario corresponding to alarm mode 2 that requires the output of anti-theft alarm information to be limited is the scenario where the electronic device is in a waterproof test; the scenario corresponding to alarm mode 3 that requires the output of anti-theft alarm information to be limited is the scenario where the electronic device is in an underwater photography test. Based on this, when determining whether the electronic device is in a target scene, the device status information of the electronic device obtained can be matched with the target state condition corresponding to the current alarm mode to determine whether it is in the target scene where the output of anti-theft alarm information needs to be limited in the current alarm mode. Among them, the above current alarm mode can be the current alarm mode.

[0064] In some embodiments, when executing the device anti-theft method provided in the embodiments of the present application, it can be determined whether the current alarm mode is a target alarm mode, which includes scenarios in which the output of anti-theft alarm information needs to be restricted; if the current alarm mode is the target alarm mode, it means that in the current alarm mode, it is necessary to restrict the output of anti-theft alarm information when the electronic device is in the corresponding scenario. Therefore, the device anti-theft method provided in the embodiments of the present application can be executed, that is, the device status information corresponding to the electronic device is obtained, as well as subsequent steps.

[0065] In some embodiments, each of the above alarm modes may include a scenario where the output of the anti-theft alarm information needs to be restricted. In this case, multiple alarm modes may be enabled at the same time, so that when the electronic device is in a scenario where the output of the anti-theft alarm information needs to be restricted corresponding to any alarm mode, the output of the anti-theft alarm information can be restricted.

[0066] In some embodiments, each of the above alarm modes may include multiple scenarios where the output of anti-theft alarm information needs to be restricted. For example, alarm mode 3 includes a scenario where the electronic device is in a charging state and a scenario where the electronic device is in a waterproof test. When the current alarm mode is alarm mode 3, the output of anti-theft alarm information may be restricted when it is determined that the electronic device is in a charging state or a waterproof test.

[0067] Step S330: If the device state information matches the target state condition, it is determined that the electronic device is in the target scene.

[0068] Step S340: if it is determined based on the device status information that the electronic device is in a target scenario, then limiting the output of anti-theft alarm information for the electronic device, the target scenario being a scenario where the probability of the electronic device being stolen is less than a target probability.

[0069] In the embodiment of the present application, step S330 and step S340 can refer to the contents of the aforementioned embodiment and will not be described again here.

[0070] The device anti-theft method provided in the embodiment of the present application obtains device status information corresponding to the electronic device, and when it is determined that the electronic device is in a target scenario based on the device status information, limits the output of anti-theft alarm information for the electronic device. Therefore, when it is determined that the possibility of the electronic device being stolen is small, the number of times the anti-theft alarm information is output can be limited, thereby reducing the number of false alarms when the electronic device is protected from theft. In addition, the device status information is matched with the target status condition corresponding to the current alarm mode to determine whether the electronic device is in a scenario where the output of the anti-theft alarm information needs to be limited in the current alarm mode. Therefore, different alarm modes can be set when the needs of different stores, different sites or individuals are different, so that the output of the anti-theft alarm information can be limited when the electronic device is in a required scenario.

[0071] See also Figure 5 , Figure 5 A schematic diagram of a device anti-theft method provided in another embodiment of the present application is shown below. Figure 5 The process shown is described in detail, and the device anti-theft method may specifically include the following steps:

[0072] Step S410: Obtain device status information corresponding to the electronic device.

[0073] In the embodiment of the present application, step S410 can refer to the contents of the aforementioned embodiment and will not be described again here.

[0074] Step S420: If it is determined based on the device status information that the electronic device is in a target scene, and the electronic device is in an abnormal state under the target scene, then the anti-theft alarm information output for the electronic device is restricted, and the target scene is a scene where the probability of the electronic device being stolen is less than the target probability.

[0075] In the embodiments of the present application, considering that in a scenario where the probability of the electronic device being stolen is lower than the target probability, the electronic device may still be stolen, it is also possible to determine whether the electronic device is in an abnormal state under the target scene when it is determined that the electronic device is in the target scene; when it is determined that the electronic device is in an abnormal state under the target scene, the output of anti-theft alarm information for the electronic device is restricted, that is, the output of anti-theft alarm information for the electronic device is restricted only when it is determined that the electronic device is in the target scene and is in an abnormal state under the target scene; in addition, when it is determined that the electronic device is not in an abnormal state under the target scene, normal processing can be performed, that is, the electronic device is not restricted from outputting anti-theft alarm information, and the anti-theft alarm information is output when it is detected that the electronic device meets the conditions for the anti-theft alarm.

[0076] In some embodiments, when determining whether an electronic device is in an abnormal state under a target scenario, it may be to obtain change information of the device state information of the electronic device; then match the change information with the abnormal state condition corresponding to the above target scenario; if the change information satisfies the abnormal state condition corresponding to the target scenario, it indicates that the electronic device is in an abnormal state under the target scenario, and therefore the output of the anti-theft alarm information for the electronic device may be restricted; if the change information does not satisfy the abnormal state condition corresponding to the target scenario, it indicates that the electronic device is not in an abnormal state under the target scenario, and therefore normal processing may be performed, that is, the electronic device is not restricted from outputting the anti-theft alarm information, and the anti-theft alarm information is output when the electronic device is detected to meet the anti-theft alarm condition. It can be understood that the extreme situation of theft occurring in different scenarios where the probability of theft is less than the target probability is different, and therefore different abnormal state conditions may be determined for different scenarios.

[0077] In a possible implementation, when the target scenario includes a scenario where the electronic device is in a charging state, when the user simulates this scenario, it is very likely that the abnormal state of using a power bank to charge the electronic device is met. Therefore, it is possible to determine whether the abnormal state condition is met based on the change in positioning information, the change in posture information, and the change in the received radio frequency signal in the environment. In this scenario, the abnormal state condition may include continuous changes in positioning information, continuous changes in posture information, and continuous changes in radio frequency information of the received radio frequency signal.

[0078] In a possible implementation, the target scenario includes a scenario where an electronic device is in an underwater photography test. When a user simulates this scenario, the following conditions must be met: placing the electronic device in water without attracting the attention of store personnel, and trying to disable existing positioning technology and shielding the radio frequency signal to make the radio frequency signal abnormal. Therefore, it is possible to determine whether the abnormal state condition is met based on the change in posture information and the change information of the received radio frequency signal in the environment. In this scenario, the abnormal state condition may include continuous changes in posture information and continuous changes in the radio frequency information of the received radio frequency signal.

[0079] In one possible implementation, the target scenario includes a scenario where an electronic device is in a waterproof test. The electronic device is usually located in a drum washing machine, a pulsator washing machine, a small cleaning device, and the like. When a user simulates this scenario, the following conditions must be met: placing the electronic device in water, and shaking the electronic device at high speed until the sensor exceeds the range, without attracting the attention of the store staff, and trying to make the existing positioning technology ineffective, and shaking the electronic device at high speed until the sensor exceeds the range. Therefore, it is possible to determine whether the abnormal state condition is met by the change information of the received RF signal in the environment. In this scenario, the abnormal state condition may include continuous changes in the RF information of the received RF signal.

[0080] Optionally, in the above scenarios, when determining whether the RF information of the RF signal continues to change, taking into account that there may be multiple signal transmitting devices that emit RF signals in the environment in which the electronic device is located, it is possible to determine whether the signal amplitude of the RF signal transmitted by each signal transmitting device continues to decrease for each RF signal received from the signal transmitting device; based on the determination result, it is possible to determine the proportion of the number of signal transmitting devices whose signal amplitude continues to decrease to the total number of signal transmitting devices; if the determined proportion is greater than a proportion threshold, for example, greater than 80%, greater than 90%, etc., then it can be determined that the RF information of the received RF signal continues to change.

[0081] Optionally, in the above scenarios, when determining whether the RF information of the RF signal continues to change, it is possible to determine whether the signal amplitude of the RF signal transmitted by each signal transmitting device continues to decrease, and determine the reduction degree of the signal amplitude of the RF signal, for each RF signal transmitted by the received signal transmitting device; based on the determination result, it can be determined that the number of signal transmitting devices whose signal amplitude continues to decrease accounts for a first proportion of the total number of signal transmitting devices, and the number of signal transmitting devices whose signal amplitude reduction degree is greater than the target amplitude accounts for a second proportion of the total number of signal transmitting devices; if the determined first proportion is greater than a first threshold value, for example, greater than 80%, greater than 90%, etc., and the second proportion is greater than a second threshold value, for example, greater than 60%, 80%, etc., then it can be determined that the RF information of the received RF signal continues to change.

[0082] The device anti-theft method provided in the embodiment of the present application can limit the number of times anti-theft alarm information is output when it is determined that the possibility of the electronic device being stolen is low, thereby reducing the number of false alarms when the electronic device is protected from theft; in addition, when it is determined that the electronic device is in a scenario where the probability of theft is low, it is further determined whether the electronic device is in an abnormal state in the scenario, and only when the electronic device is in an abnormal state is the number of times anti-theft alarm information is output limited, thereby ensuring the accuracy of anti-theft detection and alarm, and effectively preventing the electronic device from being stolen.

[0083] See also Figure 6 , Figure 6 A schematic diagram of a device anti-theft method provided by another embodiment of the present application is shown below. Figure 6 The process shown is described in detail, and the device anti-theft method may specifically include the following steps:

[0084] Step S510: Acquire device status information corresponding to the electronic device, where the device status information includes current radio frequency information of the received radio frequency signal.

[0085] In the embodiment of the present application, step S510 can refer to the contents of the aforementioned embodiment and will not be described again here.

[0086] Step S520: If it is determined based on the device status information that the electronic device is in a target scene, and the current radio frequency information matches the target radio frequency information, then limiting the output of the anti-theft alarm information for the electronic device, wherein the target radio frequency information is determined based on historical radio frequency information of historical radio frequency signals received when the electronic device was in a target environment in the past, and the target scene is a scene in which the probability of the electronic device being stolen is less than the target probability.

[0087] In the embodiment of the present application, considering that the electronic device may still be stolen in a scenario where the probability of the electronic device being stolen is less than the target probability, it is also possible that the electronic device is stolen. Therefore, when it is determined that the electronic device is in the target scene, the current RF information of the RF signal received by the electronic device can be determined in the device status information of the electronic device; the current RF information is matched with the target RF information, and the target RF information is determined based on the historical RF information of the historical RF signal received when the electronic device was historically in the target environment; according to the matching result, if the matching result indicates that the current RF information matches the target RF information, it means that the electronic device is still in the target environment, and therefore the output of the anti-theft alarm information for the electronic device can be restricted, that is, when it is determined that the electronic device is in the target scene and the above current RF information matches the target RF information, the output of the anti-theft alarm information for the electronic device is restricted; in addition, when it is determined that the above current RF information does not match the target RF information, normal processing can be performed, that is, the electronic device is not restricted from outputting the anti-theft alarm information, and the anti-theft alarm information is output when it is detected that the electronic device meets the conditions for the anti-theft alarm.

[0088] Among them, the above current radio frequency information includes the received signal strength, frequency, phase and other information of the currently received radio frequency signal; the above target environment can be the environment when the electronic device is located in a store that needs to be protected from theft. It can be understood that when the electronic device is located in the above target environment, the radio frequency information of the radio frequency signal it receives is usually relatively stable, so the radio frequency information of the radio frequency signal received historically can be statistically analyzed and the target radio frequency information used as a reference standard can be determined, that is, the radio frequency information in the environment can be learned to be used as a reference standard to determine whether the electronic device is in the above target environment.

[0089] In some implementations, when the electronic device is located in the above target environment, radio frequency information of radio frequency signals received by the electronic device may be acquired; based on the acquired radio frequency information, the above target radio frequency information may be statistically obtained.

[0090] In a possible implementation, when the electronic device is located in the above target environment and the electronic device is in a charging state, the radio frequency information of the radio frequency signal received by the electronic device can be obtained; and based on the obtained radio frequency information, the above target radio frequency information can be statistically obtained. It can be understood that when the electronic device is located in the above target environment and the electronic device is in a charging state, the electronic device is usually located in an immobile state on a booth. At this time, the radio frequency signal received by the electronic device is relatively stable and can more accurately reflect the information of the radio frequency signal emitted by the signal transmitting device in the target environment. Therefore, the above target radio frequency information can be determined by the radio frequency information of the radio frequency signal received in such a situation.

[0091] In a possible implementation, when the electronic device is located in the above target environment and the positioning information of the electronic device remains unchanged, the radio frequency information of the radio frequency signal received by the electronic device can be obtained; and based on the obtained radio frequency information, the above target radio frequency information can be statistically obtained. It can be understood that when the electronic device is located in the above target environment and the positioning information of the electronic device remains unchanged, the electronic device is usually in a non-moving state. At this time, the radio frequency signal received by the electronic device is relatively stable and can more accurately reflect the information of the radio frequency signal emitted by the signal transmitting device in the target environment. Therefore, the above target radio frequency information can be determined by the radio frequency information of the radio frequency signal received in such a situation.

[0092] The device anti-theft method provided in the embodiment of the present application can limit the number of times anti-theft alarm information is output when it is determined that the possibility of the electronic device being stolen is low, thereby reducing the number of false alarms when the electronic device is protected from theft; in addition, when it is determined that the electronic device is in a scenario where the probability of theft is low, it is further determined whether the current radio frequency information of the radio frequency signal received by the electronic device matches the target radio frequency information historically learned in the current environment, and only when the current radio frequency information matches the target radio frequency information, the number of times the anti-theft alarm information is output is limited, thereby ensuring the accuracy of anti-theft detection and alarm, and effectively preventing the electronic device from being stolen.

[0093] It should be noted that the device anti-theft methods provided in the above embodiments can be implemented in combination with each other. Figure 7 The device anti-theft method involved in the above-mentioned embodiment is introduced.

[0094] like Figure 7As shown, the alarm mode for the electronic device to prevent theft can be set according to the user's setting operation for the alarm mode; according to the current alarm mode, it can be determined whether the current alarm mode includes a scenario where the output of the anti-theft alarm information needs to be restricted; if the current alarm mode does not include a scenario where the output of the anti-theft alarm information needs to be restricted, then normal processing can be performed, that is, the anti-theft alarm information is output when it is detected that the electronic device meets the conditions for the anti-theft alarm; if the current alarm mode includes a scenario where the output of the anti-theft alarm information needs to be restricted, then it can be determined whether the device state information of the electronic device matches the target state condition; if the device state information does not match the target state condition, then normal processing can be performed, that is, the anti-theft alarm information is output when it is detected that the electronic device meets the conditions for the anti-theft alarm; if the device state information matches the target state condition, then it can be determined whether it is necessary to learn the environmental data in the environment where the electronic device is located, that is, learn the radio frequency information of the radio frequency signal received in the environment (the target radio frequency information in the aforementioned embodiment) according to the scenario corresponding to the target state condition and the current alarm mode; if it is necessary to learn the environmental data in the environment where the electronic device is located, then the environmental data in the environment where the electronic device is located can be learned, and the learned environmental data can be stored.

[0095] In addition, when the device status information matches the target status condition, it can be further determined whether the electronic device is in an abnormal state; if the electronic device is in an abnormal state, the output of the anti-theft alarm information can be limited. When limiting the output of the anti-theft alarm information, it can be determined whether the positioning drifts within the target time length; if the drift does not occur within the target time length, the anti-theft alarm information can be not output; if the drift occurs within the target time length, it can be further determined whether the drift generated by the positioning data of the electronic device continues to be greater than the target threshold; if the drift generated by the positioning data of the electronic device continues to be greater than the target threshold, then the filtering effect of the positioning data filtering algorithm can be increased to better reduce noise and drift, thereby ensuring the accuracy of the positioning data, and pulling the drift of the positioning data back to the normal value, so as to achieve the effect of not outputting the anti-theft alarm information; if the drift generated by the positioning data does not continue to be greater than the target threshold, the anti-theft alarm information can be output. Furthermore, if the electronic device is not in an abnormal state, it can be determined whether there is currently learned environmental data; if there is currently learned environmental data, the current radio frequency information of the radio frequency signal received by the electronic device can be matched with the environmental data; if the current radio frequency information matches the environmental data, anti-theft alarm information can be output; if there is currently no learned environmental data, the anti-theft alarm information can be directly output.

[0096] Different alarm modes are described below by giving examples. For example, the alarm modes may include alarm mode 1, alarm mode 2, alarm mode 3, alarm mode 4, alarm mode 5 and alarm mode 6. In alarm mode 1, the anti-theft alarm information may be output normally, that is, the anti-theft alarm information is output when it is detected that the electronic device meets the anti-theft alarm conditions; in alarm mode 2, the anti-theft alarm information may be output in a scenario where the electronic device is in a charging state, and the radio frequency information of the radio frequency signal in the environment may be learned when the electronic device is in a charging state, and the learned target radio frequency information may be stored; in alarm mode 3, the anti-theft alarm information may be output in a scenario where the electronic device is in a charging state, and when it is determined that the electronic device is in an abnormal state in the charging state, the anti-theft alarm information may be output; in alarm mode 4, the radio frequency signal in the environment may be learned when the electronic device is in a charging state. The RF information of the RF signal in the environment is learned when the device is in the charging state, and the learned target RF information is stored, and when the RF information of the received RF signal matches the stored target RF information, the output of the anti-theft alarm information is limited; in alarm mode 5, when the device is in the charging state, the RF information of the RF signal in the environment is learned, and the learned target RF information is stored, and as long as the RF information of the received RF signal matches the stored target RF information, the output of the anti-theft alarm information is limited; in alarm mode 6, the output of the anti-theft alarm information may be limited when the electronic device is in a waterproof test scenario or an underwater photography test scenario.

[0097] Through the above implementation methods, customized alarm modes can be supported, and relevant personnel can flexibly adjust according to on-site conditions or personal needs. For example, the alarm sensitivity can be increased when there are too many people and it is difficult to care, and the alarm sensitivity can be reduced when the user needs a quiet environment experience, so as to optimize the user experience.

[0098] See also Figure 8 , which shows a structural block diagram of a device anti-theft device 600 provided in an embodiment of the present application. The device anti-theft device 600 applies the above-mentioned electronic device, and the device anti-theft device 600 includes: a state acquisition module 610 and an alarm limitation module 620. Among them, the state acquisition module 610 is used to obtain device state information corresponding to the electronic device; the alarm limitation module 620 is used to limit the output of anti-theft alarm information for the electronic device if it is determined that the electronic device is in a target scene based on the device state information, and the target scene is a scene where the probability of the electronic device being stolen is less than the target probability.

[0099] In some implementations, the target scene includes at least a scene in which the electronic device is in a charging state, a scene in which the electronic device is in a waterproof test, and a scene in which the electronic device is in an underwater photography test.

[0100] In some embodiments, the device anti-theft device 600 may further include a state matching module and a scene determination module. The state matching module is used to match the device state information with a target state condition before limiting the output of the anti-theft alarm information for the electronic device if the electronic device is determined to be in a target scene based on the device state information; the scene determination module is used to determine that the electronic device is in a target scene if the device state information matches the target state condition.

[0101] In a possible implementation, the target scenario is a scenario in which the output of anti-theft alarm information needs to be restricted in the current alarm mode, and the state matching module can be specifically used to match the device state information with the target state condition in the current alarm mode.

[0102] In some implementations, the status acquisition module 610 may be specifically used to acquire device status information corresponding to the electronic device if the current alarm mode is a target alarm mode, wherein the target alarm mode includes a scenario where output of anti-theft alarm information needs to be restricted.

[0103] In some embodiments, the alarm limiting module 620 may be specifically used to limit the output of anti-theft alarm information for the electronic device if it is determined based on the device status information that the electronic device is in a target scene and the electronic device is in an abnormal state in the target scene.

[0104] In a possible implementation, the alarm limitation module 620 may be specifically used to: if it is determined based on the device status information that the electronic device is in a target scene, obtain change information of the device status information; if the change information satisfies the abnormal status condition corresponding to the target scene, limit the output of the anti-theft alarm information for the electronic device.

[0105] In some embodiments, the device status information includes current RF information of the received RF signal, and the alarm limitation module 620 can be specifically used to: if it is determined based on the device status information that the electronic device is in a target scene, and the current RF information matches the target RF information, then limit the output of the anti-theft alarm information for the electronic device, and the target RF information is determined based on historical RF information of historical RF signals received when the electronic device was historically in the target environment.

[0106] In some embodiments, the alarm limiting module 620 may be specifically used to reduce the number of times anti-theft alarm information is output for the electronic device, or prohibit outputting anti-theft alarm information for the electronic device if the electronic device is in the target scene based on the device status information.

[0110] In summary, the solution provided by the present application, by acquiring the device status information corresponding to the electronic device, if it is determined based on the device status information that the electronic device is in a target scenario, then the anti-theft alarm information output for the electronic device is limited, and the target scenario is a scenario where the probability of the electronic device being stolen is less than the target probability. Thus, when it is determined that the possibility of the electronic device being stolen is small, the number of times the anti-theft alarm information is output can be limited, thereby reducing the number of false alarms when the electronic device is protected from theft.
