If anyone tells you that your Wi-Fi can track you, are you going to believe you? Wi-Fi can track all the information of what you are doing, where you are standing, where you are sitting. Yes, this is true. You may have remembered the occasion of a movie. But now the occasion is going to come true. Now Wi-Fi will be able to track you. Researchers of Rome’s LA Sapienza University claims that the movement of the room can be tracked with the help of signals coming from Wi-Fi. Whofi technology is used for this.

WHOFI technology works without any cameras, microphone and other devices. It has been claimed that the technology track the movements of the person present in the room. This technology is easily recognized by the movement of the technology wireless signals. Let’s learn how the whifi technology works. (Photo courtesy – pintterest)

How does this technology work?

When the Wi-Fi signal spreads in any room, objects such as walls, furniture and humans are covered and included. After that, each person’s body, his size, height, moves affect the signal in different ways. Whofi recognizes these changes. It records the technical aspects of the signal’s “employed” and “phase”, and then recognizes the person’s patterns through the neural network.

This datasate is called Research NTU-Fi, which is used in a standard testing in Wi-Fi sensing technology. They have trained the system to identify the person in the room even after moving from one room to another or in a different place. The accuracy of this technology in re -identifying a person has reached 95.5 percent. Although this technology is beneficial, questions are now being raised about users’ privacy.

The specialty of this technology is that it clicks the photo and records no voice. Therefore, this technology is considered to be more private-friendly. But the danger is not completely avoided. Because this technology can track anyone’s presence or movements without their knowledge, so many moral questions about privacy and consent. With the help of this, people can easily be monitored.

Researchers have claimed that Whofi technology does not directly collect biometric or personal information of any person. But with the help of this technology, people’s homes, offices or public places can be traced. Currently, this technology is limited to the Research Lab. This technology is not implemented at any government or commercial level. But since Wi-Fi is normal in every home and city, such systems can be used in smart security, health monitoring and home automation.
