Google patents AI system to verify user identity from device interactions

Patent drawing
Patent drawing from the official filing.

Google describes a method that uses machine learning to analyze how a user interacts with a device, such as typing or touching the screen. The system turns these actions into digital fingerprints to confirm which user account is currently being used.

Why it mattersThis approach could make logging into devices more secure by recognizing users based on their behavior rather than just passwords.

In the filing’s own words

An example method is provided. Unverified interaction data descriptive of interactions of a user with the computing device can be obtained. Feature values that embed characteristics of the unverified interaction data can be generated using a machine-learned embedding network of a machine-learned verification pipeline. A user account associated with the unverified interaction data can be determined using a verification model of the machine-learned verification pipeline.

What exactly they claim (claim 1)

1. A computer-implemented method comprising: obtaining interaction data descriptive of interactions of a user with a computing device; generating a multidimensional input having a format that indexes the interaction data over a plurality of time steps; providing the multidimensional input for input to a machine-learned embedding network of a machine-learned verification pipeline; generating, using the machine-learned embedding network configured to process the multidimensional input, feature values that embed characteristics of the interaction data; and determining, based on the feature values, a user account associated with the interaction data.
