ABSTRACT
Security
breaches from computer viruses, spyware, hacker attacks and equipment
theft are costing businesses millions of dollars a year, according to
different surveys around the world. In
today’s complex and ever changing world, the need for security is
paramount. This is especially true when securing Internet access to
restricted web pages, to ensure that only previously qualified people can
gain entry. So for this reason, more and more web pages rely on login
schemes that prompt the user to enter a registered username and a valid
password. Unfortunately,
the human brain is not particularly good at remembering long strings of
mixed numbers and letters, so most people either try to use the same login
information for all their web access, or use weak passwords that can be
easily recovered with just a little social engineering. The more usernames
and passwords users have to remember, the more likely the business is
going to have problems with unauthorized access – a fact highlighted in
many reports covering security issues. The
following application is designed to avoid the latter situation. It is
able to store many usernames and passwords inside a Java Card™ smart
card, which is considered one of the most secure methods to store
confidential information. Whenever
a dialog box appears in an application or web browser requesting a
username and password, these security features can be found on the
externally attached device, which will then automatically complete the
username and password fields for the user, as if he or she were typing
them in.
