Description
While developing this product the following features and vulnerabilities of modern mobile phones were taken into account:The smart phone can be intentionally, or covertly, off-hook during important negotiationsVoice recording software can intentionally, or secretly, run on the smartphoneListening software can run in a stealth modeSpyware can be installed on the smartphone without the owner's knowledge, allowing attackers to activate covert eavesdropping around the phone. There are known cases of transmission of such software by exploiting the vulnerabilities of some messengersThe acoustic environment around the phone can be transmitted to the server, or cloud service of the attackers either in real time or with a postponed uploadingSmartphone apps which have access to the phone's microphone can be used for eavesdropping in cases of them having been hacked (usually messengers or social network apps)Uploading of information can be done in the following ways: Conventional voice call; Mobile internet; Wi-Fi; Bluetooth; The phone's connectorOther audio security devices use radio interference to protect conversations. Unfortunately, the creation of radio interference (RF jamming mobile communications, Wi-Fi and Bluetooth) does not guarantee protection: there is still the possibility of accumulating information in the phone's memory (voice recorder mode). Given this factor, the only reliable way to protect is to block the phone's acoustic channel. This prevents acoustic information from leaking, regardless of how it is listened to or transmitted. A number of modern technologies have been used in the PHONE SAFE ULTRA device for your protection.Features and advantagesBlocks the microphone of the phone with the help of non-filterable ultrasonic interferenceEfficiently prevents surround recording app from capturing conversations and soundsThe frequency of interference has been optimally selected for the best performance and affects all existing models of smartphonesMade with t
