Invisible forensic watermarks that identify who leaked your data
Each recipient's copy of an email, document or image carries a different hidden mark, so a single leaked artifact points to one person.
The Luma image mark is engineered to survive printouts, photocopies, mobile photos and compression, where metadata-based tagging fails.
Marks everything shown on a display, covering any app or file type including browsers, collaboration tools and AI assistants.
Upload a leaked file, screenshot or photo and get back the source recipient with a confidence score and chain-of-custody documentation.
