If it "was AI" it should be easy enough for him to prove by pulling up his account on whatever AI video generation service he used and showing the generation in his account history.

(I do not think it was AI.)

Also I’d be surprised if the only evidence introduced by the prosecution is the video. There may be other eyewitnesses, evidence of equipment usage, communications with others prior to the event about his intent, and so forth.

Maybe he doesn't have to prove that though. If he can find an expert witness who will make claims that based on their expert analysis it is possible this video is AI generated, and he does not testify himself, then that may be enough to introduce reasonable doubt.

True, and I agree with you on it not being AI, however, the burden is on the prosecution to prove guilt, not for a defendant to prove innocence.

But you are correct, if it was in fact AI, showing how he (or someone else) made it at the time would certainly help get him off the hook.

Guy could've probably picked a better place to base jump anyway, national parks are notorious for having a billion laws that don't really exist anywhere else.

There are lots of places to legally BASE jump in Europe. You can even take a gondola to the jump point. But very very few legal options in the USA.

I wish there were more places to legally enjoy BASE jumping on US public lands.

It's legal by default on US federal land, (e.g. BLM or USFS) which covers about a fifth of the country, and is especially concentrated in areas with mountainous and other earthen terrain that is favorable to BASE jumpers. We just take a very small portion of that land, designate it national parks or forests, make everything illegal there, dump all of our tourists there, and charge them to park.

There's far more to see outside of those national parks and forests than there is inside. Look up any paragliders or bush pilots on YouTube that live near federal land, and they pretty much go wherever they want to go.

If you're an avid hiker or camper and are visiting the US, find local documentation on where to visit or befriend someone in the area who can make recommendations, and you'll get to see our natural landscape without all of the tourists or regulations. You can legally BASE jump off a cliff, hike in the nude, mine for gold, set up an impromptu gun range, and camp there for a couple of weeks, or indefinitely if you hike two miles each day.

This seems like something a liability waiver and an escrow account with money for body clean up (if things go bad) would solve. A little red tape, sure, but not illegal.

I’m convinced this is how Dean Potter died. Jumping at dusk to try to evade capture my Yosemite rangers.

If it had been legal, and had he jumped in broad daylight, I think he’d have survived that day.

Gosh there's a lot of corollary evidence pointing to his guilt but this is likely going to become more and more common and force the use of a lot more technical forensic resources.

Finding an original copy on a go-pro would likely be pretty compelling evidence but this (and the more scary politically centered questions like this) are why I wish we had a way to build a durable chain of custody into these technologies. It is infeasible from everything I've seen but it would be a big win for society.

Put private key into every digital camera and hash/sign every frame. That private key is accompanied with manufacturer signature and can't be easily extracted. Mark all unsigned media as suspicious.

"and can't be easily extracted" is doing a lot of work there. People are very good at reverse-engineering. There would soon be a black market for 'clean' private keys that could be used to sign any video you want.

There's also always the "analog loophole". Display the AI-generated video on a sufficiently high-resolution / color gamut display and record it on whatever device has convenient specs for making the recording, then do some light post-processing to fix moire/color/geometry. This would likely be detectable, but could shift the burden of (dis-)proof to the defendant, who might not have the money for the expert witnesses required to properly argue the technical merits of their case.

More likely, the signing would have to use compression-resistant steganography, otherwise it's pretty easy to just remux/re-encode the video to strip the metadata.

There would also be a requirement for all playback to actually properly check the private keys and for all the parties involved in the process to be acting in good faith. Not only would you have a black market for individuals to scalp clean keys but you'd likely have nation states with interests putting pressure on local manufacturers to give them backdoors.

We'd probably hit a lot of that with SSL if it wasn't so unimportant from a political perspective[1]... but if the thing we were trying to secure is going to boost or damage some prominent politician directly then the level of pressure is going to be on a whole different scale.

I don't think that's true. Only for someone who wanted to prove authenticity to grab the signature. No private keys would be exposed (except those which were hacked.)

If Netflix and Amazon can't keep their 4k HDR webrips from being leaked (supposedly via extracted licenses from Nvidia Shields), I have no idea how we'd expect all camera manufacturers to do it. Maybe iPhones and flagship Apple devices, but even then we'd find vulns in older devices over time.

I was thinking more about the spread of disinformation at large - but yea, that playback requirement would only be necessary for anything that wanted to be considered a potential source and trying to protect against disinformation platforms is a much larger problem then technology can solve on its own.

"can't easily be extracted" = "the number of people who can extract it is small but still non-zero"

And those people now have the power to put you in jail, by putting your camera's signature on illegal content.

You've also just made journalism 3 notches harder. Like documenting atrocities in, say, North Korea. Or for whistleblowers in your home steel mill run by a corporate slavedriver.

Oh. Also. Why are you choosing the camera side to put this on? Why not the AI side? Require watermarks and signatures for anything created in such a way…

…of course that has its own set of intractable problems.

Ideally, the keys would be per-manufacturer, like HDCP or (DVD-)CSS. Personally I don't think I'd love the idea of any kind of attestation like this, but if TPTB did implement it, I'd prefer a key per-manufacturer rather than each unit having its own unique signing key. We do have precedent, in the form of printer tracking dots, which were kept 'secret' from the public for 20 years. [0]

It's ultimately up to juries to decide whether a defendant's assertion that evidence is fake is enough to constitute reasonable doubt in the absence of hard evidence for it. I imagine that's going to be very context-dependent. It would probably work if I was accused of this, with no history of anything like this, versus a guy who does this frequently, posts videos of himself doing it regularly, and never gave any indication they're fake until he got in trouble.

Do you? Consider for a moment all the dissidents and protestors who would be ensnared by their own devices then, with no "it was all ai" defense available?

reply

I do - I think the videos and pictures that protestors smuggle out become less powerful if the state can dismiss them as fake and while most of us will remain skeptical of authority the more easy it is to fake something the more people you can convince of your falsehood.

I don't think the lack of a durable chain of custody really provides any protection - that protection needs to come from a strong legal system and social contract to protect whistleblowers. If you're thinking of, as an example, an Iranian smuggling out protest footage, they're already taking an extreme risk and have a state using numerous tools to try and track them down - but the lack of a durable chain gives a wide area of authorities to cast doubt on the truth.

I think your question is interesting to ponder and I think there are arguments in both directions - but my mind keeps coming back to the tank man photo being smuggled out of China and how much more difficult it would be in the modern world for a single image to carry such weight.

That social contract is quite a bit of a hit&miss if you look at countries across the globe. Same for the strong legal system. Other concerns aside, does this not make the whole approach a non-starter?

I don't think it does but I do see the counter arguments. There have been prominent publicly open political dissidents and they do often suffer from assassination attempts. I think if you're considering political dissent the potential cost is a major factor in that decision. I have not had to make that decision personally so I am not an expert here - but it might be important to consider the value to those people of knowing your evidence can be proven true no matter what the authorities say.
