Aadhaar Masking

Documents & Biometrics

Automatically mask the first eight digits on Aadhaar images and PDFs.

About this API

Storing unmasked Aadhaar copies is a compliance risk. The Aadhaar Masking API detects the number on the document, in any orientation and on both sides, and returns a masked copy ready for storage, with a confidence flag when manual review is advisable.

Use it at every intake point, from candidate uploads to email attachments, so the compliant version is the only version.

Typical uses

Candidate document uploads. Mask before the file is attached to the case.
Email and WhatsApp intake. Clean attachments received over messaging channels.
Archive remediation. Mask legacy copies already in storage.
Account opening. Compliant KYC document handling.

Questions

Is the unmasked copy retained?: No. The original is processed and purged; only the masked output is returned.
Does it work on photocopies and photos?: Yes. Scans, photocopies, phone photos and PDFs are supported.
