That's a conclusion from Metaphysic.ai, which specializes in 3D avatars, deepfake technology, and rendering 3D images from 2D photographs. In tests it conducted using …

      Re: Security ID

      The quarter profile picture is at least 50 years old and used by a number of official IDs around the world.

      I never stopped to think what their advantage is, if any. I do wonder now.

    Are there any stories yet of somebody remotely unlocking a front door based on a deep fake of a loved one?
