When manipulating sensitive data, such as names, addresses, credit card or social security numbers, you might want to to mask this data.

To protect the original data while having a functional substitute, you can use the Mask data (obfuscation) function.

Procedure

  1. Select the column on which you want to apply the data masking.
  2. In the Functions panel, type Mask data (obfuscation) and click the result to execute the associated function.

Results

The data in the column has been replaced by random but usable substitutes. Depending on the semantic type of the column on which you use the Mask data (obfuscation) function, the effect will vary. For more information, see Data Masking
