Facebook is using nude photos to prevent the spread of nude photos

You send the nude to yourself in Messenger, and Facebook creates a hashed digital fingerprint of the photo - an encrypted version of the raw data in the image file. The image can then be deleted, but Facebook will be able to prevent any further uploads of an image with the same digital signature.

As per a report in the Australia Broadcasting Corp, it is partnering with an Australian government agency to prevent such image-based abuses.

If there is a photo or video out there you are anxious will be shared without your consent, Australians can contact the e-Safety commissioner.

So, just in case a person's former lover decides to leak any of those pictures, one can take steps to prevent the images from being shared widely on Facebook or Instagram. Wink tipped, so to speak, Facebook will create the hash for each image without storing the pic itself, and definitely not using it to start some sort of dinkle gallery channel on Sky. The Telegraph reported that to provide the photos directly to Facebook, users should send them through the Messenger app. Digital forensics expert Lesley Carhart told Motherboard that even though Facebook say they won't keep the original images, totally and irrevocably deleting things is much, much easier said than done, leaving a chance that the original pictures you upload could be recovered or accessed.

In April, Facebook announced an algorithm that uses one sample photo to identify similar photos and remove them from the social media platform. Australia's safety commish Julie Inman Grant defended the experiment, arguing "they're not storing the image".

Facebook's customer support team will then review a blurred version of the image to ensure it's explicit, then "hash" it before deletion.

By the way, "revenge porn" is a horrendous phrase.

Earlier this year, Facebook implemented a photo-matching tool in the U.S. to stop sharing of content tagged as revenge porn in the past.

"Australia is 1 of 4 countries participating in a pilot with Facebook to help prevent sharing of intimate images".

As of September previous year, more than 200 people in the United Kingdom had been prosecuted following the introduction of a revenge porn law in 2015.

This builds on existing tools Facebook has to deal with revenge porn.
