Database Anonymization

Configurable and super fast

WARNINGS

Don't use on a production (live) environment, use on a copy eg. test environment
Anonymizes the database in-place
Anonymization is irreversible, cannot be undone

About

A database which contains sensitive data, like personal- and userdata, should be anonymized when:

  • Sending and/or sharing a database with external parties (eg development agencies, freelancers).
  • On a test environment accessible to external (or untrusted) parties, or when it doesn't have the high security level like a production environment.

Database anonymization is the required action to prepare such database.
So you don't risk to infringe GDPR (dutch: AVG), privacy and other concerns about sensitive data.

To anonymize a PostgreSQL database, some nice tools and libraries are available. Convenience, configuration and advanced features are key here!
With this Odoo module/app you're able to prepare (configure) the database and execute the anonymization.

Features

Subject Description
Super fast anonymization Handles very large databases.
Uses the PostgreSQL COPY command by psycopg2.
Anonymization technology (tool) Anonymization is done by the excellent (Python) pganonymize tool/library.

(i) https://python-postgresql-anonymizer.readthedocs.io/en/latest/index.html
Update Models and Fields A wizard to select models, which loads (and updates) the models and all its fields into configuration models.
Configure Fields Configure per field, whether to anonymize and the anonymization method.
Configure Models Configure per model, which records to anonymize or to exclude, by a search domain filter (or SQL WHERE).
If empty search domain filter, all records will be anonymized.
Field anonymization methods Alter data with plentiful of Provider tools
(i) https://python-postgresql-anonymizer.readthedocs.io/en/latest/schema.html

Possibilities:
  • clear: set database field to NULL.
  • choice: define a list of possible values for a database field and will randomly make a choice from this list.
  • fake: use providers from the Python library Faker
    (i) https://faker.readthedocs.io/en/master/providers.html
  • md5: hash the given field value with the MD5 algorithm.
  • mask: replace each character with a static (configured) sign.
  • set: replace with configured value.
  • append: append a value at the end of the altered value.
CSV export/import template for model and fields configuration CSV export/import template is included, for models and fields configurations.
This eases preparation, re-use and repeatability of the anonymizer configuration, also across databases.
See an example in the screenshots below (CSV export template, CSV import).
Enable anonymization setting (extra safety) Initially the database anonymization is disabled and only configuration (model fields) is possible.
Database anonymization can be enabled in the Configuration Settings.
Database transaction and error reporting The anonymization runs in a database transaction. If an error occurs eg due to misconfiguration, the transaction is rolled back and the error is displayed to the user.
Non feature notice: filestore (attachments) The filestore (attachments) ain't anonymized, altered or whatsoever.
So the anonymization only applies to the (PostgreSQL) database.
Installation requirement #1: Model Fields configuration
  • pip3 install pyyaml
Installation requirement #2: Database Anonymization
  • pip3 install pganonymize
  • pip3 install Faker

Releases

1.5

  • Improvements for CSV export/import for "Config State" field:
    - Remove readonly setting from "Config State" field in model. It's readonly in views.
    This ensures the Config State can be imported.
    - Add "Config State" field to CSV export template.

1.4

  • CSV export/import template: Add external ID (nova.anonymizer.model record).

1.3

  • Fix table determination (computed field). Bug introduced in version 1.1.
  • Move Contact res.partner configuration to demo data (xml).

1.2

  • CSV export template (models and fields configurations).
  • Change some fields options (ondelete, required) to improve CSV import.

1.1

  • Add (import) template CSV file, to ease the setup to import models and fields configurations.
    File in module directory:data/example_import_template_nova.anonymizer.model.csv
  • Remove table field, don't store anymore (of course implicit on the model).

1.0

  • Improvements and documentation in the anonymize wizard view.

0.8

  • Fix Anonymizer Field config: when Provider (field) is cleared, update Config State (field) to "Check", instead of empty (NULL).

0.7

  • Fix: SQL literals (eg. strings) encoding of search domain (introduced in 0.5).
  • New feature: Configure whether to exclude (is new) or include (introduced in 0.5) records to be anonymized, by domain or SQL WHERE-clause.
  • Improvements: renaming of menu's, windows, buttons.

0.6

  • Improvement: search domain (introduced in 0.5), to also query inactive records (with_context(active_test=False).

0.5

  • New feature: Configure per model a search domain or SQL WHERE, which generates the schema to filter records to anonymize.
    This change required to add the nova.anonymizer.model (model), where the search (domain, WHERE) can be setup.

0.4

  • Improvement: Cleanup of Model Fields Configuration (nova.anonymizer.model.field) upon updating (write).

0.3

  • Use --host and --port options if set in the Odoo config.

0.2

  • Path determination of the pganonymize tool.
