tools-only PII Analysis Workflow Feature
Fixed/Implemented in version: 0.229.072
Overview and Purpose
The PII Analysis Workflow feature enables users to scan documents for personally identifiable information (PII) and sensitive data patterns using AI-powered analysis. This feature integrates with the existing workflow system to provide comprehensive privacy compliance tools.
Version Information
Version implemented: 0.230.001
Technical Specifications
Architecture Overview
The PII Analysis feature is built on top of the existing workflow infrastructure and consists of:
Admin Configuration System
- Configurable PII scan patterns with severity levels
- Pattern type definitions (SSN, Email, Phone, Credit Card, Address, Custom)
- Enable/disable toggle for the entire feature
Workflow Integration
- New workflow analysis type:
pii_analysis - Integration with existing 3-step workflow process
- Dedicated API endpoint for PII analysis generation
- New workflow analysis type:
AI-Powered Analysis Engine
- Uses configured GPT models for PII detection
- Specialized prompts for privacy analysis
- Configurable severity-based risk assessment
API Endpoints
PII Analysis Generation
POST /api/workflow/generate-pii-analysis
Request Body:
{
"file_id": "document_uuid",
"scope": "workspace|group|public"
}
Response:
{
"success": true,
"pii_analysis": "Generated analysis content",
"file_id": "document_uuid",
"scope": "workspace",
"analysis_type": "pii_analysis"
}
Configuration Options
Admin Settings
- Enable PII Analysis: Master toggle for the feature
- PII Analysis Patterns: Configurable list of scan patterns
Pattern Configuration
Each pattern includes:
- Pattern Type: Predefined types (SSN, Email, Phone, etc.) or Custom
- Description: Human-readable description of the pattern
- Severity: Risk level (Low, Medium, High)

Usage Instructions
Admin Configuration
- Navigate to Admin Settings → Safety tab
- Enable "PII Analysis" toggle
- Configure PII scan patterns:
- Add/remove pattern types
- Set descriptions and severity levels
- Save settings
User Workflow
- Start workflow from main navigation
- Select document scope (Personal/Group/Public)
- Choose document for analysis
- Select "PII Analysis" option
- View generated analysis with:
- Executive summary
- Detailed findings by pattern type
- Risk assessment
- Compliance recommendations
Analysis Output Structure
The PII analysis provides:
Executive Summary
- High-level overview of findings
- Overall privacy risk assessment
PII Detection Results
- Results for each configured pattern type
- Instance counts and risk levels
- Redacted examples for security
Risk Assessment
- Overall risk score (High/Medium/Low)
- Compliance concerns (GDPR, HIPAA, etc.)
- Data sensitivity classification
Recommendations
- Immediate actions for high-risk findings
- Data handling best practices
- Compliance steps and documentation
Testing and Validation
Test Coverage
- ✅ Admin settings form processing
- ✅ Admin template JavaScript functionality
- ✅ Workflow API endpoint implementation
- ✅ Template integration and display
- ✅ Configuration version management
- ✅ Data structure validation
Performance Considerations
- Content truncation at 60,000 characters to manage token limits
- Higher token allocation (3,000) for comprehensive analysis
- Hybrid search optimization for document content retrieval
Known Limitations
- Requires Enhanced Citations to be enabled
- Depends on configured GPT models for AI analysis
- Content truncation may affect analysis of very large documents
- PII detection accuracy depends on AI model capabilities
Integration Points
Workflow System
- Extends existing workflow with new analysis type
- Maintains consistent 3-step user experience
- Reuses document loading and PDF viewing infrastructure
Admin Settings
- Follows established pattern management approach
- Consistent with Document Classification configuration
- Uses same toggle and table management patterns
Enhanced Citations
- Leverages document storage and retrieval system
- Uses hybrid search for content analysis
- Maintains scope-based access controls (personal/group/public)
Security Considerations
Privacy Protection
- AI prompts specifically instruct to redact actual PII values
- Analysis focuses on patterns rather than exposing sensitive data
- Configurable severity levels for risk-appropriate handling
Access Control
- Respects existing document access permissions
- Scope-based analysis (personal/group/public)
- Admin-only configuration of PII patterns
Compliance Features
- GDPR and HIPAA awareness in analysis output
- Documentation recommendations for audit trails
- Risk-based categorization for compliance workflows
Future Enhancements
Potential Improvements
- Custom regex pattern support for advanced users
- Export capabilities for compliance reporting
- Integration with external compliance tools
- Batch processing for multiple documents
- Historical PII analysis tracking and trends
Extensibility
- Pattern plugin system for industry-specific PII types
- Integration with data loss prevention (DLP) systems
- Automated remediation suggestions
- Real-time PII monitoring for document uploads
Maintenance
Configuration Updates
- PII patterns can be modified without code changes
- New pattern types easily added through admin interface
- Severity levels adjustable based on organizational policies
Monitoring
- API endpoint logs for analysis requests
- Error handling for failed analysis attempts
- Performance tracking for large document processing
Troubleshooting
- Validates PII pattern configuration on form submission
- Provides clear error messages for configuration issues
- Fallback handling for missing or invalid patterns
