Coming Soon: Internet Devices That Reveal Where You Are

N E W Y O R K, Oct. 30 B Imagine walking by a Starbucks in an unfamiliar city. Your cell phone rings, and a coupon for coffee pops up on its screen, good only at that location.

How did your phone know you were even near that particular Starbucks? What else does it know about you?

Enter location tracking, coming to a mobile device near you. Features that one day can pinpoint your whereabouts to within the length of a football field raise enormous privacy concerns, but they also offer enormous benefits.

The challenge will be determining where to draw the line.

Digital Angel

Consider a technology to be unveiled today. Called Digital Angel, a microchip worn close to the body promises to record a personBs biological parameters and send distress signals during medical emergencies.

But misused, these types of capabilities could amount to virtual stalking.

Cell phones, handheld devices, even car navigation systems will soon have detailed tracking abilities, if they do not already. Services could begin appearing within a year or so.

Much of the drive will come from a federal law that requires cell phones to identify callersB locations to speed 911 emergency responses. If the industry has to install expensive equipment anyway, why not use it also to make money?

BThereBs going to be a dramatic increase in the amount of tracking thatBs made possible, in part by services they donBt know they have,B said Daniel J. Weitzner of the World Wide Web Consortium, which sets technical standards for the Web.

Such tracking will let someone visit a Web site and automatically get weather, movie showings or neighborhood restaurants, based on their current location. If theyBre lost, they will be able to ask for turn-by-turn directions. Those short of cash can be pointed to the nearest bank machine.

Big Brother Always With Us?

But if the information is stored, location tracking could result in a 24-hour-a-day record of a personBs whereabouts.

So what if a divorce lawyer wants to check if someoneBs been cheating, or if a social service agent wants to know how many times a person has visited a candy store with his child?

BYou have to ask, BWho gets how much information?BB said Jason Catlett, chief executive of Junkbusters Corp., a non-profit privacy monitoring group in Green Brook, N.J.

BTelephone records are routinely subpoenaed. They can be very intrusive, but far more intrusive is a complete log of your physical movement.B

But companies looking to gain business from location tracking insist that the worst-case scenarios presented are impractical to implement in reality.

BThereBs no way a database is large enough or cost effective for Starbucks to monitor everyoneBs location on the offchance they can acquire a customer,B said Jason Devitt, chief executive of Vindigo, which offers 11 city guides through Palm organizers.

Lee Hancock, founder and chief executive of go2 Systems Inc., said any short-term gains from such tactics would be offset by losses if they alienate customers.

Leading wireless and advertising companies agree that they must tread carefully because mobile devices are inherently more personal than desktop computers.

Slow Rollout

At DoubleClick Inc., whose ad-targeting system generated much of the NetBs privacy complaints, officials wonBt deliver location-based ads right away. The company wants to develop privacy standards first, using lessons from the desktop.

BWeBve all learned what to do and what not to do, and we can port that over to the wireless market,B said Jamie Byrne, strategic director for emerging platforms at DoubleClick.

Any such ads will likely target a metropolitan region, rather than a city block, because audiences for block-by-block ads would be too small, Byrne said. Ultimately, he said, such targeting will help subsidize wireless services that customers want.

Jonathan Fox, director of business development at advertising company Engage Inc., says location-based profiles would not carry names and other personal information.

TRUSTe, which runs a seal-of-approval program for Internet privacy policies, is looking to develop guidelines for mobile applications. Details that remain to be worked out include how to notify customers on a phoneBs small screen.

BItBs more difficult to retrofit policies if youBre already down the road,B said Robert Lewin, TRUSTe chief executive. BHere, we have the opportunity to do it right the first time.B

In many ways, a personBs whereabouts are already being tracked.

Employee security cards record when people enter buildings. Discount grocery programs track what people buy, where and when. Electronic toll-payment systems know when someone traverses a tunnel or bridge.

Location, Location, Location?

Current phones can pinpoint callers to a few miles by determining the location of the cell tower used to handle the call.

Palm VII organizers use similar techniques to narrow a user to a particular zip code, and an optional global-positioning receiver can pinpoint that person even further.

Marketers can also get clues from the items people search for or the sites they visitBa city guide, for instance, tells in what city a person is likely located or where they plan to visit.

But for the most part, marketers have yet to take full advantage of such knowledge, and consumers have yet to complain.

BWeBre providing value,B Palm spokesman Ted Ladd said. BMobile users are inherently in a hurry.B

Wireless providers are not likely to have a use for storing location information, except perhaps for applications that help with driving directions.

Paul Reddick, vice president of product management and development with Sprint PCS, said such storage is not practical, necessary or even desirable.

BIt takes years to build a brand and build trust,B he said, Band you can blow it pretty fast.B

The biggest impetus for cell-phone GPS has come from the federal government. According to an FCC mandate called E-911, wireless carriers must be able to specify a callerBs location to within 125 meters. The stated purpose for this rule is that callers using mobile phones should have the same access to emergency services as callers using stationary phones.

Right now, the callerBs location can be narrowed down to their cellB the area their calls originate from. But in most of the United States, cells are too large to meet the 125-meter requirement. This means that providers must either build their own infrastructures or install GPS receivers in their phones.
