Can We Kill Fake News With Blockchain? (computerworld.com) 164

"One of the more unique future uses for blockchain may be thwarting fake news," writes Computerworld's senior reporter, citing a recent report from Gartner: By 2023, up to 30% of world news and video content will be authenticated as real by blockchain ledgers, countering "Deep Fake technology," according to Avivah Litan, a Gartner vice president of research and co-author of the "Predicts 2020: Blockchain Technology" report... "Tracking assets and proving provenance are two key successful use cases for permissioned blockchain and can be readily applied to tracking the provenance of news content...."

The New York Times is one of the first major news publications to test blockchain to authenticate news photographs and video content, according to Gartner. The newspaper's Research and Development team and IBM have partnered on the News Provenance Project, which uses Hyperledger Fabric's permissioned blockchain to store "contextual metadata." That metadata includes when and where a photo or video was shot, who took it and how and when it was edited and published...

Blockchain could also change how corporate public offerings are done. Many private companies forgo a public offering because of the complexity of the process. With blockchain ledgers, securities linked to digital tokens could move more easily between financial institutions by simply bypassing a central clearance organization.

The article also envisions a world with encrypted digital online credentials on a blockchain ledger that are linked back to the bank, employer, or government agency that created them.

Ken Elefant, managing director of investment firm Sorenson Capital, sees this technology creating a world of super-secure profiles where "only the individuals or companies authorized have access to that data -- unlike the internet today where you and I can be marketed to by anybody,"

    No, you cannot kill fake news, because it can be created out of nothing.

    And you don't need a blockchain to authenticate real news. Just have it signed by a trusted party.

      Not exactly, The problem is trust. And if you don't trust the party that authenticated it, then you gain exactly nothing by having it signed by a single party.

      The idea of blockchain is to replace trust in a single party by a chain of signees who each vet for the accuracy of the piece of news, and you can always follow the chain back to the original source. Instead of a single instance of true and false, you have a long list of instances (maybe with different levels of trust), and you can attribute a trust

        If you want to have the news signed by multiple parties you can do so without having a blockchain.

        Also, the value of signing a piece of news drops when the parties are further away. If CNN makes a video of Trump, I can see value in both CNN and Trump signing the video for authenticity, but there's little value in a different party adding their signature as well.

          That's not how blockchain works. CNN might be a primary source for some news, but in many cases, they take news from other news agencies and report about them. In this case, CNN is a secondary source, and while CNN does refer to the source they got that piece of news from, they can't vet for the source to be the original source in many cases. If for instance, we have an eath quake in Pakistan, CNN has not an own team close to the epicenter. Instead they have to rely on what the official news agency of the p

If the second one gives the first one a .9, and the next one gives a .8, then we get a .95 and so on, we easily come to .5 a.k.a "take it with a grain of salt."

                Same problem. A bunch of unknown parties giving their blessing has no value to me. Besides, most stories published by big news media, such as CNN, don't have many parties involved. There might be a few unknown witnesses interviewed on the street, and then a bunch of CNN employees, and then it appears on the TV or their website.

                And at the same time, this hurts legitimate civilian reporting. A dude with a cell phone recording some police brutality has no blockchain, so we should dismiss it as probably fake ?

                  Just because CNN produces a news piece it doesn't mean that CNN is the original source. CNN is also relying heavily on other news agencies, a vast network of correspondents and sources. And each of it has a different level of trust to CNN.

                  The idea of blockchain is that you in generel vet the veracity of CNN, and CNN in turn vets its sources, which in turn then report how much they trust their sources. You will never know exactly how much you can trust the original reporter, and even CNN has to rely on int

                    These unknown sources and correspondents have no value to me. They have no stake in the game. At least CNN (and the other big news agencies) have a reputation to protect, so their signature is worth something (not necessarily a lot, but something). Also, the signature of well known people in an interview could be useful as a guarantee that their statement on the final product is an accurate representation of their position, and that the video has not been taken out of context, or deepfaked.

                      Or you build a network of trust, where you trust someone more and someone less. and thus you trust their trust to others again on different levels.

          It's not like big news agencies were anything but press release aggregators for lobbyists, propaganda, etc.

          My dad is an old school investigative journalist. He went undercover in terror groups and real pirates, regularly flies to war zones and places where foreingers are shot on sight, unearthed and did prove the crimes, corporations and governments, amd got almost killed more often than he can count.
          And nowadays, he has big problems selling his work (usually 30-60 minutes docmentaries or 5-15 pieces) because the news agencies and TV stations don't want to upset any of the big corporations and poliitical interest groups. He regularly gets told "It's too risky.", to which his reply is "That is the point! That is what we are here for!", or they say "Your proof is great, but their legal power is greater. They might not win in court, but they would drag it out until we are dead anyway. We can't afford the legal battles.".
          They want light entertainment fluff pieces. That look investigstive, but never actually break the surface.

          Frankly, the only place where you can still get real news, *is* the Internet. Or comedy shows.
          The art is to separate the lies from reality. *Only you yourself can do that.* Anyone between you and them is doing it for his own agenda too. So beware.
          Luckily, my dad is a trained journalist with decades of experience.

    It's not exactly a new idea, here it is documented back in 1996: Ewiges Logfile" [donnerhacke.de]. But I wouldn't hold my breath waiting for them to adopt it. Your average news organisation can't even figured out the hyperlink. Even if an original source is available on the net, they hardly ever bother to actually link it. All they publish is their own stuff with their own little spin on it. Videos are edited, photos are cropped and selected, study results get often twisted into the opposite and the user is never informed of where all that information came from in the first place.

    If you want to stop fake news, you have to stop mainstream news organisations first, since they are the ones that like to spin and twist everything around. Reporting the truth is a noble goal, but it's one with very little commercial value, click bait and spin doctoring is what sells and I don't expect that to change anytime soon.

    The problem with this sort of thinking is it assumes that the algorithms to create and test the hashes are going to be unbreakable or so complex that it'll take a million years to brute force. We've already seen progress into quantum computing that has the potential to calculate all possible hashes at once and this theoretical research will eventually find its way into a public cloud to be rented for pennies per hour.
    Furthermore, it ignores the fact that simply stripping the metadata, faking its contents with things like deep fakes, or simply placing scrolling news feeds and logos on the bottom are enough to break the chain but possibly maintaining the authenticity from a true/false perspective. While it would make sense for organizations to update the chain with their modifications, the authority to be a "certified" organization with access to the chain will likely create either competing chains or worse, concentrate what counts as "real news" only coming from a select, for profit, organizations that have an incentive to limit access and control the narratives. Think about this for a second, if someone records a public official or person of power abusing their power (think cop beating/shooting), then without being part of "official" block chains one could simply deny the accusations as fake news. This takes some of the only power left from the people (at least in the States anyway). While I'm not saying let's not try to tackle the barrage of fake news, we should at the very least ask ourselves are there concerns outlined above, and the many more I'm sure that aren't listed, worth ignoring for the desired outcome. A possible, more long term, solution might be to teach people to think critically again, but I'm afraid the intelligence curves are starting to skew more to the left than right in terms of ranked measures of intelligence recently.

    • Quantum computing is not magic. It can speed up some encryption math, like factoring large numbers, but it's no good for solving bit-shuffling hashes.

      Also, hashing and encryption is not a static target. If technology gets to a point where some methods can be broken in reasonable time, we can upgrade them to different algorithms, and/or longer keys.

    • You can't already have the data immutability property outside Bitcoin. Because Bitcoin is the only genuinely decentralized cryptocurrency. You don't even need a quantum computer to undermine the utility of the whole system.

    You can't solve a social issue with a technical solution. Fake news is much more of a product of editors choosing what aspects of a story to report than it is of wholly fabricated stories. Refusing to report a story at all is also an incredibly powerful way to manipulate the public discourse.

    The real issue with the news is editors selectively editing the news to support the bias of their personal narrative. Adding blockchain to a story that has been been selectively edited to manipulate the bias of the editors narrative to begin with isn't going to fix anything. All things considered I'm inclined to think that the vast majority of fake news likely started as real news.

    The problems comes down to defining fake news. Is news fake when it is blatantly false or is it fake when it is factually accurate but presented out of context? By presenting things out of context you can claim to be telling the truth when you are in fact giving people fake news. Technology isn't going to fix that.

    • Fake News isn't when an editor adds spin to a story. Bernie Sanders not getting mentioned in a story about a poll when he's at first place in that poll isn't fake news, it's spin. Sometimes called a "Narrative".

      It's not hard at all to define fake news. It's stories presented as news that are patently false, either for the propaganda purposes, to sow distrust in a population or to generate advertisement dollars from users clicking through to read the stories.

      "Pizzagate" [wikipedia.org] is the most commonly known ex
      • A lie is a lie. A lie by omission is in some ways worse than a flat out fabrication because it is harder to dispute the spin. That's the point of half lies. You can never be called out because everything you said was still true. In court the prosecutor is legally required to provide any exculpatory evidence they have to the defense. Same thing with news. Spin is just another word for lying.
      • When a news story is presented to support a narrative and withholds the context that would change that narrative it becomes propaganda. By manipulating the facts that are presented and failing to present context you are converting real news into fake news. This is literally the creation of propaganda. The result of this kind of thing happening again and again is that people simply no longer trust the news media.

  • Can blockchain be applied to stop blockchain hype?

  • Maybe, just maybe...

    1) Do not allow any single source of information to form your opinion on any actual subject

    2) Read news, not only headlines and first couple paragraphs. If you really care, research at least a bit on your own.

    3) Make your own personal rating of authors/sources. In future, more trusted sources can help you speed up step 2.

    4) Always question what news says, try to learn more. Cui bono, why now, etc...

    The problem is that the term "Fake News" has been redefined multiple times, and now it has come to mean anything that a subject happens to disagree with. There are many different kinds of fake news, and in order for technology to address it, like this story about blockchain authentication, they have to be much more specific about which kind of fake news they are trying to prevent.

    "Fake news" now includes portraying news from an angle that some subject feels is not totally representative of their viewpoint. Thus, nearly any piece of news concerning politics or government is now considered "fake news" since you can find individuals that disagree with the exact interpretation or meaning of that news. At least a part of this is based on the fact that most all news organizations now have a political viewpoint and agenda, so there is some kernel of truth to many people believing most news is fake news. There is no technical solution to this.

    In social media a few years ago (and perhaps it is still ongoing, but I haven't noticed it personally) there was a rash of truly fake news. These were propagated by fake news websites, which would take some actual news story and rewrite it to apply to many other towns. They would have a different URL for each place, but the news story would be the same (with just the different city / locale name changed). In social media these stories would spread like wildfire, because they had very sensational headlines like "Townsville Mother Drowns her 3 Children", where "Townsville" is replaced by multiple different locations depending on the URL. Again, these were usually based on an actual news story that had happened in the past in some other location. The entire point of this was to install malware apps, install new email providers on their phone to spam them with, etc.

    Another type of "fake news" is where countries like Russia are seeding a target country's social media platforms with inflammatory content. Oftentimes the news is true, but is heavily skewed to the left or right to try and get that base upset and angry. This type of thing has been going on since the advent of broadcast radio, where state-sponsored radio stations broadcast news that they want people to hear to further their cause. Many countries still do this today with shortwave radio news broadcasts.

    When it comes to the true fake news, the problem is social media. People are stupid when it comes to resharing things. I regularly see things shared on Facebook that were true news, like an abducted child, and when the actual article is opened you find that it happened a long time ago and the child was found safe. I see people in my own town sharing missing child alerts, and when the article is actually opened you see it applies to an entirely different country. The person couldn't even be bothered to look at the link before they shared it.

    This is primarily the fault of Facebook, Twitter, and other platforms, in that they have made it too easy and without any consequence to share things. This is particularly true for sharing URLs to content not even on the platform. When an external link is first shared, Facebook will scrape it at that moment and retrieve text and an image, if there is one. Now, when that item is reshared, no matter if the content at the URL has been updated, the shared content will be static and won't change. That is out of necessity, since the content could be changed after a person shares it to represent something they did not want to share (they shared "I like cats!" but then the content was changed to "I hate cats!" after they shared it). However, this propagates inaccurate or out of date information because the share never updates to reflect the current state ("the missing child has been found!"), which would prevent the item for being reshared again and again (since people can't be bother to actually view or vet what they share).

    Truly, all this mess is the result of social media and people generally acting like they don't have any common sense when i
