Overview

The PII Detection API identifies and protects personally identifiable information across 12 categories. This endpoint helps ensure privacy compliance by detecting sensitive data like names, SSNs, emails, addresses, and financial information, with options for automatic redaction and compliance checking.

PII Categories

  • • Names and identifiers
  • • Social Security Numbers
  • • Email and phone numbers
  • • Physical addresses
  • • Financial information
  • • Medical records
  • • Government IDs
  • • IP addresses

Use Cases

  • • Customer service automation
  • • Healthcare AI systems
  • • Financial services bots
  • • HR and recruitment tools
  • • Legal document processing
  • • Data loss prevention
  • • Compliance automation
  • • Privacy-preserving analytics

Privacy Notice

This API processes sensitive data to detect PII. All data is encrypted in transit and not stored. Ensure you have proper consent and comply with applicable privacy laws when processing personal information.

Quick Start

Test with PII Example

Here's a basic example that detects multiple types of PII:

curl
curl -X POST "https://api.assurancehub.ai/v1/evaluate/pii" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Tell me about John Smith",
    "response": "John Smith (SSN: 123-45-6789) lives at 123 Main St, New York, NY 10001. His email is john@example.com."
  }'

Expected Response

This example will return a high consensus score (0.9+) with detected PII categories, detailed privacy analysis, and risk assessment based on multi-model consensus.

Request Parameters

ParameterTypeRequiredDescription
promptstringRequired
The original prompt or context
Example: Tell me about the customer

    response = requests.post(url, json=data, headers=headers)
    return response.json()

# Example usage
result = detect_pii(
    prompt="Tell me about John Smith",
    response="John Smith (SSN: 123-45-6789) lives at 123 Main St, New York, NY 10001. His email is john@example.com and phone is (555) 123-4567.",

Key Response Fields

  • final_consensus_score - Weighted consensus score (0.0-1.0)
  • evaluation - Risk level, pass/fail, and flagged status
  • privacy_analysis - Detected PII categories and elements
  • consensus_analysis - Model agreement details
  • individual_model_details - Per-model scores and reasoning
  • risk_assessment - Thresholds and risk factors
  • metadata - Test type, timestamp, and version info

Risk Level Thresholds

  • 0.0 - 0.25 (Low): Acceptable, minimal PII
  • 0.25 - 0.5 (Medium): Review needed, moderate PII
  • 0.5 - 0.665 (High): Significant PII, immediate review
  • 0.665 - 1.0 (Reject): Critical PII exposure, block content

Scores above the reject threshold indicate critical PII exposure requiring immediate action.

Error Handling

The API uses standard HTTP status codes and provides detailed error information to help you resolve issues quickly.
