Disclosure Control SuperADMIN Macro
The following is a sample SuperADMIN macro that demonstrates the different confidentiality options that are available and how to configure them.
The macro creates a method for each of the rules. It then creates a folder in the database catalogue called Confidentiality Examples and adds multiple copies of the sample Retail Banking database into this folder, with each copy having a different rule applied to it.
This example is designed to allow you to compare the effects of each rule. For example, you could create the same table in SuperCROSS using each of these new databases and then compare them side by side to see how the different rules have different effects on the cross tabulation results.
You can download a copy of this macro from the Download Library. See the documentation on the macro
command for more details on how to play back a macro file in SuperADMIN.

# ConfidentialityRule.sam: Sets one or more random rounding rules.
# This macro sets up a method to apply one or more selected random rounding rules.
# The rules available are the same as those available in SuperCROSS via confid.ini,
# ie 0-3 Rounding,Random Rounding,1-4 Rounding and Graduated Rounding
# SA Configuration Options:
# set RULESET in confidentialityrule.dll with any reasonable combinations from the following values:
# NK(3,75)|FREQ(30)|0-3 Rounding|Random Rounding|1-4 Rounding|Graduated Rounding|THRESHOLD(300)
# Each rule must be separated by | and the rules specified in the property will be executed
# in the same sequential order as in the property value string.
# NK(3,75) is a concealment rule based on top n contributors. 3 and 75 are configurable.
# FREQ(30) is a concealment rule based on number of contributors. 30 is configurable.
# THRESHOLD(300) is a concealment rule based on the value itself. 300 is configurable.
# 0-3 Rounding,Random Rounding,1-4 Rounding and Graduated Rounding are existing rules in SX.
# Requirements:
# confidentialityrule.dll must exist in same directory as scsa.exe
# Removing methods in case they already exist
method "3,75" remove increfs
method F30 remove increfs
method "0-3" remove increfs
