I Suspect That The Other Person’s AI Can Change Their Face And Make Them Press Their Noses.

According to experts, the "AI face-changing" process mainly includes several key steps such as face recognition and tracking, facial feature extraction, face transformation and fusion, background environment rendering, and image and audio synthesis.

Behind it,

The core includes three parts:

First, use deep learning algorithms to accurately identify face images in videos and extract key facial features such as eyes, nose, and mouth.

Secondly, these features are matched, replaced and fused with the target face image.

Finally, by rendering the background environment and adding synthesized sounds, a highly realistic fake face-changing video is generated.

The emergence of AI face-changing technology

As a result, what you see may not necessarily be true.

How should we prevent it?

Experts say

In fact, no matter how realistic AI artificial face replacement is,

There are still some ways to identify authenticity
Fang Yu, a member of the Digital Economy and Security Working Group of the Security Professional Committee of the China Computer Federation: We can ask the other party to wave their hands in front of their face during the video conversation to identify real-time forged videos, because it needs to process the video. Real-time generation and processing and AI face-changing.
During the process of waving, it will cause data interference on the face. During the process of waving, the face he forged would vibrate or flash, or experience some abnormalities.
The second is that in point-to-point communication, you can ask questions that only the other party knows to verify the authenticity of the other party.

Yu Nenghai, executive dean of the School of Cyberspace Security at the University of Science and Technology of China, reminded that you can ask the other person to press their nose or face to observe changes in their face.

He said in an interview that if it were a real person's nose, it would deform when pressed, but the AI-generated nose would not.
Same goes for the face. A real face will deform when pressed.
