Aussie Speed Cameras in Doubt Because of MD5

An anonymous reader writes "A speeding case has been thrown out in Australia after the Roads and Traffic Authority admitted that it could not prove the integrity of speed-camera photos. 'The case revolved around the integrity of a mathematical MD5 algorithm published on each picture and used as a security measure to prove pictures have not been doctored after they have been taken.'" I wonder if Australian police are as (radar gun) trigger happy as they are in certain parts of the U.S.

      Hmmm, i've gotten very few traffic tickets in my life in washington... and there are areas that I make damn sure to speed +10mph over and +20mph over.

      the first time I got a ticket was when I was younger and going really +85 in a 55, and got a ticket for going 10 over. I didn't argue that one. I got another ticket for going 10 over in a small town.... it was inbetween a 30mph zone and a 45mph zone... The cop did in all fairness see a sign that said 30 from his angle of view, where I saw a sign "slow down speed zone ahead". The judge threw that out.

      All the other times i've been pulled over have been for trivial offences such as a tail light being out, my license plates lights being out, failure to signal/turn signal light being out. Not that I don't replace those bulbs or anything, guess they only last a few years. One case right on red with sign... the sign was confusing as it was a 5 lane intersection, but there was a sign and I knew better.

      Pulled over once because I put my year sticker in the "wrong" spot 10 days before my tabs were do... cop in all honesty thought they were expired. I explained that I put them there cause my year stack was full. He told me I need to get in there with a razor blade. I explained in friendly terms that I broke the razor and you could still see it sticking out of my year tabs. He just said "oh".

      So three moving violations in my life, one thrown out, one paid in full, one midigated. One I feel was unjustified, one totally 100% justified, and one I just saw the judge to prove I had insurance and got a big discount for saying hello and not wasting his time.

      The answer is: any speed other than the one all the other vehicles are moving at.

      Numerous studies have shown that the most important factor in reducing the total number of accidents on highways is to get all of the vehicles moving at about the same speed. Driving the speed limit when everyone else is going 10 over is dangerous. Driving 10mph faster than everyone else is dangerous.

      Higher absolute speed increases the severity of injuries in case of an accident, different roadways also impose a natural maximum (though the US Interstates were mostly designed for 80mph traffic, since the speed limit was 70mph when they were constructed), and weather conditions can change things dramatically, but the most important consideration in minimizing accidents is getting all of the cars moving at close to the same speed.

If you're the punk passing everyone and weaving through traffic, you're a hazard, even if your car is perfectly capable of handling the speed on that road.

Later he mentioned how nobody seems to speed, and he had been flying past all of them. He also mentioned seeing yellow boxes all over the place on the side of the road. He just assumed they were emergency telephones or something. A couple of months later, a bill from the rental company showed up on his credit card for $3,000US. He called the rental company to ask them about it, and they said the car had been issued 35 speeding tickets on the weekend he had rented the car. It was then that he realized that the yellow boxes were cameras. Expensive lesson.

      There are some circumstances where speeding is simply not acceptable, such as residential areas. However, most interstate highways (in the US anyway) are easily traversable at speeds in excess of 100, with a few exceptions. Driving fast is not, in and of itself, a cause of crashes. In Germany, for example, traffic fatalities in 2004 were 7.1 per 100,000. Meanwhile, with our "life saving" speed limits in the US, our traffic fatalities in 2003 (most recent data) were more than double that at 14.66 per 100,000. Clearly it's possible for people to drive fast without a higher number of fatalities.

      Driving is an inherently risky activity, and it's impossible to remove all human error without removing humans. I just don't believe that speed limits are much more than an inconvenience and a cycle of tickets funding enforcement and government. If there are more accidents when people are speeding, I believe it's because they haven't had proper training; speed limits don't generally let anyone come close to approaching the limits of their vehicles' abilities, and it gives people the illusion that they can make any turn at any speed and stop on a dime. Furthermore, people tend to focus more when driving faster because they don't get lulled by the relaxing pace of 55MPH. People who are reckless will be reckless regardless of the law; it's just an inconvenience for the rest of us. But that's just my opinion.

      Bogus physics here. The fuel efficiency depends on the engine RPM (where it has an optimum range)and the speed of the vehicle (more -> worse efficency). If the manufacturer says the car is "most efficient" at 65 mph, they mean that it is the best compromise between fuel efficiency and time needed to travel. If you go 30 mph while maintaining the same engine RPM by switching to the appropriate gear, then the very same care will be more fuel efficient, period.

No, it is exactly the other way around: A car with a "real" automatic transmission (the ones with a torque converter instead of a clutch) is less efficient because it is heavier (about 50 kg) and because the torque converter acutally has significant slipping (~1-3%) since torque is transferred by a liquid medium (unless the vehicle also has a torque converter clutch).

    2. send bill to speeder (possibly including hash of picture or in some way "committing" to that particular md5sum)
    Then, the problem the bad guy has is to find another picture with that same hash value. This is a preimage attack [find another photo that outputs this hash value] and the weaknesses in MD5 were collision weaknesses: particular collisions found and an algorithm for generating collisions. But collisions are just two messages that have the same hash value, not a particular hash value of your choosing.

    If the protocol doesn't have a way to securely associate a hash with a photo (e.g. doesn't sign it), then it doesn't make a difference if you're using MD5 or SHA-1 or SHA-256, the cops can still just doctor photos at will and only produce the hashes of the doctored photos. So this line of "attack" has nothing to do with underlying cryptographic weaknesses.

    In the case of speed limits, traffic engineers have known for quite a while that the safest speed limit for a given road is the 85-percentile speed - the speed that 85% of the traffic travels on that road. It's not speed that kills, it's speed differential, and having slow drivers on fast roads is just as dangerous, if not more, than having fast drivers on slow roads. Setting speed limits to arbitrarily low values will result in a small percentage of drivers obeying them, and those drivers will present a significant hazard to people traveling at reasonable speeds for that road.

    The fact is that raising or lowering speed limits has very little to do with how fast traffic moves. Here, look:

    # Speed limits were posted, on average, between 5 and 16 mi/h (8 and 26 km/h) below the 85th percentile speed.

    # Lowering speed limits by 5, 10, 15, or 20 mi/h (8, 16, 24, or 26 km/h) at the study sites had a minor effect on vehicle speeds. Posting lower speed limits does not decrease motorist's speeds.

    # Raising speed limits by 5, 10, or 15 mi/h (8, 16, or 25 km/h) at the rural and urban sites had a minor effect on vehicle speeds. In other words, an increase in the posted speed limit did not create a corresponding increase in vehicle speeds.

    # The average change in any of the percentile speeds at the experimental sites was less than 1.5 mi/h (2.4 m/h), regardless of whether the speed limit was raised or lowered.

    # Where speed limits were lowered, an examination of speed distribution indicated the slowest drivers (1st percentile) increased their speed approximately 1 mi/h (1/6 km/h). There were no changes on the high-speed drivers (99th percentile)

    # At sites where speed limits were raised, there was an increase of less than 1.5 mi/h (2.4 km/h) for drivers traveling at and below the 75th percentile speed. When the posted limits were raised by 10 and 15 mi/h (16 and 24 km/h), there was a small decrease in the 99th percentile speed.

    # Raising speed limits in the region of the 85th percentile speed has an extremely beneficial effect on drivers complying with the posted speed limits.

    # Lowering speed limits in the 33rd percentile speed (the average percentile that speed were posted in this study) provides a noncompliance rate of approximately 67 percent.

    # After speed limits were altered at the experimental sites, less than one-half of the drivers complied with the new posed limits.

    # Only minor changes in vehicles following as headways less than 2s were found at the experimental sites.

    # Accidents at the 58 experimental sites where speed limits were lowered increased by 5.4 percent. The level of confidence of this estimate is 44 percent. The 95 percent confidence limits for this estimate ranges from a reduction in accidents of 11 percent to an increase of 26 percent.

    # Accidents at the 41 experimental sites where speed limits were raised decreased by 6.7 percent. The level of confidence of this estimate in 59 percent. The 95 percent confidence limits for this estimate ranges from a reduction in accidents of 21 percent to an increase of 10 percent.

    # Lowering speed limits more than 5 mi/h (8 km/h) below the 85th percentile speed of traffic did not reduce accidents.


    The time to worry about traffic safety is when you're designing and building the road, not when you feel like monkeying around with speed limits. If you see a speed limit set lower than the 85% percentile speed, it's set that way so that the state can make money, not to make anyone safer.
