Using that to combat paedophiles too are they?

actually yes. google drive has the biggest Child pr0n databse outside the us govt

Emmmm... ok

In a world run by satanic paedophile madmen (internet chatter) FB and the U.S gov have the biggest collection of CP?

For online security and safety?

I can see this ending well...

Not.

Not being even remotely familiar with what goes on on facebook, I don't do facebook...

Is revenge porn a thing? ...and how does pre-emptive nudes help? I'll admit to being somewhat confused.

I'm just saying you can't then turn around and be mad when your private stuff finds it way on to Xhamster or some other site by a jilted lover or a random hack.

idk... if i carry money on me and i get mugged, i can be mad about that, right? :p

The better comparison is if you are flashing a wad of cash around and showing off in a bad neighborhood you can't really be mad if you get mugged.

I keep sending nude photo's and still. . . no one will post them.

Building a porn database under the guise of anti-revenge porn?

They might as well hurry up & change their name to Fapbook and get it over with.

I can't see this taking off because nobody is going to take Facebook at its word that it's not secretly storing images but it's actually a novel approach. Perhaps what's needed is an app that can be used to generate hashes locally? Then the users would simply upload the hash.

In fact, you'd then have something that could be used for multiple social media platforms without potentially compromising the users' privacy.

I'm not that good at image processing, but I don't think this works. The problem is that once you generate a hash it's supposed to be difficult to recreate the original file. If you were comparing two copies of the same image this would work, but instead you're trying to leverage image recognition which relies on information in the original file in order to find similarities. Hashes shouldn't be comparable at all between two similar but still different files, therefore simply comparing hashes won't work.

What I would do instead is built a facial recognition platform that censors a persons face if the photo also detects nudity. That works for full body images, where a person is recognizable. You could then either blur faces or block the upload entirely.

That doesn't completely stop the concept of revenge porn, but it does eliminate the proof that a photo is of a specific person.

Wouldn't slightly altering the file change the generated hash? It would need to be an identical copy of the picture. All you'd need to do is resize it or something to beat their system. This fairly useless as well as just being utterly stupid.

And now we wait for a few months for facebook to start it's new revenge porn website.

Yes. Comparing hashes won't work. You actually have to identify images. The only algorithm I'm familiar with for this (because it's the only one I've used for computer vision) is Hu numbers. Those don't work with a hash. I'm pretty sure that no algorithm will work with a hash because in order to compare similarity you need to compare the raw files. When a hash is working correctly changing a single bit in the file will drastically alter the hash.

Same for videos?

Yes. Videos are just a bunch of image files strung together with an audio track attached.

99% of people are idiots... or they don't mind eventually sharing their goods with guys fapping.

Look, I don't really care what people do in their bedrooms. If taking pictures and videos turns them on, then more power to them. I'm just saying you can't then turn around and be mad when your private stuff finds it way on to Xhamster or some other site by a jilted lover or a random hack.

I disagree. This goes into uncharted legal territory over who owns the digital likeness of someone, but I take the idea that if it's yours physically, it should be yours digitally. That means that if we have a reasonable expectation in public that our likeness won't be stolen and used for someone elses motives, then we should be able to expect the same thing digitally. That in turn means that a person should own their digital likeness, which therefore means there should be content distribution systems that give the owner control over their likeness. They shouldn't be forced to not participate just because of what malicious individuals will do.

The bottom line is, that means security.

What I see happening in the coming years, especially with cloud storage becoming the default, is that images will be licensed, and eventually an individual will have access control over all images bearing their likeness for sharing purposes, with the ability to copy and save the image locally disabled.

There's still several hurdles to clear before that happens, but I think we'll be there within 15 years.

Not a facebook user either, I don't know what people share on that platform specifically but revenge porn is huge.

Like I said above though, I don't think a nude database is needed here. I'm not even sure if it would increase security due to the risk of unauthorized access to servers/accounts. I do however think running a facial recognition database... which Facebook already has (and I believe the government should make theirs available to corporations for this use) past another system which looks for nudity in the photo and then either denying the photo unless all involved approve it (and only until someone doesn't approve), or blurring all faces would be a reasonable approach.
