Meta Builds Tool To Stop the Spread of 'Revenge Porn' (nbcnews.com) 94

Facebook's parent company, Meta, has worked with the U.K.-based nonprofit Revenge Porn Helpline to build a tool that lets people prevent their intimate images from being uploaded to Facebook, Instagram and other participating platforms without their consent. From a report: The tool, which builds on a pilot program Facebook started in Australia in 2017, launched Thursday. It allows people who are worried that their intimate photos or videos have been or could be shared online, for example by disgruntled ex-partners, to submit the images to a central, global website called StopNCII.org, which stands for "Stop Non-Consensual Intimate Images."

"It's a massive step forward," said Sophie Mortimer, the helpline's manager. "The key for me is about putting this control over content back into the hands of people directly affected by this issue so they are not just left at the whims of a perpetrator threatening to share it." Karuna Nain, Meta's director of global safety policy, said the company had shifted its approach to use an independent website to make it easier for other companies to use the system and to reduce the burden on the victims of image-based abuse to report content to "each and every platform." During the submission process, StopNCII.org gets consent and asks people to confirm that they are in an image. People can select material on their devices, including manipulated images, that depict them nude or nearly nude. The photos or the videos will then be converted into unique digital fingerprints known as "hashes," which will be passed on to participating companies, starting with Facebook and Instagram.

        I was thinking, if someone wanted to really invest into it, perhaps they just get pics of the person, and use what is becoming more freely usable and available Deepfake software and then, they could just churn out an almost never ending stream of revenge pr0n, with different situations, different acts and locations, etc.

        Would it not be hard for this system they're talking about to track it?

      Back when I was a teen before Home Internet was a thing, When I was alone, I use to switch to the scrambled adult channel, in which a boob may be visible for a fraction of a second.

      But today where Porn is a quick search away, why would anyone deal with a heavily altered picture where they have access to more porn than they can safely deal with.

      While I am sure some people will get off on seeing someone they know, but if it is so doctored up, what is going to be the point.

    • They claim that they can identify deep fakes, so it sounds like they have a failsafe of:

      IF FacialRecognition($Image) == $Person && IsNSFW($Image)
      THEN BLOCK()

      Also image hashing of distorted and warped or reflected images is getting really good. Lots of strategies like breaking down small blocks and looking at something like the FFT decomposition rather than pixel matching and numerous other far more sophisticated strategies.

    • You submit your images to them and they will ensure they wont get posted. What could possibly go wrong, I am guessing their database of images will be dumped only in 2 years.

        • Because conspiracy theories are pointless, and with data privacy laws these days having actual teeth in many parts of the world the idea that a company would be as mind bogglingly stupid to do that is quite far fetched.

          Facebook is actually quite reliable. They have always done what they said. What they have said has been terrifying, but that's no reason to believe they suddenly would not do what they say.

    • Holy Heck...I came here to say the same thing.

      What could possibly go wrong when you have a website who's sole purpose is to collect intimate/explicit images from the whole world. At least when Target gets breached all I lose is a credit card number. When this place gets hacked it's going to be a mess.

      Supposedly it doesn't store any copies of those images but only generates a hash...until we find out that someone was sloppy in the code and oops it does store a jpeg in the cache or something.

      Easy solution: How about just not taking sexually explicit images in the first place. It won't stop the secret filming, but I'm guessing 80-90% of the pics and vids are consensual.

      The whole idea is a complete non-starter, regardless of which way you go.

      Put the fingerprinting tool online? We have no guarantees images will be properly protected. Most of us have heard stories about TSA agents taking cell phone pics of scanner images of well endowed people, "Geek Squad" types scouring computers for nude pics, hospital workers looking up the medical records of celebrities in the hospital's care, or other instances of people abusing access.

      Give us a local fingerprinting tool? The services have no way of verifying that the images are valid. Trolls or people with a bone to pick could generate fingerprints for every frame of every movie, every picture their ex has ever posted to Facebook, or the logos for every company they dislike, effectively erasing their targets from Facebook.

      The CSAM (read: child porn) databases operated by organizations like the National Center for Missing and Exploited Children "work" because the images are already in the wild when they are collected, meaning the damage is already done and the images are verifiable. Unfortunately, all they can do is work to prevent additional harm after harm has already been done.

Of course once you find the image of you then upload it, but then whats stopping someone uploading every image to the site.

      It doesn't need to be hacked. It just needs to have a bunch of "non-NCII" images uploaded to it to the extent that its ability to properly function is completely ruined. Given that we have GANs that can generate limitless quantities of such material, it's a sure bet that this will occur.

  • If you dont want your nudes flying over the internet just send them to this central repo of nudes owned by a company you can trust with your intimate data xD yeah right...

      Too simple?..not sure...it's definitely a stupid one. If you're asexual, cool, you do you. Many of us like to be sexually aroused. We like to sexually arouse our partners and especially receive sexually explicit images from them. Most assume their husbands won't share the images. Also, many of them were shared without anyone's consent...a simple device leak or cloud provider, not necessarily a disgruntled partner.

      People are going to take dirty pics. It's a lot of fun. It's stupid and judgmental to shame people for doing so, which you're definitely doing.

      On a similar note, I hate weed. I don't like getting high. However, some do. It's their right. I don't want them getting fucking poisoned by the dispensary. Just because someone engages in activity that doesn't do it for me, doesn't mean I am indifferent to harm that befalls them. Same thing with gun owners. I don't enjoy shooting guns enough any more to own one. It's not for me. Regardless, I don't wish harm on responsible gun owners exercising their 2nd amendment rights.

      Yup, never taking pics decreases the chances of them getting shared. It doesn't eliminate threats from hidden cameras, peeping toms and such. However, by your logic, the AIDS crisis could have been stopped if people just never had sex. It's dumb. People are going to fuck. People are going to get high. People are going to shoot guns for fun. People are going to take naked pics. It may not be what you're into, but you don't need to be so judgmental. It's kind of a dick comment. Slut shaming is a shitty thing to do. Why do you want to discourage women from sharing pics of their bodies?

      • It's more of an extension of the old saying, "don't post anything on the internet that you don't want there forever".

        So, extending that, don't risk yourself by letting compromising images to be taken of you, because sure as shit there is ALWAYS going to be a risk that it will end up on the internet.

        You don't eliminate all risk of course, but that's the same with your AIDS analogy.

        Of course people will have sex and do drugs, but you can lower the chance of catching or passing on aids by not sharing needle

          Take a step back and consider that sharing intimate pics without consent is a CRIME. You're telling crime victims they should have listened to your grandma, roughly speaking. You're indirectly slut shaming them.

  • Of all the things Facebook finds problematic, thank the heavens they are investing in figuring out how to find and delete revenge porn.

  • Uploading the images you do not want shared to a central repository seems like something that no one in their right mind would do. It also implies that all parties have a copy of the image they can upload. FB has decent facial recognition and AI experience. How feasible would it be for them to detect potential explicit images, match the faces to their user base, and ask the users if they are OK with the image being uploaded by third party?

      • Then this increases the chances of false positives. It's highly doubtful that their 'AI' is sophisticated enough to analyze an image, and be able to compare it to another same enough to a human image and make a 100% correct guess every time.

        I wouldn't be at all surprised if it does no more than spot sampling, to save on processing on a system that is recieving thousands of still image files every *second* (nevermind videos). This guarantees that unrelated images will 'collide' with what's in the database.
