These inertial sensors are commonly integrated into smartphones and are widely used by the average person, which makes …
Deep learning predicts user identity, activity, and location from Wi-Fi signals.
User authentication and intrusion detection differ from standard classification problems in that while we have data generated from legitimate users, impostor or intrusion data is scarce or non-existent. We review existing techniques for dealing with this problem and propose a novel alternative based on a principled sta…
Subspace clustering (SC) refers to the problem of clustering high-dimensional data into a union of low-dimensional subspaces. Based on spectral clustering, state-of-the-art approaches solve SC problem within a two-stage framework. In the first stage, data representation techniques are applied to draw an affinity matrix…
Active authentication is the problem of continuously verifying the identity of a person based on behavioral aspects of their interaction with a computing device.
