In “Google Data Collection,” Professor Douglas C. Schmidt, Professor of Computer Science at Vanderbilt University, catalogs how much data Google is collecting about consumers and their most personal habits across all of its products and how that data is being tied together.
The key findings include:
- A dormant, stationary Android phone (with the Chrome browser active in the background) communicated location information to Google 340 times during a 24-hour period, or at an average of 14 data communications per hour. In fact, location information constituted 35 percent of all the data samples sent to Google.
- For comparison’s sake, a similar experiment found that on an iOS device with Safari but not Chrome, Google could not collect any appreciable data unless a user was interacting with the device. Moreover, an idle Android phone running the Chrome browser sends back to Google nearly fifty times as many data requests per hour as an idle iOS phone running Safari.
