New research could allow our physical behaviour to be used as a secure way of logging in to our computers and smartphones, a team at the University of Oxford say, claiming that they can also detect when a person is drunk or has had sex.

Researchers have identified that every individual creates a unique pattern of physical behaviour including the speed at which they type, the way they move a mouse of the way they hold a phone.

About 500 different behaviours are unique to every individual and, taken together, form what they call “eDNA”, or electronically Defined Natural Attributes. Changes in this string of physical behaviour might even be able to signal when someone has taken drugs, had sex, or if they might be susceptible to a heart attack in three months’ time.
