Tracking Caucusgoers By Their Cell Phones (schneier.com)
Okian Warrior writes: Dstillery gets information from people's phones via ad networks. When you open an app or look at a browser page, there's a very fast auction that happens where different advertisers bid to get to show you an ad. Your phone sends them information about you, including, in many cases, an identifying code (that they've built a profile around) and your location information, down to your latitude and longitude. On the night of the Iowa caucus, Dstillery flagged auctions on phones in latitudes and longitudes near caucus locations, some 16,000 devices. It then looked up the characteristics associated with those IDs to make observations about the kind of people that went to Republican caucus locations versus Democrat caucus locations. It drilled down farther by looking at which candidate won at a particular caucus location.
what next?
Anybody else read that as "Tracking Caucasians By Their Cell Phones"?
I must say I was rather interested in the technology involved.
Sex. Drugs, and Unix.
I wonder what people would think if they fully understood how they are being tracked by ad companies.
While disturbing, this news is by no means surprising.
Advertastards can wave their hands and shout "we're just trying to see what you like so we can send you info on stuff you might find interesting!" until they're blue in the face, but simply having the vast reams data considered 'necessary' to 'get to know' the vict^H^H^H^Hcustomer is too much temptation for some to resist.
Of course, political advertising is still, well, advertising, and they're still trying to sell something to you, even if it's only a predefined set of prejudices or empty promises. So I suppose in the broadest sense this is a legit business purpose for Dstillery...but the ramifications are just a wee bit chilling. The stakes on this sort of ad campaign are a bit higher than whether people buy a Ford or a Toyota, and the one that they don't 'buy' doesn't have access to a list of people who ultimately didn't buy what they were selling...

In every state I've ever lived in, when you went to cast your vote in the primary elections, you had to ask for the ballot of a specific political party, because that is what a primary is. You narrow down the candidates from a political party into a single candidate for that political party for each specific public office.
The ballot you ask for is public record, which is how you always seem to get advertisements in the mail for one party but not the other, robo calls that attack one party but not the other, etc.
If some advertising company already knows who you are, they probably also already know who you vote for. Except in Iowa, apparently.
I currently live in Illinois and our election schedule is insane. We have elections twice a year sometimes it seems. If I don't particularly care about anyone in particular in an election, I will randomize which ballot I ask for in the primary. That seems to be very confusing to the people who profile me; I get asked to be a republican poll worker at the same time I get calls from Democrats, etc.
The only questions this should raise is how much jail time these data grabbers should get and why there's no one campaigning on privacy rights.
Because they need to be able to do this, for your safety.

Very fast? Not in my experience - it's fucking slow, so much so that it turns me off many websites. Now, if a website spends more than about ten seconds doing these shinanegins (as can be seen in the staus bar) I go elsewhere.
It suprises me that most people (even a website developer I was talking to recently) are unaware that this bidding goes on. They just think that their connection is slow.

Android question. I already have Firefox with addblock on my phone, but how do I make sure the browser and/or the adds (in case they are handled externally from the browser ) NEVER has access to the GPS ? Note that I don't want to turn GPS off since I often use it for navigation...

Joke's on them...I don't carry a cell phone everywhere I go. I rather enjoy escaping life's parasites for a few hours when I go out. They'll still be there when I decide to return home, all while the privacy invaders think I never left in the first place.

Generally speaking, if you can see multiple separate requests visible in your browser then what is going on is a traditional "waterfall" approach, where code in the page tries one ad server at a time until one succeeds.
The auction (real-time bidding, or RTB) model was invented to get around the limitations that the waterfall presents, allowing a middle-man (the "ad exchange") to accept an impression request, then take bids from many potential advertisers in parallel (generally they only got on the order of hundreds of milliseconds to respond) and then give the impression to the highest bidder.
Properly-implemented RTB should actually speed things up, since the action request from your browser should take no longer than 500ms. Of course, once the auction is completed the ad must still be downloaded and rendered and that itself can take some time depending on how "heavy" the ad is.
