The system and method provides for the authentication of a user based on graphical input provided by the user. The user enters graphical input, such as a squiggle, into a graphical interface. A verifier compares the input pattern to a secret input pattern to determine if the two patterns are approximately similar in order to authenticate the user. Typically, the verifier uses an approximation parameter to determine if the input and secret patterns are similar. Once the verifier authenticates the user, the user is allowed access to a resource, such as a computer system, portable computer, software application running on a computer system or other hardware device. |
