Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A computer system for user verification, comprising:
one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method 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.
