Abstract
Se relaciona con un método y dispositivo para controlar la distribucion y uso de un trabajo digital almacenado junto con una informacion de derecho de uso adjunta en un portador de grabacion. La informacion de derecho de uso adjunta es encriptada o verificada mediante el uso de una informacion escondida que es cambiada en cada cambio de la informacion escondida que es cambiada en cada cambio de dicha informacion de derecho de uso. La informacion escondida puede ser una clave de encriptado usada para encriptar la informacion de derecho de uso, o una suma de control de un bloque de datos conteniendo la informacion de derecho de uso. Así, un ''ataque de copia y recuperacion'' no es exitoso, ya que conducirá a una falta de coincidencia entre la informacion escondida y la informacion de derecho de uso recuperada.
