Abstract
(EN) In one embodiment, a method includes detecting a triggering event to initiate a communication session with a second computing device associated with a second user, where the first computing device includes one or more wireless transceivers and one or more sensors, determining an initial trust score for the second computing device, sensing physical interactions between users using the one or more sensors, adjusting the trust score for the second computing device based at least on the sensed physical interactions, and sending a message to the second computing device if the adjusted trust score for the second computing device satisfies a first threshold.
(FR) Un mode de réalisation de l’invention concerne un procédé consistant à : détecter un événement déclencheur pour initier une session de communication avec un second dispositif informatique associé à un second utilisateur, le premier dispositif informatique comprenant un ou plusieurs émetteurs-récepteurs sans fil et un ou plusieurs capteurs ; déterminer un score de confiance initial pour le second dispositif informatique ; détecter des interactions physiques entre des utilisateurs à l'aide du ou des capteurs ; ajuster le score de confiance pour le second dispositif informatique sur la base au moins des interactions physiques détectées ; et envoyer un message au second dispositif informatique si le score de confiance ajusté pour le second dispositif informatique satisfait un premier seuil.
