Abstract

La presente se relaciona con un método para proteger información del usuario contra la manipulación. Para provee un alto nivel de protección contra cualquier tipo de manipulación sin aumentar en forma significativa el remanente se propone un método que comprende los siguientes pasos: -almacenar dicha información del usuario en paquetes de canal del usuario de una canal de usuario, - asignar información de estado a dichos paquetes de canal del usuario, dicha información de estado siendo usada para indicar si un paquete de canal del usuario ha sido manipulado y/o se encuentra inestable o no, y - almacenar dicha información de estado asignada a dichos paquetes de canal del usuario en un canal adicional oculto insertado en dicho canal del usuario, dicha información de estado asignada a un paquete de canal del usuario estando almacenado en el paquete de canal oculto asociado. También se relaciona con un método correspondiente para leer información del usuario.
