En la estadística oficial los métodos de Control de Divulgación Estadística (SDC) están adquiriendo una importancia creciente, debido al aumento de la disponibilidad de nuevas fuentes de información y de la necesidad de producir y difundir información más desagregada. Estos métodos están enfocados en el control del riesgo de revelación de datos, garantizando un nivel aceptable y minimizando el impacto en la difusión de información. El IECA emplea habitualmente métodos SDC no perturbativos, de supresión, para proteger los datos poblacionales difundidos en malla de 250m x 250m.

En este trabajo, se explora un método SDC alternativo, de perturbación de datos, para difundir información protegida del Catastro en celdas regulares de 250m de lado. El método se basa en la utilización de la información de las celdas vecinas como apoyo para obtener un número de observaciones mayor en aquellos casos que presentan riesgo de revelación individualizada de datos sensibles.

Keywords: Control de Divulgación Estadística (SDC), métodos perturbativos, malla estadística
