A face-swapping app that went viral on Chinese social media over the weekend sparked a privacy controversy within hours of its debut.

Just take a selfie and choose footage from a classic film or soap opera on the app, and a user can superimpose his or her face on any actor playing any role they like.

But after generating huge interest in its first two days of circulation, users soon learned that the pictures of their faces were no longer under their control.

The ZAO app – introduced by Momo, a social media app developer – uses “deepfake”, a technique for human image synthesis based on artificial intelligence.

Since its debut on Friday, hashtags with the name ZAO have had more than 8 million views on Weibo, China’s equivalent of Twitter. It had meanwhile zoomed to No 1 on the free entertainment app list in the Apple App Store as of Sunday.

However, almost immediately after it was released, users, lawyers and industry insiders began to question a clause in the app’s user agreement.
