Abstract

A system and methods authenticate sensitive information such as passwords. Password characters are transformed into distorted characters and distorted character groups are generated such that each distorted password character is part of a group. An image is created containing the groups and the password or other sensitive information is authenticated when groups are identified within the image that contain the password characters in an expected sequence.
