Problems solved by technology
With the popularization of smart phones, more and more apps ask for higher recording and camera permissions. The traditional closing of apps can no longer reliably and effectively prevent the work of microphones and cameras.
[0003] Some apps obtain advanced permissions to monitor, such as giving the app recording permission. Once allowed, the app will always monitor the phone, or when there is a virus in the phone, some advanced viruses can directly obtain the highest permission of the phone, without the user's consent to monitor the phone, the user's information Safety cannot be guaranteed, there are certain defects

Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] The terminology used in the present invention is for the purpose of describing particular embodiments only and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise.
[0024] Such as figure 1 Shown, show a kind of hardware circuit design of the present invention to realize the method for anti-eavesdropping, video recording, comprise the steps:
[0025] S100. Manual adjustment: press or toggle the physical buttons / switches on the smart phone as needed;
[0026] S200. Signal path control: sending a control signal to the analog switch to control the state of the...

The invention provides a method for realizing anti-eavesdropping and video recording through hardware circuit design, which comprises the following steps of: pressing or shifting an entity key / switch on an intelligent machine according to requirements, sending a control signal to an analog switch, controlling the state of the input end of the analog switch, and finally, controlling the state of the input end of the analog switch according to the state of the input end of the analog switch. And switching on / off the camera and the microphone so as to switch between a normal mode and a safe mode. The intelligent machine is reasonable in structural design, a control signal is sent out by pressing an entity key or a toggle switch, the camera and the microphone are powered on and off through an analog switch, and the camera and the microphone cannot work after being powered off, so that the situation that an App of the intelligent machine stealthily monitors a user or shoots a video is avoided, the App cannot be recovered through software operation, and the intelligent machine is convenient to use. And leakage of user information is avoided.
Description
technical field [0001] The invention relates to the field of information security, in particular to a hardware circuit design method for realizing anti-eavesdropping and video recording. Background technique [0002] A smart phone, like a personal computer, has an independent operating system and an independent operating space. Users can install software, games, navigation and other programs provided by third-party service providers by themselves, and can realize wireless network communication through mobile communication networks. The general term for the type of mobile phone connected. The current development trend of smartphones is to fully incorporate a number of patented technologies such as artificial intelligence and 5G, making smartphones the most widely used patented products. With the popularization of smart phones, more and more apps ask for higher recording and camera permissions. The traditional closing of apps can no longer reliably and effectively prevent the...
