Abstract
In these days, smartphones are being widely used, people use them to store sensitive and private information. The password authentication is the most used authentication method, however, the password can be disclosure through shoulder surfing attack, since the users write their password in public places and they tend to make the password easy to remember which increase the vulnerability to attacks. Many authentications schemes were proposed to prevent shoulder surfing attack, but they still vulnerable to shoulder surfing attack or have accuracy problems or lack in usability. In this paper, we proposed a gaze-text based PIN entry method, which we called PathGazePIN. It will utilize the user's eye movement to enter the password. The main idea is allowing the user to authenticate by following numbers that move along fixed paths on the screen by using two authentication interfaces: random interface and sorted interface. The results represented that the proposed system will increase the security against shoulder surfing attack as well as usability and accuracy.
