Veriff’s deepfakes quiz shows the user 12 photos and videos, some real and some fake. How tough is it? Biometric Update took the test and guessed 10 out of 12 correctly, or 83 percent. But the average, says Veriff, is just 55 percent – reflecting a generally middling awareness of the threat in the U.S. According to the report, only 63 percent of U.S. adults say they are familiar with the term “deepfake,” compared with 74 percent in the UK and 67 percent in Brazil.
