Abstract

La presente invención se refiere a un método y un sistema (20) para inserción de marca de agua en un contenido de medios digitales (1) recibido por un software de aplicación (APP) en forma de por lo menos una muestra cifrada (15). El contenido de medios digitales (1) se relaciona con los metadatos (10) asignados a cada muestra (15). Esta última está cifrada por medio de una clave de muestra (Kc'). Los metadatos (10) contienen primeros datos (11), segundos datos (12) y una firma digital (13) resultante de la firma de dichos primeros y segundos datos. Los primeros datos (11) contienen por lo menos una clave de contenido (Kc) y metadatos de inserción de marca de agua (WM) y por lo menos dichos primeros datos (11) están cifrados mediante una clave de transporte (KT). Los segundos datos (12) contienen un vector de inicialización (IV) de manera que el contenido clave (Kc) y el vector de inicialización (IV) forman un par único de datos criptográficos equivalentes a la clave de muestra (Kc'). El software de aplicación (APP) se comunica con un entorno seguro (30) a cargo del manejo de dichos metadatos (10). La inserción de marca de agua del contenido de medios digitales (1) se realiza mediante los siguientes pasos: - dar instrucciones al software de aplicación (APP) para que extraiga los metadatos (10) del contenido de medios digitales (1), antes de transmitir los metadatos (10) al entorno seguro (30). - descifrar por lo menos una parte de los primeros datos (11) por medio de la clave de transporte (KT), - verificar la autenticación de dichos datos firmados digitalmente (11, 12) y en el caso de un resultado positivo, transmitir entonces la clave de contenido (Kc) y el vector de inicialización (IV) a un decodificador (37) y transmitir los metadatos de inserción de marca de agua (WM) a una unidad de inserción de marca de agua (39). - transmitir el contenido de medios digitales (1) al decodificador (37) para descodificar cada muestra (15) por medio de dicho par de datos criptográficos, - transmitir cada muestra descodificada (15') a la unidad de inserción de marca de agua (39) para marcarla digitalmente por medio de por lo menos dichos metadatos de inserción de marca de agua, - transmitir la muestra (15', 15") desde la unidad de inserción de marca de agua (39) hacia el software de aplicación (APP) o a una ruta de medios segura para fines de renderización.
