A Chinese app that lets users convincingly swap their faces with film or TV characters has rapidly become one of the country’s most downloaded apps, triggering a privacy row. Released on Friday, the Zao app went viral as Chinese users seized on the chance to see themselves act out scenes from well-known movies using deepfake technology, which has already prompted concerns elsewhere over potential misuse.
Users provide a series of selfies [in which they blink, move their mouths and make facial expressions], which the app uses to realistically morph the person’s animated likeness on to movies, TV shows or other content. The company was forced to issue a statement on Sunday pledging changes after critics attacked the app’s privacy policy, which it had “free, irrevocable, permanent, transferable, and relicenseable” rights to all user-generated content.
There has been growing concern over deepfakes, which use artificial intelligence to appear genuine. Critics say the technology can be used to create bogus videos to manipulate elections, defame someone, or potentially cause unrest by spreading misinformation on a massive scale.
