¿Puede ocultarse información en una imagen de computador?
Downloads
Con la actual tecnología computacional es posible implementar técnicas de procesamiento de señales que permitan ocultar información dentro de archivos existentes. De esta manera es posible, por ejemplo, emplear un archivo gráfico para guardar un texto dentro de él sin que la imagen contenida en éste se dañe o se deteriore y con la ventaja de que el texto oculto puede recuperarse. Este tipo de procedimientos es útil en seguridad de redes y permitirá realizar transacciones seguras en la red Internet, entre otras aplicaciones. En este artículo se propone una técnica y se explica el programa prototipo que logra realizar esta tarea (programa implementado por estudiantes de la carrera de Ingeniería de Sistemas).
