This technology allows people to be identified even through walls
This new technology uses gait analysis, that is, the way of walking to identify people even through walls.
At the University of California, they have found a new technology capable of turning upside down what we knew about people’s recognition. Researchers have created a system that can identify people even through walls, based on the way they walk, which is known as gait analysis.
Normally facial recognition is used to identify people. It is a technology that is already complex in itself. You need intensive training because it will not always capture the subject in the same position, with the same expression or may not fully capture his 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. It can identify people through walls and does so with 80% accuracy. This has been reflected in the tests carried out.
The method takes as a reference for identifying the analysis of the person’s progress. For this, it captures the WiFi signals that are emitted through the walls. These electromagnetic waves bounce and create gaps in areas where there is a person. From there you can sketch the shape of this subject, as well as their 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 was that it had decided: it was the same person.
The accuracy of the system is not complete, but at the moment it is in the embryonic phase. It is not the first time that the identification of people by the way of walking is proposed. Although in that case, the investigation came from the military field.
The system could serve in the security sector. The cameras capture a person stealing but with the face covered. However, by its way of walking it is possible to verify if one of the suspects is the person sought. Although the technology could also be used to automate certain functions, such as the temperature of a room when between one person and not another, or the configuration of the musical thread at work.
