New legislation might stop companies & big brother from spying on your smart phone.

There are three things that matter in consumer data collection: location, location, location. 

E-ZPasses clock the routes we drive. Metro passes register the subway stations we enter. A.T.M.’s record where and when we get cash. Not to mention the credit and debit card transactions that map our trajectories in comprehensive detail — the stores, restaurants and gas stations we frequent; the hotels and health clubs we patronize. 

Each of these represents a kind of knowing trade, a conscious consumer submission to surveillance for the sake of convenience. 

But now legislators, regulators, advocacy groups and marketers are squaring off over newer technology: smartphones and mobile apps that can continuously record and share people’s precise movements. At issue is whether consumers are unwittingly acquiescing to pervasive tracking just for the sake of having mobile amenities like calendar, game or weather apps. 

For Senator Al Franken, the Minnesota Democrat, the potential hazard is that by compiling location patterns over time, companies could create an intimate portrait of a person’s familial and professional associations, political and religious beliefs, even health status. To give consumers some say in the surveillance, Mr. Franken has been working on a locational privacy protection bill that would require entities like app developers to obtain explicit one-time consent from users before recording the locations of their mobile devices. It would prohibit stalking apps — programs that allow one person to track another person’s whereabouts surreptitiously. 

The bill, approved last month by the Senate Judiciary Committee, would also require mobile services to disclose the names of the advertising networks or other third parties with which they share consumers’ locations. 

“Someone who has this information doesn’t just know where you live,” Mr. Franken said during the Judiciary Committee meeting. “They know the roads you take to work, where you drop your kids off at school, the church you attend and the doctors that you visit.” 

Yet many marketers say they need to know consumers’ precise locations so they can show relevant mobile ads or coupons at the very moment a person is in or near a store. Informing such users about each and every ad network or analytics company that tracks their locations could hinder that hyperlocal marketing, they say, because it could require a new consent notice to appear every time someone opened an app.

Some advocacy groups view location tracking by mobile apps and ad networks as a parallel, warrantless commercial intrusion. To these groups, Mr. Franken’s bill suggests that consumers may eventually gain some rights over their own digital footprints. 
“People don’t think about how they broadcast their locations all the time when they carry their phones. The law is just starting to catch up and think about how to treat this,” says Marcia Hofmann, a senior staff lawyer at the Electronic Frontier Foundation, a digital rights group based in San Francisco. “In an ideal world, users would be able to share the information they want and not share the information they don’t want and have more control over how it is used.”
