Customize Built-In Classifiers

As part of data classification in Microsoft 365 compliance center you can now customize built-in classifiers (sensitive information types) to meet organization's needs.

This update includes:

• Ability to edit custom dictionaries

• New validation functions like for example…:
• Custom checksum validator
• Date validator
• Luhn check (The Luhn algorithm will detect any single-digit error, as well as almost all transpositions of adjacent digits.)
• Etc.
• Ability to define Proximity at pattern and element level

Rollout will begin mid-June and is expected to be complete by mid-July 2021.
