Thermal (and Hybrid Thermal/Audio) Side-Channel Attacks on Keyboard Input
Tyler Kaczmarek, Ercan Ozturk, Pier Paolo Tricomi +1
To date, there has been no systematic investigation of thermal profiles of keyboards, and thus no efforts have been made to secure them. This serves as our main motivation for cons…
Proactive Provenance Policies for Automatic Cryptographic Data Centric Security
Shamaria Engram, Tyler Kaczmarek, Alice Lee +1
Data provenance analysis has been used as an assistive measure for ensuring system integrity. However, such techniques are typically reactive approaches to identify the root cause…
Thermanator: Thermal Residue-Based Post Factum Attacks On Keyboard Password Entry
Tyler Kaczmarek, Ercan Ozturk, Gene Tsudik
As a warm-blooded mammalian species, we humans routinely leave thermal residues on various objects with which we come in contact. This includes common input devices, such as keyboa…
Assentication: User Deauthentication and Lunchtime Attack Mitigation with Seated Posture Biometric
Tyler Kaczmarek, Ercan Ozturk, Gene Tsudik
Biometric techniques are often used as an extra security factor in authenticating human users. Numerous biometrics have been proposed and evaluated, each with its own set of benefi…
Lights, Camera, Action! Exploring Effects of Visual Distractions on Completion of Security Tasks
Bruce Berg, Tyler Kaczmarek, Alfred Kobsa +1
Human errors in performing security-critical tasks are typically blamed on the complexity of those tasks. However, such errors can also occur because of (possibly unexpected) senso…
