A user creates a pattern in a two-dimensional grid by entering a password and enters a user name. This user name, password and pattern are stored locally on a computing device or are transmitted to a remote computer server for later authentication. Upon authentication, a choice of input grids is displayed. The user chooses a grid, enters the password into the grid in the form of the pattern, and also enters the user name. The computer retrieves the previously stored pattern and password with the user name. A match with the stored password indicates authentication. Each cell of the input grid may contain more than one symbol of the password. The input grid may also be filled with random characters to improve security. A grid may be a rectangular matrix, a circular region, an asymmetrical region, or other. |

1. A method of establishing a user identity, said method comprising:
creating, by a computer user, a two-dimensional pattern on a display of a computing device, said pattern including a plurality of cells; receiving, on said computing device, a series of alphanumeric characters forming a password from said computer user entered into said cells of said two-dimensional pattern manually by said computer user, wherein at least one of said cells includes a plurality of said characters of said password, and wherein said characters forming said password do not appear in said cells before entry by said computer user and are found on a keyboard or input screen; determining a set of coordinates that define said pattern; receiving, on said computing device, a unique identifier from said computer user; and storing said set of coordinates, said unique identifier and said password in association with one another in persistent storage, whereby said identity of said computer user may be later authenticated. |
