Abstract

Un método para protección de información implementado por computadora comprende: determinar uno o más datos de entrada y uno o más datos de salida para una transacción, en donde los datos de entrada están asociados con los tipos de datos de entrada respectivamente, y los datos de salida están asociados con los tipos de datos de salida respectivamente; encriptar los tipos de datos de entrada y los tipos de datos de salida; comprometer cada uno de los tipos de datos de entrada encriptados y los tipos de datos de salida encriptados mediante un esquema de compromiso para obtener los valores de compromiso correspondientes; obtener al menos un parámetro R basado en al menos los valores de compromiso; y enviar la transacción a uno o más nodos en una red de cadena de bloques con la divulgación del parámetro R y sin revelar los tipos de datos de entrada ni los tipos de datos de salida para hacer que los nodos verifiquen la consistencia entre los tipos de datos de entrada y los tipos de datos de salida.
