Japanese teen smokers hack age verification with bank-notes

2 Comments

Tokyo vending machinesEverything can and will be hacked; once you have the motivation sussed, the exploits will be close behind.

Point in case: Japanese cigarette vending machines have age-verification cameras fitted to them to prevent teens from illegally purchasing tobacco. A great idea, and a typically Japanese high-tech fix for a social problem, right? [image by midorisyu]

Well, it might have been – if the kids hadn’t sussed out that the cameras can be fooled by not just pictures from magazines but the portraits of historical figures on bank-notes. Back to the drawing board – I wouldn’t want to be on the R&D team of the company that makes those vending machines right now.

I know where you drove last summer – the secrets your satnav could tell

1 Comment

Super-seekrit satnavHappy Independence Day, America! I expect you’ll be busy making loud noises with explosives and generally partying it up this weekend, and I don’t begrudge you that*. But here’s some advice – if at some point you should decide to take a little drive somewhere to do something you maybe shouldn’t do, turn off the TomTom. [LOLnav based on an image by pizzodisevo]

You see, it turns out that not only does your satnav tell you how to get from A to B, it remembers where A and B were, when you travelled between them, and where you drove through on the way. Plus, if you’ve linked your phone to it via Bluetooth, it’ll have a record of every call and text message you made during the journey.

This isn’t a standard feature, obviously; it takes a detective with some good tech sk1llz0rz to tease out the old files, and now this has been revealed (by the superbly-monikered Beverly Nutter of London’s Metropolitan Police, no less) we can expect the same hacker enthusiasts who found the vulnerabilities to find a way of closing them.

So, just another front-line skirmish in the of the war between technology and privacy … but then if you’re doing nothing wrong, you have nothing to fear, right?

[ * Actually, I do kinda begrudge you it; the closest we Brits have to Independence Day is Guy Fawkes Night. I’ve always clung to the explanation for burning Fawkes in effigy that a slightly inebriated friend of my father’s told me when I was about twelve: “We’re not burning him for trying to blow up the government, Paul; we’re burning him because he failed.” Happy 4th July! ]

‘Ghost’ Photos through Quantum Physics

30 Comments

toysoldierScientists funded by the Air Force have used quantum entanglement — in which pairs of particles continue to interact even after they are spatially separated — to snap this picture of a tin solider without aiming a camera directly at the object.  The technique, called “ghost imaging,” has potential military or space applications, such as using aerial drones to survey of battlefields obscured by clouds, or the smoke that follows airstrikes.  Yanhua Shih, who has been experimenting with entangled photons since 1995, says:

“…[T]he image is not formed from light that hits the object and bounces back. The camera collects photons from the light sources that did not hit the object, but are paired through a quantum effect with others that did. An image of the toy begins to appear after approximately a thousand pairs of photons are recorded.”

These are exciting times on the frontiers of physics. Researchers in Copenhagen took a step towards producing a quantum bit. And scientists at Arizona State are trying to figure out how electrons interact. Both are necessary steps towards building superfast quantum computers.

Question Surveillance, Go to Jail

2 Comments

london-cameraNormally I’d leave surveillance-outrage stories to BoingBoing, but really:

Four young residents of a North Philadelphia house who circulated petitions questioning police-surveillance cameras were rousted from their home Friday and detained 12 hours without charges while police searched their house…. 9th District Police Capt. Dennis Wilson…was quoted …as saying of the residents: “They’re a hate group. We’re trying to drum up charges against them, but unfortunately we’ll probably have to let them go.”

If they have nothing to hide, they shouldn’t be asking questions.

Shopping center tracking telephone ‘slug trails’

2 Comments

cell phone electronicsA bit of local news from my neck of the woods – the Gunwharf shopping centre (read as: ‘retail outlet experience’, or just ‘mall’) in Portsmouth is keeping a close eye on its customers by tracking their movements via their mobile phone signals. [image by A Magill]

A spokesperson explains that we shouldn’t be concerned: there’s no personal data captured, they’re just looking at what he charmingly refers to as ‘slug trails’:

“We can also see where people aren’t going or are not spending much time and can flag that up to businesses. We are trying to make the experience of shoppers better. If they are having a better experience they obviously spend more money and the shopping centre is happy.“

The shopping centre may be happy, but the local population – now alerted to the matter – aren’t. Whether any of them will transcend their apathy enough to stop shopping there remains to be seen, however. In the meantime, I think I’ll set up a stall outside selling tin-foil phone sleeves …
