Apple’s service is extremely popular with Apple users as a way to store photos and videos as back up or to prevent their devices from filling up. But, some users might not know that the company uses other cloud storage technology to store Apple user data.
In a recent information release Apple stated in it’s iOS Security Guide that it encrypted iCloud account data in third party services including Google Cloud Platform and Amazon S3.
Stated in the recent update of iOS Security Guide,
“ The encrypted chunks of the file are stored, without any user-identifying information, using third-party storage services, such as S3 and Google Cloud Platform. “
It seems Microsoft Azure has been replaced with Google Cloud Platform and Amazon S3 has continued to remain as a trusted third party service to store additional data.
iCloud stores various documents, photos, videos, contacts, and more but since each file is broken into into chunks and encrypted with AES-128 and SHA-256 keys, security should not be an issue even with the usage of third party service for storing data.
The recent change went undetected before being spotted by CNBC. A rumour that Apple relied on Google Cloud Platform was present in 2016 but was never confirmed. The report doesn’t state if Apple uses Google for for services outside of storing photos and videos, nor does it disclose the start date for when Apple first started using Google as a storage platform.
