I would imagine that in the future video encoders will start to automatically include a cryptographic signature every X frames, which then players will become aware of and show an indicator for "original / modified" content.

It'd be too easy to fake, just replace the sensor in an approved camera with your own data feed. And that's assuming it wouldn't be somewhat trivial to dump keys from one or more cameras on the market to create a an easy tool or resignvideo.com... which is a massive assumption. As the movie industry has already seen, cryptography doesn't help you when you push out the keys to everyone. It'd be about as effective as D…

Invisible watermarking can be encoded into video frames.

I remember visiting the MIT media lab when I was in college, they described the audio version of "invisible watermarking" - manipulating the source audio with a generated acoustic effect, similar to a doppler shift. The effect is not detected by the human ear, but signal analysis can translate it into binary metadata, such as a DRM signature.

What's the relevant application here? If you're suggesting this could be added by video editing software or display hardware, it seems if everyone knew about such watermarking it'd be trivial to strip out and turn into noise, so it would work publicly exactly once.

If you're saying it'd be added by legitimate camera sensors, well it wouldn't beat the possibilities I suggested already of simply feeding tampered data to the sensor.

As it was described to me, the watermarking is encoded in such a way that it would be prohibitively expensive computationally to offset or overwrite it.

I don't follow ?

I believe it's a reference to a general effect of regulation, which is by making the business being regulated more expensive due to following regulations, it prevents smaller businesses from popping up to potentially displace the larger business. For a generally positive example of this, see a good chunk of the history of Silicon Valley with smaller tech companies displacing larger companies like IBM, because there w…

And sooner or later, Uber will start proposing regulations for that same reason: to avoid competition.

This is multi-layered problem with no simple answers but many comments here touch on solutions, note there will not be 1 solution. Here are a couple of concepts I know are being worked on

- Secure Data at the Source -

Public Created - I have seen some demo's of phone apps that put video and pictures from phone directly on the blockchain with gps, time stamps etc.. Also have heard of dongles being added to phones

Professionally Created at Device - have read about hardware getting processors to secure data directly on the blockchain at the device.

Created at Editing Software - This could be connected to the identity of the original on the blockchain and then the edited version has notes with it and added to the blockchain as an edited version of the first.

Security cameras for Customs and Border Patrol are getting blockchain capabilities added per this quote - " Factom (blockchain) has integrated their technology into two brands of cameras used by CBP at border locations to ensure data collected from these cameras is tamper proof" - http://www.activecyber.net/dhs-st-lays-out-a-broad-yet-innov...

IoT Devices - This micro processor can be added to an IoT (raspberry pi and the like) device and secure data the source - https://iot-sas.tech/

Professionals (media) and citizens can then have proof of what and when they created the video and potential a certification can be added in manor and tool for others to check the video is in fact the original.

None of the above completely solves the issue but with implementing these and having standards the public can start to trust what they are watching is authentic.

To any one who reads this, don't actually do that. I wouldn't put it past Facebook to file a serious lawsuit against you. If it spread far enough, you could cause serious damage, and the SEC might even get involved.

If I were going to do this, and I thought it would cause such a storm, I'd take a raspi wardriving and find an open router somewhere, and then upload it via TOR to liveleak or imgur or something like that using an old netbook sourced from Craigslist. Then wipe the devices used and sell 'em back on Craigslist, or drop 'em off at Goodwill or some recycling company. Plausibly deniable and all that.

Some one's been watching too much Mr. Robot... for what it's worth, don't bother with imgur over tor; they block uploads from those ips. You can, however, use the lunapic upload to imgur feature. Public library also might be an option, though I might reccomend i2p. Whether it's really "more secure", I dont know, but it doesn't have the same mainstream knowledge (or use by journalists), so three-letter guys would be slower to break it.

I am so tempted to reply with a BS. Because this is a super hard problem, with hundreds of edge cases making it even harder, some tried to solve it in the past, with underwhelming results. Yes, this is utter BS, sorry.

If you're gonna call BS, just do it! I am curious to know more about this space because it's all very new to me. What failed solutions were tried in the past? Which issues does Truepic fail to address? And is it even possible to address these failures?

Truepic doesn't solve the problem of you taking a picture of your neighbors flooded basement or broken windshield. GPS can't fix the problem as its not accurate enough, and for quite a few places is not odd if you park somewhat close to your neighbors house.

One thing I don't see talked about much is the Uncanny Valley. No other technology has made it past it and looking at these they definitely have not either. Is there any reason to think that "deepfakes" will leapfrog it somehow?

Yes, these may be still in it, but they're climbing out. They're not leapfrogging it, they're just getting slowly better, inching further until they get past the valley.
