Summary

An interactive article demonstrating how browser fingerprinting, hardware signatures, and cross-device tracking create identity anchors that blockchain analytics exploit. The article collects real data from the reader’s browser and weaves it into the narrative — personalizing the text with the reader’s actual fingerprint, GPU, timezone, screen resolution, etc. Includes interactive demos: fingerprint reveal, hardware signature (cross-browser), network signature (cross-device), QR-based cross-device linking, identity graph visualization, and zombie cookie resurrection.

Positioned as a “Stage 0” prequel to the published Anatomy of Exposure article — establishing that privacy is lost before the user ever touches a blockchain.

Audience

Primary: Privacy-conscious crypto users, blockchain developers, security researchers Secondary: General tech audience interested in surveillance/fingerprinting, journalists covering privacy

Key Angles

  • Browser fingerprinting achieves ~1 in 8 billion uniqueness without cookies
  • Hardware signatures (GPU, cores, screen, audio) persist across browsers — 99.24% cross-browser identification (Cao et al. 2017)
  • Network signatures link all devices on the same WiFi with ~90% accuracy
  • Zombie cookies resurrect from localStorage/IndexedDB after cookie clearing
  • Identity graphs (LiveRamp: 200M+ people, 600M+ devices) feed chain analytics
  • Full-stack privacy requires infrastructure change, not just transaction-level crypto
  • Logos positioned as the systemic solution: Messaging, Storage, Blockchain

Interactive Elements

  • Fingerprint Reveal — computes and displays reader’s canvas fingerprint
  • Hardware Signature Panel — shows cross-browser stable signals (GPU, cores, screen, audio)
  • Network Signature Panel — shows cross-device linking signals (timezone, language, region)
  • Cross-Device QR Demo — scan with phone to see yourself get linked
  • Identity Graph Visualization — step-through animation showing signal convergence
  • Zombie Tracker Demo — plant/clear/resurrect a tracking cookie
  • Full Exposure Panel — reveals all 20+ collected data points

Technical Notes

  • Standalone HTML with React 18, Tailwind CSS, Babel (browser-side JSX)
  • Jinho has validated interactivity works within the Logos Press Engine
  • No server-side data collection — all fingerprinting runs client-side for demonstration
  • QR code generation via qrcode.js library

Review Status

  • Draft complete (standalone HTML)
  • Press Engine integration validated (Jinho)
  • Author review (Corey — in progress)
  • Stakeholder review
