StrokePIN: Enhancing PIN Authentication With Keystroke Dynamics for Mobile Devices
- Published
- Record updated
Summary
StrokePIN is a PIN authentication system for mobile devices that combines keystroke dynamics with a Siamese Network, a few-shot learning technique that deploys without retraining. The authors collected two new multi-modality datasets covering 20 PINs from 116 users, which they made publicly available. On unseen users the system reports an FAR of 2.2% and an FRR of 1.9%, and entropy analysis puts keystroke dynamics at 4.03-5.83 bits of security against 3 to 10 online guessing attacks.
