`As the joke goes, on the Internet nobody knows youíre a dog. But although anonymity has been part of Internet culture since the first browser, itís also a major obstacle to making the Web a safe place to conduct business: Internet fraud and identity theft cost consumers and merchants several billion dollars last year. And many of the other more troubling aspects of the Internet, from spam emails to sexual predators, also have their roots in the ease of masking oneís identity in the online world.
Change, however, is on the way. Already over 20 million PCs worldwide are equipped with a tiny security chip called the Trusted Platform Module, although it is as yet rarely activated. But once merchants and other online services begin to use it, the TPM will do something never before seen on the Internet: provide virtually fool-proof verification that you are who you say you are.’
