Privacy?

Privacy at WWDC 2024

At WWDC 2024, Apple introduced several new privacy features and enhancements across its platforms, emphasizing the importance of privacy as a fundamental human right. Here are some key highlights from the session titled "What’s new in privacy":

1. Privacy Pillars: Apple's approach to privacy is built on four main pillars: data minimization, on-device processing, transparency and control, and security. These principles guide the design of Apple's platforms to protect user data.

2. New Features in iOS 18 and macOS Sequoia:

   • Data Sharing Pickers: New pickers allow users to share only the data they want, minimizing unnecessary data exposure. These pickers are customizable to fit seamlessly into apps.
   • Locked and Hidden Apps: Users can lock and hide apps, requiring authentication (Face ID, Touch ID, or passcode) to access them, thus protecting sensitive information.
   • Improved Permission Dialogues: Permission dialogues have been clarified to better outline what data is being shared, enhancing user transparency and control.
   • Local Network Privacy: Changes in local network privacy require apps to include a local network usage description to access certain network features.

3. Private Information Retrieval: This technology allows for features like live caller ID without revealing sensitive information, such as phone numbers, by using private information retrieval techniques.

4. AdAttributionKit: A new framework for privacy-preserving ad attribution, building on the principles of crowd anonymity, which limits data sent back to ad networks based on conversion rates.
