Prototype implementations of Census 2021 protection methods

For the protection of tables resulting from the population Census 2021, two methods (Targeted Record Swapping and noise addition using Cell Key Method) were proposed in a project partly funded by Eurostat. For more information on that project go to the projects website.

As a follow up, prototype implementations of the two proposed methods were made available to be tested by the Census community (and others that might be interested).
Finally, the methods are implemented in μ-ARGUS, τ-ARGUS as well as in R (scripts and packages) and are available through the Open Source website. Note that the versions of μ-Argus and τ-Argus as mentioned on this page contain the Targeted Record Swapping and Cell Key Method as well.

You can find executables, installation instructions and quick references targeted to the Census community via sdcTools on GitHub in the CensusProtection repository.
