Can disguises fool surveillance technology? (BBC)
putting a scarf over the mouth and nose, or simply wearing dark glasses could fool the system. However, this is beginning to change, says Shengcai Liao, an assistant professor at the Center for Biometrics and Security Research in Beijing, China. He says new techniques are being developed that can use information from the nose or mouth alone if the eyes are occluded, or from the eyes and eyebrows if a scarf is covering the lower part of the face. “It’s not possible to recognize a fully occluded face, but we can currently recognize faces with 30% or even 50% occlusion,” he said. “We have even had success performing recognition from a mouth alone – something that it would be very difficult for a human to do.”
But what about other countermeasures, such as those used by McAfee, which included skin darkening, facial distortion and colouring his hair?
I’m still a fan of CV Dazzle. If you’re going to change your appearance to “jam” facial recognition systems, you can make a bolder fashion statement than wearing a ski mask. Well, I guess Ski Mask is a pretty bold fashion statement, but click over to CV Dazzle for other options that don’t scream “I just robbed a bank.”
Howie Woo also has a more cheery alternative for those committed to the mask, but his approach has its own risks.
