Sarah Herrlinger, Apple’s Global Accessibility Chief Talks Tech

Andrew Orr ·

Sarah Herrlinger, Apple’s Global Accessibility chief, talks about new accessibility features in iOS 13 and macOS Catalina.

Accessibility, as it always does, plays a significant role in not only the conference itself — the sessions, labs and get-togethers all are mainstays of the week — but also in the software Apple shows off. Of particular interest this year is Apple’s Voice Control feature, available for macOS Catalina and iOS 13 devices, which allows users to control their Macs and iPhones using only the sound of their voices.

The new features, such as Voice Control, are amazing.

The Clever Cryptography Behind iOS 13 ‘Find My’

Andrew Orr ·

iOS 13 ‘Find My’ combines Find My Friends and Find My iPhone. Apple says it uses Bluetooth signals from Apple devices even if they’re offline. And the encryption scheme it uses means that third party attackers can’t track Apple devices, and Apple can’t track them either.

In a background phone call with WIRED following that keynote, Apple broke down that privacy element, explaining how its “encrypted and anonymous” system avoids leaking your location data willy nilly, even as your devices broadcast a Bluetooth signal explicitly designed to let you track your device. The solution to that paradox, it turns out, is a trick that requires you to own at least two Apple devices. Each one emits a constantly changing key that nearby Apple devices use to encrypt and upload your geolocation data, such that only the other Apple device you own possesses the key to decrypt those locations.

Apple Thwarts Sensor Fingerprinting With iOS 12.2

Andrew Orr ·

A study called “SensorID: Sensor Calibration Fingerprinting for Smartphones” examined sensor fingerprinting techniques against smartphones. It found that Micro Electro Mechanical Systems (MEMS) are inaccurate in small ways that make them unique. But Apple thwarted this technique in iOS 12.2 and used the researchers’ suggestion to add random noise to the analog-to-digital converter output and removing default access to motion sensors in Safari.

We demonstrate that our approach is very likely to produce globally unique fingerprints for iOS devices, with an estimated 67 bits of entropy in the fingerprint for iPhone 6S devices. In addition, we find that the accelerometer of Google Pixel 2 and Pixel 3 devices can also be fingerprinted by our approach.
