In a briefing on Thursday afternoon, Apple confirmed previously reported plans to deploy new technology within iOS, macOS, watchOS, and iMessage that will detect potential child abuse imagery, but clarified crucial details from the ongoing project. For devices in the US, new versions of iOS and iPadOS rolling out this fall have “new applications of cryptography to help limit the spread of CSAM [child sexual abuse material] online, while designing for user privacy.”

The project is also detailed in a new “Child Safety” page on Apple’s website. The most invasive and potentially controversial implementation is the system that performs on-device scanning before an image is backed up in iCloud. From the description, scanning does not occur until a file is getting backed up to iCloud, and Apple only receives data about a match if the cryptographic vouchers (uploaded to iCloud along with the image) for a particular account meet a threshold of matching known CSAM.

For years, Apple has used hash systems to scan for child abuse imagery sent over email, in line with similar systems at Gmail and other cloud email providers. The program announced today will apply the same scans to user images stored in iCloud Photos, even if the images are never sent to another user or otherwise shared.
