Abstract
A user generates a pattern in a matrix (or two-dimensional grid) and enters a user name and an associated password. This username, password and pattern are stored locally on a computing device or are transmitted to a remote computer server for later authentication. Upon authentication, an input matrix is displayed. The user enters the password into the matrix in the form of the pattern, and also enters the username. The computer retrieves the previously stored pattern and password with the username. The previously stored pattern is used to read the input password from the input matrix. A match with the stored password indicates authentication. Alternatively, the input matrix only includes the pattern and password is entered separately. The input matrix may also be filled with random characters to improve security. The stored pattern is compared to the input pattern using image analysis or by comparing a set of coordinates.
