DDI Data Description Statistics Protection Software

Owner: 
Description: 

It is a tool which enables easy anonymization processes of DDI standard univariate statistics. It was developed primarily to address the issue of statistical disclosure control for single variable aggregated data, publically distributed to particularly provide information to scientific researchers to promote detailed official statistics microdata use for scientific purposes. It enables quick and easy automatic data protection by performing data protection methods such as bracketing, top- and bottom-coding, variable (information) removal, numeric descriptive statistics protection and low frequency protection following the minimum frequency rule. In contrast to existing microdata and aggregated data anonymization tools, the developed software protects aggregated data directly in the XML code.

DBKfree

Description: 

The Data Catalogue (DBK) of the GESIS Data Archive holds study descriptions of all archived studies. The software DBKEdit for maintenance and DBKSearch for research in these holdings was developed by the GESIS Data Archive to make this service available. DBKEdit und DBKSearch are distributed as DBKfree to be used by others. Thus, interested users are able to describe their own catalogues on the basis of that and publish them on the web. (Sorry, DBKEdit is German only at the moment).
