Grant sought to allay concerns of users about what Facebook would do with the photos they upload.
Australia is one of four countries taking part in this pilot project, Facebook's head of global security, Antigone Davis told ABC.
When you send your nude photo to Facebook, what exactly happens to it?
It works like this: you send Facebook your nudes, the company's software has a look and then image matching algorithms will continuously comb the site to make sure that no images matching your nudes are posted.
The plan is that Facebook will hash the images, encoding them with a unique identifier.
In other words, if an image has been taken down and someone tries to re-post or re-share it on Facebook, Instagram or Messenger, the person will see a pop-up that says the photo violates Facebook's policies, according to Tech Crunch.
Facebook won't store the image, just the digital fingerprint. There is also no guarantee the next Facebook or Messenger hack won't reveal the nude images itself.
Suns finalizing deal to send Eric Bledsoe to the Bucks
A tweet that Bledsoe tried to say was in regards to being at a hair salon , but apparently the league didn't buy that excuse. Bledsoe's trade is timely since the Bucks are in a slump, losing their last three games to drop to 4-5 on the season.
Facebook is partnering with a Australian government agency to prevent such image-based abuses, the Australia Broadcasting Corp reported.
"I literally recover deleted images from computer systems all day - off disk and out of system memory".
The program would then prevent another user from uploading the same photo.
Australia's e-Safety Commissioner Julie Inman Grant said Facebook is not storing the images, but only a digital footprint of them.
Carrie Goldberg, a New York-based lawyer who specializes in sexual privacy, told the Guardian she is "delighted" with the initiative and thinks it can help fight revenge porn.
So how does allowing Facebook to see you naked prevent the rest of the world from seeing it? Roughly four percent of US internet users have been victims of revenge porn, according to a 2016 Data & Society Research Institute report.
Earlier this year, Facebook implemented a photo-matching tool in the USA to stop sharing of content tagged as revenge porn in the past. If Facebook has the photos, it can specifically recognize and instantly block them if they turn up elsewhere on Facebook, Messenger, or even Instagram.
