Abstract: A camera identification method comprises identifying a to-be-identified camera using a light sensitivity deviation of each pixel in the to-be-identified camera; generating corresponding identification data; identifying a target camera using a light sensitivity deviation of each pixel in the target camera; and identifying the target camera by comparing a similarity between data that identifies the target camera and identification data of a known camera.

Abstract: A radar authentication method includes after obtaining output data of a to-be-authenticated radar, a computer device that first invokes a prediction model to obtain predicted data of the to-be-authenticated radar based on the output data of the to-be-authenticated radar, where the prediction model is obtained through training based on output data of a target radar. Then the computer device verifies, based on the predicted data of the to-be-authenticated radar and the output data of the to-be-authenticated radar, whether the to-be-authenticated radar and the target radar are the same radar.
