Securing and Extracting Health Data: Apple Health vs. Google Fit

Wednesday, January 30th, 2019

Today’s smartphones and wearable devices collect overwhelming amounts of data about the user’s health. Health information including the user’s daily activities, workouts, medical conditions, body measurements and many other types of information is undoubtedly one of the most sensitive types of data. Yet, smartphone users are lenient to trust this highly sensitive information to other parties. In this research, we’ll figure out how Apple and Google as two major mobile OS manufacturers collect, store, process and secure health data. We’ll analyze Apple Health and Google Fit, research what information they store in the cloud, learn how to extract the data. We’ll also analyze how both companies secure health information and how much of that data is available to third parties.

Apple Health: the All-in-One Health App

The Apple Health app made its appearance in 2014 with the release of iOS 8. Since then, Apple Health is pre-installed on all iPhones.

Apple Health keeps working in background, collecting information about the user’s activities using the phone’s low-energy sensors.

In addition to low-energy sensors built into modern iPhone devices, Apple offers a range of companion devices that can collect additional information about the user’s health and activities. This information may include heart rate measurements, frequent and precise samples of location information (GPS), as well as specific data (fall detection, ECG). (more…)

Meet iOS 11.3: Apple to Make It Harder for Law Enforcement to Extract iPhone Data

Thursday, January 25th, 2018

Forget battery issues. Yes, Apple issued an apology for slowing down the iPhone and promised to add better battery management in future versions of iOS, but that’s not the point in iOS 11.3. Neither are ARKit improvements or AirPlay 2 support. There is something much more important, and it is gong to affect everyone.

Apple iOS is (and always was) the most secure mobile OS. FBI forensic expert called Apple “evil genius” because of that. Full disk encryption (since iOS 4), very reliable factory reset protection, Secure Enclave, convenient two-factor authentication are just a few things to mention. Starting with iOS 8, Apple itself cannot break into the locked iPhone. While in theory they are technically capable of creating (and signing, as they hold the keys) a special firmware image to boot the device, its encryption is not based on a hardware-specific key alone (as was the case for iOS 7 and older, and still the case for most Androids). Instead, the encryption key is also based on the user’s passcode, which is now 6 digits by default. Cracking of the passcode is not possible at all, thanks to Secure Enclave. Still, in come cases, Apple may help law enforcement personnel, and they at least provide some trainings to FBI and local police.
