Abstract: front page image
(EN)The invention relates to a method of covertly transmitting information. The method comprises the step of providing biological sound data. Further, the method comprises the step of processing the biological sound data with the information to be transmitted in a correlated manner. The method also comprises the step of generating an acoustic signal from the processed biological sound data.
(FR)La présente invention concerne un procédé permettant de transmettre de l'information de façon dissimulée. Ce procédé consiste à se procurer de données de sons biologiques. Le procédé consiste ensuite à traiter les données de sons biologiques en corrélation avec l'information à transmettre. Le procédé consiste aussi à générer un signal acoustique à partir des données des sons biologiques qui ont été traitées.
