Popular Chinese short video app Douyin, known as TikTok outside China, has introduced a reverse-image search tool that enables some users to find in-video products such as clothing, which they can then purchase directly within the app.

The move could help Douyin’s owner ByteDance capitalise on the growing popularity of the video app, which had accumulated 320 million daily active users as of July. The privately held Beijing-based company just revised its revenue target for 2019 to 120 billion yuan (US$16.8 billion) from an earlier goal set late last year of 100 billion yuan, according to Reuters.

The new function was spotted by China tech analyst Matthew Brennan, who first showed the in-video search tool on Twitter last week. While watching a video clip of Chinese comedian Xiao Shenyang, more videos of the celebrity popped up after clicking a circle icon on the right side of the screen. As Brennan moved the search area over Xiao’s pants, similar clothing products popped up and could be bought directly by users.

ByteDance did not respond to a request for comment on Thursday but the description on the app’s page said the reverse search function can be used to find other videos of celebrities, or videos of similar-looking pets, based on still images – suggesting that the company is collecting identifiable data from its content that could potentially be used for generating ad revenue.

The function is only available to selected users on the Chinese version of the app and it is not clear whether Douyin will make it available to the overseas market in the future. It is also unclear whether the platform is scanning videos that Douyin users have tagged as private.

Twitter user @AlvinGrissomII commented under Brennan’s Twitter post, “This was predictable, but it still has horrifying implications for privacy”.
