Apple has introduced new tools to detect child sexual abuse material on iPhones and iPads, which will scan images before they are uploaded to iCloud. The company has faced criticism from privacy groups, who argue that the technology could be used by authoritarian governments to spy on citizens. Apple's software chief has acknowledged that the announcement was 'jumbled pretty badly' and has sought to clarify how the tools work. The tools are due to be added to new versions of iOS and iPadOS later this year.
