Overview

The PII Finder scans text or log files to detect and annotate personally identifiable information (PII) such as email addresses, phone numbers, and credit card numbers. It outputs a JSON report with the positions and types of detected PII, aiding in redaction and compliance checks.

When to use

When auditing text or logs for sensitive personal data before sharing or processing.
To ensure compliance with privacy regulations like GDPR by identifying PII in datasets.
When anonymizing data for testing or analysis to prevent exposure of real personal information.

How it works

1Input the text or log content into the text area.
2Select the types of PII to scan for, such as emails, phones, or credit cards, from the dropdown.
3Optionally, enable context inclusion to see surrounding characters for each match.
4The tool processes the input and returns a JSON object listing all detected PII with their types and positions.

Use cases

Scanning server logs to identify and redact IP addresses and API keys for security audits.
Checking customer support transcripts for email addresses and phone numbers before archiving.
Validating data exports to ensure no credit card numbers or SSNs are included for compliance.

Examples

1. Audit Email Logs for PII

Security Analyst

Background

A security analyst needs to review email server logs to ensure no sensitive information is exposed.

Problem

Manually scanning logs for email addresses and phone numbers is time-consuming and error-prone.

How to use

Paste the log content into the text input, select 'email' and 'phone' from the scan types, and include context for better analysis.

scanTypes: ["email", "phone"], includeContext: true

Outcome

The tool returns a JSON report highlighting all email addresses and phone numbers found, with their positions and surrounding context.

2. Redact Credit Cards from Documents

Data Privacy Officer

Background

Before sharing a document externally, a data privacy officer needs to remove any credit card numbers.

Problem

Credit card numbers might be embedded in text, and manual redaction risks missing some.

How to use

Upload or paste the document text, choose 'creditCard' in the scan types, and run the scan.
