Facebookhat a plan against so-called revenge pornography, and it goes like this: send all nude pictures to your (ex) partners of yours and who should never see anyone else, simply on Facebook.
if ( typeof AdController !== ‘undefined’ !window.Zeit.isMobileView()) { if ( !document.getElementById( ‘iqadtile8’ ) ) { var elem = document.createElement( ‘div’ ); elem.id = ‘iqadtile8’; elem.className = “ad ad-desktop ad-desktop–8 ad-desktop–8-on-article”; elem.setAttribute(‘data-banner-type’, ‘desktop’); elem.setAttribute(‘data-banner-label’, ‘Anzeige’); document.getElementById(‘ad-desktop-8’).parentNode.appendChild(elem); AdController.render(‘iqadtile8’); if ( window.console typeof window.console.info === ‘function’ ) { window.console.info(‘AdController ‘ AdController.VERSION ‘ tile 8 desktop’) } } } if ( typeof AdController !== ‘undefined’ window.Zeit.isMobileView()) { if ( !document.getElementById( ‘iqadtile3’ ) ) { var elem = document.createElement( ‘div’ ); elem.id = ‘iqadtile3’; elem.className = “ad ad-mobile ad-mobile–3 ad-mobile–3-on-article”; elem.setAttribute(‘data-banner-type’, ‘mobile’); document.getElementById(‘ad-mobile-3’).parentNode.appendChild(elem); AdController.render(‘iqadtile3’); if ( window.console typeof window.console.info === ‘function’ ) { window.console.info(‘AdController ‘ AdController.VERSION ‘ tile 3 mobile’) } } }
Derartzugespitzt sounds that, of course, a rar idiotic idea. But at second glance it is not even bad, at least oretically. WasFacebook first of all in Australia Undanschließend also wants to test in US, UK and Canada is a procedure that has been used so much for years in fight against child abuse.
By pilot project, stakeholders must first contact EineEinrichtung of Australian government, various-safety-Commissioner, and describe ir concerns in an online form. Then you should send images in question to yourself via Facebook Messenger, so that you can come into contact with Facebook’s servers.
An employee gets to see pictures
The transmission cannot be end-to-end encrypted, even if messenger makes this possible in principle, because n company could not view and edit it. However, always active transport encryption in Messenger should at least make sure that no unauthorized person can intercept and view files.

At this point, Actualin specially trained Facebook staff gets to see material. So people who are afraid to become victims of revenge pornography must decide for mselves wher y can live with it. The employee checks to see if it is really a picture with which someone could be exposed, and n creates einenHash from it, a kind of digital watermark. What is left of such a picture looks something like this: 48008908c31b9c8f8ba6bf2a4a283f29c15309b1.
Versuchtnun someone else to upload same image, it will vonFacebooks algorithms matched with deposited hashes. Match, image is rejected, on Facebook, Instagramund in Messenger. Outsideccms Facebook ecosystem, it could be verbreitetwerden.
The original image is still stored for a short time — pixelated — to ensure that comparison of hash of Mitneu uploaded images really works. Then Esgelöscht and only hash remains on Facebook as company shares.

Image recognition systems can be tricked
For now, it is unclear how resistant technique is to subtle image manipulation. In AI research, it has become a sport to outas Google’s image recognition systems in this way, so that y hold a turtle for a weapon, for example. This often only requires subtle changes to image that a person would not notice. However, this requires special knowledge, which a vengeful ex-partner should not normally have.
Veränderungenwie a new crop or a reduction of image in any case is not enough to change hash einesBildes. Thus, Facebook’s system could not be circumvented with some certainty.
