What's New in Privacy

Apple introduced several new privacy features and improvements at WWDC 2024, focusing on enhancing user control and transparency. Here are the key updates:

1. Privacy Pillars:

   • Data Minimization: Collect only the minimum amount of data required.
   • On-Device Processing: Perform computations locally to avoid server-side exposures.
   • Transparency and Control: Make it clear what data is collected and give users control over its use.
   • Security: Provide technical guarantees and enforcement of privacy protections.

2. New Pickers:

   • Introduced new pickers that allow users to share only the data they want without permission prompts. These include customizable UI elements that fit seamlessly into apps while minimizing data sharing.

3. Platform Protections:

   • Private Wi-Fi Controls: Introduced Mac address rotation on iOS and macOS to prevent tracking through stable Mac addresses.
   • Local Network Privacy: Enhanced controls and descriptions for local network usage to ensure transparency.

4. Permission Changes:

   • Contacts Access: iOS 18 introduces a two-stage prompt for sharing contacts, allowing users to select specific contacts rather than granting full access.
   • Bluetooth Access: Improved permission flows for Bluetooth accessories using the Accessory Setup Kit.

5. Locked and Hidden Apps:

   • New system feature that allows users to lock sensitive apps, providing peace of mind when sharing devices with others.

6. Automatic Passkey Upgrades:

   • Encourages the adoption of passkeys for secure and easy sign-ins, reducing the need for password management.

7. Private Caller ID:

   • Tools for implementing live caller ID using homomorphic encryption, ensuring that servers can provide caller information without learning who is calling.
