Data pseudonymization

You can pseudonymize the data extracted by the SAP, JDBC, CSV, and Universal Messaging (Nirvana) extractors. The extracted data is pseudonymized before it is written to the output file as a source system event.

You can pseudonymize the source data using CTK. The Use pseudonymization during data extraction option is disabled by default but you can enable the option in the client properties in CTK. If you enable this option, CTK provides the Pseudonymization tab in the Data extraction component in the Process merge module. On this page, you can specify for each available source system attribute whether its value is to be pseudonymized or not.

Open a client in CTK -> Client properties -> Data sources -> Enable Use pseudonymization during data extraction.

For the data pseudonymization, CTK creates a required key and stores it in the pseudonymization.key file in the .../custom/<client>/keyfiles directory. The created pseudonymization.key file is of binary type.

Note that you must enable pseudonymization before any data for a source system attribute is extracted. Already imported cleartext data cannot be pseudonymized.

Warning

We recommend that you create a backup of the pseudonymization.key file. The key file cannot be restored and you cannot use another pseudonymization key instead.
