ABSTRACT:
A password, unknown to a user to be authenticated by the password, is created by comparing an image provided by the user to a master image. Random differences between the images are found and used to create the password. The password is then validated to determine whether the user is authorized and/or to determine whether a communication provided by the user is to be processed.
