<p>For filtering messages that are received by a controlling node (CN) and are to be sent toward a destination device within a telecommunication network (TN), a controlling device receives a set of data from a terminal (UT) of a user, calculates a set of features (SF) of the set of data, and stores the calculated set of features (SF) in association with an identifier (IdU) of the user in a database (PD). Then the controlling device receives data from the controlling node (CN), the data having been extracted from a message (Mes) intercepted by the controlling node (CN) after a deep packet inspection on the message, and calculates a set of features of the received data. If the calculated set of features matches a set of features stored in the database (PD), a notification message (Not) is sent to the user whose identifier (IdU) is associated with the stored set of features, the notification message containing an information that a match was found for the set of data of the user.</p> |
