Abstract
An interactive method for authentication is based on two shared secrets, both shared secrets in the form of an ordered path on the frame of reference. An instance of the frame of reference comprises a set of characters which is arranged in a random or other irregular pattern. The first step of authentication that a user performs requires the user to remember one or all of the characters in the displayed instance of the frame of reference found in the locations in the random subset of the first ordered path by indicating characters either in these locations, or any other locations having the same characters. The second step of authentication requires that a user enter the position of the second ordered path, which only they know during an authentication session, where the challenge identifying the position of the ordered path is the single or multiple values that matches the value of the digital content of the frame of reference.
