Output checking is the process of checking the disclosure risk of research results based on microdata files made available in the remote access systems. Output control is a vital tool for the National Statistical Institutions (NSIs). It is used to monitor that the rules laid down in the security agreement are kept by the researchers. In Nordic projects, all outputs are controlled by the data hosting NSI.
