back to article Facebook's send-us-your-nudes service is coming to UK, America

Facebook has begun conducting a pilot where it solicits intimate photographs of women – and it will soon offer the service in the United Kingdom as well as the US. Anxious exes who fear their former partner is set on revenge porn will be urged to upload photographs of themselves nude. A hash of the nude image is created and …

        If they're saying it's completely automated then they carry the same risk even when you upload for hashing (could you, for instance, upload a bunch of Trump images?).

        Re: Why...

        That's no excuse. They could easily do that check at the point they find a clash. The whole point of this nonsense is that they're supposed to be detecting when another matching image is uploaded in the clear.

        Either way, you can try uploading someone else's photo and, either way, at the point they're considering removing it they'll be able to see it. The difference is that if you hash it yourself on your own machine, they can't see it if nobody uploads it in the clear.

        I cannot believe that this protocol is being seriously suggested as a way of protecting people's privacy.

      Re: Why...

      Doubt that would work, since you could just change one pixel and the hash would change. Meaning you could have 2,000 separate hashes for the same image.

      For example, services that flag child pornography when it's uploaded use a special software (PhotoDNA) which converts the image to grayscale, then breaks it down into a grid and calculates a number per grid until they wind up with something like 1000,481,0,0,251..., meaning that modifying the image is pointless.

      People would be better off getting the numerical sum of their nudes with that.

      But the problem with that is, regular people aren't allowed access to that software unless they're a LEA or popular service like Facebook. (Which sucks, as I have a large anime artwork collection I'd love to sort through far more easily to remove duplicates.)

            It is not illegal in England & Wales jurisdictions. Any police action against a naturist is usually deemed "Public Order". You are apparently responsible if a neighbour threatens you with violence because of their own "dirty" thoughts.

            The ripped jeans etc are examples where how women behave perfectly normally is deemed by some to be "asking for it". See example in Egypt recently.

              I share the opinion that there's nothing innately shameful about the naked human body. Unfortunately a significant proportion of the populace think otherwise, and our legal system often tends towards the puritanical. If you have a naked picture leaked onto the internet you get to choose whether to brazen it out, or to accept the shaming that other members of society will inevitably try to fling your way - those are pretty much the only options.

              Advising people not to allow naked pictures to be taken of them therefore isn't victim blaming, it's just good advice. The reality is that once there is a picture of you naked it's very easy to lose control over where that image ends up (whether that's by a "friend" leaking the image online, or a hacker exfiltrating the images). If you're OK taking that risk then go ahead - as long as you're an adult making an informed choice about it.

                There isn't anything wrong with the naked human form. But I don't want pictures of my naked body circulating on the Internet, so I don't let anyone photograph me naked and I don't take any photos myself.

                If other people want to make photos/films of themselves naked or having sex, that is their business, but it should be clear to them upfront, that those images might end up on the Internet. If they don't want those images plastered all over the 'Net for the rest of eternity, they should think twice before letting those photos/films be made...

                Peephole cameras is something else, but you probably don't have them to upload to Faceplant in the first place. And, as others have said, hashing locally and uploading just the hash makes a lot more sense, although it will deprive the pervs at Faceplant of their jollies.

      I came to say something similar.

      Until the person (male or female) has had those naked photos displayed/shown to people/uploaded without their consent, they are not a "victim" of anything.

      They are a person of whom a naked photograph exists. not a victim of anything at all.

      While i'm 100% against such things, the language used here is odd. You can't preemptively "be a victim". You're not a victim unless the naughty photos (which are normally taken WITH consent) are then shared minus the consent.

      It's not a simple filehash.

      We've had TinEye - capable of taking an input image and finding cropped variations across the net - for years and years. It's developed in the meantime, but this is far from new technology.

      The hashing is based (AIUI) on the variation between pixels in "key" locations (of which there are more than a few), so cropping the image won't help. Even contrast tweaks have to be fairly extreme to throw it off.

      All that said, it's far from perfect.

      It used to happen, but amateur nude photography was a minority hobby, at least among those without their own darkroom.

      When I was a student, one year I had a summer vacation job in the Kodak (NZ) slide mounting room. Since it was illegal to send nude pics through the post, Kodak had to pull any boxes of slides containing them and forward the box to the snapper's local cop shop for collection.

      This meant that those running the slide mounting machines were expected to spot any such photos and check them in a slide projector. Cue a yell of 'Got one!' and a general stampede in the direction of the projector and screen when anything was found.

      However during that summer break (6 or 8 weeks - I forget which) I only remember that happening two or three times on my shift.

      Would you have to send a copy of your passport - and hope Google doesn't hash that one by mistake.

      shame I can only upvote once.

      This, this this.

      If I have a naked photo of my wife, and we become "no longer married" and decide to use it in such a way, who has that photo?

      Me of course, it's on my phone, isn't it!

        Again, a little common sense goes a long way.

        Of course in the situation you describe it doesn't help..

        But in other scenarios it does, so for example if a partner sends me a picture of their bits and we later split up I cannot then upload that picture.

        Given that it's fairly common to exchange nudes nowadays it's certainly useful.

        If you upload it to t'internet and she sees it there, she now has a copy of it, to send to Zuck.

      Re: Another wee problemette...

      FB could only use the uploaded nude as an authorization token (face-checked against existing tagged photos or some such) to block all nudes tagged with your profile name on other profiles. After the outcry, version 2 would then give you the opportunity to allow select profiles to post nudes of you again.

    Anyone used Googles "image matching" ?

    just saying ?

    1. Mage Silver badge

      Re: Anyone used Googles "image matching" ?

      I have.

      It has a huge number of false matches, but does most times allow me to manually find the artist of a well known cropped painting. Amazing though how often the sites higher in ranking have wrong attribution of artist or that Google offers matches that are not remotely similar.

      It can be very poor on logos, which is odd.

      It's rubbish if the image isn't on many web sites.

    Hash?

    So, the sender edits the image, and tweaks the value of one pixel off in the corner, and now the hash is completely different, which completely defeats the system. That's how hashes work. This has to be one of the dumbest ideas I've ever heard of. Oh, wait, maybe not the dumbest, if some guy is wanting a bunch of nudes sent to him.

      Re: Hash?

      Or maybe (as others are suggesting), "hash" is just sloppy shorthand for what would actually be some kind of image recognition function? I gather Google has quite a good implementation?

      That said, I've never really played with image recognition myself until recently. I have been trying it out using digiKam against my home photos. Not impressed so far - it has quite a lot of false positives just when trying to recognise what constitutes a "face" (even when I turn the "accuracy" right up), and one of the first tests I gave it - some shots of a railway station taken from the bridge, please find similar photos - it failed spectacularly, completely missing even near-identical shots in the same folder.

      Anybody have any hints?

      Re: Hash?

      It's not just a hash of the file. According to the article in ahem the guardian which has significantly more information than this article, it does use Photo DNA whose ' “hash” matching technology made it possible to identify known illegal images even if someone had altered them'

      At least soon facebook will have all of the 'necessary hashtags'.

      To satisfy my curiosity, I succeeded in changing the hash value of an image I downloaded from a website merely by opening and then saving it with an image editor. I didn't have to modify any pixels at all.

      This whole proposition seems like a bizarre social experiment dreamed up by Facebook's BOFH to determine the depth of the userbase's "Peak Stupidity".

        That won't affect the software they're using.

        If you're patient enough to try it, get the original indexed by TinEye.

        Then reverse search your "modified" one. Then crop it and try again, then change some pixels and try again.

        You will most likely find that TinEye correctly returns the original every time. When they say hashing, they don't mean filehashes.

    Uploading another person's intimate pictures seems not unknown amongst teenagers - either out of spite or stupidity. Are all the teenagers going to pre-emptively have their own pictures hashed - just in case they "escape" though someone else?

    Would that make Facebook guilty of handling such apparently under-age pictures? Would Facebook report the owner to the police? Apparently such digital selfies are still illegal - especially if transferred over a network.

    This will surely only work if the person in the photos has a copy of the photos to upload to create the hashes and that the posting the 'revenge porn' does not alter images in any way.

    Even sophisticated filtering software can be by passed by rotating the image through a few degrees, altering the contrast/brightness or cropping then adding a patterned border etc.

    This sounds more like a PR campaign than something that is really going to stop a person determined to cause someone distress by upload images.

    Photo DNA cannot be as reliable as they boast

    It's an educated guess, because I don't claim inside knowledge.

    But I reach that conclusion on the basis that they're not making it freely available for home use. To be fair, it doesn't look like Microsoft have anything but honorable motives on this occasion (although I would question their own security - if the FBI comes calling are they in a position NOT to release such images?) (one of the many questions Facebook will also have to answer)

    They make the software available in various cloud offerings and have donated it to a Missing Child charity amongst others. So why aren't they simply allowing us all to download a copy and do our own hashing and upload the results instead of the image - as suggested in the first post on this thread (John Robson)

    I can think of only two possible explanations. First is that the process is so power hungry, you'd need a Bitcoin mining rig to run it. That doesn't look feasible from what I've read about the process. Looks like it might take about as long as creating a couple of thousand hashes. Under a second on most desktops.

    The second is that they don't want it in our sticky little hands because it would relatively trivial to find ways to modify target images in such a way that they wouldn't be detected, so to preserve the value of the service, they don't want the great unwashed to access it.

    In short, they're relying on "Security Through Obscurity" and, like most such attempts, that'll work for a few months, until the obscurity is cracked...

    Oh, and by the way, the (partial )solution to sharing intimate private images is sharing one time keys which BOTH/ALL parties have to re-combine to access the images/data (as outlined in Digital Telepathy)

    Limited use case?

    So if you happen to have access to photo(s) of you, which you believe are also in the possession of an ex/other (why would *you* have copies?), and if there are few enough of them to make this upload practical, and if Facebook doesn't set too low a limit on the uploaded quantity for any one customer, and if you trust Facebook to permanently delete the copies you send, and if you're willing to have total strangers in the form of FB employees vetting what you send (because it simply *cannot* be a fully automated process, for reasons that surely don't need to be belaboured), and if legalistics don't require FB to be able to retrieve all images anyway (think: kiddie porn), and if you trust the security and integrity of ANY internet company (cue hysterical laughter), then it's likely that if your ex does try to mischievously upload embarrassing photos to FB—they won't be able to.

    Except of course, such photos probably violate FB's ToS anyway, so the miscreants will have uploaded them somewhere else where that entire fraught, unreliable and not to be trusted process wouldn't help in the slightest. Because, lest we forget, Facebook is not the internet. It's just the shallow end.¹

    What does FB sell?

    Facebook sells information about it's users that they have been more than happy to submit in various forms. FB and other companies collate that information with information they acquire from other sources. What would keep them from matching up nude photos with individuals using facial recognition/body recognition? You don't even have to have an account if some horrible person you thought of as a friend posted a picture of you and tagged it with your name. FB has a nasty habit of turning private things public without notice and even sometimes by accident. They might even "accidentally" make the nude photos available to their customers (not users, people that give them money for user information) due to a misconfigured flag or something. After noticing that bandwidth is off the hook, they might plug the leak, but the valley below will already be flooded.
