Continuous Authentication Using One-class Classifiers and their Fusion
Rajesh Kumar, Partha Pratim Kundu, Vir V. Phoha
While developing continuous authentication systems (CAS), we generally assume that samples from both genuine and impostor classes are readily available. However, the assumption may…
Continuous User Authentication via Unlabeled Phone Movement Patterns
Rajesh Kumar, Partha Pratim Kundu, Diksha Shukla +1
In this paper, we propose a novel continuous authentication system for smartphone users. The proposed system entirely relies on unlabeled phone movement patterns collected through…
Curie: A method for protecting SVM Classifier from Poisoning Attack
Ricky Laishram, Vir Virander Phoha
Machine learning is used in a number of security related applications such as biometric user authentication, speaker identification etc. A type of causative integrity attack agains…
Authenticating users through their arm movement patterns
Rajesh Kumar, Vir V Phoha, Rahul Raina
In this paper, we propose four continuous authentication designs by using the characteristics of arm movements while individuals walk. The first design uses acceleration of arms ca…
