The Clever Cryptography Behind iOS 13 ‘Find My’

· · Link

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's WWDC Memoji Makeup Tutorial Starring Patrick Starrr and Desi Perkins

· · Cool Stuff Found

Apple unveiled enhancements to Memoji for iOS 13 during Monday’s WWDC keynote address, including a variety of customizations designed to help you make your Memoji look more like you. What was interesting to me was the “Makeup Tutorial” starring Patrick Starrr and Desi Perkins. These two younger folks are beauty influencers. What that means is that they make a bunch of beauty and makeup videos and have more followers than you can shake a stick at. What they are not are tech executives. Or coders. Or traditional celebrities. Or even project managers in Apple’s Memoji team. So, this represents Apple stepping outside the box, and it also means Apple is thinking differently about how to reach young people. Tapping social media influencers to spread the word about new customization features in Memoji means that Apple is targeting millennials and Generation Z. What it also means is that if you think this video is stupid or a bad idea, you aren’t the target market, and that’s OK. As it is, these new customization features are yet another step in Apple’s inexorable push in making iMessage a social media platform unto itself.

iOS Mouse Support Could Come This Year

Federico Vittici and Steve Troughton-Smith are saying that iOS mouse support could be coming this year as an accessibility feature of iOS 13. Mr. Vittici mentioned it on the Connected podcast, while Mr. Smith confirmed the rumor via Twitter.

I personally don’t see the need for a mouse on a touch-oriented device. But I’m glad it will be optional, instead of a required component of iOS. Edit: 20190425: I take that back.  I didn’t think of the scenario where many people can hook up an external monitor to their iPad. In that case, mouse support is perfect.

News+: What Kind of an iPad Homescreen Redesign Will iOS 13 Bring?

Writing for the Macworld magazine, Jason Snell shares some ideas for a rumored iPad homescreen redesign in iOS 13.

After more than a decade using more or less the same old app-launching interface Apple introduced with the original iPhone, it takes some effort to imagine how Apple could reinvent the concept of a home screen for the iPad. But reader, I’ve managed to make that effort. Here’s a look at some directions I hope Apple will go, assuming Gurman’s sources are right, when we first see this feature this summer.

One: I cannot wait for WWDC this year to see what iOS 13 brings. I hope the rumors are true that it will be an iPad-heavy release like iOS 11.

Two: This is the first of an occasional magazine article I’ll share as one of our Linked Teasers. Just a way to help people find cool content in Apple News+.
