Advanced Data Protection

Advanced Data Protection is ALTR’s set of techniques for protecting sensitive data at the level of an individual value. Tokenization and Format-Preserving Encryption (FPE) protect values in a connected data source, through Snowflake policy or through the API. AI Data Shield protects values in the free text an application sends to an AI service.

  • Format-Preserving Encryption – Encrypt a value while preserving its original format and length.
  • Tokenization Access Policies – Configure what a role sees when querying tokenized data.
  • AI Data Shield – Protect sensitive data in the text an application sends to an AI service, and restore it when policy allows.
