Wifi Could Be Used To Detect Guns and Bombs, Researchers Say (bbc.co.uk) 32
An anonymous reader quotes the BBC:
Ordinary wi-fi could be used to detect weapons and explosives in public places, according to a study led by the Rutgers University in New Jersey. Wireless signals can penetrate bags to measure the dimensions of metal objects or estimate the volume of liquids, researchers claim. Initial tests appeared to show that the system was at least 95% accurate.
It could provide a low-cost alternative to airport-style security, researchers said. The system works by analysing what happens when wireless signals penetrate and bounce off objects and materials.

No, it's more like a wife router or penis M&M's. Freaking autocomplete.

If your microwave oven can screw with your 2.4GHZ wifi, I'm pretty sure you can easily defeat this "special" detection method.
Metal detectors don't work all that well for plastic weapons, or ceramic knives either. Unless you have the detector set to belt buckle and coins in the pocket mode.

Well, having a sense of humour, I could point out that flying exposes you to greater radiation http://jag.cami.jccbi.gov/cari... [jccbi.gov], for those interested in numbers. So to protect yourself, you can claim health justification for a tinfoil hat and suit, to block radiation, so, hmm. You know it;s coming, they don't like the way you looked at them, strip search and fist up the arse to find contraband, no just torturing you to feed their sexual perversions.

So will the CSIRO be able to collect licencing fees from body scanners now?
