The following types of masks retain the format of the original data:
Social Security numbers
Credit card numbers
Phone numbers
URL addresses
Email addresses
IP addresses
Social Insurance numbers
The Data Masking transformation replaces sensitive data with masked values in a realistic format. For example, when you mask an SSN, the Data Masking transformation returns an SSN that is in the correct format but is not valid.
When the source data format or datatype is invalid for a mask, the Integration Service applies a default mask to the data. The Integration Service applies masked values from the default value file. You can edit the default value file to change the default values.
