Description

Technical Field

[0001] The present invention belongs to the technical field of anti-eavesdropping, and in particular relates to an electronic device anti-eavesdropping method, device and storage medium based on automatic audio blocking. Background Art

[0002] With the widespread popularity of smartphones, microphones and speakers, as important components of mobile phones, are widely used for voice calls, voice input and other functions. However, these audio components may also become a way for eavesdropping, resulting in user privacy leakage. In the prior art, there are mainly the following solutions for mobile phone anti-eavesdropping: Software permission control: restrict the application's access to the microphone through the permission management provided by the operating system. For example, users can view and manage which applications have microphone permissions in the phone settings. If it is found that an unnecessary application has obtained permissions, the user needs to manually disable the permission or even uninstall the application. This pure software solution relies on manual settings and monitoring by the user, which is cumbersome to operate and not intuitive and intelligent enough for ordinary users.

[0003] Physical switch control: Add physical switches at the hardware level to manually control the connection and disconnection of circuits of components such as microphones. For example, some technologies connect a push-button or sliding switch in series in the microphone circuit of a mobile phone, so that users can manually connect the microphone power when they need to use it and disconnect it when they don't. This method extends the usability of the microphone to the physical level, fundamentally preventing unauthorized use, but its disadvantage is that it is completely dependent on manual operation by the user, which is not convenient to use and cannot be automatically switched according to the usage scenario.

[0004] External interference device: By connecting an external device to the audio interface of the mobile phone (such as the microphone jack or data interface), an interference signal or a fake audio signal (such as white noise or a mute signal) is sent to the microphone circuit of the mobile phone, making the built-in microphone of the mobile phone ineffective, thereby blocking eavesdropping. For example, after some anti-eavesdropping devices are inserted into the headphone jack of the mobile phone, they will continuously output interference levels, making it impossible for the mobile phone to record the real environment sound. This method is effective when privacy needs to be protected, but because the device usually outputs interference all the time, when the user really needs to use the microphone for normal calls or recordings, the interference device must be manually removed or turned off. This means that users need to intervene manually, lack intelligent judgment, and have a poor user experience.

[0005] In summary, the above existing solutions either require users to perform complex permission settings or require additional manual operations (physical switches or plugging and unplugging devices). They are not highly intelligent and cannot automatically adjust the working status of the microphone according to the user's current actual needs. Therefore, there is an urgent need for an automated solution that can effectively prevent eavesdropping without requiring frequent user intervention. Summary of the invention

[0006] The purpose of the present invention is to provide an electronic device anti-eavesdropping method, device and storage medium based on automatic audio blocking, which can automatically identify whether the user intends to use the microphone, and automatically control the opening and closing of the microphone according to the identification result, thereby ensuring that the user can use the mobile phone functions normally while effectively preventing unauthorized eavesdropping, solving the shortcomings of the prior art of cumbersome manual operation and lack of automated control, and improving user experience and privacy security.

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides an electronic device anti-eavesdropping method based on automatic audio blocking, including: Establishing a control signal communication environment with an audio module of an electronic device, wherein the control signal communication environment includes taking over control of the audio module of the electronic device; Acquire multi-source real-time usage data of electronic devices; Acquiring the real-time usage status of the electronic device according to the multi-source real-time usage data; Determining the user's operation intention according to the real-time usage status; The audio module of the electronic device is controlled accordingly according to the user's operation intention; wherein the control includes releasing the control right of the audio module and restoring the control right of the audio module.

[0025] This embodiment establishes a control connection with the audio channel of the electronic device, and then automatically identifies whether the user intends to use the audio module according to the real-time usage status of the electronic device, and then automatically switches the control status of the audio module. While ensuring that the user can use the mobile phone functions normally, it effectively prevents unauthorized eavesdropping. In addition, the user does not need to manually enable or disable any hardware switches, and the audio module can be automatically turned on for normal use when needed, and automatically turned off afterwards, which greatly improves the anti-eavesdropping security and user experience.

[0026] Example 2

[0027] Based on Example 1, this example also makes the following design.

[0028] In this embodiment, a mobile phone is used as an electronic device that needs to be protected from eavesdropping, and the electronic device anti-eavesdropping method based on automatic audio blocking is divided into the following steps:

[0029] 1. Initial stage: When a communication connection is established with the mobile phone, the protection state is entered by default. At this time, the control of the mobile phone audio module is taken over, the microphone of the mobile phone is turned off or physically blocked, and the speaker does not make any sound. That is, the audio module circuit is logically connected, the mobile phone audio interface is occupied and the collection of ambient sound is blocked, preventing any application from recording unauthorized sound without the user's knowledge. When the user uses the mobile phone in this state, there will be no obvious changes, but the mobile phone is already in privacy protection mode.

[0030] 2. User intention detection phase: The detection module continuously monitors the usage status of the phone. When it captures features related to voice operation, it enters the user intention judgment process, including the following common scenarios:

[0031] Voice call scenario: When the user initiates or answers a voice call, the phone starts to use the speaker and microphone. When the phone speaker is detected to be activated (for example, the phone enters the call mode when the outgoing call beeps or the incoming call rings), it can be judged that the user may want to enter the voice call mode. Once it is confirmed that the phone is in the call mode today, the control of the microphone and speaker is immediately released, that is, the control of the microphone and speaker is released, allowing the phone to use its original microphone and speaker again to ensure that the call process proceeds normally. The entire switching process is fast and automatic, and the user can talk as usual without being affected. During the call, the phone audio function is not interfered with, and only the call is monitored in the background to see if it ends. When the call ends (judged by the call status or the speaker stops outputting), the control of the microphone and speaker is immediately taken back, and the system is restored to the initial protection state to continue anti-eavesdropping.

[0032] Voice input scenario: When a user performs voice input or recording operations on a mobile phone (for example, using a voice assistant or voice recognition to input text, or recording a voice message), the screen will often light up and call up the relevant application interface. At this time, the mobile phone screen is detected to change from off to on. If the user is detected to click the voice input button at the same time, it is determined that the user is preparing to perform voice input.

[0033] At this time, release the control of the microphone and speaker, let the phone microphone resume working, and allow the user to smoothly input voice. During the entire voice input process, continuously monitor the screen status and application request status; once it detects that the user has completed voice input (releases the voice input button) and turns off related functions (for example, the screen turns off), immediately take over the control of the microphone and speaker, turn off or shield the microphone again, and return to the protection state to prevent possible subsequent secret recording.

[0034] Other scenarios: For other scenarios that may involve the use of microphones, a comprehensive judgment can be made by combining multiple sensor signals. For example, when the phone is quickly raised, the whole device is close to the ear, and the screen is lit, it may indicate that the user is using the phone function; when the phone is quickly raised, the microphone is close to the mouth, and the screen is lit, it may indicate that the user is using the voice input function; when a specific voice wake-up word is detected and recognized (this situation needs to be coordinated with the mobile phone application), it may indicate that the user is calling the voice assistant.

[0035] In this embodiment, several trigger conditions can be pre-set. When the working state of the mobile phone meets any of the trigger conditions, it is considered that the user intends to use the microphone, thereby releasing the control of the microphone and making the microphone function of the mobile phone available. Similarly, after these uses are completed, the control of the microphone is immediately restored. By being compatible with multiple usage scenarios, this method can intelligently adapt to the user's daily operations.

[0036] 3. Continuous monitoring and recovery: During the entire period when the microphone is turned on for user use, the monitoring of the phone's working status and the judgment of the user's intention will not stop. The relevant status of the phone's operation is continuously detected to prevent the user from changing his mind or interrupting the operation. As long as it is detected that the user no longer needs the microphone (whether the call is hung up, the recording is stopped, or the user cancels the operation, etc.), the microphone is immediately turned off or blocked and the security protection mode is re-entered. This instant recovery mechanism ensures the security of the microphone when it is idle, and avoids the risk of the microphone being open for a long time due to user negligence. The entire process is seamless and transparent to the user, ensuring privacy and security without affecting the normal use of the phone's functions.

[0037] Example 3

[0038] like Figure 2As shown, this embodiment provides an electronic device anti-eavesdropping device based on automatic audio blocking, including a connection module, a control module and a detection module, and the functions of each module are as follows:

[0039] 1. Connection module: used to establish a connection with the audio channel of the mobile phone and transmit the necessary audio and on / off control signals. The connection method can be a wired interface (such as Type-C interface, audio jack) or a wireless interface (such as Bluetooth, etc.). After the device establishes a physical connection with the mobile phone through the interface, the anti-eavesdropping device can access the microphone and speaker circuits of the mobile phone through the connection module, obtain control authority for the microphone and speaker, and take over or release control of them. In other words, the connection module ensures that the device can physically or logically intervene in the audio path of the mobile phone, block the microphone input or speaker output when necessary, and restore the original audio function of the mobile phone when appropriate.

[0040] 2. Detection module: It is set inside the device and electrically connected to the control module to provide a detection signal, which is used to monitor the usage status of the mobile phone in real time to determine whether the user intends to turn on the microphone. This module integrates or connects multiple sensors and signal detection units to capture the user's operating behavior and environmental status from different aspects, and comprehensively determine whether the user currently needs to use the microphone. In this embodiment, the anti-eavesdropping device can also use the existing sensor information of the mobile phone, without the need to add expensive new sensors. Specifically, the detection module may include but is not limited to the following detection units:

[0041] Speaker usage detection unit: Infers the voice call scenario by monitoring the working status of the phone speaker. When the phone speaker starts to enter the call mode or emits a call ringtone, it can be determined that the user is or is about to make a voice call. This signal trigger means that the user is likely to enable the microphone to speak.

[0042] Screen status detection unit: Assists in judging user operation needs by monitoring the on and off status of the mobile phone screen. Usually, when users are performing voice input or making calls, they will light up the screen to perform operations (such as dialing or viewing the input interface), and may turn off the screen after finishing use. If the screen is detected to be lit and combined with other signs, the accuracy of judging user intentions can be improved. For example, if the screen suddenly lights up and the speaker moves immediately afterwards, it can be basically determined that it is a scene of making or receiving a call.

[0043] Other sensor detection units: Additional sensors including accelerometers, distance sensors, touch sensors, etc., are used to further verify the user's operation intention. For example, the accelerometer can determine whether the phone is picked up and placed next to the ear (a typical call action), the distance sensor can detect the ear approaching, and the touch sensor can detect specific interactive gestures. These sensor information combined with the above detection units can form a more comprehensive user intention recognition mechanism.

[0044] The detection module improves the accuracy of judging the user's true intention through the combination of the above-mentioned methods. When the comprehensive results of any detection unit or multiple units indicate that the user needs to use the microphone, a signal will be sent to the control module to trigger the microphone to turn on; conversely, when all relevant signs indicate that the user has no voice operation needs, the microphone is maintained or restored to the off state.

[0045] 3. Control module: The core control unit of the anti-eavesdropping device is set inside the device and connected to the connection module to control the connection and disconnection of the audio channel. It is used to intelligently judge the user's operation needs according to the signal provided by the detection module, and control the opening and closing of the microphone accordingly. The control module can be implemented by a logic circuit or a processor, and the corresponding software or firmware algorithm runs inside. Its working strategy includes: by default, the microphone is turned off or blocked (to prevent any unauthorized sound collection); when the information from the detection module indicates that the user intends to use the microphone, the control module immediately switches the state and turns on the microphone to allow normal voice calls or voice input; while the microphone is turned on for user use, the control module continuously monitors the feedback of the detection module. Once it is found that the user no longer needs to use the microphone (for example, the call ends or the voice input is completed), the microphone is quickly turned off or blocked again and restored to the default security state. Through the above intelligent control strategy, the state of the microphone can be dynamically adjusted according to user needs without manual intervention by the user.

[0046] Brief description of the working principle of the anti-eavesdropping device: After the device of the present invention is connected to a mobile phone, it immediately takes over the audio channel of the mobile phone in the initial state, so that the microphone of the mobile phone is disconnected or equivalently muted, and the speaker is also set to silent, so as to prevent the collection or leakage of sound information without the user's authorization. The device continuously monitors various state changes of the mobile phone through the detection module: when it is detected that the user intends to make a voice call or voice input, the control module immediately instructs the connection module to release the control of the microphone and speaker of the mobile phone, allowing the mobile phone to resume normal audio functions. In this way, the user can smoothly make calls or record operations without additional operations. Once the detection module determines that the voice call is over or the voice input is completed, the control module promptly instructs the connection module to take over the microphone and speaker again, switching them back to the safe shielding state to prevent possible passive recording or eavesdropping in the future. The whole process is completed automatically without the need for the user to manually switch the switch, ensuring a balance between security and convenience.
