I've always wondered just how accurate signatures are. I've noticed that my own signature varies widely depending on various factors.
Signatures written on paper are not all that helpful for a few reasons. First off, they are easy to forge. Second off, a single person might sign his name twice and produce two signatures which look very different to both the naked eye and some forms of analysis - hence not accurate. Where they actually are accurate, however, is when written on pressure sensative pads (such as those seen on new-fandangled credit card swipers). If you were to do an analysis of the pressure and speed at which the signer signed various parts of the signature, you would actually produce some very reliable information. This is because even when you sign your name in slightly different manners you have the tendancy to use the same speed/pressure on certain parts of certain letters. Personally I would just use digital signatures...but calculating hash functions on the back of your resteraunt receipt is never fun. Its also difficult to fit a 256-bit output on that miniscule "sign here" line.
Taking your kid to the park while intoxicated is just not right.
I agree. At least let the kid sober up first.
The only problem with this is that you aren't going to get a few "private minutes" with the machine
I am a student at Princeton and last term I took Ed Felton's class on Security. (Ed Felton being one of the authors). This was one of the issues which he talked about. I can't speak for the State of New York, but in New Jersey the voting machines are often stored at the voting sites over night. These voting sites are more often than not, unsecured places such as Churches or Schools. Prof. Felton, on the night before an election, went to all of the election sights. A distrubing number of electronic voting machines were stored in hallways or behind unlocked doors. He has an entire slide show of pictures which he took of these machines the night before an election. Had he any malicious intentions, he could have easily tampered with the machines. I'm sure that most of the election officials are very trust worthy. It is not them who concerns me. It is the fact that anyone can simply walk into a church basement and have access to all of the voting machines for that district.
I'm quite sure a wild big cat or wolf raised carefully in captivity would do just as well as their domesticated cousins, and there is reason to believe they may do better.
Well I think garnkelflax addressed this earlier:
I watched a program on Animal Planet a few years ago where they ran tests on wolves. They determined that wolves had no desire to 'please' (utilize) humans regardless of whether they were raised from pups or not.
