Privacy ain't what it used to be.

Just a decade or so ago, most of us paled at the thought of sharing our phone numbers and addresses with corporations, knowing that an onslaught of junk mail and telemarketing calls would follow any slip-up.

Today, we distribute our contact info as freely as we'd hand out bland sheet cake at a six-year-old's birthday party. We have dozens of accounts for banking, shopping, and social media, most of which require our email addresses, phone numbers, and other personal information.

To be sure, the web has made our lives much easier. The internet and smartphones have allowed us to connect with friends and strangers in previously unimaginable ways. But there's a price to pay for all the info-sharing that we're doing. And in some parts of the country, folks are getting a preview of what privacy will look like later in the 21st century.


If you commute over a toll road or bridge, you probably have an E-ZPass (or something very much like it). Such devices use simple RFID technology to let drivers bypass booths and pay tolls on the go.

Last week, The Gothamist posted an article about an IT director in New York who'd hacked his E-ZPass to reveal when it was being read. As it turns out, the device wasn't just being scanned on toll roads, it was being read all over Midtown Manhattan.

City officials acknowledge that, yes, E-ZPasses are being scanned as part of a program to monitor and reduce traffic congestion in Manhattan. And that's not the only such project you'll find in NYC: there are other tracking systems in place, including one that photographs every vehicle that travels through the city's toll plazas, then stores those photographs for up to 45 days.

And don't think you're getting off easy if you don't have an E-ZPass or don't live in New York: as we mentioned a couple of months ago, licence plate-scanners are doing the same thing, tracking motorists in cities and towns across the U.S. -- and their databases aren't consistently cleaned out. Some records go back several years. 


Also in New York, the city's Taxi and Limousine Commission issued a whopping 22,000 citations to taxi drivers in fiscal year 2013. That's up from about 300 issued in 2009, or an increase of  7,233 percent.

What does that have to do with privacy? And why has there been such a huge jump in citations? Beginning in 2009, new regulations required hire cars in NYC to carry GPS trackers. So now, when customers complain that they were taken to the airport and charged the full toll rate instead of getting the E-ZPass discount, the TLC can look at its data records and say, "Yes, that cab went to the airport at that time, and no, it didn't have a the required E-ZPass, so the customer got charged the full toll."

And GPS locators aren't limited to cabs. Some of us willingly include similar devices on our personal vehicles through concierge systems like OnStar, anti-theft gadgets like LoJack, or via our insurance company (cf. Progressive Snapshot). How long until those gadgets become ubiquitous? Surely, it's just around the bend.


We already use our smartphones to keep track of things like airline boarding passes and frequent-shopper cards. But Portland, Oregon has become the latest metro area to launch a system that allows riders to pay for and manage public transportation tickets
