Apple to scan iPhones for images of child abuse, researchers raise concern

 

Apple unveiled plans to scan US iPhones for images of child abuse, drawing applause from child protection groups but raising concern among some security researchers that the system could be misused by governments looking to surveil their citizens.

Apple said its messaging app will use on-device machine learning to warn about sensitive content without making private communications readable by the company. The tool Apple calls neuralMatch will detect known images of child sexual abuse without decrypting people's messages. If it finds a match, the image will be reviewed by a human who can notify law enforcement if necessary.

But researchers say the tool could be put to other purposes such as government surveillance of dissidents or protesters.

Matthew Green of Johns Hopkins, a top cryptography researcher, was concerned that it could be used to frame innocent people by sending them harmless but malicious images designed designed to appear as matches for child porn, fooling Apple's algorithm and alerting law enforcement -- essentially framing people.
