The SafeCase offers first-of-its-kind defense against the misuse of a mobile device’s cameras and microphones. Integrated audio masking and camera blocking keep valuable audio and visual data in the paired mobile device’s vicinity from being captured via mobile spyware or rogue insider.See mobile hardening in action
Patented audio masking ensures that a captured conversation’s content and context are unidentifiable even when advanced audio forensics techniques are employed.
A physical barrier over each of the smartphone’s cameras prevents intruders from observing or recording any visual data in the device’s vicinity.
Camera/microphone protections can be observed by the user, providing peace of mind even if the paired mobile device has been compromised.
With the ability to enforce camera/microphone policies via MDM, organizations can allow users greater flexibility in their use of mobile devices within secure spaces.
Similar to how white noise machines drown out the audio in a room, the SafeCase adds noise at the locations of the paired mobile device’s microphones. The end result is that the mobile device is essentially deafened, burying any meaningful audio content beneath the noise floor of the masking signal.Download mobile hardening data sheet
The noise is generated using a true random number generator (TRNG), preventing the use of two-channel adaptive filtering to essentially “subtract” a noise profile from a piece of captured audio.
A distinct masking signal is used for each of the mobile device’s microphones, preventing the use of cross-correlation or known pseudo-random patterns to extract audio from the masked output.
The level of audio masking adapts to the volume of the audio in the mobile device’s vicinity throughout the range of human speech, meaning that everything from a whisper to a shout is discreetly masked.
