Password-based authentication is one of the most widely used methods to authenticate a user before granting accesses to secure websites: it is easy for a user to enter her password anywhere by a keyboard or a touch screen without any other assistant devices. However, password creation has significant regional features. The password leakage events offer us a chance to know how different patterns different regional passwords have. In this talk, I will introduce our recent research of the empirical study on Chinese Web Passwords, because it is important to understand the password patterns in the Chinese Netizens who are the biggest user group (0ver 600 million) in the world. We found several interesting patterns in Chinese Web passwords, and quantitatively analyze them. Finally, we introduce how to leverage these patterns to improve the efficiency of password guessing.
