Abstract: An electronic device is provided. The electronic device includes an input/output interface and at least one processor configured to irreversibly generate a first token to use or access an object based on first biometric information input through the input/output interface and information proving ownership of the object, and output the first token through the input/output interface.

Abstract: A user authentication method, by which a device authenticates a user, is provided. The user authentication method includes performing basic authentication based on a received user input, obtaining behavioral characteristics with which the user uses the device, and when the user has passed the basic authentication, performing additional authentication for the user by applying the obtained behavioral characteristics to a first learning model, wherein the first learning model is a model trained to perform the additional authentication for the user, based on at least one of a plurality of behavioral characteristics of an authenticated user, the behavioral characteristics being accumulated in the device.
