Abstract

Un metodo y un aparato para identificar un objeto que incluye codificar atributos fisicos de un objeto en donde la informacion codificada se utiliza por lo menos como un elemento para componer una marca de agua digital para el objeto; en otra modalidad, los atributos fisicos de un objeto se utilizan corno una clave para accesar a la informacion que se incluye en una marca de agua digital para el objeto; en una modalidad adicional, se incorpora una marca de agua digital dentro de un codigo de barras; como otro aspecto de esta modalidad, se puede codificar la informacion dentro de la marca de agua digital del codigo de barras y se puede decodificar o de otra forma recuperar mediante el uso de una clave; el codigo de barras marcado con agua digitalmente, puede funcionar de manera convencional o tambien puede incluir una "clave de paso" para permitir la lectura del codigo de barra en si.
