Facebook To Fight Revenge Porn by Letting Potential Victims Upload Nudes in Advance (bleepingcomputer.com)
Catalin Cimpanu, writing for BleepingComputer: Facebook is testing new technology that is designed to help victims of revenge porn acts. It works on a database of file hashes, a cryptographic signature computed for each file. Facebook says that once an abuser tries to upload an image marked as "revenge porn" in its database, its system will block the upload process. This will work for images shared on the main Facebook service, but also for images shared privately via Messenger, Facebook's IM app. The weird thing is that in order to build a database of "revenge porn" file hashes, Facebook will rely on potential victims uploading a copy of the nude photo in advance. This process involves the victim sending a copy of the nude photo to his own account, via Facebook Messenger. This implies uploading a copy of the nude photo on Facebook Messenger, the very same act the victim is trying to prevent. The victim can then report the photo to Facebook, which will create a hash of the image that the social network will use to block further uploads of the same photo.
They should allow the potential victim to upload the hash, and not the image.
I know they "claim" they will not keep the pictures, but only a hash of the image. But do you really trust Facebook that much?
Won't take long before the police will pay Facebook to ID the corpses they find.

I have a QUICK solution to all this, works 100%.
Don't fucking let someone take pictures or video of you naked and/or having sex!!!!
Sheesh....when did something like common sense about not letting someone take pics of you in compromising situations go out the fucking door?
Yes, I suppose that's a reasonable solution, if you never want to receive sexy pictures or video from a significant other. As most people would like to receive such, then blaming the victim and discouraging the practice would seem to be counter to most folk's interests. But not yours, I guess.
We just saw an article related to this. The hash is something like Microsoft's image identifier hash they acquired when they bought... ???...
It basically works like this.
Image is resized to a standard size 1020x768 I think
converted to black and white
edge detect applied
at this point Trained AI is supposed to be quite accurate in identifying matching photos
this works even if you resize the photo or color adjust it
Seems like there will be gaping holes to be discovered in this method though.
Problem isn't the victim considering them compromising. The problem is the victim's family, friends, coworkers, boss, etc considering them compromising.
Really though, its a generational thing to some extent. By the time the children of the millennials are in their 40s or 50s and running the world, so many of them will have nudes, stupid social media posts, etc out in the world that its going to necessarily be a non-issue or for examples employers won't be able to find any employees that fit their "internet purity" conditions.
Its only a problem right now when the generation doing the hiring never really had to deal with these kind of things while the generation looking to be hired don't really care that much because everyone they know does it. Its the intersection of those two worlds where everything hits the fan.. well, in a generalized sense of course -- there will always be exceptions obviously.
