Structured checks such as country-specific ID checksums, ICAO 9303 MRZ check digits, Luhn, and IBAN mod-97 help control false positives.
When Lumask recognizes a passport or ID MRZ with a document boundary, it can suggest masking the entire document. For any other area, use manual rectangle, brush, or emoji masking.
Automatic detection runs across these categories. Lite automatically masks faces; Pro automatically masks every listed category.
