Redacting Field Values

Monarch Data Prep Studio's redaction feature allows you to replace, or mask out field values, so that only a representation of the field value is displayed, and not the actual value.

For instance, you can redact Credit Card Numbers to look like this:

Actual Credit Card Number Value	Redacted Credit Card Number Value
1345-8716-4432-7892	xxxx-xxxx-xxxx-7892
3455-6457-3354-8875	xxxx-xxxx-xxxx-8875
0981-3245-1234-4456	xxxx-xxxx-xxxx-4456

This functionality is very useful for users who wish to share reports but need to hide actual data values, for example:

Analysts who wish to publish the results of their analysis of business data but must obscure any sensitive values.
Users experiencing problems with their reports or models who want to "sanitize” their reports via redaction before sending them to Altair Support for detailed analysis.

Monarch Data Prep Studio provides several redaction methods and you can select the best one to suit your requirements:

Method Name	Description	Sample Actual Value(s)	Redacted Value
X-over text	All characters are replaced with x. Note: You can only apply this method to columns with Text data type. Use a convert operation to convert your column values to text.	"Fred R. Persky "	[xxxxxxxxxxxxxxxxx]
X-over digits	All numeric characters are replaced by x. Note: You can only apply this method to columns of type text. Use a convert operation to convert your column values to text.	903-45-7654	xxx-xx-xxxx
X-over digits except last 4	All numeric characters except the last 4 are replaced by x. Note: You can only apply this method to columns of type text. Use a convert operation to convert your column values to text.	903-45-7654	xxx-xx-7654
X-over non-blanks	All characters except blanks are replaced with x. Note: You can only apply this method to columns with Text data type. Use a convert operation to convert your column values to text.	"Fred R. Persky "	“xxxx xx xxxxxx ”
