BioTouchPass: Handwritten Passwords for Touchscreen Biometrics. (arXiv:2205.01353v1 [cs.CR])

This work enhances traditional authentication systems based on Personal
Identification Numbers (PIN) and One-Time Passwords (OTP) through the
incorporation of biometric information as a second level of user
authentication. In our proposed approach, users draw each digit of the password
on the touchscreen of the device instead of typing them as usual. A complete
analysis of our proposed biometric system is carried out regarding the
discriminative power of each handwritten digit and the robustness when
increasing the length of the …
