Abstract
A system and method for inputting a password. The system and method operates to associate unique non-descriptive graphical features with unique text-based characters. The system and method operates to receive in sequence, a plurality of text-based characters. The system and method operates to display in sequence, in accordance with a sequence scheme, the non-descriptive graphical features associated with the plurality of text-based characters. The system and method also operates to process the plurality of text-based characters as the password. In addition, the system and method operates wherein the password, including text-based characters, may be deciphered from both the display of the non-descriptive graphical features associated with the plurality of text-based characters and the sequence scheme.

A method of user authentication, comprising:
- displaying on a display of a device at least one pallet illustrating associations between a series of unique background colors and corresponding unique text-based characters, wherein each text-based character corresponds to one of a plurality of keys comprising an input mechanism of the device and wherein each background color is associated with a corresponding text-based character;
- receiving input of a text-based character corresponding to a particular background color of the graphical password;
- displaying on the display of the device at least one pallet illustrating associations between a series of unique pen colors and corresponding unique text-based characters, wherein each pen color is associated with a corresponding text-based character;
- receiving input of a text-based character corresponding to a particular pen color of the graphical password;
- displaying on the display of the device at least one pallet illustrating associations between a series of unique non-descriptive graphical figures and corresponding unique text-based characters, wherein each graphical figure is associated with a corresponding text-based character;
- receiving input of a text-based character corresponding to a non-descriptive graphical figure of the graphical password and displaying the non-descriptive graphical figure in a predetermined grid location of a 3×3 grid in accordance with a defined sequence scheme comprising rules for the order of entry of a sequence, and repeating receiving input of a text-based character corresponding to a next non-descriptive graphical figure of the graphical password and displaying the next non-descriptive graphical figure in a next predetermined grid location of the 3×3 grid in accordance with the defined sequence scheme until receipt of the sequence is complete;
- and
- processing the input text-based characters as a user password.
