The way you walk, the way your body reflects radio waves, and its thermal signature allow artificial intelligence (AI) to identify you without the help of cameras, writes James Kobielus of Wikibon on InformationWeek .

Computer vision is a privacy advocate’s nightmare. Nowhere is this more evident than in the escalating war between proponents of computer vision (AI-powered facial recognition) and the many developers of innovative countermeasures that use AI to thwart such intrusive surveillance.

Conventional cameras can’t see through walls. So malta whatsapp data computer vision is useless in places where you can prevent cameras from being installed. But just as blind people use their other senses to compensate for their lack of vision, AI-powered computer vision platforms are able to create increasingly accurate visual representations even without capturing an image.

In a broader sense, computer vision is becoming the sum of sensor data that can be represented as visual patterns. With the advancement of AI, it is becoming possible to create a highly accurate visual portrait based on the body’s reflected radio frequency signals, the pressure on the supporting surface, the vibrations created by a person when walking, and their thermal radiation. All of these, individually and together, represent a unique signature that can be used to “see” a person, even if they successfully hide their face, voice, fingerprints, and genome from prying eyes.

It may soon no longer be necessary to install cameras everywhere to piece together a good enough picture of what's happening indoors and outdoors. Here's a quick look at the innovations emerging from recent research, most of which use advanced AI.
