RFID, Biometrics and the flaws of both

RFID and biometrics are two of the most important features behind both the new passports and the new identity cards which we will be forced to have in the UK. They extend beyond just the UK though and they are being introduced the world over as an attempt to “crack down on terrorism” and “make transport quicker and safer”. I never really had a problem with ID cards on a civil liberties point (although I'm sure you're aware of the objections from that camp). What has been increasingly worrying me, on practical points, is the fact that it seems like they might actually make the job of killing people easier for terrorists and make us all less safe. The first I saw of this is from a Cambridge professor of maths who claims that if you use two methods of biometrics to attempt to verify someone's identity, where one is “stronger” than the other, the result is less sound. Basically; if you verified someone's identity by using their retina scan (strong) and a fingerprint scan (week) then the results on average would be less accurate than using just the retina scan… unfortunately there seems to be plans to use both to see who someone is.
The second, and perhaps more worrying of the two items that I saw on this topic over the last week has been the discovery that RFID chips (we have these in our library cards and they will be in the new passports/identity cards of a lot of countries) can be hacked from a distance AND can get viruses. The ability to hack means that (and this has been proven to work) is that if you are within 10 meters of someone you could download all the information from their passport and steal it. This information would be more than enough to steal their identity and then a significant amount of their money. On RFID being able to get a virus this might seem less worrying. It's not. What this means is that you could have your passport infected, at the same time as “they” are stealing your identity, and then whenever you used your card it could infect the machines and the databases it is used with. This becomes more worrying when you consider that airports are beginning to use RFID chips in order to let frequent flyers get through security faster “because they'd never be a terrorist”... A virus could be used to delete all the information on an airports computer system. Again this might not seem too big of a problem. The airport stops for a while whilst the backups are run and then it all starts again. But if someone wrote a virus that made the RFID chip think that the person called, say, “John Smith” wasn't a terrorist, when he was, he would be able to walk through the security checks far easier and be on his way to killing thousands of people… all this because the government is trying to make us “more safe”... shurely shome mishtake?

The Golden Rule

Coin collecting is somewhat of a hobby of mine. I've been doing it a little while now and am specialising in hammered coinage of England. As I have previously written about in other places there is perhaps one golden rule which stands out more than any other on the subject of coin collecting and it is this: don't clean them. Ever. Perhaps the previous sentence was a little zealous there, obviously if you have just dug it up then use clean, cool water to wash off excess dirt, but nothing else. Today I decided to break that rule, taking a Henry III voided long cross penny and giving it a jolly good go at cleaning it. After this I have discovered that the golden rule is golden for a reason… it is a good one. Anyway, after spending a long time using some soft kitchen roll and cold water I decided to have a go with the big guns. Cilit Bang and hot water. This may sound stupid and I know that a copper coin would clean differently to a solid silver on; but I thought I'd press on. Cilit Bang didn't seem to do anything, the heavy black coating on the coin remained and not a lot changed. Hot water was my next weapon, and this produced a rather unexpected result. It did clean some of the dirt off, but it also gave the silver a “burnt” look. Perhaps this was due to the rapid oxidisation caused when it was brought out of the water due to the heated silver, perhaps it was due to the Cilit Bang which might have still been working its way through. I don't know. Still the situation seemed a little bleak, although the rest of the silver had taken on a somewhat nice golden hue, so its not all bad. I decided to leave it there and left it to dry. When checking back on it dry and moving it to be with the rest of my collection it did seem to have got a little better, perhaps that was just the worse light. Either way, I now can state 100% that the golden rule is a good one… in the future I might follow my own advice.

AJAX Write 0.9

Writing about web page

I recently discovered a new program called AJAX Write. Cunningly enough this uses AJAX. The general idea is that they wanted to create an alternative to Microsoft office which would be usable by anyone at any time over the Internet. They seem to have done a fairly good job with it, it can apparently open a variety of file types; .odt, .pdf .txt rich text format which gives it a good sense of functionality. It doesn't seem to have a spell-check function, which is a shame, nor does it seem to have a grammar checker. All in all, it is only a 0.9 release, and I hope that it can have a good long life. They are going to be releasing a new program every Wednesday which is aimed at rivalling “Office”. I would like to see a conjunction with open office though to try and make the open document type a new standard; but I doubt I'll get that. Currently I am struggling to make the save function work though…

Opening time: approx. 6 seconds
Size: 400k
Cost: FREE! (free beer – for all you /.'ers)
also, you never need to update it… which is nice
