In this video, we build a full redaction and anonymization system using Microsoft Presidio, local LLMs, and the Faker library, ensuring that cloud models like Claude Haiku never see real names, financials, or personal information. We cover the real-world challenges of entity resolution, surrogate data generation, and reversible anonymization — and show you honestly where things break down and how we fixed them. 📌 What's covered: Why redaction and anonymization matter (GDPR, HIPAA, CCPA, PCI-DSS) - The difference between hard redaction (irreversible) and reversible anonymization with surrogate data - How Microsoft Presidio identifies PII using pattern matching, named entity recognition, and context enhancement - The entity resolution problem — why "Margaret Thompson," "Maggie Thompson," and "M. Thompson" all need the same surrogate - Using a local LLM (Qwen 3 8B) as a safety net for entity clustering and catching missed PII - Building the full architecture with Claude Code and Agent Teams (Opus 4.6) - End-to-end testing with Langfuse tracing to verify the cloud LLM never sees real data - Hard lessons learned: why our first architecture was over-engineered and how we simplified it 🔍 Tech stack: - Microsoft Presidio (open-source PII detection) - Faker library (surrogate data generation) - Qwen 3 8B (local LLM for entity resolution) - Claude Haiku via OpenRouter (cloud LLM) - Supabase (local Postgres + auth + storage) - React frontend / Python backend - Langfuse (self-hosted tracing) - Claude Code with Agent Teams Key takeaway: Entity recognition is not perfect — even the best systems miss 5%+ of sensitive entities. You need defense in depth: technical safeguards, legal safeguards, and organizational policies working together. 🔗 PRD and requirements available in the repo below 🔗 Full codebase available to AI Automators community members 📌 This is part of our Agentic RAG series where we're building a full AI agent web app grounded in private company knowledge. ⏱️ Timestamps: 00:00:00 The Explainer 00:16:43 Phase 1 Planning 00:33:10 Phase 1 Build 00:46:30 The Rebuild! 01:00:49 New Features & Demo #AI #RAG #Privacy #Redaction #Anonymization #MicrosoftPresidio #ClaudeCode #AgenticRAG #PII #GDPR
