According to a review provided by Apple, the security guide includes a number of new inputs and extensions specific to iOS 12, including secure enclaves for iOS devices, Express Card with power reserve, DFU and recovery mode, contactless passes, and security certificates and programs. . Marquee features such as Siri Suggestions, the Shortcuts app, Screen Time and HomeKit TV Remote accessories are also listed as a call theme & # 39; s.
Beginning with Siri, the document notes that Siri suggestions for apps and shortcuts on the device are generated using machine learning resources, while anonymized data is returned to Apple to provide more accurate predictions.
"Custom shortcuts are versatile, they look like scripts or programs." A quarantine system is used to isolate shortcuts downloaded from the Internet, "says Apple. "The user is alerted when he first uses the shortcut and gets the opportunity to inspect the shortcut, including information about where it comes from."
Shortcuts, enabled via an app of the same name, are synchronized via iCloud on all logged in devices, so that customizable Siri commands are available on multiple endpoints. All information is protected using end-to-end encryption of CloudKit and while voice recognition phrases are sent to Siri's servers, Apple does not receive the contents of created shortcuts.
A comprehensive overview of Screen Time, Apple's app usage tracking solution, is also included in the updated security guide. Apple notes that the new feature allows users to view usage data, set app or web usage limits, configure downtime and enforce additional restrictions. Downtime allows users to set time limits and rest hours in the app to control the use of the app.
Apple points out that parents can monitor Screen Time parameters and check the usage patterns, restrictions and tools of their children that can be turned off by the child on their eighteenth birthday.
If a user has the Share iPhone Analytics setting enabled on their device, Apple collects a small amount of anonymised data to understand how Screen Time is used. Data points include when Screen time is activated, whether it is enabled, or Downtime is enabled, the number of times the demand has been used and the number of app limits currently active on a device.
Important for users who have Express cards such as transit or student ID cards, Apple says that NFC cards can be used on the iPhone, even if iOS is not running due to too low a battery. According to the company, a device that needs to be charged may still have enough power to perform Expresscard transactions.
"Pressing the side button displays the empty battery icon, as well as text indicating that Express cards are available for use," says Apple. "The NFC controller performs express card transactions under the same conditions as when running iOS, except that transactions are indicated with a haptic notification only and no visible notification is displayed."
Help reduce battery usage, Express mode cards are accessible without Touch ID, Face ID or password verification.
Support for student IDs is also new in iOS 12. This feature allows students, teachers and staff to offer their ID card to Wallet through an app from the issuer. It is important that the publishing of apps must support two-factor authentication for account access, while adding the cards to Wallet automatically enables the Express mode.
A section on HomeKit TV Remote provides information about future support for Siri-compatible remote control hardware, including how the system handles Siri commands.
"External HomeKit TV accessories from third parties offer HID events and Siri audio to a corresponding Apple TV that has been added via the Home app" the paper s. "The HID events are transmitted through the secure session between the Apple TV and the remote control, and a Siri-compatible TV Remote sends audio data to the Apple TV when the user explicitly activates the microphone on the remote control with a special Siri button. to the Apple TV via a dedicated local network connection between the Apple TV and the remote "
