Classification: CPC G | IPC G

Claim 0:
1. A computer-implemented method for user verification, comprising:
receiving, by one or more processors, interaction data associated with a user of an application operating on a mobile device, the interaction data being generated during an interactive session of the user with the application on the mobile device;
extracting, by the one or more processors, a plurality of features from the interaction data;
generating, by the one or more processors, one or more feature vectors;
aggregating, by the one or more processors, the plurality of features of the one or more feature vectors;
embedding, by the one or more processors, the plurality of features within each feature vector and projecting the embedded plurality of features within each feature vector 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; and
generating, by the one or more processors, a verification model as a global binary classification model using the global training dataset.
