Abstract
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.
