Adding extra layer of security through ultrasound authentication step (engl.)

The ability to guarantee the physical proximity of a device in an authentication process gives an extra layer of security. Ultrasounds‘ unique wave characteristics, as compared to other mediums,
gives this alternative security step an added strength. In this talk, I’ll discuss scenarios where ultrasound authentication can be added using existing built-in audio components and a light-weight software package that we’ve built at DEJ Technology.
