Claim 18:
19. A computer program product for user verification, comprising:
one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:
program instructions to receive, 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;
program instructions to extract, by the one or more processors, a plurality of features from the interaction data;
program instructions to generate, by the one or more processors, one or more feature vectors;

program instructions to aggregate, by the one or more processors, the plurality of features of the one or more feature vectors;
program instructions to embed, by the one or more processors, the plurality of features within each feature vector and program instructions to project 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

program instructions to generate, by the one or more processors, a verification model as a global binary classification model using the global training dataset.
