Random masking consists of masking an input value with a randomly generated value.

When there are multiple occurrences of the same value in the input dataset, it can be masked with different values.

Different values from the input dataset can be masked with the same value.

For example, the following diagram shows an example of how the tDataMasking component can mask data randomly:
  • The A value is masked with D when it first appears in the input dataset.
  • The B and C values are masked with E.
  • The A value is masked with F when it appears in the input dataset for the second time.
