Data Masking for AI

Redacting or replacing sensitive data such as PII before it reaches an AI model or appears in outputs.

Definition

Masking and tokenization of sensitive fields reduce privacy and compliance risk in prompts, logs and training data. Bedrock Guardrails, Amazon Comprehend, Azure AI Language PII detection and the Einstein Trust Layer provide it.

Exam tip

Mask PII before it reaches the model and before outputs are logged.
