America Online now offers something more than passwords to protect user accounts. For an extra charge, AOL offers a gadget that displays a six-digit code that changes from minute to minute.
These matchbook-sized devices, made by RSA Security, resemble those often used on sensitive corporate or institutional networks. A user must enter the six-digit code displayed on the device to login-and the number changes often enough to discourage eavesdroppers and snoops.
These optional security codes will not affect all internet access. They only protect AOL's proprietary online service, not outside websites. Curiously, AOL Instant Messenger will also be unprotected.
The extra service costs $1.95 per month, plus a one-time $9.95 fee. AOL hopes to attract a niche group of subscribers-small-business owners, identity-theft victims, and those who make many online transactions-for the premium service. The move could spur other major internet service providers to follow suit, possibly with their own numeric codes, fingerprint scanners, or smart cards.
Editors at large
A new online medium allows anyone with an internet connection the opportunity to be an editor. Known as a wiki, this new type of reference seeks to combine the expertise of large groups.
Each wiki (the word is derived from wiki wiki which means "quick" in Hawaiian) is like the whiteboard in a virtual conference room, where all participants get markers to add their own contributions. Any user can add, edit, and erase text on the page. "You can feel like your voice is just as loud and your opinion is worth as much as everyone else," said John Bobowicz, founder of several wikis.
The concept dates back to 1995 and is now used for everything from software manuals to cookbooks. The Wikipedia, a huge virtual encyclopedia, has 350,000 English entries and over 25,000 contributors. Dozens of users patrol the collection, trying to stop vandalism.
Wikis have disadvantages, though, including the domination of groupthink. (A user's addition must be acceptable to others or else they will erase it.) Wikis also lack staff researchers, copy editors, fact checkers, and others who help ensure that a published text is accurate. Spammers have also invaded many wikis.
