FiFTy: Large-scale File Fragment Type Identification using Neural Networks
Govind Mittal, Pawel Korus, Nasir Memon
We present FiFTy, a modern file type identification tool for memory forensics and data carving. In contrast to previous approaches based on hand-crafted features, we design a compa…
Tap-based User Authentication for Smartwatches
Toan Nguyen, Nasir Memon
This paper presents TapMeIn, an eyes-free, two-factor authentication method for smartwatches. It allows users to tap a memorable melody (tap-password) of their choice anywhere on t…
An HMM-based behavior modeling approach for continuous mobile authentication
Aditi Roy, Tzipora Halevi, Nasir Memon
This paper studies continuous authentication for touch interface based mobile devices. A Hidden Markov Model (HMM) based behavioral template training approach is presented, which d…
An HMM-based Multi-sensor Approach for Continuous Mobile Authentication
Aditi Roy, Tzipora Halevi, Nasir Memon
With the increased popularity of smart phones, there is a greater need to have a robust authentication mechanism that handles various security threats and privacy leakages effectiv…
IllusionPIN: Shoulder-Surfing Resistant Authentication Using Hybrid Images
Athanasios Papadopoulos, Toan Nguyen, Emre Durmus +1
We address the problem of shoulder-surfing attacks on authentication schemes by proposing IllusionPIN (IPIN), a PIN-based authentication method that operates on touchscreen devices…
