In the first half of 2021 Apple announced they would begin checking photos on Apple devices for child pornography and many privacy advocates became concerned that Apple was overreaching. On August 5th Apple explained the details in highly technical terms that most people can’t understand. So we decided to simplify the process to four steps everyone can understand:
CLICK TO EXPAND GRAPHIC
The formula that is used to create the the serial numbers is smart enough to adjust for minor changes to an image, like cropping the edge off to make the photo smaller or changing its resolution.
What Apple is doing is moving the check for child pornography from their cloud services to your local device. This will catch many more child predators and will reduce the work Apple’s cloud servers have to do.
In a word, no. Virtually all of the tech companies you can think of, Google, Apple, Microsoft… do the same mathematical comparison looking for known CHILD porn images when photos are uploaded to their cloud services (think iCloud, OneDrive, Google Drive…)
The list of know child porn images is managed by the good people at the National Center For Missing & Exploited Children (aka NCMEC).
While this technology easily could be extended to peer inside your phone / tablet and see what is happening, today, with this limited use URTech.ca thinks it is a good idea.
We think that Apple can be trusted to use this technology the way they say they will today. That being said this is the top of a VERY slippery slope and that in the years to come so governments and consumers need to keep a careful eye on Apples use.
Note that we are big supporters of the CSAM Scanning Tool on Cloudflare.
There are many good articles written on the subject and we liked the Daily Tech News Shows version the best. It is clear, easy to understand and discusses the problems with this technology in a serious but rational way.
The best line in this video is:
“… its never the intended use that is the problem; it is the unintended use…”
