Anonymizer

Anonymizer is a universal tool to create anonymized DBs for projects.

Why is it so important to work with anonymized databases? In the development process, you should never use your production database - it is risky and against the law. Working with a production database in development is risky, because by some mistake, you can might make your clients data available to the whole world. In our world, general data is one of most valuable things and EU tries to protect citizens' general data via the General Data Protection Regulation (GDPR).

Some more quick wins for GDPR? Take a look at our recent blog post.

How does Anonymizer work?

Anonymizer replaces all data in your database by anonymized random data. The most important feature of Anonymizer is data formatting. All generated data is similar to the original data used by real users. The example below shows anonymized data in a Magento 1 sales_flat_quote_address table.

Requirements

ruby >= 2.2
mysql >= 5.6

Supported frameworks

Magento 1.9.x / 2.x
Pimcore 4 / 5
Sylius 1.0.0-beta.2

Of course you can anonymize any other database - this is just an example.

Getting started

Clone this repository and add a configuration file for your first project to the config/project/ directory.

Configuration file

File name

The file name reflects the anonymized database's name. For example, if you need to anonymize a db dump named example.sql.gz, the configuration file should be named example.json.

Basic configuration

Project type

Project configuration files always have an extended type. In the project configuration file, you have to set the type and basic_type which is connected with the supported framework. Only framework configuration files use the basictype.

Available basic types

custom
magento_1_9
magento_2_0
pimcore_4
pimcore_5
sylius

Change anonymized file's name

The anonymized dump is given the same name as the original database dump file. If you want to change this name, you can set the key random_string in configuration file - the value of this key will be added to end of the filename. In the example below, the output file will be named example_ba74a64a152b84ec004d03caba15ba95.sql.gz.

Example

{
    "type": "extended",
    "basic_type": "magento_1_9",
    "random_string": "ba74a64a152b84ec004d03caba15ba95",

Database dump location

Anonymizer can work with both locally and remotely stored database dumps. Database dumps from remote servers are downloaded by rsync.

Working with local database dump

In the example below, the database dump file is in the /path/to/database/dump/ directory.

"dump_server": {
    "host": "",
    "port": "",
    "user": "",
    "path": "/path/to/database/dump/"
}

Working with remote database dump

In the example below, the database dump file is stored on a remote server with an IP address of 1.2.3.4 and ssh port of 5022. The ssh user's name is anonymizer, the directory on remote host with the database dump is /path/to/database/dump/. In this case, let's assume that we need to add --rsync-path=\"sudo rsync\" option to our rsync dump download command.

"dump_server": {
    "host": "10.15.4.254",
    "user": "anonymizer",
    "port": "5022",
    "passphrase": "",
    "path": "/media/drbd0/backup/sqldump/sqldump",
    "rsync_options": "--rsync-path=\"sudo rsync\""
}

Tables to anonymization

Anonymizer can replace the original data by anonymized entries or truncate the data in the destination table.

Available types of data

Simple types

firstname
lastname
login
email
telephone
company
street
postcode
city
full_address
vat_id
ip
quote
website
iban
json

Special types

uniq_email - unique email address, because of bug in mysql, anonymizer can't generate uniq email address based on email and some uniqeu value form UUID mysql methiod
uniq_login - unique login
regon - Polish REGON number with validation
pesel - Polish PESEL number with validation

How to replace data in a table?

In the example below, data in the user_address table will be replaced by new, anonymized data. The example database contains a user_address table with the following columns - firstname, lastname, postcode, address, city, email, phone, company, vat_id. We will replace all columns' contents with some valid data, consistent with its previous type.

"tables": {
    "user_address": {
        "firstname": {
            "type": "firstname",
            "action": "update"
        },
        "lastname": {
            "type": "lastname",
            "action": "update"
        },
        "postcode": {
            "type": "postcode",
            "action": "update"
        },
        "address": {
            "type": "street",
            "action": "update"
        },
        "city": {
            "type": "city",
            "action": "update"
        },
        "email": {
            "type": "email",
            "action": "update"
        },
        "phone": {
            "type": "telephone",
            "action": "update"
        },
        "company": {
            "type": "company",
            "action": "update"
        },
        "vat_id": {
            "type": "vat_id",
            "action": "update"
        }
    }
}

How to truncate data in a table?

In the example below, the data in the log_customer table will be truncated.

"tables": {
    "log_customer": {
        "only_truncate": {
            "action": "truncate"
        }
    }
}

How to empty only selected columns in a table?

In the example below we will empty data in column with configuration values, keeping other columns intact.

"tables": {
    "some_configuration_table": {
        "config_value": {
            "action": "empty"
        }
    }
}

How to set static value to a column?

In below example value PLN will be assigned to column base_currency for all users.

"tables": {
    "users": {
        "base_currency": {
            "action": "set_static",
            "value": "PLN"
        }
    }
}

How to use Anonymizer with Magento EAV?

Anonymizer can also work with Magento's EAV model. In the example below, the customer attribute about_me in the customer_entity_text table will be replaced with a random phrase.

"tables": {
    "customer_entity_text": {
        "value": {
            "action": "eav_update",
            "attributes": [
                {
                    "code": "about_me",
                    "type": "quote",
                    "entity_type": "customer"
                }
            ]
        }
    }
}

How to work with JSON data

Anonymizer can now update values of JSON encoded data. In below example we anonymize json stored in additional_data column. You should familiarize with MySQL JSON path expressions.

{ "id": 123, "user": { "first_name": "John", "last_name": "Smith", "phone": "123-456-789" }, (...) }

"tables":{
    "subscriptions":{
        "additional_data":{
            "action":"json_update",
            "fields":[
                {
                    "path":"$.user.first_name",
                    "type":"firstname"
                },
                {
                    "path":"$.user.last_name",
                    "type":"lastname"
                },
                {
                    "path":"$.user.phone",
                    "type":"telephone"
                }
            ]
        }
    }
}

How to run custom queries

Anonymizer can run custom, row queries before and after anonymization process. In the example below, the anonymizer runs two queries before and one after.

"tables": {
},
"custom_queries": {
    "before": [
        "DELETE FROM some_column WHERE date > '2019-12-25'",
        "INSERT INTO some_column2 SET table = 'value'"
    ],
    "after": [
        "INSERT INTO some_column SET name = 'admin', pass = '1234567890'",
    ]
}

Example configuration file

{
    "type": "extended",
    "basic_type": "magento_1_9",
    "random_string": "ba74a64a152b84ec004d03caba15ba95",
    "dump_server": {
        "host": "10.15.4.254",
        "user": "anonymizer",
        "port": "5022",
        "passphrase": "",
        "path": "/media/drbd0/backup/sqldump/sqldump",
        "rsync_options": "--rsync-path=\"sudo rsync\""
    }
    "tables": {
        "user_address": {
            "firstname": {
                "type": "firstname",
                "action": "update"
            },
            ...
        },
        "log_customer": {
            "only_truncate": {
                "action": "truncate"
            }
        },
        "customer_entity_text": {
            "value": {
                "action": "eav_update",
                "attributes": [
                    {
                        "code": "about_me",
                        "type": "quote",
                        "entity_type": "customer"
                    }
                ]
            }
        },
        "subscriptions":{
            "additional_data":{
                "action":"json_update",
                "fields":[
                    {
                        "path":"$.user.first_name",
                        "type":"firstname"
                    },
                    {
                        "path":"$.user.last_name",
                        "type":"lastname"
                    },
                    {
                        "path":"$.user.phone",
                        "type":"telephone"
                    }
                ]
            },
            "comment": {
                "type": "quote",
                "action": "update"
            }
        }
    }
