Identity reference data

The duplicate analysis process use reference data files called population files to evaluate the identity information in the input data. When you run a mapping with a Deduplicate transformation, the transformation compares the input data to the population file for the country in which the input data originates.
Data Quality downloads the population files to the Secure Agent host machine when you install the Secure Agent. You do not need to take any action to download the files.
You can review the location of the population files on the Administrator service.

Reviewing the Administrator properties for identity population data

You can review and configure the directory to which the Secure Agent downloads identity population files in the Administrator service. You can also review and configure the directories that the deduplication process uses for index and cache data.
