Just as with your laptop. Create a fake login.

So when someone beats you with a phone book or a tirewrench, you can say "the login is jdoe, password 123!" and they'll login and see your not so important files. When actually your login is janedoe password abc.

Same applies with encrypted partitions in your setup. Have a partition A at index N and a partition B at index M. A,N is the fake one, complete with files recently modified (.bashrc and cron will help with that). And B,M is your normal secure parition.

The system is no better than having a normal credit card CVV.

The LCD-like half-images are the secret. Take a photo of that and you're totally compromised.

The battery systems (like RSA SecurID) are better because they protect the secret inside the deviceand only give a derived value every 60 seconds.

Nice try however.

This news is actually over 50 years old.

Pop reference you can check out: "It's a Wonder Life" - the flash-back scene where the lead charactor's friend tells me "there's a great investment oppertunity with Soy farmers, they're going to make plastics!" - or something like that.

Mr Tupper (Tupperware fame) made it big by using fuel refinement waste to make plastics - there by removing the bottleneck of growing Soy.

The key is to make the bots/spammers use more resources then they have.

Something like this can be used to slow down email address scanning bots.

Like sending email with hashcash, if you make the scammers work to get the right answer by requiring to compute a computationally complex formula (crypto function random walk distinguished points), they will not be able to keep up.

A website can pre-compute a table of (and continuously add to that table) challange-responses that a visitor must perform. A human will see a 5-15 second delay to registration, to a bot this can be intolorable.

Here's a URL that uses PHP/GoogleGadgets/JavaScript/CronJobs to present historical graphs of published electrical generation data for the province of Ontario. jlcooke.ca/ieso Electrical consumption drops during Earth Hour, but generation does not. Think about it — if you ran a generating station that burns hamsters to boil water to spin a turbine to produce electricity — would you turn it off for 1 hour? How long would it take to get it back up to full power? The problem with Earth Hour is in the name — it's only an hour."

MD5CRK used a JavaApplet that used this Chinese Lottery concept. The applet performed 95% as fast as a pure C implementation of MD5. JavaScript is another matter however. And an assebly code that inlieved MMX/SSE with ALU was much faster.

Background threads in browsers will help of course.

Security

Jean-Luc Cooke writes "The large (and largely mismanaged) ecommerce.com (aka. opentransfer.com, etc) has some web servers hacked. In a cleaver way of not getting detected, it only affects users that visit those sites from a search engine. If the Referer HTTP header contains google or some other popular search engine names, then you get redirected to a malware install site. Try it yourself: search for "Delicious Alternatives" on google, click the first link. Some telnet experiments will confirm the trigger is in the HTTP header."

Submitted by

NewYorkCountryLawyer writes "Ohio University, in Athens, Ohio, has found the key to getting the RIAA to stop inundating it and its students with "settlement" letters. According to the university's student online publication, the university paid $60,000, plus $16,000 per year "maintenance", to Audible Magic, the business partner of the RIAA's all-purpose expert witness Dr. Doug Jacobson, for its "CopySense" filtering software. Once it made the payments, the letters stopped. This of course raises a lot of questions as to the 'disinterestedness' of Dr. Jacobson, whose deposition in the UMG v. Lindor case was the subject of interesting Slashdot commentary."

Holocaust Dropped From Some UK Schools 1286

Posted by kdawson
from the careful-you-might-offend-somebody dept.
dteichman2 writes "It appears that some UK schools are ignoring the Holocaust. A government-backed study, funded by the Department for Education and Skills, found that some teachers are reluctant to teach history lessons on the Holocaust for fear of offending Muslim students whose beliefs include Holocaust denial. Additionally, similar problems are being encountered with lessons on the Crusades because these lessons contradict teachings from local mosques."
Businesses

+ - IT Pros are Slackers!

Submitted by Anonymous
Anonymous (666) writes "In a recent editorial column, CIO Insight executive editor Eric Chabrow writes that despite the perception that IT pros are overworked, "all other professions, save one, work longer hours on average each week than IT workers." The typical full-time computer professional last year averaged 42 hours, 24 minutes per week on the job — at the office, on the road and at home, he says, citing figures from the U.S. Bureau of Labor Statistics.
"A few readers doubted the data's accuracy because they don't trust anything the government says. Others felt employers intentionally underreported the hours their IT pros worked. But that wasn't the case. The reported hours came from the employees themselves or a family member interviewed by trained government survey takers."
Chabrow believes the numbers "reflect reality, though they could be off a few hours a week."
And the one profession that works fewer hours than IT? "The category that includes educators, trainers and librarians averages the fewest hours on the job, at 41 hours, 18 minutes.""

neraath writes "Ben Maurer posted on his blog a new concept to 2 very old problems: Captchas and digitally scanning books. Spammers have been continually getting better at their methods of mayhem to crack Captchas, and scanners work hard to figure out the words scanned in from books. Combined the two and you have ReCaptcha, a step towards better captchas and helping computers figure out "what is that word"."
