Features & Roadmap

Features

Tabular Anonymisation

  • Diverse transformation techniques: Generalisation, masking, hashing, encryption, pseudonymisation, suppression, and more
  • K-anonymity testing: Test against IM8 WOG Access Modes A and B with privacy risk scoring
  • Utility analysis: Assess information loss before committing to transformations
  • Templates: Save, reuse, and share anonymisation configurations across your team for repeatable jobs
  • Data tagging: Tag columns as direct identifiers, indirect identifiers, or sensitive attributes with guided sensitivity classification

Free text Anonymisation

  • Auto-detection of 20+ entity types including names, NRICs, phone numbers, addresses, emails, dates of birth, bank accounts, and more
  • Multiple input formats : Supports CSV, PDF, and DOCX files
  • Custom entities: Define your own detection rules using inclusion lists, regex patterns, or privately-hosted LLMs for domain-specific terms
  • Confidence tuning: Adjust detection sensitivity per entity type to balance recall and precision for your dataset
  • Flexible anonymisation techniques: Redact, Replace with unique consistent tokens, Alias, Encrypt, Pseudonymise and more

Mock Data Generation

Generate mock data that mimics the structure and format of real datasets.

  • Singapore-specific fields: Names, NRICs, addresses, phone numbers, and other locally relevant formats
  • Custom fields: Define your own data categories for domain-specific generation
  • Field categories: Person, location, business, healthcare, and custom

Encryption and Secret/ Salt Management

Enable multi-party collaboration without exposing raw data.

  • Secrets Manager: Create, store, share, and audit encryption keys and salts in a secure, centralised location
  • Consistent encryption across datasets: Multiple data owners anonymise independently using a shared secret, producing data that can be linked on a common encrypted identifier
  • Decryption: Authorised users with access to the secret can decrypt data when needed through the Web UI or API
  • Audit trail: Full visibility of who used which secret and when

Tabular Anonymisation modules offered by Cloak

The comprehensive suite of Tabular Anonymisation Modules offered by Cloak

API Integration

The same anonymisation capabilities available through the Web UI, designed for system-to-system integration.

  • Three security levels: L2 (personalised token for integrated platforms), L3 (system token for GCC), L4 (signature-based for internet)
  • Batch processing: Handle large volumes programmatically
  • Advanced parameters: Custom recognisers, fine-grained confidence tuning, and allow lists via code

Roadmap

  • Improve performance of free-text anonymisation through novel LLM-based approaches
  • Extend modalities of access to serve a wider range of users, including non-government
  • Incorporation of other privacy technologies, e.g., Homomorphic Encryption and Searchable Symmetric Encryption to process and search data even when encrypted
