Elastic password authentication scheme using the Passcell-based virtual scroll wheel

Abstract

User authentication such as password setting has become increasingly important for the secure management of the information stored in mobile devices. However, in the password authentication schemes used in mobile devices, enhancing security reduces their usability, and passwords become hard to memorize. In addition, enhancing their usability makes them vulnerable to shoulder-surfing or recording attacks involving stealing a glance at the authentication process through the system interface. In this paper, we propose a password authentication scheme that uses a virtual scroll wheel, called WheelLock, to ensure appropriate usability and prevent brute force, shoulder-surfing, and recording attacks.

Keystroke Dynamic Authentication in Mobile Cloud Computing

“…PIN is adopted as the only security mechanism for mobile devices. It is obvious that, PIN (something the user knows) is not very secure mechanism for authenticating users because of its limitation, as well as it is difficult to confirm that the demand is from the rightful owner [17,44].…”
