Review our startup: Deniable Video
thaumaturgy: Ah, I see. They've separated the storage of software and the storage of video into two separate devices. The unit arrives with its video storage area filled with "random" data, and then the encryption process for the video writes into the video storage area.As long as the encryption methods used produce data which cannot be differentiated from pseudo-random data, then it's impossible to tell whether there's any video on there at all.Pretty neat. :-)
