FILE VAULT
Enterprise-grade document management system that automatically detects and redacts PII from PDF files using Google Cloud AI, ensuring zero persistence of sensitive data across storage and database layers. Built with defense-in-depth security architecture and comprehensive audit logging.
Project Overview
Security Architecture: Built with defense-in-depth security featuring 5-layer authorization, 7-layer data protection, and a 5-zone trust model ensuring comprehensive PII protection at every system boundary.
AI Integration: Leverages Google Cloud Document AI for OCR with bounding box coordinates, Cloud DLP for PII detection across 15+ types, and Vertex AI (Gemini 2.5 Pro) for intelligent field extraction from redacted documents.
Production Ready: Serverless architecture on Cloud Run with auto-scaling, sub-500ms API response times, comprehensive audit logging via Cloud Logging, and pay-per-use pricing optimized for cost efficiency.
