If you have been the victim of “revenge porn” – intimate pictures stolen and published in an attempt to humiliate or blackmail – Facebook has a proposal that might sound counterintuitive: cc them in to your sexts. But give it a chance. The company’s offering is a better idea than it sounds. Facebook has spent years working with other large technology firms to build software that can identify problem images the second they hit the net, and flag and remove them without the need for human intervention. The scheme, which has already been trialled in Australia, will be tested in the UK from this week. With brand names such as PhotoDNA, the technologies create a digital fingerprint or “hash” of an image or video, which can then be compared to future uploads to find matches and remove them automatically. It is good enough that it doesn’t get fooled by simple alterations such as colour tweaks, watermarks or crops, and it has already successfully been put to use in tackling terrorist propaganda and child abuse imagery posted online. But the problem with revenge porn is that it is hard to know what to put on the banned list in the first place. You can’t search for “revenge porn”: for one thing, a lot of it is actually just mislabeled non-revenge porn (not a problem for Facebook, which also bans that, but more of an issue for companies with less-strict controls on adult content). But more importantly, if something has already been published and flagged, it may well be too late to take down future uploads: someone’s life could already be ruined. And what if the pictures are being shared in a closed group, where the subject isn’t even aware they’re bring leered over? Read All Comments:
