The Person Last Name Mask
This mask shall generate last names, such as "Smith", "Jones", etc.
The longest Last Name is 13 characters. If a receiving column width is shorter than a generated Last Name then the Last Name shall be truncated.
Every Last Name consists of only alphabetic characters. In other words, there are no hyphenated names, and there are no apostrophes. For example, the last name O'brien would be generated as "Obrien".
Here you can specify the size of the pool of distinct Last Names that shall be used to generate values.
During a masking Run, these names are uploaded during the Setup phase into a temporary table on the database being masked. It can take approximately 1 second per 10,000 names to upload. Therefore, if you choose to use 'All' Last Names then you can expect to wait an additional minute or two during the Setup phase.
The default is 10,000 of the most popular Last Names in the United States.
The maximum available is 88,800. You can also specify a custom value from 10 to 88,800.
Case of new names
Specifies the case of the masked values to be generated.
For example, "Smith" is in Title Case, "SMITH" is in Upper Case and "smith" is in Lower Case.
Note: The case of the original name is not relevant for the selection of the masked name. For example, if the original name is "smith" and the masked value is "Jones", then the masked value for "Smith" and "SMITH" shall also be "Jones" (assuming that Deterministic mode masking is used.)
If this mask is performed in Deterministic mode, then the results will be deterministic for a given 'Select from' value (in addition to any Deterministic Seed key, as usual).
If you want the masked results to be the same for each Run on the same input, then the 'Select from' value must also be the same on each Run.
