More Information
Summary:The invention discloses an image model hidden backdoor detection method and system, a storage medium and a terminal.Compared with the prior art, each training sample image is converted into a frequency spectrum image, target detection is conducted on the frequency spectrum image, and a target image is obtained; the method comprises the following steps: extracting a target image from a frequency spectrum image corresponding to the target image and taking the target image as to-be-determined frequency spectrum image fragments, respectively counting the number of each same to-be-determined frequency spectrum image fragment, and determining a trigger pattern embedded in the frequency spectrum image according to the number of each same to-be-determined frequency spectrum image fragment; and finally, based on the trigger pattern, determining a frequency spectrum image where the trigger pattern is located so as to complete detection of the back door sample image with the trigger pattern, thereby solving the problem
