KVKK / GDPR Data Masker: method and usage
Finds common personal-data patterns with regular expressions and replaces them with readable placeholders. It does not guarantee legal compliance; human review remains essential.
synthetic or minimized code, configuration, identifiers, or file content you are authorized to review Confirm the shape first with a small example containing no personal data.
evidence locations, severity, false-positive considerations, and the next verification action
Practical steps
- Paste text into this browser tab.
- Run masking and review detected types.
- Manually verify missed or incorrect replacements.
manual review at the source location and independent verification with an appropriate professional security tool or authorized process
Pattern-based masking does not prove that all personal data was found or that KVKK/GDPR duties are met; a human must review the field inventory, re-identification risk, and sample output.
Suitable use cases
- Anonymizing support tickets
- Preparing sample data
- Pre-sharing document checks
Worked decision record
Replace email, phone, IBAN, and IP values with visible placeholders before sharing a support ticket with developers.
Use a fully synthetic record: `Ada Test`, `[email protected]`, `+90 555 000 00 00`, a sample IBAN, and `192.0.2.10`; include an order number on the same line.
Sensitive patterns become type-labelled placeholders while the order number and issue description remain. The before/after view shows no unintended context loss.
Do not share if a real name, an indirect identifier in free text, or an organisation-specific customer number remains visible; complete the field inventory manually.
