Format-Preserving Tokenization

Databunker Pro features two tokenization engines. The previous version supported only PII/PHI/KYC tokenization, while the latest version includes a new format-preserving tokenization engine.

For instance, Databunker Pro can now tokenize credit card numbers. Unlike other solutions on the market, Databunker Pro was built with the latest data privacy requirements in mind, such as data minimization.

The product was built to handle millions of data tokenization requests, and the Databunker Pro API has been extended to support bulk tokenization requests.

What Problems Does It Solve?

  1. Data Privacy & Compliance
  • ✅ Meets GDPR data minimization requirements
  • ✅ Protects sensitive data while maintaining format
  • ✅ Ensures regulatory compliance without sacrificing functionality
  • ✅ Reduces scope of PCI DSS compliance
  1. Enterprise Scalability
  • ✅ Handles millions of records through data partitioning
  • ✅ Provides high-performance tokenization operations
  • ✅ Supports multiple data formats and types
  • ✅ Enables efficient data processing at scale
  1. Format Compatibility
  • ✅ Preserves data format for legacy system compatibility
  • ✅ Maintains data validation rules (e.g., Luhn algorithm for credit cards)
  • ✅ Enables analytics while protecting actual data
  • ✅ Supports seamless integration with existing workflows

🔄 Supported Data Types

Data Type Format Preservation Token Format
Credit Card Numbers ✅ (with Luhn check) Format-preserving + UUID
Uint64/Uint32 integers ✅ Format-preserving + UUID
Unix timestamp records ✅ Format-preserving + UUID
Text strings ❌ UUID only

🛠️ Key Features

Databunker Pro has a number of unique features:

Unique Record Support

This unique flag is used for data deduplication. It ensures that each record is saved only once, and the same token value is returned for identical records. If the original record has an expiration flag set, its expiration countdown will be reset from the beginning.

// Same input generates same token when enabled
{
    "record": "4532015112830366",
    "unique": true
}

Automatic Expiration

In Databunker Pro, expiration allows you to set a lifespan for sensitive data tokens, ensuring they automatically expire after a defined period.

// Set expiration for tokenized records
{
    "record": "4532015112830366",
    "expiration": "30d"  // 30 days
}

Dual Token Generation

By default, Databunker Pro generates two tokens: one in UUID format and another in a format-preserving manner.

// Example response for credit card tokenization
{
  "status": "ok",
  "tokenuuid": "550e8400-e29b-41d4-a716-446655440000",
  "tokenbase": "4532015112830366"  // Format-preserving token
}

🚀 Getting Started

# Example API call for tokenization
curl -X POST https://databunker.pro/api/v1/tokenize \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{
    "record": "4532015112830366",
    "type": "creditcard",
    "expiration": "30d"
    "unique": true,
  }'

Output:

{
  "status": "ok",
  "tokenuuid": "550e8400-e29b-41d4-a716-446655440000",
  "tokenbase": "4532015112830366"  // Format-preserving token
}
