Technical Details of Deniable Video


Deniable Video is a hardware/software system that captures, stores, and plays back audio and video. It has a unique privacy feature: the stored audio and video is deniable. That is, not only is the content securely encrypted, but it is stored and encrypted in such a way that even its existence cannot be proved.

Hardware Components

Deniable Video has four hardware components:

The Deniable Video system continuously encrypts and stores all the audio and video that it receives. Before you can watch the video, you have to insert a USB thumb drive into your computer containing the DV viewing software. You must enter a passphrase to access your DV system. The DV system transmits the encrypted video to the viewing software and allows you to view the video.

Video is decrypted and viewed only on your computer. The "private key" necessary to play the video is never available to the Deniable Video system. This private key is created on your computer, is used only on your computer, and stored on the USB thumb drive.

This design ensures that if the Deniable Video system is lost, stolen, or its hard disk copied, no video is ever recovered from it. It ensures that an adversary cannot determine that video even exists. Even a very sophisticated adversary — such as a foreign government using computer engineers, cryptographers, and forensic tools — will not extract any video.
