This new protection system works similar to the anti-child-porn detection systems in use at Facebook, and other social media giants like Google, Twitter, Instagram, and others.
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. Potential victims will need to upload nude photos of themselves
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.
This is possible because in April this year, Facebook modified its image reporting process to take into account images showing "revenge porn" acts.
Facebook says it's not storing a copy of the photo, but only computing the file's hash and adding it to its database of revenge porn imagery.
Victims who fear that former or current partners may upload a nude photo online can pro-actively take this step to block the image from ever being uploaded on Facebook and shared among friends.
We won't be doing this. I don't even want to see hashes of you folks naked.

The social media giant recently announced its new plan to combat "revenge porn," when individuals post nude photos online without the consent of the subject." http://www.foxnews.com/tech/2017/11/08/facebook-says-it-needs-your-explicit-photos-to-combat-revenge-porn.html

The problem with that is that by definition revenge porn is posted by somebody other than the target. So, if the target doesn't have a FB account, it just means fewer "friends" see it. But strangers might see it and most people have friends that are on FB, so those people can see as well.

If I suspected that I were a victim of revenge porn, I'd browse /b/ before I'd browse Facebook.
Also, I have an old story I posted on Slashdot and may have posted here. Pardon if I already posted it here. Anyway, when I was a freshman in high school, a disgruntled ex-boyfriend of a 16 year old student went through the trouble to enlarge a photo of his ex girlfriend topless (including face) and run off a shit-ton of copies of it, then at night spread those "leaflets" all over the campus. They were everywhere - tucked in tree branches, hidden under trash cans, stuffed into mailboxes, and generally all over the ground everywhere. The administration and other staff were still finding and picking up copies well into the afternoon after an all-day effort.
No cops were called, there were no mentions of "child porn." This was back in the day when anything with a set of tits wasn't considered "child porn."
