Spy-busting black box promises better PC security
Screen radiation can give away details of what's on display
Did you know that the very weak electromagnetic radiation given off by a computer screen can be captured up to 100m away and reassembled into an exact copy of what's on the screen?
Neither did we but, apparently, Japan's NTT has long known about the security risk and has even developed a handy little device to protect sensitive computers against such data theft.
Black box of tricks
The as-yet-unnamed black box will go on sale this autumn to government bodies and banks, where data security is at a premium. In those institutions it will offer a cheaper alternative to existing methods.
Those include either shielding entire data centres or using special PCs that don't emit any electromagnetic (EM) radiation. Both options are extremely expensive.
Instead, NTT's device effectively blurs out a screen's EM signature by connecting to a PC by USB and superimposing its own radiation over that given off by the computer. The result is a completely unreadable EM wave.
NTT plans to sell its box later this yearfor the equivalent of a few hundred pounds.
Anti-radiation maternity clothes in ChinaJul 18, 2008 10:20
Here's one for the guys at Mythbusters. Many Chinese women guard against supposed computer radiation using these special anti-radiation maternity dresses. I've always found it strange that these dresses are so commonplace in China, but yet I haven't seen them in any other countries. A quick search on eBay for "anti-radiation maternity dress" gave 13 results, all of them China-based sellers.
Companies such as Leyun, Shaoxing, and Tianxiang all sell these protective aprons. Alibaba is full of 'em, too. Very few Chinese women whom I've spoken to question the supposed negative effects of radiation coming from their monitors. It appears to be common knowledge that these special aprons are needed if you're pregnant. But yet the WHO says in this 2007 fact sheet "that there are no substantive health issues related to ELF electric fields at levels generally encountered by members of the public".
Added to story - ( Another false statement by the World Health Authority, MW)
Nevertheless, companies such as Leyun are including this kind of rhetoric in their marketing:
Knowledge of electromagnetic radiation
Computer has become an indispensable part of our daily life. It's used at work, games and for entertainment purposes. However, the radiation of computer and the electromagnetic wave it generates can cause harm to human body on such aspects as:
- Dizziness, fatigue, insomnia and neurasthenia syndromes, etc.
- Cardiovascular disease, high blood pressure, palpitation and autonomic dysfunction;
- Abortion, fetus abnormal and chromosome aberration;
- Female menstrual cycle disorder, male sexual function decline, hair loss and white hair;
- Leukemia (especially more dangerous for children), cancer, tumors, causes harm to human body's immune system and thus silently hurts our health.Production Introduction
