  "Description": "Tabular data from statistical institutes and agencies are\nmostly confidential and must be protected prior to\npublications. The cell-key method is a post-tabular Statistical\nDisclosure Control perturbation technique that adds random\nnoise to tabular data. The statistical properties of the\nperturbations are defined by some noise probability\ndistributions - also referred to as perturbation tables. This\ntool can be used to create the perturbation tables based on a\nmaximum entropy approach as described for example in Giessing\n(2016) <doi:10.1007/978-3-319-45381-1_18>. The perturbation\ntables created can finally be used to apply a cell-key method\nto frequency count or magnitude tables.",
