Microsoft Certified: Azure AI Engineer AssociateImplement natural language processing solutionsEasy
A call center is integrating an AI-powered assistant to help agents by transcribing customer calls in real-time. The solution must also automatically detect and redact sensitive customer information, such as credit card numbers and social security numbers, from the transcripts before storing them. Which Azure AI service feature should be used for this redaction?
- AKey Phrase Extraction
- BSentiment Analysis
- CEntity Linking
- DPersonally Identifiable Information (PII) Detection
Show answer & explanationAnswer & explanation
Correct answer: D. Personally Identifiable Information (PII) Detection
The requirement to 'detect and redact sensitive customer information, such as credit card numbers and social security numbers' directly corresponds to the functionality of Personally Identifiable Information (PII) Detection. This feature is designed to identify and optionally redact such sensitive data.
Why the other options are wrong
- A. Key Phrase Extraction identifies important concepts, not sensitive personal data.
- B. Sentiment Analysis determines emotional tone, which is irrelevant to data redaction.
- C. Entity Linking resolves entities to a known knowledge base, not for redaction of sensitive data.
PII Detection (Azure AI Language)
A feature of Azure AI Language that identifies, categorizes, and can optionally redact sensitive personal information (PII) from unstructured text, helping organizations meet privacy and compliance requirements.
- Automatically detects various types of PII (e.g., names, addresses, credit cards).
- Can replace detected PII with a placeholder (redaction).
- Crucial for data privacy and compliance.
Memory trick: PII Protects Important Information.
