Database Anonymizer

Database Anonymizer is a tool written in GO that allows anonymizing or deleting data from a MySQL or PostgreSQL database.

It addresses various use cases such as providing developers with an anonymized copy of a database or satisfying the need to anonymize or delete data in accordance with GDPR (General Data Protection Regulation), depending on the retention periods defined in the processing register.

The project includes a vast array of fakers. It also enables data generation via Twig-written templates. You can specify precise rules for each table or global rules applied to all tables in your configuration.

Usage

Configuration

The configuration is written in YAML. Here's a complete example:

rules:
  columns:
    phone: phone_e164number
  generators:
    person_name: [display_name]
  actions:
    - table: user
      virtual_columns:
        domain: internet_domain
      columns:
        firstname: person_firstname
        lastname: person_lastname
        email: "{{ (firstname ~ '.' ~ lastname ~ '@' ~ domain)|lower }}"
    - table: company
      columns:
        name: company_name
    - table: access_log
      query: 'select * from access_log where date < (NOW() - INTERVAL 6 MONTH)'
      delete: true
    - table: user_ip
      primary_key: [user_id, ip_id]
      delete: true

Run

To display help, use -h:

database-anonymizer -h

Here are examples for MySQL and PostgreSQL:

database-anonymizer --dsn "mysql://username:password@tcp(db_host)/db_name" --schema ./schema.yaml
database-anonymizer --dsn "postgres://postgres:postgres@localhost:5432/test" --schema ./schema.yaml
