Facebook to Fight Revenge Porn by Letting Potential Victims Upload Nudes in Advance
Submitted via IRC for TheMightyBuzzard
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.
Facebook asks Australians to send nude photos, for safety
"Worried that an ex-boyfriend or girlfriend might post your intimate photos on the internet? Facebook says it has a solution – as long as you'll hand over the photos first.
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

There are so many problems with this, you really have to wonder: which PHB actually approved it? Let's see:
- You have no idea which photos your ex might upload, so you have to upload lots more just to be sure.
- If you took video, are you supposed to upload each frame individually?
- Anyway, you don't have the photos or videos that your ex took on their phone, so it's not going to help anyway.
- Meanwhile, some random strangers are looking at your pics.
- If you're attractive, there is a non-zero chance that your pics will be copied, shared, and even uploaded to a porn site.
On the positive side, this may help a few people realize just how totally creepy Facebook really is...
Everyone is somebody else's weirdo.

Sounds more like a PFY scheme to me. Get all your users to send you nudie pics which you can then blackmail them with.
My rights don't end where your fear begins.

As someone who maintains various mail systems, they are already doing this.

And, if ex applies a filter or, say, changes Green value in pixel 523097 from 180 to 179, the hash should change.
Hard to believe Facebook engineers are really this naive? Maybe it's a social experiment, just to demo how gullible people are?

See earlier post about TinEye.com it matches images with a number of "defects" like this, works with different cropping and with photoshopped mods.
