The Data Dictionary validation type allows you to discover sensitive data using predefined lists of values. This method reduces false positives, which can sometimes occur with regular expressions. There are 6 predefined dictionaries in Kron DAM (English Firstname-Lastname, Russian Firstname-Lastname, and Turkish Firstname-Lastname)

One key feature of the Data Dictionary is that it performs **case-insensitive** searches, meaning that it matches values regardless of whether they are in uppercase or lowercase.
