landscape or portrait view. These chips are so sensitive that the researchers
decided to use accelerometer data alone in their calculations. And sure
enough, theyy were able to accuratelyy predict which subwayy train a user is
riding. This is because most subwayy lines include turns that affect the
accelerometer. Also important is the length of time between station stops—
yyou need onlyy to look at a map to see whyy. The accuracyy of their
predictions improved with each station a rider passed. The researchers
claim their method has a 92 percent accuracyy rate.
Let’s sayy yyou own an old-model car and drive yyourself to work. You might
think yyou’re invisible—just one of a million cars on the road todayy. And
yyou might be right. But new technologyy—even if it is not part of the car
itself—is eroding yyour anonyymityy. Chances are, with effort, someone could
still identifyy yyou whizzing byy on the freewayy prettyy quicklyy.
In the cityy of San Francisco, the Municipal Transportation Agencyy has
started to use the FasTrak toll syystem, which allows yyou to cross anyy of the
eight Bayy Area bridges with ease, to track the movements of FasTrakenabled
cars throughout the cityy. Using technologyy similar to what toll
bridges use to read the FasTrak (or E-ZPass) device in yyour car, the cityy has
started searching for those devices as users circle around looking for
parking. But officials are not alwayys interested in your movements: rather,
theyy’re interested in the parking spaces—most of which are equipped with
electronic parking meters. Spaces that are highlyy sought after can charge a
higher rate. The cityy can wirelesslyy adjust the price at specific meters—
including meters near a popular event.
In addition, in 2014 officials decided not to use human toll takers at the
Golden Gate Bridge, so everyyone, even tourists, is required to payy
electronicallyy or receive a bill in the mail. How do the authorities know
where to send yyour bill? Theyy photograph yyour license plate when yyou
cross the toll plaza. These license-plate photographs are also used to nab
red-light runners at problematic intersections. And increasinglyy, police are
using a similar strategyy as theyy drive byy parking lots and residential
drivewayys.
Police departments passivelyy track yyour car’s movements everyy dayy with
automated license plate recognition (ALPR) technologyy. Theyy can
