The tool designed to detect known images of child sexual abuse, called “neuralMatch,” will scan images before they are uploaded to iCloud. If it finds a match, the image will be reviewed by a human. If child pornography is confirmed, the user’s account will be disabled and the National Center for Missing and Exploited Children notified.
Matthew Green, a top cryptography researcher at Johns Hopkins University, warned that the system could be used to frame innocent people by sending them seemingly innocuous images designed to trigger matches for child pornography. That could fool Apple’s algorithm and alert law enforcement. “Researchers have been able to do this pretty easily,” he said of the ability to trick such systems.
