New Car Anti-Theft Device Profiles Your Rear End

Hugh Pickens writes "A car-seat identifier developed at Japan's Advanced Institute of Industrial Technology by Associate Professor Shigeomi Koshimizu can recognize a person by his or her rear end with 98 percent accuracy when the person takes a seat in his car. The bucket seat's lower section is lined with 360 pressure sensors that measure pressure on a scale from 0 to 256, sending information to a laptop, which aggregates the information, generates the key data and produces a precise map of the seated person's rear profile. Researchers say traditional biometric techniques such as iris scanners and fingerprint readers cause stress to people undergoing identity checks, while the simple act of getting seated carries less psychological baggage. Koshimizu wants to see his work available commercially as an anti-theft product in two to three years if automakers agree to collaborate. He sees possibilities of this device being used beyond auto-theft identity protection to a device for security identification in office settings, where users log on to their PCs as they sit down."

  1. Detect differences between full and empty load? by InterestingFella · · Score: 4, Interesting

    Some people apply their rear pressure differently based on if their rear load is full, empty or something in between. Not only does your overall weight change, but also the formation of rear pressing against the seat will be different, especially depending on your nutrition and different days. Is it going to be able to detect such load changes without many problems? Obviously there needs to be some kind of threshold, but if your rear pressure varies a lot the device could even lock you out from using your car.

      Assuming a random statistical distribution of failure, and a short "timeout" between tests, the overall system success rate of a 98% success on first try followed by 98% on second try means you'll only have to try a third 98% success trial something around once for each owner of the car, assuming you own a car "about 4 years" or so, and assuming I did the math in my head correctly for 2500 days. I figure every 125000 times you boot up the car, you'll need a 4th try, that's booting up the car twice a day for 171 years. So "lock out after 6 attempts" seems safe enough to only happen accidentally a couple times in the lifetime of the product run?

      Biggest problem is going to be embarrassment at having to get out of the car and try it again, if people see you doing that they're going to make all kinds of interesting assumptions about what happened to your rear last night, rough time doing doggie style or things are still too stretched out or sore back there today or whatever, so I'm thinking women would be waaaaaaay too embarrassed to buy one of these systems, even if it only happens once in a while.

    The scene: Aristocratic antique styled dining room. There's a long table to seat over 20 guests with a prominent chair at the head for the prime minister.

    You see various servants tidying up and leaving the room one by one while a butler inspects, he leaves last.

    *Ethan Hunt carefully drops down from the skylight suspended by a cable*

    *After much twisting acrobatics he replaces the seat cushion on the prime ministers chair with a pressure sensitive decoy unit* (For suspense let's put in a scene where he nearly knocks over a glass of red wine and catches the spilt drop with one hand while holding the glass with the other, a single drop of sweat will fall on a plate at this point, Ethan will wince as the drop lands but he won't have time to wipe the plate off)

    *He quickly lifts up just as the butler returns to the dining room, nudging the sensor into perfect alignment right as it leaves his reach*

    *Butler notices the drop of sweat and raises an eyebrow curiously, he then makes an icy stare at the servant girl who set that area as she enters the room, she looks fearful and guilty*

    *Cut to MI van parked outside, a 3D printer is printing out a faux-butt for Ethan to wear while he steals the prime minister's car, it is spraying a realistic flesh tone over the perfectly carved rear* (Insert witty joke from Luther about Ethan's butt, perhaps stating that he had to guess the color and hopes it's right)

    I believe almost all the accuracy from this device will be based on a single data point: weight. Weight is a good addition to a security system, it's already used in some areas, but thinking it can ID a person is silliness.

    The bucket seat's lower section is lined with 360 pressure sensors that measure pressure on a scale from 0 to 256, sending information to a laptop, which aggregates the information, generates the key data and produces a precise map of the seated person's rear profile.

    *emphasis mine*
    Fingerprint recognition works by creating an image of the print. This new method is no different, though the resolution is much, much lower and the area being examined is different.

    A person's weight is not evenly distributed across their cheeks. Even if it were then the shape and size of the crack differs from person to person; I'm not saying this is the be-all and end-all of arse recognition but it does illustrate the point that one might be able to differentiate between people by looking at their backsides.

    Use of a tow-truck to steal vehicles is not that commonly employed. Mostly owing to the amount of time that it takes to properly hook up a vehicle to a tow truck, the likelihood of discovery is exponentially higher. Although the action might appear innocuous to quite a few people, there is a huge risk of being questioned or even photographed, and a thief risks having to deal with both situations. Cars on private property can only be legitimately be towed with consent of the owner of the vehicle, or else by consent of the owner of the property, and proof of such authorization might be requested by someone who sees a car being hooked up. This is problematic for thieves who might want to employ such a technique... they are taking a 15 minute gamble that nobody who works there or sees them will care what they are doing. Finally, to discourage property owners from profiting from thefts on their own property, if a host of thefts from one particular place occur in too short a time, the owner of that place is probably going to be facing something just short of an inquisition to confirm that he or she is not somehow party to the thefts. In fact, I actually know one store owner who once was questioned about an unusual number of car thefts (not towed... just ordinary thefts) on his property, and he ended up having to invest in security cameras, which I had heard actually immediately made a differences in the number of car thefts happening there.

    So you have heard of a tow truck.
