Researchers reveal Android devices communicating with Google servers almost 90 times per hour

A team of researchers at Vanderbilt University have published a paper detailing how frequently Android devices communicate with Google servers to share user data and how this data can be used to identify individuals

Scenario 1
In order to get an accurate picture of just how much active and passive data collection was going on, the researchers set up a brand new Gmail account on a phone that had been factory reset. Additionally, they used a brand-new SIM card. These precautions allowed the researcher to ensure that Google had no usage data on the current user’s profile (named Jane). Then the researcher went about her day as normal, using this brand-new phone. This allowed the researchers to study the Active data being collected.

Scenario 2
In order to quantify the amount of passive data being collected, the team monitored data sent to Google from mobile phones (both Android and iPhone) within a 24-hour period. During this time, the phones were used by users, but with minimal interaction with Google Apps and services.

Once data had been collected from the three scenarios the researchers concluded that

Scenario 1

Scenario 2

  • Android smartphone communicated with Google Servers roughly 900 times in 24 hours whereas the Apple iPhone only makes 100 such requests.
  • During this time, Android smartphone shared location 14 times per hour while the iPhone shared no location data with Google.
  • The Apple iPhone made roughly 120 data connections with Apple servers. Half the times, the connection was for device upload in the form of photo/iOS backups.

Scenario 3
Android Smartphone communicated location information 450 times within 24 hours. A total number of communication requests were roughly 2100 times in 24 hours (approx.90/hour). The team points out that “The number of calls to Google’s advertising domains was similar from both devices - an expected outcome since the usage of 3rd-party web pages and apps was similar on both devices. One notable difference was that the location data sent to Google from an iOS device is practically non-existent. In the absence of Android and Chrome platforms—or the use of any other Google product—Google becomes significantly limited in its ability to track the user location

In Conclusion
The researchers conclude that the Android Platform combined with the use of Chrome (which tracks all your website visits and clicks) allows Google to collect an immense amount of information. While most of the information packets by themselves could be considered anonymous, the paper detail in excruciating detail how Google can easily link all the data packets collected to the user from whose device they originated. The paper is a scary look at Google’s pervasive reach into our lives. In comparison, Apple's iOS does restrict the data collection to a considerable degree, especially if people are to minimise their use of Google's applications on the platform.
