Clearly forged video footage was submitted as evidence recently regarding an international crime investigation. The forgery was detected because it not smoothly done. But that is changing. So while the countries involved might seem out of the way, recent news about algorithm-enhanced falsified video footage and the social and legal repercussions of realistic but completely fabricated videos make this kind of a warning shot for the admissibility of recordings in general.

Regarding the particular case in question and the forged video, YLE reports:

Aliganyira said that local police were using doctored footage which contained "insertions, removal of images, creating someone to look like [the victim] yet it wasn't him."

Earlier, The Daily Monitor had reported on the footage.

The Internal Security Organisation (ISO) on Tuesday said the footage that is currently in the hands of security and intelligence agencies on the death of the Finnish national who died at Pearl of Hotel on February 6, in Kampala was manipulated.

Already, realistic voice forgery can be done affordably. Soon video capabilities will be realistic enough to cause real difficulties. Then investigations will depend even more so on advanced forensics, if audio and video are even still admissible. Realistic forgeries also allow real snakes to stir up denials and long delays when real evidence is produced by asserting that it is "fake news".

Discord Takes Down "Deepfakes" Channel, Citing Policy Against "Revenge Porn" 27 comments

The messaging platform Discord has taken down a channel that was being used to share and spread AI-edited pornographic videos:

Last year, a Reddit user known as "deepfakes" used machine learning to digitally edit the faces of celebrities into pornographic videos, and a new app has made the process much easier to create and spread the videos online. on Friday, chat service Discord shut down a user-created group that was spreading the videos, citing their policy against revenge porn.

Discord is a free chat platform that caters to gamers, and has a poor track record when it comes to dealing with abuse and toxic communities. After it was contacted by Business Insider, the company took down the chat group, named "deepfakes."

Discord is a Skype/TeamSpeak/Slack alternative. Here are some /r/deepfakes discussions about the Discord problem.

One take is that there is no recourse for "victims" of AI-generated porn, at least in the U.S.:

People Can Put Your Face on Porn—and the Law Can't Help You

To many vulnerable people on the internet, especially women, this looks a whole lot like the end times.

    A child's wish for the ultimate porn experience, corrupted by the adults for foolish aims! Finally, the courts will treat video evidence as less objective (as if it ever was!). If only this technology was here sooner, Trayvon could've kept his skittles.

    As a public service announcement, remember to download yourself a copy of Deep Fakes and load it up on a VPS with a Nvidia card. Then multiply and flourish! The time is now, make video so useless for anything truthful, that no one would dare use it again for "news" or "justice." Make it prolific, otherwise governments will get there first and create the ultimate propaganda! No longer does China need to force their indentured foreign captives to exclaim on national TV: "Yes, I am good. I do not wish my country to come find me." Now, they can rough him up as much as they wish, and just send in a double for the voice, and overlay the captive's face on his face!

    If anyone knows anything about porting CUDA software to other cards, please let me know. I've had no luck with looking through Nvidia emulators.

    If surveillance camera recordings become generally inadmissible in court, will they remove the ubiquitous cameras?

    Or will they start manning them around the clock to work with eyewitness testimonials instead of the actual recordings? I gather this would not work for very long either, as technical capabilities improve - but I still think it would be an improvement over the current situation.

      Perhaps they'll have people that can testify to the validity of their records, that the recording being submitted has been in continuous custody of the department and was at no point tampered with. Just like they (are supposed to) have today.

      At no point that I am aware of has even the most credulous and inane US court accepted the naive notion that video cannot be altered. Courts are quite familiar with the notion of doctored evidence, and nothing is just presumed valid on its face without testimony to make it admissible. Meaning you typically don't even get to show the court a videotape until after you bring in the witness who says 'I was sitting in the chair watching the monitor at that particular time and place and this is what I saw, and yes there is a videotape available' or something to that effect.

      Police investigators, of course, may be desperately eager to look at anything that might be relevant, but just because they look at it doesn't mean it ever makes it to court.

    Ok, I expect clueless journos to sensationalize... but come on now, I don't believe any of the S/N submitters or editors will be granted any prize for fiction prose or scifi, at least not based on the stories pushed on the front page of S/N.

    Reading the linkoes in TFA related to the case (shudders), you'll see that none of then suggest the inserted passages are generated algorithmically.
    Where those speculative twists of "realistic voice forgery" (no sound on the footage) and "video capabilities will be realistic enough to cause real difficulties" come from? Certainly, not from Uganda!

    The Ugandan "Daily monitor"

    The ISO Director of Political Affairs Lt Col Joseph Aliganyira told a press conference at the ISO headquarters in Kampala that there are video clips that were inserted into the hotel CCTV footage.
    ...
    “It was manipulated. There were a lot of insertions, trying to create someone who looked like him [the deceased Finnish]. One has a bald head but the other doesn’t,” he said.

    Without saying who gave them the video, Lt Col Aliganyira told journalists that the footage handed to them has both CCTV and High Definition resolution footages.
    “We are still investigating why the footage was manipulated and we shall eventually release a final report,” he said.

    It seems to me like a forgery using low tech mean, possibly - photo-realistic hair [khanacademy.org] is 2012 technology.

    The yle.fi

    "Some people treated us to some funny information from a certain video photography trying to divert us from the right information," the ISO'S director for political affairs Joseph Aliganyira said, according to Softpower.

    Aliganyira said that local police were using doctored footage which contained "insertions, removal of images, creating someone to look like [the victim] yet it wasn't him."

    The ISO claims that the doctored video had been recorded in high definition while the real footage was captured using lower resolution CCTV cameras.

      Correct. None of the changes talked about in the current case was generated algorithmically. That's one of the reasons why it was detected. The thing to note is that someone(s) tried to pull off a forgery anyway. The stakes are high enough in this case that someone tried a long shot. When they get better tools later this year and still better tools next year, and even better the year after that, the forgeries will get harder to spot and probably much more common. So similar cases will more likely to temp crooks into forging video or audio. Forensics will probably still be able to discern real from fabricated recordings but if it is good enough to avoid suspicion and thus the attention of a forensics team then it is good enough to not matter.

      Because forgery is getting easier and easier by the month, eventually there will be a crossover point at which it'll be very difficult to detect. The time to figure out what to do about that is coming up soon and this attempt shows that the threat is not theoretical.

        Have each security camera calculate a cryptographic hash of each frame it records in real time, and immediately publish it to a public repository that can be read by anyone, with several copies being stored by several independent organizations. That would make tampering the evidence much harder, as you'd have to doctor the images right as they are taken; any later addition would make the image hashes not agree with those in the public archives.

          Two pieces of news pointing a direction.

          Most people can see a thrown object and calculate where it will be in a moment based on where it started, how fast it launched in a particular direction, and the rate of change based on several vectors. Surprisingly most people can't do that even with a small amount of other data, not even plotting to points and drawing a line as in linear regression. Tracking first and second derivatives seems to be off the table. (Can't say about the upcoming tablet-raised generation though. They're probably even worse. Word is they aren't coordinated enough to even hold crayons or pencils)

              Yes, neither hand-writing nor signature forgery are new. You have a point and there is a long-established whole, called diplomatics, dedicated to the study of documents and assessing authenticity or lack thereof. However, with what has been seen in the last decades, level heads are not prevailing when computers become involved. it is enough to append "... with a computer" to just about anything all sense of proportion gets thrown out the window. It may or may not affect evidence proper. You say it won't. I say it might. I say also that it will greatly facilitate trial by social media.

              But, yeah it's too early to tell for sure though I see it heading in a particular direction clearly enough that I'm convinced for now.

              I'm not even a little confident that rational thought will prevail in the matter of forged video and audio evidence. Anything even remotely about computers, like what happened to Steve Jackson Games [sjgames.com] just because of their cyberpunk modules gets treated irrationally. Even the infamous social engineer, Kevin Mitnick, had the full force of his government descend on him "because computers".

                Speaking of "signature" and "on a computer", cryptographic signatures are easy to compute and very hard to forge.
                It's a small technical matter to equip the cameras with chips to compute and stamp every frame with a crypto signature and require, for a trusted recording chain, the camera and the recorder to be operated by two separate independent orgs (anything else being not trusted in justice). Perhaps "the cloud" may have some good uses.

                The considerations above can be traced to "what makes photos/videos captured by mobile devices admissible as evidence?" [attorney-myers.com] (relevance and authenticity). In the present, the GPS coordinates, time-of-day, the details of receiving/publishing the clip on youtube/facebook etc, lend a photo/video enough credibility for authenticating it - mainly because they are handled by independent parties or by means outside the control of the operator

                To my mind, it doesn't matter if it becomes easier to fabricate the visual part of it as long as the authenticity of it goes beyond resemblance (i.e. it looks like that person) and authenticity is very hard to fabricate - crypto means are quite good for this.

                  I'll leave that to others. It probably needs some months of dedicated thought to come up with several possible solutions that could possible withstand the first round of pre-peer review. Any hash functon speedy enough to run real time, frame-by-frame in an affordable camera is probably weak enough to allow collisions when set upon by real hardware.

                  ... with a crypto signature and require, for a trusted recording chain ...

                  Hmm. That appears you are saying "blockchain" even you do have a lot of words there to try to hide it. I assume the standard rules of order apply here. Gan bei.

                    $27 [digikey.com] at retail price. In ASIC implementation, probably in the <$10 range per chip for a 256bit signature, I'm quite tempted to say in the $1 range more likely than $10 range

                    Besides the collisions aren't as relevant for signatures as you may think: to insert a replacement that signature-collides with the original frame and does show something visually recognizable (instead of just visual noise) is computational expensive. Even more so if you want a substitute frame that needs to show a person against the same background but doing something else. Do it for every frame for some minutes of footage and the expense for an attacker becomes prohibitive
                    (remember, there's no absolute security, it is only a game of "with cheap means, make the would-be attack too expensive to worth being carried").

    No, that is not changing. Unless someone with an interest has a time machine, but if that were the case, it wouldn't have been poorly done, now would it?

      Depends: What exactly is "the forgery"? What if someone hacks into the court's system and edits the forgery in place? Is that then the same forgery, but changed, or it is a new forgery?

        Doesn't matter, it won't work at this point without a time machine. Too many people have examined it and talked about it and even written about it for the fake to be believed.

        Fakes are only effective when they are believed.
