The affords anonymity to its users, a blessing to privacy and freedom of speech. But
that very anonymity is also behind the explosion of cyber-crime that has 1 across the Web.
Can privacy be preserved 2 bringing safety and security to a world that seems
increasingly 3 ?
Last month, Howard Schmidt, the nation’s cyber-czar, offered the federal government
a 4 to make the Web a safer place-a “voluntary trusted identity” system that would be the
high-tech 5 of a physical key, a fingerprint and a photo ID card, all rolled 6 one. The system
might use a smart identity card, or a digital credential 7 to a puter .and would
authenticate users at a range of online services.
The idea is to 8 a federation of private online identity systems. User could 9 which
system to join, and only registered users whose identities have been authenticated could navigate
those systems. The approach contrasts with one that would require an driver’s
license 10 by the government.
Google and Microsoft are panies that already have these“single sign-on” systems
that make it possible for users to 11 just once but use many different services.
12 .the approach would create a “walled garden” n cyberspace, with safe “neighborhoods”
and bright “streetlights” to establish a sense of a munity.
Mr. Schmidt described it as a “voluntary ecosystem” in which “individuals anizations
plete online transactions with 14 ,trusting the identities of each other and the identities
of the infrastructure 15 which the transaction runs”.
Still, the administration’s plan has 16 privacy rights activists. Some applaud the approach;
others are concerned. It seems clear that such a scheme is an initiative push toward what
would 17 be pulsory “drive’s license” mentality.
