Duringthe introduction of Apple Intelligence at WWDC 2024 yesterday , Senior Vice President of Software Engineering Craig Federighi repeatedly vaunt the raw characteristic ’s security department and delicate treatment of sensitive substance abuser datum . To protect substance abuser privacy , Apple Intelligence performs many of its productive trading operations on - equipment . And for those that transcend its onboard capabilities , the system will transfer the oeuvre up to the company ’s freshly developed individual Cloud Compute ( PCC ) .
However , as Dr. Matthew Green , associate professor of Computer Science at Johns Hopkins University in Baltimore , asked in a train of thought Monday , Apple ’s AI cloud may be unafraid , but is it trusty ?

Apple Intelligence call to gift your iPhone , iPad , and Mac with cutting - edge generative models that can create trope , blue-pencil your writing , and perform action on your behalf across any number of apps . Apple gadget have already perform machine learning tasks on - gadget for a number of years ; take the tv camera roll ’s hunting use and optical character recognition ( OCR ) text recognition for instance . However , as Green points out , even the latest generation of Apple processor are n’t yet powerful enough to deal some of the more complex and resource - intensive AI operations come in online , necessitate the use of swarm compute servers .
The job is , these complex models also demand unencrypted admittance to the substance abuser ’s data point so as to perform inference functions and transmitting that data to a public swarm leaves it at peril of being hacked , leaked , or instantaneously slip . Apple ’s solution was to build its own standalone , harden data centers specifically for march Apple Intelligence data : the PCC . This “ groundbreaking cloud intelligence system , ” consort to a recentApple Security Blog mail , “ stretch out the industry - lead security system and seclusion of Apple devices into the swarm , making certain that personal substance abuser datum sent to PCC is n’t accessible to anyone other than the user — not even to Apple . ”
The problem is that while modern sound “ neural ” hardware is improve , it ’s not improving tight enough to take advantage of all the screwball features Silicon Valley want from mod AI , including generative AI and its like . This fundamentally requires servers . 3/

But see to it that privacy is much hard in practice . “ build up trusty computers is literally the hardest trouble in computer surety , ” Green wrote . “ Honestly , it ’s almost the only job in data processor security . ” He recommend the company on applying many of the same security features built into its fluid and desktop devices to its new host , include Secure Boot , “ homeless ” computer software , and a Secure Enclave Processor ( SEP ) , as well as “ throwing all kinds of processes at the server computer hardware to check that the hardware is n’t tampered with . ”
Apple has gone to great distance to ensure that the computer software running on its servers is legitimate , automatically wiping all exploiter data from a PCC knob as soon as the asking has been completed and activate the machine ’s operating system to “ attest ” to what software system image it ’s scat .
“ If you turn over an excellent squad a huge pile of money and evidence them to build the best ‘ individual ’ cloud in the earth , it would probably expect like this , ” Green wrote . “ But now the tough question . Is it a good idea ? Is it as secure as what Apple does today , ” and can users opt out ? It does n’t appear that user will even opt in to the new service . “ You wo n’t necessarily even be told it ’s hap , ” he uphold . “ It will just happen . Magically . I do n’t love that part . ”
Green give way on to fence that drudge do n’t even pose the biggest menace to user data point : it ’s the hardware and software package companies themselves . As such , “ this PCC system represents a existent commitment by Apple not to ‘ peek ’ at your data , ” Green reason . “ That ’s a big deal . ”
Apple Intelligence will reportedly begin rolling out subsequently this summer . And in the coming weeks , Apple plans to invite protection research worker for a first look at PCC package and the practical enquiry environment .
