Chip bag transformed into a listening device: Innovative researchers discover covert method of audio surveillance using common household item

In a groundbreaking development, researchers at the Massachusetts Institute of Technology (MIT), Microsoft, and Adobe have developed a method that turns everyday objects into unwilling spy tools. This technology, known as a "visual microphone," was first introduced in 2014 and has since been advanced, enabling objects like chip bags, plants, and glass bottles to convert their vibrations into audio signals.

The principle behind the visual microphone is simple yet ingenious. When sound hits an object, it begins to vibrate minimally, and these vibrations can be made visible by recording them with a camera. By using high-speed cameras that record 2000 to 6000 frames per second, or even smartphone cameras with 60 frames per second, these vibrations can be converted into audible sounds using special software.

In an impressive video presentation, the researchers demonstrated the potential of this technology. For instance, when they played the song "Under Pressure" by Queen, a camera recorded the vibrations of various objects. Surprisingly, even a chip bag could be used as a whispering device, with the researchers successfully capturing audio from four meters away and through soundproof glass.

The researchers also found that other objects like plants, aluminum foil, glass bottles, or water can react to music and have their vibrations recorded. Although the reconstructed sound track was noisy, the algorithm was able to reconstruct the melody so clearly that a music software recognised the song correctly. With lower quality recordings, you cannot understand the individual words, but you can hear how many people are talking in a room and whether they are men or women.

The use of smartphone cameras as listening devices indicates a potential expansion of the visual microphone technology's accessibility. However, it's important to note that the data protection declaration of YouTube is accepted with the loading of the video, and no new vulnerabilities or exposures of sensitive data are discussed.

As we delve deeper into the realm of modern surveillance technologies, it's clear that even harmless objects can potentially become eavesdroppers. This development underscores the importance of data protection and privacy in our increasingly interconnected world.
