Documents in icloud drive encrypted?

[ajaan]

Apple on their iCloud security page states that iCloud drive is encrypted. However, what is less clear is who holds the key. Is it encrypted by my computer/iPad/iPhone or do Apple hold the key. I don't really want my medical information on documents in iCloud if it's not secure.

Anyone have a definitive answer on this not based on speculation.

Thanks.

AFAIK, Apple holds the key. As to security, its just as secure as your banking information or your health information, provided you are willing to take a leap of faith and believe what Apple are saying about not reading your data.

Thanks. Regarding health information though in the UK the health data is not uploaded or shared across providers if a person has opted out. Therefore, the only people who can access it are your doctor, in that specific surgery, using their ID card to get into the records. The doctors are bound by the their medical council to patient confidentiality. In addition, the records are subject to data protection from EU and UK data protection law. Whereas if the files are sent over to the US via iCloud they are no longer subjected to UK data protection laws.

Does iCloud use client-side encryption? - Ask Different – there was an accepted answer in July 2012. Whether things have changed since then, I don't know.
