According to the Australia Broadcasting Corporation, Facebook has partnered with the office of the Australian government’s e-Safety Commissioner, which works primarily to prevent the online abuse of minors, to develop the new system for combating the nonconsensual sharing of explicit media. >By uploading the images or videos you fear may be shared in the future in an attempt to shame or harass you online, Facebook can digitally “hash” the media, effectively giving it a digital footprint. This allows the social network to track the media using the same artificial intelligence-based technologies it uses in its photo and face matching algorithms, and then prevent it from being uploaded and shared in the future. This works only if you’re in possession of the original file, but it would seem to bypass any attempts from a malicious third party to alter the metadata by analyzing and tagging the actual content of the image or video.
