Abstract
We propose a new PIN-entry method which prevents shoulder surfing attacks effectively. The proposed method uses a random mapping between the PIN digits and alphabets given as challenges to the users. The user’s task is to recognize this mapping and to enter the mapped alphabet sequence instead of directly entering the PIN digits. The intuitive nature and easy interface of the proposed scheme enables the users to learn it easily, and the experimental results in the pilot test show that the new method guarantees fast and reliable authentication. To be precise, the average authentication time was 5.8 to 6.8 seconds, and the average error rate was 3.3 to 6.7%.
