[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0031] See also Figure 1 and Figure 2 , the embodiment of the present application provides a detection method for an electronic device 100. The detection method includes:

[0032] S01: Acquire the wireless network of the wireless device 200;

[0033] S02: Acquire transmission characteristics of data transmitted by the wireless device 200 according to the wireless network;

[0034] S03: When the transmission feature matches the preset feature, it is determined that there is a shooting device 300 connected to the wireless device 200 in the space 101 where the electronic apparatus 100 is located.

[0035] See also Figure 2 and Figure 3 , the embodiment of the present application further provides an electronic device 100. The detection method of the embodiment of the present application can be implemented by the electronic device 100 of the embodiment of the present application. The electronic device 100 includes a processor 10. Step S01, step S02 and step S03 can all be implemented by the processor 10. That is to say, the processor 10 can be used to obtain the wireless network of the wireless device 200 and obtain the transmission characteristics of the data transmitted by the wireless device 200 according to the wireless network, and when the transmission characteristics match the preset characteristics, determine that there is a shooting device 300 connected to the wireless device 200 in the space 101 where the electronic device 100 is located.

[0036] In some embodiments, the electronic device 100 includes a mobile phone, a tablet computer, a laptop computer, a smart wearable device (such as smart glasses, a smart bracelet, a smart watch, a smart helmet), a camera (such as a SLR camera, a mirrorless camera), etc., without any limitation. In a specific embodiment of the present application, the electronic device 100 is a mobile phone. The space 101 where the electronic device 100 is located may be a room where the user holds the electronic device 100. The wireless device 200 is a device capable of transmitting wireless signals, such as a router and an electronic device integrated with a wireless transmitting device or a wireless transmitting module, such as a wireless camera, etc. The shooting device 300 may be a camera, such as a pinhole camera. In an embodiment of the present application, the shooting device 300 and the wireless device 200 may be integrated together, for example, the two are integrated together to form a wireless camera, which can realize both the shooting function and the wireless transmission function. For example, the wireless camera can shoot through the shooting device 300 and then send the captured images and videos to the device connected to the wireless camera by wireless transmission. It is understandable that in some embodiments, the wireless device 200 and the shooting device 300 can also be set separately, and the two can transmit data. The shooting device 300 sends the captured images and videos to the device connected to the wireless camera communication through the wireless device 200.

[0037] It is understandable that with the development of electronic technology, various types of voyeurism incidents are increasing, and criminals use various methods to spy on users' privacy, such as using wireless voyeur cameras to take photos of people and steal users' privacy.

[0038] The detection method and electronic device 100 of the embodiment of the present application obtain the transmission characteristics of the wireless network transmission data by acquiring the wireless network signal of the wireless device 200, and when it is determined that the transmission characteristics match the preset characteristics, it is determined that there is a shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located. In this way, by simply acquiring the transmission characteristics of the data transmitted by the wireless device 200, and then comparing it with the preset characteristics, it is possible to detect whether there is a shooting device 300 (such as a wireless camera) in the space 101 where the electronic device 100 is located, thereby reminding the user to protect the user's privacy. In addition, compared with the use of mobile phone cameras or infrared detection for detection. The detection method of the present application can effectively realize the detection of hidden cameras using mobile phones without increasing the cost of mobile phones.

[0039] It should be noted that, in the embodiments of the present application, the electronic device 100 can obtain the wireless network of the wireless device 200 and the transmission characteristics of the data transmitted by the wireless device 200, which can be understood as the electronic device 100 can search for the air interface signal of the wireless network in the environment and detect the characteristics of the air interface of the wireless network, and perform traffic characteristic analysis on the air interface packet transmitted on the channel of the wireless device 200 to obtain the transmission characteristics of the data transmitted by the wireless device 200. In other words, the electronic device 100 can obtain the transmission characteristics of the transmission data on the channel of the wireless device 200 without connecting to the wireless network, such as the size and regularity of the transmission, but cannot obtain the specific content of the transmission data without connecting to the wireless network.

[0040] See also Figure 4 In some embodiments, step S02 comprises the steps of:

[0041] S021: Obtaining the amount of data transmitted by the wireless network during each predetermined time period;

[0042] S022: Determine a transmission feature according to the arrangement of the transmission amount of data transmitted by the wireless network in a plurality of predetermined time periods.

[0043] Please refer to Figure 3 In some implementations, step S021 and step S022 may be implemented by the processor 10. That is, the processor 10 may be used to obtain the transmission amount of data transmitted by the wireless network in each predetermined time period and determine the transmission characteristics according to the transmission amount distribution of data transmitted by the wireless network in multiple predetermined time periods.

[0044] Specifically, in this embodiment, the transmission amount can be understood as the size of the transmission data within a predetermined time period, and the "predetermined time period" can be a time period or a unit time period preset by the electronic device 100. Taking the predetermined time period as a unit time period as an example, the processor 10 of the electronic device 100 can obtain the size of the transmission data on the channel of the wireless device 200 within each unit time period. For example, when performing video transmission, when the object is in a stationary state, the size of the transmission data per unit time is small, and when the object is in a moving state, the size of the transmission data per unit time is large. In this way, the electronic device 100 can determine the transmission characteristics of the wireless device 200 by analyzing the arrangement of the transmission amount of the transmission data in multiple unit times. Thereby, it is compared with the preset characteristics, and when the transmission characteristics match the preset characteristics, it is determined that there is a shooting device 300 connected to the wireless device 200, that is, a sneak shooting device, in the space where the electronic device 100 is located.

[0045] It can be understood that the "preset feature" can be understood as a feature that is pre-set by the electronic device 100 and has a certain regularity. For example, the preset feature can be a matching model established by the electronic device 100 with time as the horizontal axis and data size as the vertical axis. Each preset time period corresponds to a data size. When the transmission feature of the transmitted data completely matches the preset feature or the matching degree between the two is greater than a predetermined value, it is determined that the transmission feature of the transmitted data of the wireless device 200 matches the preset feature, thereby determining that the shooting device 300 exists in the space where the electronic device 100 is located, and then reminding the user to protect the user's privacy.

[0046] See also Figure 5 In some embodiments, step S02 comprises the steps of:

[0047] S023: When there is a moving object in the space where the electronic device 100 is located, the transmission characteristics of the data transmitted by the wireless device 200 are obtained.

[0048] Please refer to Figure 3 In some implementations, step S023 may be implemented by the processor 10. That is, the processor 10 may be used to obtain the transmission characteristics of the data transmitted by the wireless device 200 when there is a moving object in the space where the electronic device 100 is located.

[0049] Understandable, see Figure 6 , Figure 6 FIG. 3 is a schematic diagram of a scene showing transmission characteristics obtained by the shooting device 300 when shooting still pictures and moving pictures, wherein the horizontal axis represents time and the vertical axis represents the size of the transmitted data packet. Figure 6 It can be seen that if there is a shooting device 300 in the space 101 where the electronic device 100 is located, and there are no moving objects in the space 101 where the electronic device 100 is located, since the images shot by the shooting device 300 are all static images, the size of the transmitted data is small and relatively uniform, and the fluctuation is small. In this way, since there may be multiple wireless devices 200 in the space, there may also be other users connecting to the wireless device 200 for use, such as watching videos, etc. In this case, there is also data transmission, but since static images and data are all transmitted, the size of the transmitted data remains basically unchanged or fluctuates slightly, and it is impossible to determine whether there is a shooting device connected to the wireless device 200 in the space where the electronic device 100 is located.

[0050] In such a case, if there is a moving object in the space where the electronic device 100 is located, the picture captured by the shooting device 300 will have the object moving continuously, so that the data size of the captured video image will change, and the size of the transmitted data will fluctuate greatly. In such a case, the electronic device 100 obtains the transmission characteristics of the data transmitted by the wireless device 200, and can specifically exclude the wireless devices 200 that do not have large data size fluctuations. It only needs to specifically obtain the transmission characteristics of the wireless devices 200 with large fluctuations in data transmission volume, which is more efficient and can also exclude other wireless devices 200 in the space, thereby improving the detection efficiency.

[0051] For example, see Figure 7 In one example, the electronic device 100 obtains two wireless signals, which come from two wireless devices 200, including a first wireless device 201 and a second wireless device 202. The first wireless device 201 is connected to a shooting device 300 set in the room where the electronic device 100 is located or integrated in the shooting device 300, and the second wireless device 202 is set in the next room or in other places outside the room. The second wireless device 202 is connected to the electronic devices of other users, and there is traffic transmission, such as watching TV through electronic devices such as mobile phones. In this case, the size of the data transmitted by the second wireless device 202 is basically unchanged or has small fluctuations. At this time, if there are moving objects inside the space where the electronic device 100 is located, the shooting device 300 shoots a static video, and the data traffic transmitted by the first wireless device 201 is also relatively stable, and the fluctuation is also small. In this case, even if the electronic device 100 obtains the transmission characteristics of the two wireless devices 200, it cannot be determined which one is connected to the shooting device 300. However, if there are moving objects in the space where the electronic device 100 is located, the data flow rate transmitted on the first wireless device 201 will fluctuate greatly, while the second wireless device 202 will remain basically unchanged or fluctuate less. In this way, the first wireless device 201 can be excluded, and there is no need to obtain the transmission characteristics of the second wireless device 202. It is only necessary to obtain the transmission characteristics of the first wireless device 201 and then match and determine with the preset characteristics, thereby improving the detection efficiency.

[0052] See also Figure 8 In some embodiments, step S023 includes the steps of:

[0053] S0231: Acquire multiple transmission characteristics within a predetermined time period;

[0054] Wherein, each transmission feature is obtained when the object moves, and each transmission feature corresponds to a preset feature;

[0055] Step S03 includes the steps of:

[0056] S031: When each transmission feature matches the corresponding preset feature, it is determined that there is a shooting device 300 connected to the wireless device 200 in the space where the electronic apparatus 100 is located.

[0057] Please refer to Figure 3 In some embodiments, both step S0231 and step S031 can be implemented by the processor 10. That is, the processor 10 can be used to obtain multiple transmission features within a predetermined time period, wherein each transmission feature is obtained when the object moves, each transmission feature corresponds to a preset feature, and when each transmission feature matches the corresponding preset feature, it is determined that there is a shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located.

[0058] It can be understood that in this embodiment, only when multiple transmission features in each predetermined time period match the preset features, it is determined that there is a shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located. In this way, after multiple matching and comparison, the accuracy of detection can be improved.

[0059] In an example, see Figure 6 ,The object can make multiple moves within a predetermined time period, e.g. Figure 6 As shown, the user can make three movements, and each time the electronic device 100 moves, the transmission characteristics of a wireless device 200 are obtained, and the electronic device automatically generates a preset characteristic. In this case, only when the transmission characteristics obtained three times match the corresponding preset characteristics can it be determined that the wireless device 200 is connected to a shooting device 300 (i.e., a sneak camera device). During the detection process, the transmission characteristics obtained by each movement can be compared in sequence. For example, during the first movement, the transmission characteristics are obtained, and when the transmission characteristics match the preset characteristics, the second movement is performed, the transmission characteristics of the second movement are obtained and matched, and so on. If the transmission characteristics do not match the preset characteristics in one of the times, it means that there is no shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located, and the detection is terminated without the need to detect and match the next movement, thereby improving the detection efficiency.

[0060] See also Fig. 9 In certain embodiments, the detection method further comprises:

[0061] S04: Send a prompt message;

[0062] The prompt information is used to prompt the user to move an object in the space where the electronic device 100 is located.

[0063] Please refer to Figure 3In some implementations, step S04 may be implemented by the processor 10. That is, the processor 10 may be used to issue a prompt message to prompt the user to move an object in the space where the electronic device 100 is located.

[0064] In this way, the user can move the object in the space where the electronic device 100 is located, such as a room, according to the prompt information, so that the electronic device 100 can obtain the transmission characteristics of the wireless device 200 when the object moves to improve the detection efficiency.

[0065] It can be understood that moving an object in the space where the electronic device 100 is located may be caused by the user moving the object according to the prompt information or by other objects controlled by the user moving the object according to the prompt information.

[0066] Specifically, in such an embodiment, the processor 10 of the electronic device 100 can send a prompt message to the user through the display screen of the electronic device 100, for example, prompting the user to move a certain distance within a preset time, such as walking X steps within N seconds, and the processor 10 can randomly generate the values ​​of N and X. In this way, the electronic device 100 can actively remind the user to move so that there are moving objects in the space where the electronic device 100 is located, so that the electronic device 100 obtains the transmission characteristics of the wireless device 200 and detects whether the transmission characteristics of the wireless device 200 match the preset characteristics, thereby improving the detection efficiency.

[0067] For further information, see Fig.10 In such a manner, the detection method further comprises the steps of:

[0068] S05: Generate preset features according to the prompt information.

[0069] Please refer to Figure 3 In some implementations, step S05 may be implemented by the processor 10. That is, the processor 10 may be used to generate a preset feature according to the prompt information.

[0070] In this way, when a prompt message is sent to prompt the user to move an object in the space where the electronic device 100 is located, the processor 10 can generate a preset feature according to the prompt message, and the preset feature corresponds to the prompt message. In this way, when the user moves the object in the space where the electronic device 100 is located according to the prompt, if there is a shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located, the transmission feature obtained by the processor 10 also matches the prompt message, so that the transmission feature will match the preset feature, thereby determining that there is a shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located, that is, a sneak camera device.

[0071] Specifically, the preset feature is generated based on the prompt information, and the prompt information is randomly generated by the processor 10. That is to say, when the prompt information is generated, the processor 10 also generates the preset feature corresponding to the prompt information.

[0072] In addition, in such an embodiment, the electronic device 100 may send multiple prompt messages in sequence within a predetermined time period, for example Figure 6 As shown, three prompt messages may be issued in sequence, and each prompt message corresponds to a preset feature. For example, three prompt messages respectively prompt three movements. During the detection process, when moving according to the first prompt message, the electronic device 100 obtains a transmission feature of a wireless device 200. If the transmission feature matches the preset feature automatically generated by the electronic device 100 according to the first prompt message, the electronic device 100 issues a second prompt message, and then obtains the transmission feature of the wireless device 200 for the second time and matches it, and so on, until the transmission feature obtained for the third time also matches the preset feature automatically generated by the electronic device 100 according to the third prompt message, it is determined that there is a shooting device connected to the wireless device 200 in the space where the electronic device 100 is located. In this way, the detection accuracy is high. Of course, it can be understood that in other embodiments, the number of prompt messages may be less than 3 times, such as 2 times or 1 time, and of course, it may also be more than 3 times, and there is no specific limitation. The more the number of prompt messages, the higher the detection accuracy.

[0073] See also Fig.11 In some embodiments, the detection method further comprises the steps of:

[0074] S06: Determine whether the matching degree between the transmission feature and the preset feature is greater than or equal to a preset value;

[0075] S07: When the matching degree is greater than a preset value, determining that the transmission feature matches the preset feature.

[0076] Please refer to Figure 3 In some embodiments, both step S06 and step S07 can be implemented by the processor 10. That is, the processor 10 can be used to determine whether the matching degree between the transmission feature and the preset feature is greater than or equal to a preset value and determine that the transmission feature matches the preset feature when the matching degree is greater than the preset value.

[0077] In this way, the transmission feature is determined to match the preset feature only when the matching degree between the transmission feature and the preset feature is greater than or equal to a preset value. This can improve the accuracy of detection and prevent misjudgment due to minor fluctuations and changes in the transmission feature.

[0078] Specifically, the preset value is a value preset by the electronic device 100, such as 80%, 85%, 90% or 95%, etc. For example, taking the preset value as 80%, it is determined that the transmission characteristics of the wireless device 200 match the preset characteristics only when the matching degree is greater than or equal to 80%. In other words, when the matching degree between the transmission characteristics and the preset characteristics is less than 80%, the wireless device 200 can be excluded, that is, there is a high probability that there is no shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located.

[0079] See also Fig.12 In some embodiments, the detection method further comprises the steps of:

[0080] S08: Determine whether the wireless device is continuously transmitting data;

[0081] S09 : When the wireless device 200 does not continuously transmit data, it is determined that there is no photographing device 300 connected to the wireless device 200 in the space where the electronic apparatus 100 is located.

[0082] Please refer to Figure 3 In some embodiments, steps S08 and S09 may be implemented by the processor 10. That is, the processor 10 may be used to determine that there is no shooting device 300 connected to the wireless device 200 in the space where the electronic apparatus 100 is located when the wireless device 200 does not continuously transmit data.

[0083] In this way, wireless devices 200 that are not continuously transmitting data in the space where the electronic device 100 is located can be excluded, thereby improving detection efficiency. It can be understood that in this embodiment, when it is determined that the wireless device 200 is continuously transmitting data, step S03 is executed.

[0084] Specifically, see Fig.13 , in one example, Fig.13In the space 101 where the electronic device 100 is located, there is a shooting device 300 and a first wireless device 201 connected to the shooting device 300, and there is also a second wireless device 202 in the space 101 that is not connected to the shooting device 300. There is wireless data transmission between the first wireless device 201 and the electronic device of the sneak photographer, such as a computer, and there is no user access to the second wireless device 202, and there is no data transmission, or there is user access to the second wireless device 202, but the user only intermittently uses the electronic device connected to the second wireless device 202 or does not use the electronic device connected to the second wireless device 202. In this way, there is only intermittent data transmission or no data transmission for the second wireless device 202, that is, the second wireless device 202 does not continuously transmit data. In this case, the electronic device 100 can determine whether the two wireless devices 200 have continuous data transmission, thereby excluding the second wireless device 202 and improving the detection efficiency.

[0085] See also Fig.14 In certain embodiments, the detection method further comprises:

[0086] S10: Determine whether the signal strength of the wireless network is less than a predetermined strength;

[0087] S11: When the signal strength of the wireless network is less than a predetermined strength, it is determined that there is no photographing device 300 connected to the wireless device 200 in the space where the electronic apparatus 100 is located.

[0088] Please refer to Figure 3 In some embodiments, both step S10 and step S11 can be implemented by the processor 10. That is, the processor 10 can be used to determine whether the signal strength of the wireless network is less than a predetermined strength and, when the signal strength of the wireless network is less than the predetermined strength, determine that there is no shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located.

[0089] In this way, the signal strength of the wireless network can be detected first to exclude the wireless device 200 whose signal strength is less than the predetermined strength, and determine that there is no shooting device 300 connected to the wireless device 200 in the space where the electronic device 100 is located, thereby improving the detection efficiency. It can be understood that when there are multiple wireless devices 200 in the space where the electronic device 100 is located, the wireless network with low signal strength can be excluded by detecting the signal strength, thereby improving the detection efficiency.

[0090] Specifically, see Fig.15 ,exist Fig.15In the example, there are a first wireless device 201 and a second wireless device 202 in the environment. The first wireless device 201 is located in the space 101 where the electronic device 100 is located (i.e., in the room where the electronic device 100 is located), and the second wireless device 202 is located in a room far away from the electronic device 100. In this case, the electronic device 100 detects that the signal strength of the second wireless device 202 is low, and the signal strength of the first wireless device 201 is strong. At this time, it can be ruled out that there cannot be a shooting device connected to the second wireless device 202 in the room where the electronic device 100 is located.

[0091] It is understandable that in some embodiments, the above steps S08, S09 and S10 may exist together, that is, the electronic device 100 can detect the signal strength and whether it is continuously transmitting data, thereby excluding the wireless device 200 that does not meet the conditions, thereby improving the detection efficiency. For example, see Fig.16 ,exist Fig.16 In the figure, there are four wireless devices 200 in the environment, including a first wireless device 201, a second wireless device 202, a third wireless device 203 and a fourth wireless device 204. The first wireless device 201 is connected with a photographing device to form a wireless camera which is arranged in the room where the electronic device 100 is located. The second wireless device 202 is connected with other electronic devices which are not candid photographing devices such as a photographing device. There is no continuous data transmission on the third wireless device 203. The fourth wireless device 204 is far away from the electronic device 100, and the signal loudness received by the electronic device 100 is weak. In this case, the electronic device 100 is in wireless monitoring mode, and can simultaneously obtain the wireless networks of the first wireless device 201, the second wireless device 202, the third wireless device 203, and the fourth wireless device 204. Then, since the fourth wireless device 204 is far away from the electronic device 100, the signal strength is weak and less than the preset strength, so the fourth wireless device 204 can be excluded, that is, there is no shooting device 300 (sneak-shooting device) connected to the fourth wireless device 204 in the room where the electronic device 100 is located. Although the third wireless device 203 meets the signal strength requirement, there is no continuous transmission data on the third wireless device 203, so the third wireless device 203 can also be excluded. Subsequently, by respectively obtaining the transmission characteristics of the first wireless device 201 and the second wireless device 202, and comparing the transmission characteristics of the two with the preset characteristics, it can be determined that the transmission characteristics of the first wireless device 201 match the preset characteristics, thereby determining that the shooting device connected to the first wireless device 201 exists in the space where the electronic device 100 is located, such as a sneak-shooting camera. The establishment and comparison of the transmission characteristics and the preset characteristics are described in the above-mentioned embodiments. For details, please refer to the above and will not be repeated here.
