How to stop AI from recognizing your face in selfies

A number of AI researchers are pushing back and developing ways to make sure AIs can't learn from personal data. Two of the latest are being presented this week at ICLR, a leading AI conference. "I don't like people taking things from me that they're not supposed to have," says Emily Wenger at the University of Chicago, who developed one of the first tools to do this, called Fawkes, with her colleagues last summer: "I guess a lot of us had a similar idea at the same time." Actions like deleting data that companies have on you, or deliberating polluting data sets with fake examples, can make it harder for companies to train accurate machine-learning models. But these efforts typically require collective action, with hundreds or thousands of people participating, to make an impact.
