This technology allows to identify people even through walls


This new technology uses gait analysis, that is, the way you walk to identify people even through walls.

At the University of California they have come up with a new technology capable of turning what we knew about people recognition upside down. The researchers have created a system that can identify people even through walls based on your gait, which is known as gait analysis.

normally used facial recognition to identify people. It is a technology that is already complex. You need intensive training, because you won’t always capture the subject in the same position, with the same expression, or you may not capture their entire face. The systems have been perfected, but there are still gaps to be filled.

However, researchers at the University of California have created a system capable of going beyond facial recognition. He can and does identify people through walls. with an accuracy of 80%. This has been reflected in the tests carried out.

The method takes as reference for the identification analysis of the person’s gait. To do this, it captures the WiFi signals that are emitted through the walls. These electromagnetic waves bounce back and create voids in areas where there is a person. From there you can sketch the form of this subject, as well as its movements.

Taking the data of the movement of the person from the WiFi signals captured , the researchers compared them with a video of theirs. When the system found a clear similarity in the way of walking, it had decided: it was the same person.

Real World Applications

The accuracy of the system is not complete, but at the moment it is in embryonic phase. It is not the first time that the identification of people by the way they walk has been proposed. Although in that case the investigation came from the military.

The system could serve in the security sector. The cameras capture a person stealing but with his face covered. However, by the way he walks it can be verified if one of the suspects is actually the wanted person. Although the technology could also be used to automate certain functions, such as the temperature of a room when one person enters and not another, or the configuration of the background music at work.
