    Why is the former impossible? Geometrically, two objects could be in different (but congruent) elliptical orbits. They would have the same period but follow different paths and approach the star at different times -- or maybe even at the same time.

  2. Support every type of repeating event. on What Would Your Dream Calendar Program Look Like? · · Score: 1

  3. Signature analogy is valid on More On The SDMI Crack & Why Digital Sigs Are Not · · Score: 1

    I respect Bruce Schneier, but he blew this one. His assertions about how digital signatures are not like signatures are incorrect; the same flaws he posits for digital signatures exist for physical signatures.

    For example, he says "a signature serves to indicate agreement to, or at least acknowledgment of, the document signed. When a judge sees a paper document signed by Alice, he knows that Alice held the document in her hands, and has reason to believe that Alice read and agreed to the words on the document." That's false. I have seen people sign a document in front of a notary public when the document was almost completely covered by a blank sheet of paper except for the space they were signing. The document was my will, and the signers were witnessing it. Their signatures don't indicate agreement; they are just evidence that that piece of paper is the one I also signed as my will. Their signatures do not acknowledge the document; they would never be able to testify in court that the document is one they saw -- only that the paper is paper they saw. (The document is also the message.)

    He also says a digital signature does not authenticate a link between the computer (which he admits is linked to the document) and the purported signer. Well, hey, don't give away your secret key or your passphrase. A judge only knows a signature on a piece of paper means the person indicates agreement to the contract (if that is what it is) because people are taught that that is what signatures mean. There is nothing in the laws of nature that gives signatures that meaning, and people aren't born knowing it. It is a convention; it is taught. So teach people their secret key means the same thing. The analogy holds.

    Schneier also says the link between the document and the person may be broken because a rogue version of PGP that looks like the real thing could transmit your secret key. But real world documents can be forged too. It's easier to get people's signatures for copying than it is to write and disseminate a rogue version of PGP, or to obtain their secret keys otherwise. The analogy holds.

    Yes, we should be mindful of the foibles of digital signatures. But we should not hold them in less esteem than physical signatures.

    Well, you've told us your opinion, but why should we value it? A police officer's uncontradicted testimony is fine evidence for a misdemeanor conviction. That's very routine in all sorts of minor court cases, and it is proper. In cases where a police officer is wrong, the defendant is free to get on the stand and say so, and a solid citizen (somebody who shows the jury they are credible and competent) may well be able to outweigh a police officer's testimony in the jury's mind, particularly if they explain a mistake the officer made or how he jumped to a conclusion.

  9. Voting is more difficult on eLection '04 · · Score: 1

    The proposal in Slashdot's story has major flaws. The biggest flaw is there's no proof of how people voted. So the machine says it got 739 votes for Mr. Smith. How do voters know that's true? We trust the programmer? Nobody snuck a new PROM into the machine?

    Paper ballots can be counted and recounted. You can go at the beginning of the day and see the box starts empty. You can watch during the day and see that only ballots given at the registration desk are put into it. You can watch them open up and count it at the end of the day.

    Those machines with the levers are a little more difficult to authenticate, but, because they are mechanical, they are also hard to alter in ways that cannot be detected. They don't have a complicated invisible program that only the engineers understand.

    Bottom line: The voting system has to include a method of proving that as many people voted for Mr. Smith as the system says. Touch screens don't do it.

    Electronic solutions are still possible. The voter registrar could give each voter a cryptographic token. The cryptographic token can be anonymized without interfering with its authentification. (E.g., Chaum's digital money which can still be authenticated as issued by a particular bank without any sign of which customer it was given to.) That token can then be given, anonymously, not to central machine but to a candidate or their agent. Then the candidate can register the token with the government agent who counts votes.

    Because the candidate receives vote tokens from the voters, the candidate knows, and can prove, how many votes they got. The government agent should publish the list of vote tokens, so anybody who wants to can verify each one bears the authentication of the voter registrar, proving there were no extra votes. Every voter knows their vote counted because they gave it to the candidate they chose.

    There must still be control of how the registrar gives out tokens. This corresponds not to the voter registration process at the town hall, but to the registration desk at the voting place. Any person who chooses must be allowed to watch all the tokens being given out -- they must be allowed to see each token is given to a person who proves their eligibility to vote (residence, et cetera).

    When this is done right, the public will know only people who were entitled to vote voted, that every vote cast was counted, and that no votes not cast by an eligible voter were counted.

    I'm sure I'm missing a few points, but that only demonstrates how difficult proper voting is.

    "And just what do they get if they win their lawsuit?"

    If you start by assuming there is a reason for suing an unknown party, your reasoning is likely to achieve better results than maligning somebody in ignorance.

    After one sues an unknown party, the plaintiff then subpoenas documents and deposes witnesses. This may include motions asking the court to compel production and testimony. The purpose is to discover the identity of the defendant. E.g., one might get the court to order various government officials to tell who is running Echelon, or one might order a landlord to identify their tenant or a supplier to identify their customer.

    After the plaintiff discovers the defendant's identity, they file a motion to amend the complaint and an amended complaint that names the defendant. Then the suit proceeds as any other, with the possibility for injunctions, compensation, punitive damages, et cetera.

  17. Insurance = standard deviation reduction on UK Allows Insurers To Use Genetic Test Results · · Score: 3

    Those replies saying insurance exists to spread risk across a population are missing an important factor. The purpose of insurance is not, and cannot be, to distribute the mean cost of an event (health problems, fire, flood, whatever) over a population. I explained why in another post, but I will do it here with a more mathematical orientation. The purpose of insurance is to reduce the standard deviation of cost of an event in a population without changing the mean cost for each individual.

    Suppose two (or more) people are situated with a probability distribution of various costs occurring -- their house might be flood or struct by lightening, or whatever. Their costs in a particular year may be 99.9% of being zero and .1% of being $100,000 (just for illustration). Mean cost: $100. Standard deviation: $3,160. If they form a contract that each will share the costs, then when one house burns down, they each pay half. If both burn down, nothing has been accomplished, but suppose they live in different areas so floods occur simultaneously only by chance. Mean cost: $100. Standard deviation: $2,235. The mean is still the same because the chances of damages have not changed. The standard deviation is lower because they are sharing.

    With two people, the standard deviation is 70.7% of its previous value (1/sqrt(2)). Do it with a million people, and the standard deviation drops to .1% of its previous value -- $3 a year. Insurance reduces the standard deviation. It does not alter the mean, except to increase it for the costs of administration and profit.

    When you try to spread the risk among differently situation people with different means, the insurance model breaks. If Pat lived inland with a .1% chance of flooding per year and Chris lived on the beach with a 1% chance of flooding per year, and they agree to share the risks, then Pat's mean jumps from $100 to $550. Pat won't take that deal!

    Of course, you could fix this by sharing the risk at 1:10 for Pat:Chris -- Pat pays 1/11 of any damages that occur, and Chris pays 10/11. Then Pat's mean stays unchanged -- but so does Chris's. So you haven't saved Chris any money on average. Pat, and people generally, will happily buy insurance if it reduces their standard deviation -- but not if it increases their mean greatly. So you can only sell insurance to people when it does not change their mean cost by more than they value the reduction in standard deviation.

  18. What are the alternatives? on UK Allows Insurers To Use Genetic Test Results · · Score: 1

    Considering what will happen to consumers if insurers are permitted to discriminate based on genetic testing is only half the issue. Suppose discrimination is prohibited. What happens in the insurance trade then?

    First, people who learn they have Huntingdon's Cholera become more likely than average to purchase insurance, because it is a much better deal for them. They know their costs will be high, but they only have to pay the average price, which may be much lower than their costs.

    Second, insurance companies raise their rates to make up for their increased costs. Then this is repeated for Alzheimer's, cancer, et cetera. Every disease that can be tested causes another pool of people who learn they have that disease to become more likely to buy insurance at a bargain rate. Every time they do, the price goes up for everybody.

    You may think that is fine so far, that everybody will have to pay more to help out the people who were unfortunate. But there is another problem. If all the increases necessitated by people with diseases (present or probable) raise the price of insurance above its value to the average healthy person, then the average healthy person will not buy insurance. In other words, if the price goes above what a healthy person can expect to pay for health care on average, plus some additional money for the value of knowing they are covered in case of catastrophe, then health insurance becomes a bad deal for a healthy person. They will not pay too much for it.

    Once that happens, healthy people drop out of the insurance pool. Customers who paid a lot and cost little leave, and the insurers lose money. Prices have to rise again. Then it becomes a cycle that cannot be stopped. People in the pool who have less expensive diseases than others will find they are paying more for insurance than they will have to pay for health care, so they drop out too.

    I am not sure there is a solution for that. If insurer and insured agreed upon a price before genetic testing were performed and committed to a permanent contract, this problem wouldn't occur. But you can't bind customers to a permanent contract, because society just wouldn't accept it. Not in a private contract, anyway, although the government form, socialism, hasn't entirely been rejected. But that has its own problems.

Even if it were, there are approximations that yield the same general behavior with little processing power. For example, here's an approach that uses only one queue: Send each packet only if it bids at least the current threshold, otherwise leave it in the queue. Once a time slice, change the threshold to the lowest bid sent in the previous time slice.

  22. Packet bidding on Why Not To Meter Internet Access · · Score: 3

    There are good ways to charge for service rendered, and we need them so long as there is network congestion. One proposal I saw years ago (sorry, too long, no pointer) is that each packet carry a bid indicating how much the sender will pay to have it sent. In each time slice, routers transmit the highest-bid packets and bill them all at the rate of the lowest bid transmitted. (Billing is accumulated and done in per-day chunks or something, not with additional packets.)

    A user would have some way of adjusting their bids, maybe telling email clients to bid nothing and telling their video streaming to bid 10 cents per megabyte. The email would go through eventually, which is fine, and the video streaming would work without annoying pauses -- or the user would choose to increase their bid to make it so, to suffer with the pauses, or to watch the video later, when network demand is off peak.

    There are other details -- packets coming back from servers might be billed to the requestor according to some token, or maybe they would be billed to the server, who would balance the charge by revenue in their own way -- ads, merchandise sold, charges to the web viewer, whatever.

    I liked the proposal when I saw it. I'm certainly happy paying a flat rate for unmetered service, and maybe I'd continuing bidding zero for my packets most of the time. But it would be nice to have the means to get some things faster when I wanted to, and it is entirely reasonable that people who want better service should pay for it. If you want to know what you're going to pay, you could set all your bids to zero, or software could help you estimate what to bid to match your budget -- and could adjust those bids as you accumulated charges to ensure that you stayed under budget.

    Note that when the network is not congested, packets are transmitted for free, even the highest-bid packets, because the router is able to transmit all requested packets in each time slice. So this system is really asking the people who want extra capacity the most to pay for it.
