(Original story below for context.)Īpple is reportedly set to announce new photo identification features that will use hashing algorithms to match the content of photos in users’ photo libraries with known child abuse materials, such as child pornography.Īpple’s system will happen on the client - on the user’s device - in the name of privacy, so the iPhone would download a set of fingerprints representing illegal content and then check each photo in the user’s camera roll against that list. Update: This has now been officially announced: notably your phone will only be scanning photos uploaded to iCloud, in line with policies of all major social networks and web services.
