Abstract

La presente invencion se refiere a un metodo de actualizacion de una base de datos (211) que comprende una huella digital de un conjunto de metadatos asociado, para cada uno de un numero de objetos multimedia. Un objeto multimedia y un conjunto de metadatos para el objeto multimedia es descargado de un cliente compartidor de archivos (101-105). Una huella digital es generada a partir del objeto multimedia, y la huella digital generada y el conjunto de metadatos obtenido, se incluyen en la base de datos (211). La base de datos (211) puede ser mantenida por un servidor central (210), o puede ser mantenida en una forma distribuida por servidores, (404) que se ejecuten en los clientes compartidores de archivos (101-105). La base de datos (211) en esta forma acumula muchos conjuntos de metadatos asociados con una huella digital particular. Cuando se ha recolectado un numero suficiente de conjuntos, se puede determinar un conjunto definido, usando tecnicas de filtracion.
