專利摘要(英)
A verification method and a verification apparatus based on attacking image style transfer are provided. In the method, a style transfer is performed on a verification image for verifying an identity, so as to generate multiple stylized images having at least one style, in which the style transfer includes modifying a local pattern of the verification image while retaining a global pattern of the verification image; at least one of the verification image and the stylized images is processed to add interference signals with at least one type of specific pattern for interfering image recognition; and prompting the processed stylized images and receiving a selection operation on the stylized images to verify an identity of the object performing the selection operation.
