Password input using mouse clicking

Digits are randomly distributed into any number of a first group of sets. A type and frequency of a user input action, such as clicking a computer mouse, is associated with each set. Next, all the digits from each set are randomly distributed into a second group of sets. Each of the second group of sets may contain at most a single digit from one of the first group of sets, but may contain any number of digits total. A user input action, is also associated with each set in the second group. To input a particular digit in the password, the user selects one set of the first group of sets that contains the correct digit and selects one set of the second group of sets that also contains the same digit. Selection may occur by mouse clicking, key pressing or touching a screen. Once all digits of the password have been selected in this manner, the software determines the correct digits of the password by comparing the user selections for each digit in the password. The software outputs a result or stores the input password.
