Advanced Authentication Scheme Using a Predefined Keystroke Structure

This paper presents an advanced keystroke authentication model improving users' validation strength. The proposed system is based on defining a keystroke structure for each authorized user, to be used in the user login attempts. This structure is composed based on two components; the user's typing time deviation thresholds; and a unique user secret code which is distributed between password's characters based on time distances. The strength of the proposed method depends primarily on the amount of information distributed among typing time, and on reducing the deviation of these times. During the preliminary evaluation, it was confirmed that the proposed system has achieved an improved authentication level, and the system model was highly accepted between participating users.
