PrivacyScrubber offers two primary Zero-Trust deployment interfaces: our Web-Based Secure Workspace and our Chrome Browser Extension. Both operate with 100% client-side zero-trust execution, giving teams flexibility across high-volume document batch processing and seamless in-browser live typing protection.

Zero-Trust Architecture: Direct Web vs. In-Page DOM Injection

Both interfaces share the exact same V8 regex engine, 25 specialized industry profiles, and cryptographic Argon2id + XChaCha20-Poly1305 handoff pipeline.

● IN-PAGE SANDBOXED INTERCEPTION Intersects DOM input before network transmission. Evaluates regex in <2ms browser RAM.
● 3-LINE LOOKAHEAD STITCHING Automatically re-assembles entities split across linebreaks before tokenization.
● REVERSIBLE TOKEN MAP Substitutes raw PII with reversible tokens ([NAME_1], [ID_1]) for instant 1-click restore.
● ADMIN BLUEPRINT LOCK Enterprise policies deploy with [ENTERPRISE LOCKED] badge — tamper-proof for staff.

Choosing the Right Sanitization Interface for Your Workflow

The Web Secure Workspace excels at bulk file processing—allowing users to drag-and-drop hundreds of DOCX, PDF, CSV, and image files for batch de-identification and OCR. The Chrome Extension is engineered for zero-friction real-time protection, automatically detecting and redacting text inside ChatGPT, Claude, and Gemini inputs without requiring tab-switching.

Hybrid Enterprise Deployment Model

  1. 1
    Copy or Paste Unsanitized Content: Compliance officer processes bulk quarterly employee evaluations (50 DOCX files) via the Web App batch engine in under 3 seconds.
  2. 2
    Real-Time In-Browser Sanitization: Knowledge workers use the Chrome Extension daily for real-time in-page prompt sanitization while chatting with ChatGPT and Claude.
  3. 3
    Submit to LLM with Zero Cloud Exposure: Both tools share synchronized custom regex rules and company token taxonomy via True Sync zero-server architecture.
  4. 4
    Instant Local Reversal (Contextual Reveal): Both interfaces produce identical cryptographic CISO Audit Receipts with local SHA-256 validation.

Zero-Server Architecture Across All Deployment Planes

Regardless of interface, zero bytes of prompt text are ever transmitted to PrivacyScrubber servers. Everything runs strictly in the browser's local memory, fulfilling AI Privacy Guides zero-trust standards.

Unified Token Map & Multi-Plane Interoperability

Tokens generated in the Web App can be decoded seamlessly in the Extension and vice versa, providing seamless team handoff as documented in PII protection basics and Zero-Trust AI frameworks.

Consolidated Security Audits

Both tools support unified CISO audit logging, verifying that enterprise data never crossed the perimeter across all planes, meeting GDPR/CCPA standards standards.

Latest Capabilities: Multi-Line Stitching & Local OCR

The PrivacyScrubber Chrome Extension features a smart 3-Line Name-Stitching Lookahead to capture names split across lines (e.g. Firstname MiddleInitial Surname) in scanned medical/clinical records, NDAs, and PDFs. It also supports Local Wasm OCR & PDF Sanitization to redact text from screenshots/PDFs offline, and Zero-Trust Session Sync (Argon2id + XChaCha20-Poly1305) to share rules peer-to-peer securely.
