Preventing the Revealing of Online Passwords to Inappropriate Websites with LoginInspector
Modern Web browsers do not provide sufficient protection to prevent users from submitting their online passwords to inappropriate websites. As a result, users may accidentally reveal their passwords for high-security websites to inappropriate low-security websites or even phishing websites. In this paper, the authors address this limitation of modern browsers by proposing LoginInspector, a profiling-based warning mechanism. The key idea of LoginInspector is to continuously monitor a user's login actions and securely store hashed domain-specific successful login information to an in-browser database. Later on, whenever the user attempts to log into a website that does not have the corresponding successful login record, LoginInspector will warn and enable the user to make an informed decision on whether to really send this login information to the website.
