Microsoft President Brad Smith says both the government and private companies have a role in guiding ethical uses of facial-recognition technology. DAVID PAUL MORRIS/BLOOMBERG/GETTY IMAGES OVER THE PAST year, Silicon Valley has been grappling with the way it handles our data, our elections, and our speech. Now it's got a new concern: our faces. In just the past few weeks, critics assailed Amazon for selling facial recognition technology to local police departments, and Facebook for how it gained consent from Europeans to identify people in their photos. Microsoft has endured its own share of criticism lately around the ethical uses of its technology, as employees protested a contract under which US Immigration and Customs Enforcement uses Microsoft’s cloud-computing service. Microsoft says that contract did not involve facial recognition. When it comes to facial analysis, a Microsoft service used by other companies has been shown to be far more accurate for white men than for women or people of color.via
