Problems solved by technology
However, most cameras are purchased from a third party, and it is difficult to pre-program, so the key is easily leaked during distribution, and the camera does not have a key storage function, which makes it easier to leak the key, thereby reducing the security of the camera authentication process

Embodiment Construction
[0044] For terminals that require automatic control, such as self-driving vehicles, security facilities, Internet of Things (IoT) systems, etc., it is necessary to cooperate with the camera and the control system to achieve precise automatic control. Taking self-driving vehicles as an example, it is necessary to set up cameras at designated parts of the vehicle to capture corresponding images, such as setting up multiple cameras at the front, rear, sides of the vehicle, and inside the vehicle, and deploying on-board systems (control system), the vehicle-mounted system analyzes the video stream uploaded by the above-mentioned camera to judge the vehicle’s own vehicle condition and the surrounding environment of the vehicle, so as to control the various components of the vehicle (steering wheel, headlights, horn, windows, brakes, accelerator, etc.) , alarm, etc.) to achieve the effect of automatic driving.
[0045] Obviously, the video stream uploaded by the terminal's camera is...

Embodiments of the present application provide a camera identification method, authentication method, system, and terminal, which can use the sensitivity deviation of each pixel in the camera to be identified to identify the camera to be identified and generate corresponding identification data. The target camera can also be identified by using the photosensitive deviation of each pixel in the target camera, and the target camera can be authenticated by comparing the similarity between the data used to identify the target camera and the identification data of known cameras. It can be seen that this application does not need to improve the camera, and only needs to use the physical characteristics of the camera itself to identify and authenticate the camera. The data basis for identification and authentication will not be lost, and there is no need to store it. Therefore, the process of identification and authentication is safe. higher.
Description
technical field [0001] The present invention mainly relates to the technical field of image data processing, in particular to a camera identification method, authentication method, system and terminal. Background technique [0002] With people's requirements for simplified operations of various terminals, such as vehicles, more and more terminals use automatic control to liberate people's operations. In order to replace human operations, it is necessary to install a camera to replace the human eye and a control system to replace the human brain on the terminal. In this way, the combination of the camera and the control system can replace human beings to make decisions and control. The camera needs to be authenticated when it is used to ensure the legitimacy of the camera and avoid security risks brought by the operation of the control system such as the camera being maliciously replaced. [0003] Usually, the camera can be authenticated based on digital certificates and dig...
