Avoid fingerprinting uninteresting/irrelevant values

Some database tables/CSV files may contain values that should be ignored and excluded from fingerprinting. For example, a table may contain a value of 'N/A' instead of valid SSN. Looking through incidents (after the data was fingerprinted), you may locate additional candidates for ignoring.

The validation script template (described under Creating a validation script section) allows you to ignore values that are specified in an external “ignored dictionary” file. If preferred, you can write your own scripts that filter any custom type of irrelevant data.
