Abstract
Systems and methods for providing encryption and decryption of data transmitted on a computer implemented network, preferably user authentication identifier data, such as a password, at the point of entry into the user's computer. The systems and methods enable an end user to mentally select a marker from one of the randomly arranged elements on a first portion of a graphical image. A second portion of the graphical image includes an arrangement of possible elements of any individual authentication identifier sequence, and is positioned adjacent to the first portion. The systems and methods prompt a user to enter each element of the identifier by moving the selected marker and the first portion as necessary to substantially align the selected marker with a chosen element of the authentication identifier appearing on the outer portion. According to one embodiment, the image portions are concentric wheels. According to another embodiment, the image portions are arranged in adjacent rows.
