Abstract—In this study, we discuss password-based authentication methods that use the vibration function on smartphones. Password-based methods are relatively simple and are occasionally used as a backup when other methods fail. The main research goal in this area is to prevent shoulder surfing or video-recording attacks, which can be achieved by using vibrations to transmit secret information to users. Authentication succeeds when the user correctly incorporates the received secret information into the process. However, conventional vibration-based methods are slow, and reducing the time required would improve usability. We discuss ways of achieving this, leading us to propose a new, relatively fast authentication method that is nonetheless resistant to multiple-video-recording attacks.
Index Terms—Password authentication method, multiple-video-recording attack, vibration.
