Randomization is another way to anonymize or de-identify personally identifiable information (PII) or protected health information (PHI).
FieldShield software in the IRI Data Protector suite provides simple access to non-reversible functions for:
- Random data generation - non-deterministic: replaces original field value with randomly generated data
- Random data selection - rarely deterministic: specific identifiers are pulled at random from the source, losing their association with other values in the original row
This simple dialog in the IRI Workbench GUI for FieldShield users can address any source file field or database column, along with other data masking functions:
Data shuffling is also possible through custom random functions or match logic you can define in the IRI Workbench expression builder. Many other data generation rules are exposed in Workbench as described here:
