Sprint Provides U.S. Law Enforcement with Cell Phone Customer Location Data: Via Schneier on Security.

Wired summarizes research by Christopher Soghoian:

Sprint Nextel provided law enforcement agencies with customer location data more than 8 million times between September 2008 and October 2009, according to a company manager who disclosed the statistic at a non-public interception and wiretapping conference in October.

The manager also revealed the existence of a previously undisclosed web portal that Sprint provides law enforcement to conduct automated "pings" to track users. Through the website, authorized agents can type in a mobile phone number and obtain global positioning system (GPS) coordinates of the phone.

From Soghoian's blog:

Sprint Nextel provided law enforcement agencies with its customers' (GPS) location information over 8 million times between September 2008 and October 2009. This massive disclosure of sensitive customer information was made possible due to the roll-out by Sprint of a new, special web portal for law enforcement officers.

The evidence documenting this surveillance program comes in the form of an audio recording of Sprint's Manager of Electronic Surveillance, who described it during a panel discussion at a wiretapping and interception industry conference, held in Washington DC in October of 2009.

It is unclear if Federal law enforcement agencies' extensive collection of geolocation data should have been disclosed to Congress pursuant to a 1999 law that requires the publication of certain surveillance statistics -- since the Department of Justice simply ignores the law, and has not provided the legally mandated reports to Congress since 2004.

Sprint denies this; details in the Wired article. The odds of us ever learning the truth are probably very low.
