Writing Style Fingerprint Tool Easily Fooled 96
Urchin writes "Some of the techniques used by literary detectives and courts of law to identify the authorship of text are easily fooled, say US researchers. They found that non-professional writers could hide their identity from 'stylometric' techniques by writing in the style of novelist Cormac McCarthy. Stylometric methods have been used in a number of high-profile legal cases in recent decades, including the 'Unabomber' trial. 'We would strongly suggest that courts examine their methods of stylometry against the possibility of adversarial attacks,' say the researchers."

how fast can you generate a text that (a) says what you intend and (b) does not point to you? Very fast, I'd wager.
as fast as: type it out, auto-translate it into french, auto-translate it back into: "the person who is being hated by myself is to be killed by myself by employment of the method of the bomb conflagration saving if it is the case that I am receiving the stipend of an amount that is one million of dollars. sandwich."

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.

Dear Sirs and Madam,
I wish to complain about that last complaint. I can assure you that all groomers of haddock and every other species in order Gadiformes are indeed transvestites. This is in fact a necessary grade to be reached in the apprenticeship process for the Gadiformes Groomers Guild (GGF). If the former complainant indeed knows of any non-transvestite groomers as such, then he should report them both to the GGF and to the Ministry of Fish Groomers in Luton at once!
Angrily,
Mr. Pint
