Mask format

Mask format

When you configure key or random masking for string data type, configure a mask format to limit each character in the output column to an alphabetic, numeric, or alphanumeric character.
If you do not define a mask format, the Data Masking transformation replaces each source character with any character. If the mask format is longer than the input string, the Data Masking transformation ignores the extra characters in the mask format. If the mask format is shorter than the source string, the Data Masking transformation does not mask the characters at the end of the source string.
When you configure a mask format, configure the source filter characters or target filter characters that you want to use the mask format with.
The mask format contains uppercase characters. When you enter a lowercase mask character, the Data Masking transformation converts the character to uppercase.
The following table describes mask format characters:
Character
Description
A
Alphabetical characters. For example, ASCII characters a to z and A to Z.
D
Digits. From 0 through 9.
N
Alphanumeric characters. For example, ASCII characters a to z, A to Z, and 0-9.
X
Any character. For example, alphanumeric or symbol.
+
No masking.
R
Remaining characters. R specifies that the remaining characters in the string can be any character type. R must appear as the last character of the mask.
For example, a department name has the following format:
nnn-<department_name>
You can configure a mask to force the first three characters to be numeric, the department name to be alphabetic, and the dash to remain in the output. Configure the following mask format:
DDD+AAAAAAAAAAAAAAAA
The Data Masking transformation replaces the first three characters with numeric characters. It does not replace the fourth character. The Data Masking transformation replaces the remaining characters with alphabetic characters.
