Italy’s capital located in Rome La sapienza university Researchers have developed a technique that Wi-Fi surveillance technique Can bring a new revolution in the field of. This technique is named ‘Whofi’. Its biggest feature is that it can identify without any camera, microphone or any kind of visual device whether a person is in the room or not, and if it is, he is sitting, running or standing.
Wi-Fi surveillance technique The wireless signal spread in the room is analyzed. When a person comes between these signals, his body absorbs some signal and deflects some. The direction of every body’s texture and movement varies, causing subtle changes in the phase and amplitude of the signal.
Whofi records these changes through neural networks and special algorithms. To train this technique, scientists used a dataset called NTU-Fi, which Wi-Fi surveillance technique For the standard testing set for.
The WHOFI technique has been trained at such a high level that it can identify a person with an accuracy of 95.5%, that too when he moves from one room to another. This technique does not use any camera or microphone, which makes it different from other monitoring devices. But this also becomes a matter of its biggest concern.
While this technology provides unique benefits in the field of safety and monitoring, on the other hand it can also become a big threat to people’s privacy. Even when there is no camera or microphone, the idea of someone’s movement can be uncomfortable.
Researchers have clarified that this technique does not collect a person’s biometric or personal information, but this cannot be said to be completely satisfactory when it is evident.
Wi-Fi surveillance technique Can be used by security agencies to identify suspicious activities in public places, airports or border areas. This technique can also track a hidden person, who can hide from traditional cameras.
This technique in the health sector can be useful for patients who require frequent monitoring. If an elderly person suddenly falls, this technique can give alert. In addition, this technique in smart home systems can touch new heights, such as automatic light on/off, controlling temperature based on movement, etc.
However researchers say that Wi-Fi surveillance technique Only the movement of the movement is based on the pattern, but it can also be very easy to misuse it. If this technology is made publicly available, cyber criminals can also take advantage of it.
Therefore, it is very important that strict rules should be made for the use of this technology and transparency should be ensured in which place and why this technique is being used.
Techniques like WHOFI are extremely inspiring in terms of science and shows what extent human intelligence can overcome the boundaries of technology. But every technique is also associated with responsibility and morality. Wi-Fi surveillance technique If used in the right direction and with regulation, it can prove to be a boon for the society. But if its uncontrolled use started, then it can also become a new way to dent in our personal life.
