Strategies are described for sanitizing a data set, having the effect of obscuring restricted data in the data set to maintain its secrecy. The strategies operate by providing a production data set to a sanitizer. The sanitizer applies a data directory table to identify the location of restricted data items in the data set and to identify the respective sanitization tools to be applied to the restricted data items. The sanitizer then applies the identified sanitization tools to the identified restricted data items to produce a sanitized data set. A test environment receives the sanitized data set and performs testing, data mining, or some other application on the basis of the sanitized data set. Performing sanitization on a sanitized version of the production data set is advantageous because it preserves the state of the production data set. The data directory table also provides a flexible mechanism for applying sanitization tools to the production data set.
