Stemming from the rapid prototyping maker movement, technology has taken a huge leap forward to begin true integrations with the human body. As the human body becomes a natural extension of technology itself, ways of identifying a person to the technology around them is shifting from antiquated external body definitions, to internal body functions. From using heartbeat and vein recognition to uniquely identify a person, to embeddable and injectable body modification to enhance natural body identification, the future of how we interact with technology is vastly changing. We'll explore this movement and see where the future of identity in the human body is going.
