Abstract

Se proporciona un método y aparato para generar una identificacion digital que autoriza la informacion de una pluralidad de diferentes grupos de informacion. A la informacion de cada grupo se les separan los datos para producir una clave de eleccion arbitraria separada para cada grupo que autoriza la informacion en ese grupo. A las combinaciones particulares de las claves de eleccion arbitraria se les separan los datos conjuntamente para producir al menos una clave de eleccion arbitraria combinada. Cada una de las claves de eleccion arbitraria se combinan finalmente en un orden predeterminado con todas las otras claves de eleccion arbitraria a través de las claves de eleccion arbitraria combinadas para producir la identificacion digital en una manera que autorice la informacion de todos los grupos de informacion. La identificacion digital es reproducible sin acceso a todos los grupos de informacion autorizados por la misma. En su lugar, la informacion proveniente de un primer grupo de informacion se proporciona junto con un conjunto de claves de eleccion arbitraria y claves de eleccion arbitraria combinadas que incorporan la informacion autorizada proveniente de los otros grupos. La clave de eleccion arbitraria para el primer grupo de informacion se produce de manera local y se combina con las otras claves de eleccion arbitraria y/o claves de eleccion arbitraria combinadas con objeto de reproducir la identificacion digital.
