Abstract
An interactive method for authentication is based on a shared secret which is in the form of an enumerated pattern of fields on a frame of reference. An instance of the frame of reference comprises an array of characters in which the characters are arranged in a random or other irregular pattern on a grid of content fields. An authentication challenge includes characters from the character set, and is delivered in- or out-of-band. The authentication response includes the enumerated position numbers on the enumerated pattern of the field locations on the grid at which the challenge characters are found.
