The coverage utility measure determines the extent to which data is effectively no longer available because of anonymization. For instance, if an anonymization method deletes a column of data, then that data is no longer available and the coverage score is reduced as a result. The tool is implemented in the python code gdaUtility.py, found in the repo https://github.com/gda-score/utility. The same tool also provides a simple measure of accuracy.
