Abstract

Personal identification numbers (PINs) and hardware tokens are often used together for authentication purposes, e.g., in financial transactions with ATM machines. However, many people cannot remember their PINs. This has caused insecure practice, extra management cost, or both. In this paper, we evaluate FacePIN, a solution proposed to improve the security and memorability of the PIN scheme.
