Digital video camera with strong encryption. When confiscated, can't be viewed.
I'm watching a documentary about a man that buys guns in the US and smuggles them into Kosovo, past UN security. The film carried would certainly land those in the documentary in jail, and in some countries would put
the filmmaker in jail as well or worse. If there was a camera that recorded encrypted video, this would be less of a risk.
Decrypt using an encryption key on a memory card, which is left at home.

I'm worried about what happens when you're only recording your family vacation (to Unfreeistan) and are jailed by the Unfreeistanis for posessing potentially subversive content. "It's just our vacation! Honestly!" |
|
| |
This would be useful for still cameras, too. |
|
| |
In addition to the crypt feature, there should be an easy way of toggling which datastream images get sent to - the harmless, searchable, visible one or the inaccessible crypto one. (For stills, maybe one could just push them to crypto storage after reviewing them as normal; an alternative to "delete".) |
|
| |
It would be a nice touch if the video encryption were performed in such a manner as to cause playback of the non-decrypted video to display as the random "snow" of a television that is receiving no signal. "Hey, I wasn't really taping anything. Look for yourself." |
|
| |
I think it likely that that is exactly as it would look. |
|
| |
The encryption should happen right at the sensor so that the entire path is encrypted. |
|
| |
Method, opportunity, motive - mark me, [world], this one *will* happen. |
|
| |
What I'm trying to decide is whether or not you'll want your name on it when it does. |
|
| |
Really clever encryption would render the result looking something like a normal video, but buried inside is the real video. |
|
| |
Yes, that's what I had in mind. Except, so far, I believe it is hasn't been applied to video. |

Did you see the low-grade footage from the Iraq war using satellite technology? It would take weeks at that data rate to upload film quality media. |
