Abstract
From the late 1990’s, researchers have dedicated to find the alternative authentication methods for Textual Password to solve the many shortcuts in it such as the keyboard logger and dictionary attack threats. Among many of these methods, the most represented one might be graphical password. Based on some of the specific qualities of it, the security level increases. In this thesis, we first review many related authentication method now presented and what shoulder surfing problem is, analyzing them and their difference. In the awareness of nowadays misuse of the word ‘shoulder surfing resistant’, we presented ‘sub shoulder surfing resistant’ concept. In last, we present a user defined pass mechanism authentication method and compare it to the many methods now existed. We also explain what user defined pass mechanism’s advantage is. What we are going to discuss in this thesis does not contain those bio-authentication method containing person-to-person variant information. The most widely discussed and most representative method might be Graphical Password since some of its unique features make logging more difficult for mal-intention attackers.
