>Isn't this already happening maybe? I recall an article posted 1-2 years ago about a camera company (Kodak? Can't remember) which was starting to offer something along these lines. >the companies providing these cameras should be trustworthy, and that the camera's are actually really sending what they actually record, and that the company itself doesn't mess with the original recordings. I agree. We can't guarantee any of these things, but on the bright side, the incentives are pointing in the right direction to make self-interested companies choose to behave the right way. It will complicate things and make the hardware more expensive, so I doubt it will sweep through all consumer camera tech unless the "Is this photo real?" question becomes a crisis. There's also the fact that it would be possible to give individual cameras different private keys, with certificates signed by the manufacturer: This would enable non-repudiation (you would not be able to plausibly deny that you had taken a particular photo/video), which has potentially big upsides but also privacy downsides. I think that could be solved by giving the user the option of signing with their unique camera private key (when the user wants to prove to others that they took the photo themselves) or with the manufacturer's key (when they want to remain anonymous).
