Privatsphäre ist ein Recht wie jedes andere. Man muss es in Anspruch nehmen oder man riskiert, es zu verlieren.

Phil Zimmermann
Pretty Good Privacy

Wussten Sie,

…dass sich Ihr Handy, Tablet oder Laptop mit LTE Chip in eine Wanze verwandeln kann – und zwar ohne, dass Sie etwas davon merken? Durch die integrierten Mikrofone können Hacker sogar einzelne Unterhaltungen aus einer Menschenmenge extrahieren und aufzeichnen.

Sobald sich ein Mobilgerät im Raum befindet, können Sie kein vertrauliches Gespräch mehr führen. Auch dann nicht, wenn es ausgeschaltet ist.

Es sei denn, Sie vertrauen auf uns.


Zu argumentieren, dass Sie keine Privatsphäre brauchen, weil Sie nichts zu verbergen haben, ist so, als würden Sie sagen, dass Sie keine Freiheit der Meinungsäußerung brauchen, weil Sie nichts zu sagen haben.

Your cell phone, tablet or laptop with LTE chip can turn into a bug - without you noticing anything? With built-in microphones, hackers can even extract and record individual conversations from a crowd.

Unless you trust us.

the Whitenoise Generator

The Noise Generator generates noise in the frequency range of 300 Hz to 8 kHz - covering the entire voice range. It "forces" the microphones of the devices to switch the sensitivity to a minimum level to prevent overdriving.

The generated noise is absolutely randomly in time, strength and frequency. This makes it impossible to recognise any consistency of the noise, thus eliminating thechance of someone rendering the conversation with technical assistance.

The generationof the noise signal is carried out exclusively using analog components (avalanchebreakdown of a base emitter range in a cut-off wavelength).

The device is powered by rechargeable NiMH cells. Cables, batteries and charger are included in the set.
