Anonymize personal data with local AI and Cerewro

GDPR requires protecting personally identifiable information (PII). Cerewro detects and anonymizes names, IDs, emails, phones and financial data in documents and databases, generating the required processing activity record.

Category	Examples	Anonymization technique
Identifiers	Passport, NI number, SSN	Replace with generic ID
Contact	Email, phone, address	Pseudonymization / hash
Financial	IBAN, card number	Truncate (last 4 digits)
Health	Diagnoses, medications	Generalize / remove
Name	First and last name	Consistent pseudonym

Anonymize document folder for testing

Anonymize all documents in C:\data\customers\ to create a test copy without real data:
- Replace names with "PERSON_001", "PERSON_002"...
- Replace emails with "email_001@example.com"
- Replace phone numbers with "+44 000 000 0001"
- Maintain consistency: same real person → always same pseudonym
- Save anonymized docs to C:\data\customers-anonymized\
- Generate correspondence map in password-protected Excel
