Summary:
- Camellia Chan, a researcher, has developed a new technique called X-Phy to detect deepfakes, which are fake videos that appear to show real people doing or saying things they did not actually do.
- Deepfakes can be used to spread misinformation and have become a growing concern, especially in the age of social media. X-Phy helps identify the subtle differences between real and fake videos.
