iOS 8 Tidbits: Randomized MAC Addresses, Safari Credit Card Scanning, Indoor Mapping, and More

With iOS 8 installed on thousands of developer devices, details about the operating system continue to leak out. We covered quite a few new iOS 8 features listed during the keynote by Apple, including battery usage by app, and then followed that up with even more iOS 8 tweaks and changes, such as time-lapse mode, Messages improvements, WiFi calling, and grayscale mode.

Pulling from an extensive list maintained by our forum members and other iOS 8 users on Twitter and the web, we've catalogued even more improvements to the operating system below.

Randomized MAC addresses - iOS randomizes the MAC addresses of iOS devices when scanning for WiFi networks, which makes it more difficult for companies to track and gather location data on a customer. Each iOS device has a unique MAC address, which could previously be used for location tracking and data collection via WiFi scanning. iOS 8 will use random, locally administered MAC addresses that "may not always be the device's real (universal) address."

Safari credit card scanning - In iOS 8, Safari can utilize the camera to scan in credit card numbers when making online purchases, a faster alternative than manually entering a credit card number. Currently, this scanning function is available in the App Store to scan in iTunes Cards, and the credit card scan functions in the same way.

Photos in the Notes app - Photos can be inserted into the Notes app from the Photos app for the first time in iOS 8.

Hide images from Photos app - Images in the Photos app can now be hidden from the Moments, Collections, and Years view in the Photos app. Holding a finger on a photo will bring up an options menu and selecting "Hide" will keep it from being visible in those sections. Hidden photos are still visible in the albums view, however, in new "Hidden" album.

Background location notifications - iOS 8 has new popups that will notify users of apps that access Location information while running in the background. The popup asks users if they want to continue to allow the apps to access the information or turn it off, giving users more information on apps that could potentially be using a lot of battery life. There are also more Location Services options in the Settings menu and more options per app, for more control over how Location is used.

backgroundlocation
iTunes Radio Control Center - When playing a song on iTunes Radio, the Control Center will now offer a "Buy" button to give users a quick way to purchase a song.

buybutton
Indoor Mapping - iOS 8 adds the M7 processor and iPhone motion sensors to the CoreLocation API, allowing venue owners to create indoor positioning systems. In use at San Francisco's California Academy of Sciences, the Westfield Center in San Francisco, and the San Jose Airport, the system can be used to display floor number or direct users to points of interest.

Keep up with all of the new changes introduced in iOS 8 on our forums, where our readers are discussing and sharing feature enhancements and tweaks in the "iOS 8, All The Little Things" thread.

If there's no way to disable this randomised MAC stuff, then no iOS 8 device is going to be able to connect to my network at home, or my corporate network at work.

It also means that networks which rely on MAC for authentication (such as the WiFi on the underground here in London) won't work.

Bit silly if you ask me. I'm not sure how a randomised MAC address helps improve security in any way.


This is a privacy issue, not a security issue. And I'm sure you'll still be able to connect to your networks. Give Apple a little credit.

Will MAC address randomization mess up people who have MAC filtering on their wireless networks? Is it required?


I think it's only when you're not connected (scanning) for a network. When you connect it uses the proper MAC address.

This.

Randomized MAC addresses will stop all those nefarious wi-fi customer tracking systems (http://www.washingtonpost.com/blogs/the-switch/wp/2013/10/19/how-stores-use-your-phones-wifi-to-track-your-shopping-habits/) from working properly on a randomized MAC device.

MAC randomization, clear/simple app permission management, DuckDuckGo, double-checking that you want to be tracked, strict sandboxing of apps and extensions... security and privacy really are king at Apple. How's Android innovation doing on that front? :p

With iOS 8, we have our cake and eat it too: the flexibility and extensibility that Android crammed in first (with too little regard for safety) but done carefully and correctly, built on a deep security architecture. There's no "band-aid" Google can invent to bring that kind of safety and privacy to Android. But privacy isn't really Google's core mission...

Just ask someone. It's more social and keeps the world friendly.


Yeeeaaaaah it also makes for a long trip to the grocery store when you have to keep asking where stuff is...

I agree with star flyer, give me a Safeway/Kroger app in which I can enter my shopping list, and the app will line all my entries up and show me where they are as I walk through the store. Completely efficient, and no need to bother the kid stocking the shelves to show me where the tomato sauce is located.

I can see grocery stores making use of the indoor mapping feature. I don't know how many times I wish I could pull up maps to find the tomato sause when my wife sends me to the store.
