Facebook to Fight Revenge Porn by Letting Potential Victims Upload Nudes in Advance

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.
