Data Classification Verification Algorithms

You can use verification algorithms in a Data Classification policy object of type Regular Expression to filter the regular expression results. This will enforce additional restrictions and validations on matched phrases. The verification algorithm will take as an input each one of the data classification policy objects’ regular expression match result strings, and will remove results that do not meet the criteria defined within the algorithm.

Data Access Security comes with a set of verification algorithms out of the box for standard verifications, such as Luhn, for credit card numbers or SSN algorithms. In addition, you can write a verification algorithm, upload it to the Data Access Security website, and use it in data classification policy objects.

Out of the Box Verification Algorithm

Verification algorithms for common rules are pre-loaded:

  • Luhn (Credit Card Number)
  • US SSN
  • Netherlands BSN
  • Israeli ID
  • IBAN
  • South African ID

The dropdown list of verification algorithms in the Rule Criteria screen includes out of the box algorithms, as well as algorithms uploaded by the user.
