Title (EN) CALL AUTHENTICATION USING CALL FORWARDING
(FR) AUTHENTIFICATION D'APPEL À L'AIDE D'UN TRANSFERT D'APPEL
Abstract:
(EN) The invention may verify calls to a telephone device by activating call forwarding to redirect calls for the telephone device to a prescribed destination; receiving a message from a server verifying the call; deactivating call forwarding to receive the call; and reactivating call forwarding when the call is concluded. In another embodiment, the invention may, in response to a telephone device initiating a call to a second telephone device installed with a particular application or software, transmit a message to a server causing it to instruct the second telephone device to deactivate call forwarding. In yet another embodiment, the invention may cause a server to receive a message from a prescribed location indicating that a call was received via call forwarding, and in response to the message, transmit an instruction to the intended recipient to deactivate the call forwarding if the call is verified as legitimate.
(FR) L'invention permet de vérifier les appels vers un dispositif téléphonique en activant le transfert d'appel pour rediriger les appels pour le dispositif téléphonique jusqu'à une destination prescrite; en recevant un message provenant d'un serveur qui vérifie l'appel; en désactivant le transfert d'appel pour recevoir l'appel; et en réactivant le transfert d'appel lorsque l'appel est terminé. Dans un autre mode de réalisation, l'invention permet, en réponse à un dispositif téléphonique, d'initier un appel vers un second dispositif téléphonique où est installé(e) une application ou un logiciel particuliers, de transmettre un message à un serveur, ce qui lui permet de donner l'instruction au second dispositif téléphonique de désactiver le transfert d'appel. Dans un autre mode de réalisation encore, l'invention peut amener un serveur à recevoir un message d'un emplacement prescrit indiquant qu'un appel a été reçu par l'intermédiaire d'un renvoi d'appel, et en réponse au message, transmettre une instruction au destinataire prévu pour désactiver le transfert d'appel si l'appel est vérifié comme étant légitime.
