Disclosed are systems and methods for increasing the difficulty of data
sniffing. In one embodiment, a system and a method pertain to presenting
information to a user via an output device, the information corresponding
to characters available for identification as part of sensitive
information to be entered by the user, receiving from the user via an
input device identification of information other than the explicit
sensitive information, the received information being indicative of the
sensitive information, such that the sensitive information cannot be
captured directly from the user identification through data sniffing, and
interpreting the identified information to determine the sensitive
information.
