Abstract: A method of generating a non-linear spatial and chromatic password includes the steps of establishing a spatial password entry pattern (SPEP) within boundary conditions of a matrix of a password entry screen (PES), the SPEP including coordinates of the matrix of the PPS. The method also includes selecting a first color from a color selection keypad (CSK) having many selectable colors. The first color is then mapped to a first coordinate of the SPEP of the matrix. Then, a second color from said CSK is mapped to a second coordinate of said SPEP. The above steps of selection and mapping are then repeated for N coordinates, each corresponding to a selected color of the CSK, until all coordinates falling within the boundary conditions defining said non-linear SPEP are fully mapped. A high security, high anti-decryption, spatial and chromic password results.
