The amount of secure data being stored on mobile devices has grown immensely
in recent years. However, the security measures protecting this data have
stayed static, with few improvements being done to the vulnerabilities of
current authentication methods such as physiological biometrics or passwords.
Instead of these methods, behavioral biometrics has recently been researched as
a solution to these vulnerable authentication methods. In this study, we aim to
contribute to the research being done on behavioral biometrics by creating and
evaluating a user authentication scheme using behavioral biometrics. The
behavioral biometrics used in this study include touch dynamics and phone
movement, and we evaluate the performance of different single-modal and
multi-modal combinations of the two biometrics. Using two publicly available
datasets - BioIdent and Hand Movement Orientation and Grasp (H-MOG), this study
uses seven common machine learning algorithms to evaluate performance. The
algorithms used in the evaluation include Random Forest, Support Vector
Machine, K-Nearest Neighbor, Naive Bayes, Logistic Regression, Multilayer
Perceptron, and Long Short-Term Memory Recurrent Neural Networks, with accuracy
rates reaching as high as 86%.
