Is Spam solved by 2006?

[Rolo]

DAVOS, Switzerland - A spam-free world by 2006? That's what Microsoft Corp. chairman Bill Gates is promising.

"Two years from now, spam will be solved," he told a select group of World Economic Forum participants at this Alpine ski resort. "And a lot of progress this year," he added at the event late Friday, hosted by U.S. talk show host Charlie Rose.

Gates said Microsoft, where he has the title of chief software designer, is working on a solution based on the concept of "proof," or identifying the sender of the e-mail.

One method involves a human challenge, or requiring the sender of an electronic pitch to solve a puzzle that only a flesh-and-blood person can handle. Another is a so-called "computational puzzle" that a computer sending only a few messages could easily handle, but that would be prohibitively expensive for a mass-mailer.

But the most promising, Gates said, was a method that would hit the sender of an e-mail in the pocketbook.

People would set a level of monetary risk — low or high, depending on their choice — for receiving e-mail from strangers. If the e-mail turns out to be from a long-lost relative, for example, the recipient would charge nothing. But if it is unwanted spam, the sender would have to fork over the cash.

"In the long run, the monetary (method) will be dominant," Gates predicted.

He conceded, however, that his prognostications have not always been on the mark. Notable misjudgments include the rising popularity of open-source software, epitomized by Linux, and the success of the Google search engine.
