Apple Inc. is upgrading security protections on its devices, adding the ability to encrypt iCloud data backups for the first time alongside new safeguards for iMessage and account logins.
The most significant new feature, Advanced Data Protection for iCloud, will end-to-end encrypt the storage of iCloud backups — a nearly full copy of the data on a user’s iPhone and iPad — in addition to notes, photos, files, voice memos and messages. Previously, only some features, such as health data, passwords and payment information, were end-to-end encrypted.
