Optical Character Recognition (OCR) makes capturing identity documents and card numbers effortless. But sending high-resolution photos of government IDs to cloud APIs introduces immense identity theft risks. Here is how Vaulta solves it on-device.
Google ML Kit: Local Vision Neural Models
Vaulta bundles the Google ML Kit Vision library. When you point your camera at a driver's license, passport, or utility bill:
- The camera buffer is processed entirely in your phone's local CPU / NPU memory.
- Neural text recognition executes on-device in under 50 milliseconds.
- Relevant fields (names, dates, ID numbers) are extracted and populated into your vault fields.
- The raw camera image buffer is immediately flushed from volatile memory unless you choose to save it as an encrypted attachment.
Guaranteed Zero Cloud Leakage: At no point during the scan is any image or extracted text transmitted across the network.
Smart Pattern Recognition
Vaulta includes local regex parsers for standard identity formats, MRZ (Machine Readable Zone) lines on international passports, and Luhn-algorithm validation for credit cards, ensuring error-free data entry.
