How to Create Negative Detection Patterns

Have you ever experienced a false positive before? Was it a tracking number that resembled a credit card number? With Negative Detection Patterns, you can effectively exclude these numbers from Blackthorn Compliance detection. All you need to do is create your own patterns for international phone numbers, UPS, USPS, Fedex, and other common false positives numbers.

Important:

• Numbers matched with Negative Patterns are not masked nor are logs created. No action is the correct action for Negative Patterns.
• It is possible for a record to have both valid credit card numbers and false positives.
• It is also possible for the same number to be both a valid credit card number and a false positive.
