Deepfakes are videos that have been digitally manipulated (操纵) to show people saying words that they haven't (actual) spoken. In the past, videos like these could be made only by (train) special effects artists or video editors. Now, anyone with the right tools can make a convincing deepfake.
These videos are easy to make and (danger). Many people are worried
that deepfake technology will be misused. Imagine if someone made a deepfake of a(n) (politics) or another powerful person and then uploaded it to the Internet, how would people know whether what they were seeing and hearing was real?
Wael Abd-Almageed, who leads a team five other researchers at the
University of Southern California, is trying to answer that question. Wael Abd-Almageed and his team have designed computer software can determine whether a video is a deepfake." If there is inconsistency in the video, such as how the eyes move, we can spot it," he said.
How can you avoid being fooled by a deepfake? Wael Abd- Almageed suggests not immediately (believe) what you see online. Instead, (make) sure you research a video first. "Don't take anything on the Internet for granted," he warns. "Ask (you), 'Would this person really say something like this?'"
Wael Abd- Almageed also advises watching a video at slower speed so you can spot inconsistencies. This is possible by using the settings on most popular video platforms.
