Two-stage security next step in helping protect transactions

To access her bank account online, Marie Jubran
opens a Web browser and types in her Swedish national ID number along with a
four-digit password.
For additional security, she then pulls out a card that has 50
scratch-off codes. Jubran uses the codes, one by one, each time she logs on
or performs a transaction. Her bank, Nordea PLC, automatically sends
her a new card when she's about to run out.
As more Web sites are demanding passwords, scammers are getting more
clever about stealing them. Hence the need for such "passwords-plus"
systems.
Scandinavian countries are among the leaders as many online businesses
abandon static passwords in favour of so-called two-factor authentication.
"A password is a construct of the past that has run out of steam," said
Joseph Atick, chief executive of Identix, Inc., a Minnesota designer of
fingerprint-based authentication. "The human mindset is not used to
dealing with so many different passwords and so many different PINs."
When a static password alone is required, security experts recommend that
users combine letters and numbers and avoid easy-to-guess passwords like
"1234" or a nickname.
Stevan Hoffacker follows those rules but commits a different faux pas: He
uses the same password everywhere, including access to multiple e-mail
accounts, Amazon.com, The New York Times Web Site. and E-Z pass electronic
toll statements.
In such cases, should hackers or scammers compromise one account, they
potentially have one's entire online life.
"This is one of those things that if I stop and think about it, it is not
good, but I do my best not to stop and think about it," said Hoffacker, an
information technology manager in New York.
But it is difficult to remember dozens of strong passwords - so many
sites now require them. Alternatives include writing them down on a sticky
note attached to a monitor or in an electronic spreadsheet - practices
security experts also deem unsafe.
Software such as Symantec Corp.'s Norton Password Manager and Apple
Computer Inc.'s Keychain help store passwords in secure, encrypted form.
But if you compromise the master password, you're out of luck. Your
entire collection is gone.
Many sites, meanwhile, will e-mail passwords insecurely - without
encryption - if you forget. A site called BugMeNot.com even encourages
users to share passwords for non-financial sites like newspapers.
The tolls of password harvesting are many:
Keystroke recorders secretly installed
at public Internet terminals can capture passwords, as can "phishing"
e-mails designed to trick users into submitting sensitive data to fraudulent
sites that look authentic. There are computer viruses programmed to harvest
passwords as well as software that guesses passwords by running through
words in dictionaries.
Though analysts have no hard figures on password-specific fraud, they
blame insecure passwords for unauthorized financial transfers, privacy
breaches and even the hacking of corporate networks.
With two-factor authentication, having a password alone is useless.
"We will never play the fear factor here, but still it stays a fact that
with our products, phishing is no longer an issue," said Jochem Binst of
Vasco Data Security International Inc.
The Belgian company issues devices the size of pocket calculators or key
chains. You type your regular password into the device for a second
code that is based on the time and the unit's unique characteristics.
That's the code you type into the Web site.
Someone who steals your device won't have your password; someone who
steals your password won't have your device.
MasterCard International Inc. has been testing similar systems in
Britain, Germany and Brazil. Swipe a card with a smart chip into a
special reader, enter your PIN and obtain a password good only once at
Office Max, British Airways and a dozen other merchants.
In Singapore, bank customers wishing to designate new accounts for fund
transfers must likewise obtain a second password -- through a phone call,
e-mail or mobile text messaging.
Biometric systems are similar, except a fingerprint or iris scan replaces
one or both passwords.
