GitHub user AsuharietYgva reportedly outlined details of the NeuralHash system Apple uses while user dxoigmn seemingly claimed to have tricked the system with two different images that created the same hash. Additionally, there is an appeals process in place for anyone who feels their account was flagged and disabled in error.Ī report in August, however, seemingly proved that the system is fallible. And if it does happen, an human review would catch it before it escalated to the authorities. Since the system is only scanning for known images, Apple says the likelihood that the system would incorrectly flag any given account is less than one in one trillion per year. Federighi emphatically stated that the system is “literally part of the pipeline for storing images in iCloud.”Ĭould the system mistake an actual photo of my child as CSAM? Federighi said “the cloud does the other half of the algorithm,” so while photos are scanned on the device it requires iCloud to fully work. For one, Apple says the system does not work for users who have iCloud Photos disabled, though it’s not totally clear if that scanning is only performed on images uploaded to iCloud Photos, or all images are scanned and compared but the results of the scan (a hash match or not) are only sent along with the photo when it’s uploaded to iCloud Photos. But Apple is scanning photos on my device, right? An Apple employee will only see photos that are tagged as having the hash and even then only when a threshold is met. As Apple explains, the system is strictly looking for “specific, known” images. Apple further transforms this database into an unreadable set of hashes that is securely stored on users’ devices. Here’s how Apple explains the technology: Instead of scanning images in the cloud, the system performs on-device matching using a database of known CSAM image hashes provided by the National Center for Missing and Exploited Children (NCMEC) and other child safety organizations. In an interview with Joanna Stern from the Wall Street Journal, Craig Federighi said the reason why it’s releasing in iOS 15 is that “we figured it out.” CSAM scanning Does the scanning tech mean Apple will be able to see my photos? Songs from the Apple Music catalog cannot be burned to a CD.The new CSAM detection tools will arrive with the new OSes later this year. iTunes-compatible CD or DVD recorder to create audio CDs, MP3 CDs, or backup CDs or DVDs.
