Metadata On How You Drive Also Reveals Where You Drive 81

chicksdaddy writes "Pay-as-you-drive programs are all the rage in the auto insurance industry. The (voluntary) programs, like Progressive Insurance's Snapshot use onboard monitoring devices to track information like the speed of the automobile, sudden stops, distance traveled and so on. Safe and infrequent drivers might see their rates drop while customers who log thousands of miles behind the wheel and/or drive recklessly would see their insurance rates rise. GPS data isn't generally collected, and insurance companies promise customers that they're not tracking their movement. No matter. A study (PDF) by researchers at the University of Denver claims that the destination of a journey can be derived by combining knowledge of the trip's origin with the metrics collected by the 'pay-as-you-drive' device. The data points collected by these remote sensing devices are what the researchers call 'quasi-identifiers' – attributes that are 'non-identifying by themselves, but can be used to unique identify individuals when used in combination with other data.' In one example, researchers used a strategy they called 'stop-point matching,' to compare the pattern of vehicle stop points from a known origin with various route options. They found that in areas with irregular street layouts (i.e. 'not Manhattan'), the pattern will be more or less unique for any location. The study raises important data privacy questions for the (many) 'pay-as-you-drive' programs now being piloted, or offered to drivers – not to mention other programs that seek to match remote sensors and realtime monitoring with products and services."

    The war for Internet privacy is over. We lost. There is no set of laws or regulations or RFCs that can get it back. Too much of the world's economy now depends on getting and analyzing and cross-referencing petabytes of information on consumers and their daily activities, phone calls, emails, television viewing, purchases and web surfing. And now, they all have the technology to do it in an economical fashion.

    As Scott McNealy said way back in 1998, "You have zero privacy now. Get over it."

    • The war for Internet privacy is over.

      Actually, not even Internet can compromise your OTP lines of communication. You can still have privacy when you need it most.

      • not even Internet can compromise your OTP lines of communication

        Even perfect encryption still allows traffic analysis. If the government can discover with whom you're communicating, when, where, and how much, it can discover much about your motives.

        • Traffic analysis only gives you an upper bound. That's why spy stations read numbers every day, even though they (likely) only rarely send messages.
      • Actually, not even Internet can compromise your OTP lines of communication.

        Yes it can. A OTP can protect the content of your communication, but it does not protect the meta-data. "They" can still see who you are talking to. Once they know who is involved, they can use the proverbial $5 wrench [xkcd.com] to retrieve the content.

        • Actually, they can't if you implement it properly. Given the nature of OTP, it's perfectly safe to use broadcast/multicast to transmit the messages. Or propagate them in a peer-to-peer graph of nodes. Or you can use a bulletin board-style system to connect a large number of people. Unless your system is actually compromised, there's no way to tell which recipients succeed in decoding which messages.

      Implications of robot drivers:
      - no need for each person to own a car. A pool of robot "taxis" will be available to everyone at all times. Dispatched from one company there will be no turf wars, no gouging of passengers, no navigational incompetence. - no need for taxi drivers, truck drivers, ambulance drivers, etc.
      - no need for parking enforcement & traffic cops
      - no need for human-use gas stations
      - no need for Joe's Rip-Off garages
      - no need for Costco to sell motor oil
      - and best of all, a 95% reduction in TV advertisements!

If there is anything to be afraid of it is that we have big data and not huge data. The false positives of big data are manifest in huge data, when supposedly unique results reutinely yield multiple, instead of only one false positive. 100 years ago we liv

      Actually, I am fine with Holmes. He uses his abilities to track down worthwhile criminals and bring them to justice. he doesn't waste his talent on harassing basically harmless low level offenders and he certainly doesn't waste it trying to get people to buy things they don't need and that are in many cases ultimately harmful to them.

      If only the corporate world had that level of moral restraint.

      It was soon obvious that the feats of deduction based on observation described in the books were explained to the reader post-seeum, that is, explained by Holmes himself and the reader was not even invited to participate. Or Doyle was too simply lazy to describe the surroundings, opting instead for some sort of empty exercise in hero-worship.

    Throughout history and especially in today's world anyone able to pay extra can get more privacy and anyone sufficiently poor has none. This is simply a continuation of that trend. The poorer you are the more forms you have to fill out with personal information to get what you need and the less likely those forms are to be jealously guarded. On the extreme end you have people filling out dozens of forms daily dealing with hospitals, charity organizations, food banks, and government assistance organizations just to survive. In this case if you're rich enough you can choose an insurance company that won't log every mile you travel. At the other extreme you have people with private airplanes they board with the surrounding areas screened for photographers; houses surrounded by tall walls and guards; every form filled out by someone else and when possible with inaccurate personal information; cars with dark tint on the back windows; and personal physicians bound to secrecy with highly restrictive privacy agreements.

    by Okian Warrior ( 537106 ) on Saturday September 28, 2013 @12:50PM (#44980059) Homepage Journal

    The reason for insurance is to spread the risk (and associated costs) over a large population.

    When insurance companies pick-and-choose their customers and rates, it invalidates this purpose.

    We've been seeing this with health insurance in past decades: ineligible if you have a pre-existing condition, or get dropped if you develop a condition, or get charged more for smoking or being older.

    This makes sense from a business perspective, so don't bother saying "what did you expect a business to do?" I'm saying that it makes progressively less sense from the customer's point of view. As these metrics get better, the companies will know exactly how much you will cost them as a customer, and charge the appropriate rates. Why bother with insurance if they know beforehand how much you will need it?

    Legally mandated insurance then becomes simple rent-seeking, with no benefit to the consumer.

    This particular trend - monitoring the driver's behaviour - is framed as a good idea. Everybody thinks they are a better-than-average driver, so the tradeoff seems like a good deal. You don't care about the big picture because hey! I just saved a bundle on my car insurance!

    Here's the big picture: there's no way to verify that the monitoring unit isn't broken, there's no way to verify that the monitoring report is accurate, or that what it's measuring is significant, or that the company isn't skewing the risk. There's no studies that link measured modes with accident risk, no way to tell whether the algorithm for detecting driving modes has flaws, no leeway for corner cases or exceptional conditions, and no way to appeal the decision.

    You have a promise from the insurance company that, if you're a safe driver, your rates will go down.

    The privacy implications are also important: your driving profile probably tells a great deal about your psychological makeup (how often you use the horn, how sharply you take corners). This would be of enormous benefit to advertisers, profilers, police, and national security agencies. The insurance company can make money by selling this information, but it's OK because it's not financial information.

    Ten years from now this will be a problem: insurance companies siphoning money from customers for no benefit.

    Perhaps we should be forward-looking this time and prevent useless suffering before it happens.

    • "You have a promise from the insurance company that, if you're a safe driver, your rates will go down."

      I hope you don't actually believe this. They said the same thing when airbags were invented. They said the same thing when daytime driving lights became mandatory, and the seat belt laws too. You would think my rates would be almost zero by now. Nope.

      You've gone completely to the opposite extreme from the one the insurance companies are trying to get to.

      There are two types factors at play here: Luck (randomness), and various behaviors under your control.

      Insurance is for distributing the cost of bad luck over the entire population. People agree that anyone could, randomly and through no fault of their own, get cancer or get hit by a drunk driver. And while the cost of dealing with the aftermath may be exorbitant for an individual, it's reasonable if a bunch of people get together and agree to cover the costs together for anyone in the group who happens to be unlucky.

      Insurance is not for distributing the cost of risky behaviors that an individual willingly engages in. In health insurance, it makes no sense to require non-smokers to cover the extra cost smokers incur due to the additional health risks caused by smoking. Likewise, if you choose to speed or make a lot of sharp turns, it makes no sense to force safer drivers to subsidize the cost of your risky behavior.

      The insurance industry would like to go to one extreme and drop coverage or deny claims for people suffering from bad luck. You want the other extreme where insurance covers everything including willingly partaking in risky behavior. The logical balance is to force insurance companies to cover bad luck cases, while allowing them to distinguish and assign different rates based on riskiness of behavior. (Note that this also "solves" the DNA profiling problem. You do not control your DNA, so any problems you're genetically predisposed to are due to bad luck, and should be covered.)

      Ten years from now this will be a problem: insurance companies siphoning money from customers for no benefit.

      In states which require auto insurance, there is usually a government insurance commission which limits the amount of profit the insurance companies can make. They cannot siphon off additional money. If they get into that situation, the state will force them to reduce rates to bring their profit margin back down.

      Or at least that's what's supposed to happen. If that's not happening in your state, you need to figure out why (usually it's due to corruption because politicians know they'll always be re-elected because the state always votes for one particular party), and do something to fix it. The mechanism for regulating insurance rates is already in place for most people, no need to complain as if we're completely at the insurance companies' mercy.

        There's a huge difference between risk factors you know in advance and having bad luck later. Would you let someone diagnosed with cancer take out a life insurance policy at the same rate as everyone else? No. Would you let someone who's been to a genetic review and found he has a 99% predisposition for developing cancer in the next five years take out a life insurance policy at the same rate as everyone else? Yes, it's bad luck. But he knows he has bad luck and can now hike his payout and pool his crap odd

      The problem is that fundamentally insurance is not a good fit for the requirements of health care.

      Insurance for a business or consumer provides protection in the event of catastrophic but exceeding rare events, generally events so rare that the probabilities defeat the human imagination and most people are unable to make realistic judgements about them.

      That's part of it - the Sesame Street version. The other part is to limit risk and costs to subscribed population.
