The USPD is the most advanced and unique system to provide complete protection from the information leakage. Not all eavesdropping devices can be detected by existing methods. Remote-controlled radio microphones, wired microphones, passive resonators, miniature voice recorders – almost all these devices cannot be detected by traditional methods. Even modern cell phone may have a digital voice recorder. That means that any phone, lying on a table or in a pocket, can be used by an adversary to record a conversation or transmit any acoustic information.
It is extremely important to have a reliable privacy protection device. The concept of the USPD information protection device is based on the generation of ultrasonic and sound interference simultaneously with human speech. The ultrasonic emitter of the device completely blocks modern ultra-high-quality microphones, while acoustics, even in low volume mode, successfully fights with any analog and outdated systems of poor quality – all of which provide complete protection for the interlocutors.
The unique audio clutter cannot be eliminated by using any recording clearing methods.
