| Abstract | Despite the recent introduction of biometric identification technology, Personal Identification Numbers (PIN) are the standard for granting access to restricted areas and for authorizing operations on most systems, including mobile phones, payment devices, smart locks. Unfortunately, PINs have several inherent vulnerabilities and expose users to different types of social engineering attacks. Specifically, the risk of shoulder surfing in PIN-based authentication is especially high for individuals who are blind. In this paper, we introduce a new method for improving the trade-off between security and accessibility in PIN-based authentication systems. Our proposed solution aims at minimizing the threats posed by malicious agents while maintaining a low level of complexity for the user. We present the method and discuss the results of an evaluation study that demonstrates the advantages of our solution compared to state-of-the-art systems. |
