Cocon-IBT is acoustic safe with the option of  blocking Blue-Tooth channel.

The device was designed to protect your cell phone against unauthorized interception in the mode of remote information access.
Cocon-IBT is intended to protect speech information circulating in the places where the owner of a cell phone stays. It is applied in case of its unapproved remote activation to intercept via cellular communication channels as well as to protect against potential information leakage through the "Blue-Tooth" channel.
The device consists of several blocks working independently.
In case of unapproved remote activation of phone in interception mode, there is only one give-away characteristic which is change in the electromagnetic field (i.e. mobile phone transmitter switches to unauthorized transfer). This change is recorded by the field indicator to give a command to automatically activate acoustic noise generator which is located inside the Cocon-IBT. The level of acoustic noise at the input of handset microphones is enough to provide guaranteed closure of this channel of information leakage, i.e. the entire transmission path of speech information is blocked  in the way that there are no signs of speech at the receiving end.

The activation of acoustic noise generator indicates unauthorized connection to the phone and start of information exchange between handset and the base station of cellular communication. Noise generator is activated with the pause of 5 calls.

After cell phone handset is placed inside a cell phone case, the detector recognizes it and activates noise generator. If when a regular call occurs, the owner picks up the phone – the work of noise generator is not allowed. 

When trying to establish connection with a cell phone through the Blue-Tooth channel, the device automatically activates noise generator in the range of 2.3-2.5 GHz (3dBm), which blocks data exchange between phone and another BT device. The operational duration of the generator is 30 seconds. When blocking information exchange via BT channel the phone itself can be visible to external BT devices.
