- With the increasing situation of passwords datasets disclosure, the security of user's account faces rising risks under various kinds of password attack. To protect the security of user authentication system, password strength meter (PSM), which is used to measure user's password strength is widely accepted by Internet service institution. However, traditional PSMs in use today are rarely consider about user's cross-site vulnerable behaviors. In this paper, we first conduct a large scale of password reuse behaviors from 200 million Chinese websites' passwords. Then we propose our new weak-deduction PSM (WDPSM) that inherits the advantage of traditional probabilistic context free methods. Also, our WDPSM is good at model users' cross-site behaviors. Specifically, we perform a series of experiments to show that our weak-deduction PSM outperforms traditional PSMs in gauging weak passwords.
