METHOD AND DEVICE FOR CHARACTERISING A USER, AND DEVICE FOR PROVIDING SERVICES USING SAME

A method and a device for characterizing a user, in particular a user of a device and/or a service in the field of computer security. The characterization method includes: a comparison of first data associated with a first sound object spatialized at a first location by a user interface of a communication terminal and second data received following the reproduction of the first spatialized sound object, the second data being based on a second spatialized sound object perceived at a second location. The comparison triggers, in the event of a positive result, a characterization of the source of interaction as being a suitable user. Thus, errors in characterizing a user as a suitable user, in particular a human user, are reduced because existing sound and speech recognition systems are not able to select a sound in a spatialized sound environment, i.e. a 3D audio scene.
