• Resumen

  • A wearable device prototype could let voice-controlled assistants like Apple's Siri Or Amazon's Alexa recognize their owner and stop them taking orders from anyone else. The VAuth device, developed at the University of Michigan in Ann Arbor, uses an accelerometer that can be hidden in a pair of glasses or worn around the neck. This measures the vibrations created as they speak. An algorithm then compares those vibrations with the received audio command. If they match, the message is received as normal. If not the assistant is blocked from responding.
