Facebook is asking Uk users to send nude photos of themselves to the social network, to try to stop revenge porn.
If you are worried about an intimate picture of you may be shared by someone else, the idea is to get locked before it appears online.
A similar technology is used to try to stop the spread of child abuse images.
Facebook has been testing the system in Australia, and is extending the trial version for the UK, USA and Canada.
A spokesperson told Newsbeat the idea is open to people in the UK now.
Revenge Porn: What to do if you’re a victim
Facebook has not revealed any detail about how the evidence in Australia is gone – but, of course, the idea requires a huge leap of faith.
Please send sexually explicit photos of themselves to Facebook?
You may be sure the image should be managed in a sensitive way – and most importantly, not shared?How it works
If there is an image that you’re worried about it, Facebook says that you should contact the partner to the test. In the UNITED kingdom, is the Revenge Porn Helpline.
We will then get in contact with Facebook and have sent a link to upload the photo.
Who will see my naked photos?
Facebook is the Global head of Security, Antigone, Davis has told Newsbeat that the photos can be viewed only by a very small group of about five specially-trained auditors”.
I will give the photos a unique digital fingerprint – something that is called a hash.
The code will then be stored in a database. If someone tries to upload the same photos, the code will be recognized and will be blocked before it appears on Facebook, Instagram, and Messenger.
The original photos will not be stored.
Will be the idea will definitely work?
Antigone Davis admits that there is no “100% guarantee when it comes to photo-matching technology”.
This is because it is possible to manipulate the images in such a way that you are different from the original. But she says they are getting better and better.
This system only works if it is actually the image that you are concerned about.
If, for example, your ex took a load of photos on your phone and you don’t have them, this idea does not help.
The UNITED kingdom, the Revenge Porn Helpline has seen enormous year-on-year increases in reported incidents since it was launched in 2015.
The hotline received more than 500 reports in 2015 and more than 1,000 in 2017.
