A financial institution uses Azure AI Search to index customer feedback forms. The forms are scanned PDFs and contain sensitive Personally Identifiable Information (PII) like names and account numbers. You need to ensure that this sensitive information is automatically detected and removed from the search index before it is stored. Which Azure AI Search skill should you use?
- APII Detection skill
- BLanguage Detection skill
- CKey Phrase Extraction skill
- DEntity Linking skill
Show answer & explanationAnswer & explanation
Correct answer: A. PII Detection skill
The PII Detection skill is specifically designed to identify and redact or remove sensitive information like names, account numbers, and other PII from text, which is crucial for compliance and privacy in this scenario.
Why the other options are wrong
- B. The Language Detection skill identifies the language of the text, not sensitive information.
- C. The Key Phrase Extraction skill identifies important phrases in text, not sensitive information.
- D. The Entity Linking skill resolves entities to a known knowledge base, not for PII detection.
PII Detection Skill
An Azure AI Search skill that identifies, categorizes, and optionally redacts personally identifiable information (PII) from unstructured text.
- Detects various types of PII (e.g., names, credit card numbers, phone numbers).
- Can be configured to redact or remove identified PII.
- Essential for privacy compliance and data security in search solutions.
Memory trick: PII is private, so PII Detection protects it.
