BEHAVIORAL BIOMETRICS VERIFICATION ADAPTATION FOR CROSS DEVICES

Techniques for verifying the identity of users transferring between devices are disclosed. An example method includes receiving device usage data 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. The method also includes extracting features from the data and aggregating feature samples from the user-device interactions for first set of users and the second set of users. The method also includes generating a score for each feature based on an analysis the feature samples. 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. The method also includes identifying features as transferrable if the score is below a specified threshold, and generating a new behavior model by modifying existing user behavior data according to the transferrable features.
