The ethical questions that haunt facial-recognition research
In the study on Uyghur faces published by Wiley, the researchers didn’t gather photos from online, but said they took pictures of more than 300 Uyghur, Korean and Tibetan 18–22-year-old students at Dalian Minzu University in northeast China, where some of the scientists worked. Months after the study was published, the authors added a note to say that the students had consented to this. But the researchers’ assertions don’t assuage ethical concerns, says Yves Moreau, a computational biologist at the Catholic University of Leuven. He sent Wiley a request to retract the work last year, together with the Toronto-based advocacy group Tech Inquiry.
