Pseudonymizing Data

Using CData Sync, data fields can be pseudonymized during extraction. This way, sensitive data fields can be hashed at the source before it reaches the Process Mining product. Follow these steps to pseudonymize data.

  1. Go to the desired task of a job in CData.
  2. Edit the query.
  3. Add the hashbytes() function to each field that needs to be pseudonymized. For example

    REPLICATE [SOURCE_TABLE] SELECT hashbytes('SHA2_256',[SOURCE_FIELD]) AS [DESTINATION_FIELD] FROM [SOURCE_TABLE];

    This way, all values will be hashed with a SHA2 256 hash. For more information, see SHA-2. If desired, the hashed values can be transformed into values like "Person 1", "Person 2", "Person 3" by writing SQL queries for this in the data transformations.
