README

Laravel Database Anonymize is a package designed to streamline data anonymization, enabling organizations to safeguard privacy, comply with regulations, reduce the risk of data breaches, and share data securely.

Key Benefits:

1. Privacy Protection
   Anonymization removes or masks sensitive personally identifiable information (PII) such as names, addresses, emails, and phone numbers, preserving individuals' privacy.

2. Regulatory Compliance
   Meet legal and industry standards like the EU's General Data Protection Regulation (GDPR) by anonymizing sensitive data to ensure compliance.

3. Risk Mitigation
   Minimize the impact of data breaches by reducing the exposure of sensitive information, thereby safeguarding against financial losses, reputational damage, and identity theft.

4. Secure Data Sharing
   Share anonymized datasets with researchers or other organizations without compromising privacy, fostering collaboration and innovation in fields like healthcare, finance, and social sciences.

Installation

Install the package via Composer:

composer require ramiroestrella/laravel-database-anonymize

Publish the configuration file with:

php artisan vendor:publish --provider="RamiroEstrella\LaravelDatabaseAnonymize\Providers\DatabaseAnonymizeServiceProvider"

The published configuration file (config/laravel-database-anonymize.php) includes:

return [
    'locale' => 'en_US',
    'chunk_size' => 1000,

    /*
    |--------------------------------------------------------------------------
    | Restricted Environments
    |--------------------------------------------------------------------------
    | Define environments (e.g., production, staging) that require confirmation 
    | before running anonymization commands for added security.
    */
    'restricted_env' => ['production', 'staging'],

    /*
    |--------------------------------------------------------------------------
    | Model Ordering
    |--------------------------------------------------------------------------
    | Optionally define the order of model anonymization. Priority models are
    | processed first to ensure dependencies are handled correctly.
    */
    'priority_models' => [],
];

Usage

Step 1: Implement the Anonymizable Trait

Add the Anonymizable trait to models containing sensitive data and define the anonymizableAttributes method.

Example (App\Models\User):

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Builder;
use RamiroEstrella\LaravelDatabaseAnonymize\Traits\Anonymizable;
use Faker\Generator;

class User extends Authenticatable
{
    use Anonymizable;

    public function toAnonymize(Generator $faker): array
    {
        return [
            'email' => $this->id . '@custom.dev',
            'password' => 'secret',
            'firstname' => $faker->firstName,
            'surname' => $faker->lastName,
            'phone' => $faker->e164PhoneNumber,
            'position' => $faker->jobTitle,
            'token' => null,
        ];
    }

    // Optional: Specify conditions for anonymization
    public function anonymizeCondition(): Builder
    {
        return self::withTrashed()->where('something', '>=', '...');
    }
}

Step 2: Anonymize Related Models

If your model has relationships, you can specify the data to anonymize within related models using the relations property.

Example (App\Models\Employee):

<?php

namespace App\Models;

use RamiroEstrella\LaravelDatabaseAnonymize\Traits\Anonymizable;
use Faker\Generator;

class Employee extends Authenticatable
{
    use Anonymizable;

    public function anonymizableAttributes(Generator $faker): array
    {
        $firstName = $faker->firstName();
        $lastName = $faker->lastName();

        return [
            'name' => $firstName . ' ' . $lastName,
            'relations' => [
                'person' => [
                    'first_name' => $firstName,
                    'family_name' => $lastName,
                ],
            ],
        ];
    }
}

In this example:

• The name attribute of the Employee model is anonymized.
• The related person model has its first_name and family_name attributes anonymized as well.

Step 3: Run the Anonymization Command

Anonymize all models:

php artisan db:anonymize

Anonymize specific models:

php artisan db:anonymize --model=App\\\\Models\\\\User --model=App\\\\Models\\\\Employee

Exclude a specific model:

php artisan db:anonymize --exclude=App\\\\Models\\\\Employee

Configuration Options

• Locale: Defines the locale used by Faker (default: en_US).
• Chunk Size: Processes data in chunks for memory efficiency (default: 1000).
• Restricted Environments: Prevents accidental anonymization in critical environments like production or staging.
• Priority Models: Ensures dependent models are anonymized in the correct order.
