PII Tokenization Basics

Replace PII with tokens

Tokenizing PII replaces values with format-preserving tokens; the vault stores mappings with strict access, helping reduce exposure while allowing necessary workflows that require re-identification.

Design

Choose token types (format-preserving or random); define scope.

Secure Vault

Store mappings in restricted vault with auditing.

Integrate

Replace PII at ingress; detokenize only when needed.
