When manipulating sensitive data, such as names, addresses, credit card or social security numbers, you might want to mask this data.
To protect the original data while having a functional substitute, you can use the Mask data (obfuscation) function.
Procedure
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The data in the column has been replaced by random but usable substitutes.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 effects
