  • Credit Card Number: Added support for RuPay and China UnionPay credit card patterns
  • Denmark personal identification number: Delimiter (hyphen or space) after 6 digits has been made optional to reduce false negatives
  • Germany identity card number: Updated the definition to adhere to the correct alphanumeric pattern as issued by the relevant authority (Ausweisnummer – Wikipedia); The definition now includes three confidence levels covering identity numbers issued before 2010 as well as issued after 2010.
  • Germany passport number: Updated the definition to adhere to the correct alphanumeric pattern as issued by the relevant authority (Ausweisnummer – Wikipedia); To reduce false negatives, also added a low confidence pattern which does not require mandatory keywords in proximity
  • New Zealand ministry of health number: Space is no longer needed between letters and digits; Removed keywords “health” and “treatment” from the keyword list
  • U.S. driver’s license number: Updated the patterns to include the new patterns being issued by different states
  • U.S. / U.K. passport number: Included the alphanumeric pattern of next generation passports which will be issued by U.S. Government going forward

What you need to do to prepare

Your existing policies (including DLP policies) need not be changed. If you are using Germany identity card number or Germany passport number SITs, you may change the confidence level within your policies including Data Loss Prevention, Communication Compliance, Sensitivity Labeling, and Records Management depending on the patterns you wish to detect in your policies. Please refer to the updated SITs definitions for more detail.
