Abstract
User verification using a mobile interaction can include receiving interaction data associated with a user of an application operating on a mobile device, the interaction data is generated during an interactive session of the user with the application on the mobile device. A plurality of features are extracted from the interaction data and one or more feature vectors are generated from the plurality of features. The plurality of features are aggregated to the one or more feature vectors and embedded within each feature vector. The embedded plurality of features are then projected to a global feature space by comparing a history of interactive sessions associated with the user and a history of interactive sessions associated with a plurality of different users for generating a global training dataset. Finally, a verification model is generated as a global binary classification model using the global training dataset.
