Abstract

Se divulgan un método y sistema para utilizar marcas de agua en sistemas de comunicacion. Las marcas de agua son típicamente pequenas cantidades de datos auxiliares incorporados en una senal de cobertura. La senal de cobertura es la senal de comunicacion primaria, y puede consistir en bits binarios, símbolos de valores multiples, formas de onda analogica, o cualquier otro tipo de senal de comunicacion primaria. Se divulgan indicacion de intensidad de seguridad, seguimiento de ubicacion, deteccion de intrusion y transmision de informacion que no es de seguridad utilizando marcas de agua, junto con un sistema para gestionar marcas de agua.
