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.

    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.

      When you vote in a primary election, you sign a piece of paper attesting to your party affiliation as a matter of public record. That means the parties and the state already have your name and address with your political affiliation. It is not a secret, it's long been harvested.

      This is slightly different. This is correlating political candidates with advertising demographic data. They already know when a phone is used to check NASCAR results or is used to shop for lawn-mowers. What they did is identify which phones went to which primary polling place. By looking at places that had highly lopsided outcomes they were able to figure out that NASCAR fans supported Clinton, and lawn-mower owners in Iowa chose Trump.

      It's also not a given that they have collected your name and address. iPhones have an advertising privacy setting that determine whether or not your phone delivers a unique static token to the iAd companies. Turn the setting off and that phone delivers only a common "do-not-track" ID, preventing the marketers from establishing relationships between your specific phone ID and the ad.

      This intel will be used by the various campaigns in the next states to hold primaries to make sure "get out and vote for Hillary" messages are played on the NASCAR channel, and "get out and vote for Trump" booths appear at the Home and Garden Shows. While that's odious enough, the J.Edgar Hoover wannabees in the FBI will simply make use of the actual public voter registration lists. The more nefarious conspiracy-related schemes imagined will involve Joseph McCarthy clones in smoke-filled rooms, poring over data gathered from automated license plate readers, facial recognition cameras, IMSI catchers, and Bluetooth sniffers hidden around all the polling places.

    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.

    More to what I assume to be your point, the problem with the KKK isn't that their name is the Ku Klux Klan. It's that they're a bunch of racists and general bigots and they use violence and intimidation to attain their evil ends.. Plenty of violent racists/bigots both support Democrats and attain evil ends through violence and intimidation. The Black Panthers are an example of such a group. They hate white people, Jews, and Catholics. They're no better or worse than the KKK, who hates black people, Jews, and Catholics. And the Black Panthers were convicted of standing in front of polling places in Philadelphia in 2008 and scaring off white people who came to vote. Just like the KKK used to do to black people.

    It's not fair to say that every Democrat is a racist because the Black Panthers showed up at polling places to intimidate people into voting for a black guy who happened to be a Democrat*. In campaigns, the right to free speech overrides the right to free association, which means that shitty groups like the KKK or the Black Panthers or the Nazis or whoever are allowed to endorse candidates and parties even if the party or candidate doesn't want their name associated with the hate group.

    *It's also fair to say that President Obama probably agrees with THE NON-RACIST goals that the Black Panthers have, such as their economic goals. He would probably have their support even if he wasn't black. (If he gets the nomination, expect to see Bernie Sanders in a similar spot.)
