19. A personal computing device, comprising: means for receiving user input comprising a plurality of keys corresponding to text-based characters; means for displaying on a display of a device at least one pallet illustrating associations between a series of unique non-descriptive graphical figures 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 unique non-descriptive graphical figure is associated with a corresponding text-based character, wherein the series of unique non-descriptive graphical figures comprises a series of unique background colors and a series of unique pen colors; means for receiving input of a text-based character corresponding to a unique non-descriptive graphical figure and displaying the non-descriptive graphical figure in a predetermined display location 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 and displaying the next non-descriptive graphical figure in a next predetermined display location in accordance with the defined sequence scheme until receipt of the sequence is complete; and means for processing the input text-based characters as a user password.
