TikTok parent company ByteDance has built a feature that could let users create their own deepfakes. The feature, referred to as Face Swap, was spotted in code in both TikTok and the Chinese app Douyin. It asks users to scan their face and then transfers their image to videos. On one hand, the feature could be seen as a natural evolution of other face swapping tech. On the other hand, it could have some very unpleasant repercussions.
