The images were not taken by a person, but by development versions of iRobot’s Roomba robot vacuum, a company now owned by Amazon. They were then sent to Scale AI, a startup that contracts workers around the world to label data used to train artificial intelligence.

In 2022, MIT Technology Review obtained 15 screenshots of these private photos, which had been posted to closed social media groups. The images speak to the growing practice of sharing potentially sensitive data to train algorithms. They also reveal a whole data supply chain—and new points where personal information could leak out—that few consumers are even aware of. Read the full story.
