1. Generating user behavior models for verification across devices, comprising:
receiving device usage data generated by monitoring user-device interactions of a first set of users interacting with a first device and a second set of users interacting with a second device;
for each one of a set of features:
generating a first set of feature samples from the user-device interactions of the first set of users, and generating a second set of feature samples from the user-device interactions of the second set of users;
generating a score for the feature based on an analysis of the first set of feature samples and the second set of feature samples, wherein the feature score indicates a degree to which the first set of feature samples and the second set of feature samples differentiate between the devices;
identifying the feature as transferrable upon the score being below a specified threshold; and
for a specific user, generating a new behavior model for use with a new device by modifying existing user behavior data applicable for an existing device according to the transferrable features.
