Your PIN Sounds Good! On The Feasibility of PIN Inference Through Audio Leakage
Matteo Cardaioli, Mauro Conti, Kiran Balagani +1
Personal Identification Numbers (PIN) are widely used as authentication method for systems such as Automated Teller Machines (ATMs) and Point of Sale (PoS). Input devices (PIN pads…
PILOT: Password and PIN Information Leakage from Obfuscated Typing Videos
Kiran Balagani, Matteo Cardaioli, Mauro Conti +10
This paper studies leakage of user passwords and PINs based on observations of typing feedback on screens or from projectors in the form of masked characters that indicate keystrok…
Active Authentication of Keyboard Users: Performance Evaluation on 736 Subjects
Md Enamul Karim, Kiran S. Balagani, Aaron Elliott +3
Keystroke timing based active authentication systems are conceptually attractive because: (i) they use the keyboard as the sensor and are not hardware-cost prohibitive, and (ii) th…
HMOG: New Behavioral Biometric Features for Continuous Authentication of Smartphone Users
Zdenka Sitova, Jaroslav Sedenka, Qing Yang +4
We introduce Hand Movement, Orientation, and Grasp (HMOG), a set of behavioral features to continuously authenticate smartphone users. HMOG features unobtrusively capture subtle mi…
Privacy-Preserving Population-Enhanced Biometric Key Generation from Free-Text Keystroke Dynamics
Jaroslav Sedenka, Kiran Balagani, Vir Phoha +1
Biometric key generation techniques are used to reliably generate cryptographic material from biometric signals. Existing constructions require users to perform a particular activi…
