Apple recently announced some new ones possibilities ασφάλειας για παιδιά σε όλες τις πλατφόρμες του λογισμικού της. Οι νέες δυνατότητες θα κυκλοφορήσουν με τα λειτουργικά συστήματα iOS 15, iPadOS 15, WATCH 8 and macOS Monterey in the US later this year, and are aimed at curbing the spread of Child Sexual Abuse Material (CSAM), among other things.
One of the new features will essentially scan iPhones and iPads for CSAM and report them to the National Center for Missing and Exploited Children (NCMEC from National Center for Missing and Exploited Children). Apple claims that its known CSAM detection method is "designed with user privacy in mind." However, the company's statement does not reassure security experts.
According to a recent publication in the Financial Times, security researchers have warned that Apple's new tool could be used for surveillance, endangering the personal information of millions of people.
Their concern is based on data Apple shared with some US academics earlier this week. Two anonymous security researchers who attended Apple's briefing revealed that the proposed system (called “neuralMatch”) will proactively warn a group of people (inspectors) if it detects CSAM on an iPhone or iPad. Inspectors will then contact law enforcement if of course they are able to verify the material.
While many security researchers support Apple's efforts to curb the spread of CSAM, some have expressed concern that the tool could be misused by governments that could use it to gain access to their citizens' data.
Ross Anderson, a professor of safety engineering at Cambridge University, said:
"It's an absolutely horrific idea, because it is going to lead to distributed mass surveillance… of our phones and laptops."
Matthew Green, a professor of computer science at the Johns Hopkins Information Security Institute, also expressed concern in Twitter:
I've had independent confirmation from multiple people that Apple is releasing a client-side tool for CSAM scanning tomorrow. This is a really bad idea.

But even if you think Apple will not allow the misuse of these tools… there is still a lot to worry about. These systems are based on a database of problematic "media hashes" that you, as a consumer, can not control Has Hashes use a new and proprietary neural hashing algorithm developed by Apple and made NCMEC agree to use… No we know a lot about this algorithm. What if someone can decrypt it?
Although the algorithm is currently trained to detect CSAM, it could be adapted to scan for other targeted images or texts, such as anti-government-anarchist signals, making it an extremely useful tool for authoritarian governments.
