Find dates of birth in your files
FileSentinel finds dates of birth that, combined with a name, become identifying personal data you may be obligated to protect.
What it detects
What FileSentinel finds
FileSentinel detects dates of birth across common formats and weighs them against nearby personal identifiers, so a DOB attached to a person scores higher than an ordinary calendar date. Findings are ranked by confidence and severity.
Where it hides
- Spreadsheets and CSV exports
- Word and PDF forms
- Text and email exports
- Scanned forms (via OCR)
// RESULTS — findings scored by confidence and severity
Why it matters
The risk of leaked dates of birth
A date of birth alone is low risk, but paired with a name or other identifier it becomes part of a profile useful for identity theft and is regulated personal data under privacy laws.
- HR and benefits records
- Customer and patient intake forms
- Membership and registration spreadsheets
- Scanned applications and forms
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags dates of birth 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 dates of birth rise above coincidental matches.
OCR
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching dates of birth 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.

Questions & answers
Find dates of birth FAQ
How do I find dates of birth in my files on Windows?
Install FileSentinel from the Microsoft Store, point it at a folder or drive, and start a scan. FileSentinel reads inside your files, flags dates of birth, and scores each finding by confidence and severity so the real risks rise to the top.
Is scanning for dates of birth private?
Yes. FileSentinel runs entirely on your device. Scanning, OCR, and remediation all happen locally with no uploads and no cloud, so the data you are trying to protect never has to leave to be checked.
Will FileSentinel flag every date as a date of birth?
No. It scores dates by context, so a date next to a name, age, or birth label ranks as a likely date of birth, while ordinary calendar dates stay low. You can tune what matters with custom rules and Crown Jewels.
What file types does FileSentinel check for dates of birth?
FileSentinel reads inside documents, spreadsheets, text, and PDFs, and with OCR enabled it reads text inside images and scanned PDFs too, so dates of birth captured in a screenshot or scan is caught as well.
