1. An artificial intelligence-based identity verification method, performed by a verification device, the method comprising:
obtaining a to-be-verified face image inputted into the verification device;
performing at least one convolution operation on the face image, to obtain an image convolution feature of the face image;
performing non-linear mapping on the image convolution feature, to obtain a first pattern noise feature;
performing artificial intelligence-based device tracing processing on the face image, to obtain a photographing device identifier corresponding to a photographing device of the face image based on the first pattern noise feature extracted from the face image;
obtaining a verification device identifier corresponding to the verification device based on a second pattern noise feature corresponding to the verification device;
determining a similarity between the first pattern noise feature and the second pattern noise feature;
performing feature comparison on the photographing device identifier and the verification device identifier to obtain a comparison result according to the similarity; and
performing identity verification based on the face image in response to the comparison result indicating that the photographing device and the verification device are a same device.
