Abstract
The present invention relates to a password input algorithm, more particularly to a password input system and method using alphanumeric matrices. An aspect of the invention can provide a password input system and method using alphanumeric matrices that can defend against keylogging attacks and shoulder surfing attacks by including a movable second alphanumeric matrix and a fixed first alphanumeric matrix and enabling a user to input a password by moving the password letters of the second alphanumeric matrix to the user-defined value of the first alphanumeric matrix. Another aspect of the invention can provide a password input system and method using alphanumeric matrices that can defend against shoulder surfing attacks by enabling a user to input a password by dividing the password by every two digits and moving the cross-points for the two digits, respectively, to the user-defined value of the first alphanumeric matrix.
