"We need to think seriously about how to address this problem, [especially since] mobile devices are only going to become more and more popular," he continued. "This is an urgent issue we'll be dealing with."
Franken, a Minnesota Democrat who chairs the new Senate Judiciary Subcommittee on Privacy, Technology and the Law, heard testimony from Apple and Google executives today about how their mobile platforms collect and use location-based data, and what type of control users have over that information.
Google said that any location-based data it collects via its Android mobile operating system is anonymous in nature and the majority of that information is deleted after one week.
"The location information sent to Google servers when users opt in to location services on Android is anonymized and stored in the aggregate and is not tied or traceable to a specific user," said Alan Davidson, director of public policy at Google. "The collected information is stored with a hashed version of an anonymous token, which is deleted after approximately one week."
