About The Book

La st�ganographie est une forme de dissimulation de donn�es; il s'agit d'un moyen de prot�ger des informations en int�grant des donn�es dans des supports num�riques � des fins d'identification, de protection des droits d'auteur et d'envoi de messages secrets. La st�ganographie audio constitue un domaine particuli�rement complexe, car le syst�me auditif humain (HAS) est extr�mement sensible. L'un des principaux d�fis de la dissimulation de donn�es dans les fichiers audio consiste � d�velopper un syst�me capable d'int�grer une grande quantit� de donn�es sans nuire � la qualit� sonore. Dans le cadre de cette recherche, deux approches de st�ganographie ont �t� con�ues pour dissimuler des donn�es secr�tes dans un fichier multim�dia audio (MP3). La premi�re m�thode propos�e repose sur l'int�gration de texte chiffr� entre les trames (BF) d'un fichier MP3, tandis que la seconde repose sur l'int�gration de texte chiffr� avant la premi�re trame (BAF) d'un fichier MP3. Apr�s avoir examin� les deux approches propos�es, il a �t� confirm� que la premi�re m�thode (BF) est la plus performante, car elle permet d'int�grer environ 40 Mo sans alt�rer la qualit� sonore et n�cessite 134,2 secondes pour l'int�gration et 2 618,2 secondes pour l'extraction, tandis que la deuxi�me m�thode (BAF) a d�montr� sa capacit� � int�grer environ 8 Ko (au maximum) sans alt�rer la qualit� sonore.
