Black Lives Matter could change facial recognition forever -- if Big Tech doesn't stand in the way

That's why the announcements by IBM, Amazon and Microsoft were a success for activists -- a rare retreat by some of Silicon Valley's biggest names over a key new technology. This came from years of work by researchers including Joy Buolamwini to make the case that facial recognition software is biased. A test commissioned by the ACLU of Northern California found Amazon's software called Rekognition misidentified 28 lawmakers as people arrested in a crime. That happens in part because the systems are trained on data sets that are themselves skewed.
