A device with an always-active microphone inherently poses a privacy threat, and what could be a more fitting example than a smartphone—always listening, always online? To protect your privacy during conversations in the presence of phones, we developed the White Shield mobile app, which turns your smartphone into a portable source of noise interference. The app detects ambient sound levels and generates background noise to mask speech recordings. Use it during private meetings and conversations not meant for prying ears.
What White Shield Can Do
White Shield combines two core functions—an acoustic noise generator and a mobile sound meter. Thanks to a unique algorithm that generates white noise and speech mods, it achieves high levels of masking, making human speech on recordings indecipherable.
Even at lower noise levels, White Shield prevents audio editing and the extraction of phrases out of context. The acoustic noise is generated randomly and cannot be replicated, so recordings will show evidence of tampering and other traces of external interference.
The app is more effective when used with a shielding box, such as a Faraday capsule. For this purpose, the acoustic noise level scale includes a "Faraday cage" mode, which sets the volume high enough to obscure recordings in a small, enclosed space with reflective walls.
To determine the noise level sufficient to mask speech recordings, the app includes a sound meter. You can measure the ambient noise near your phone and adjust the intensity of the white noise based on the data. The app will show whether the current noise level is enough for effective masking.
Pro Tip: The sound meter can be used not only for protecting against eavesdropping and recording. It's an ideal tool for audio professionals and a handy utility for everyday life.
