Abstract

The invention provides an active defense method for image protection. The method comprises the following steps: receiving a real image; adding hidden information to the received real image to generate a first image; generating a semantic pattern in a specified area of the first image based on the hidden information so as to generate a second image; and adjusting the hidden information to make the semantic pattern similar to a predefined semantic pattern and make the second image similar to the real image. The invention further discloses a corresponding active defense device for image protection.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to active defense for image protection. Background technique [0002] Deep Fake (DeepFake) is a human body image synthesis technology based on artificial intelligence. Through network models such as automatic encoders and generative confrontation networks in deep learning, the generation, editing and replacement of human faces are realized. For example, let the target face follow the movements and expressions that imitate the original face; or replace the face in the original video with the target video; there are also many ways to introduce multi-modality such as audio, so that the speaker's lip shape and audio are consistent. match. In addition, the DeepFake video produced by the above-mentioned multiple generation methods can guarantee a high degree of visual naturalness. [0003] The current protection methods against DeepFake tampering images mainly include...
