Soon Your Walk Could Help Give Away Your Identity

Researchers at Spain's Universitat Jaume I are working on a technique that collects several different images of a person's silhouette in motion and builds a unique "gait signature."

What's the Latest Development?


Ramón Mollineda and his team at Spain's Universitat Jaume I are developing a system that uses key aspects of a person's walk to build unique identification data. It works by collecting a series of silhouettes provided by video data and placing them on top of each other to create a summary image or "gait signature." Together with physical appearance, the final representation can be used to help identify the individual.

What's the Big Idea?

There are notable advantages to having a surveillance system that's smart enough to recognize a person by their walk alone. However, Mollineda is careful to stress that many different factors can affect that walk, which is why the system his team is developing is meant to complement other, more reliable biometric techniques, such as facial recognition. "[T]he way you walk can be detected from a distance and does not require a high-resolution image...while face recognition is performed close-up and with a high-resolution image. In this way, surveys could be carried out in a wider range of conditions or, if both methods are applicable, results could be more reliable thanks to contrasting hypotheses about the identity of an individual generated by two biometric systems."

Are we all multiple personalities of universal consciousness?

Bernardo Kastrup proposes a new ontology he calls “idealism” built on panpsychism, the idea that everything in the universe contains consciousness. He solves problems with this philosophy by adding a new suggestion: The universal mind has dissociative identity disorder.

There’s a reason they call it the “hard problem.” Consciousness: Where is it? What is it? No one single perspective seems to be able to answer all the questions we have about consciousness. Now Bernardo Kastrup thinks he’s found one. He calls his ontology idealism, and according to idealism, all of us and all we perceive are manifestations of something very much like a cosmic-scale dissociative identity disorder (DID). He suggests there’s an all-encompassing universe-wide consciousness, it has multiple personalities, and we’re them.

Surprising Science
  • Seven individuals were locked inside a windowless, internetless room for 37 days.
  • While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
  • Morning time again shown not to be the best time to eat.
