Find driver's license numbers in your files
FileSentinel finds driver's license numbers in documents and scans so this identity document number does not get shared by accident.
What it detects
What FileSentinel finds
FileSentinel detects driver's license number patterns alongside identifying context, using OCR to read them off scanned licenses and photos. Confidence and severity scoring keeps real license data above coincidental alphanumeric strings.
Where it hides
- Scanned IDs and PDFs (via OCR)
- Word documents and forms
- Spreadsheets and CSV exports
- Photos and screenshots (via OCR)
// RESULTS — findings scored by confidence and severity
Why it matters
The risk of leaked driver's license numbers
Driver's license numbers are widely used to verify identity, which makes them valuable for fraud. They show up in onboarding files, rental and insurance paperwork, and photographed IDs.
- HR onboarding and verification files
- Insurance, rental, and lease paperwork
- Photographed or scanned ID copies
- Forms and spreadsheets collecting ID details
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags driver's license numbers with a confidence and severity score, and helps you remediate. Built-in detectors cover the common cases, and a custom rule builder lets you add plain-text or regex detectors for anything specific to your work.
Score
Every finding gets a confidence and severity score, so real driver's license numbers rise above coincidental matches.
OCR
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching driver's license numbers in screenshots and scans.
Remediate
Redact values, mark false positives, or export a CSV, HTML, or PDF report, then share with confidence.
Private by design
Your files never leave your PC
Scanning, OCR, and remediation all happen on-device. FileSentinel makes no network connections to do its work, so the very data you are trying to protect never has to leave your machine to be checked. No server, no cloud, no upload step.
