About Shield: AI Privacy for ChatGPT & Claude

๐Ÿ›ก๏ธ INFINIUM SHIELD โ€” AI PRIVACY FIREWALL Every message you send to ChatGPT, Claude, or Gemini passes through their servers โ€” and stays there. Shield intercepts your prompts before they leave your browser, replaces sensitive data with safe tokens, and swaps them back in the AI's response. You get the same answer. The AI never sees your real data. Works automatically. Zero configuration. No account required. โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ WHAT SHIELD PROTECTS โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ Shield automatically detects and masks 19 categories of sensitive data: ๐Ÿ”ด CRITICAL โ€ข API keys โ€” AWS, OpenAI, Anthropic, GitHub, Slack and generic api:/token:/bearer: patterns โ€ข Passwords โ€” all common password field formats โ€ข Database connection strings โ€” PostgreSQL, MySQL, MongoDB, Redis and more โ€ข JWT tokens โ€ข Private keys โ€” RSA, EC, OpenSSH, PGP โ€ข Secret environment variables ๐ŸŸก WARNING โ€ข Email addresses โ€ข Phone numbers โ€ข Credit card numbers โ€ข Private IP addresses (RFC 1918) โ€ข Social Security Numbers (SSN) ๐ŸŸข INFO โ€ข URLs containing embedded credentials โ€ข Internal hostnames (*.internal, *.corp, *.local) โ€ข System file paths โ€ข Personal names โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ HOW IT WORKS โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ 1. You type a message in ChatGPT, Claude, or Gemini 2. You press Enter or click Send 3. Shield intercepts the prompt in milliseconds 4. Sensitive values are replaced with tokens: [EMAIL_1], [API_KEY_1], [PASSWORD_1] 5. The clean prompt is sent to the AI 6. When the AI responds, tokens are swapped back to real values 7. You read natural, accurate text โ€” your data was never exposed The entire process is invisible. You work exactly as you normally would. โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ PRIVACY GUARANTEE โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ Shield is built on a single principle: your data never leaves your device without your knowledge.

Shield ensures personal data is masked before transmission, enforcing data minimisation by architecture, not policy. GDPR โ€” Masks personal data before it reaches third-party AI processors. HIPAA โ€” Reduces PHI exposure for healthcare organisations using AI tools. SOC 2 โ€” Provides a measurable technical control for AI data confidentiality risks. ISO 27001 โ€” Auditable control for the emerging AI tool risk category. Note: Shield is a technical control, not a compliance certification. Always consult your legal and compliance teams. โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ SUPPORTED AI PLATFORMS โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ โœ… ChatGPT (chatgpt.com + chat.openai.com) โœ… Claude (claude.ai) โœ… Gemini (gemini.google.com) โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ FREE vs PRO โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ FREE โ€” Forever, no account needed โœ“ All 19 built-in detection rules โœ“ Automatic interception on ChatGPT, Claude & Gemini โœ“ Token swap in AI responses โœ“ Popup showing what was masked โœ“ Per-site and global on/off toggle โœ“ 100% local โ€” nothing sent anywhere PRO โ€” $8/month via infinium.tools โœ“ Everything in Free โœ“ Custom rules โ€” protect project names, client names, internal codenames โœ“ Sync custom rules across all your browsers and devices โœ“ Advanced detection โ€” .env files, cloud credentials, Stripe keys, code secrets โœ“ Full audit log โ€” what was masked, when, on which AI tool โœ“ Priority support โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ A REAL EXAMPLE โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ Without Shield, pasting this into ChatGPT: "DB: postgres://admin:S3cr3tPass@db.internal:5432/prod Token: eyJhbGciOiJIUzI1NiJ9.eyJ1c2VyIjoiam9obn0.abc123 Contact: john.smith@acme-corp.com" ...sends your database password, JWT token and email directly to OpenAI's servers.
