Sensitive Data Obfuscator Extension

Overview

The Sensitive Data Obfuscator extension is a lightweight Data Loss Prevention (DLP) tool designed to protect sensitive information when interacting with Large Language Models (LLMs). It automatically detects and obfuscates confidential data—such as credit card numbers, passwords, and personal identifiers—when users copy and paste content into LLM chat interfaces.

What It Does

This Firefox extension acts as a security layer between you and AI tools, ensuring that sensitive data is protected before being sent as prompts. When you paste text containing sensitive information into LLM platforms like Claude.ai, ChatGPT, or other AI chat interfaces, the extension:
  • Automatically detects sensitive data patterns in real-time
  • Obfuscates the data with contextual tokens (e.g., [CREDIT_CARD], [PASSWORD])
  • Provides interactive management through a floating panel interface
  • Allows selective reveals where you can choose to use original values when needed

Supported Data Types

The extension detects and protects:
  • Financial Data: Credit card numbers, account numbers, transit numbers, institution numbers
  • Personal Identifiers: Social Security Numbers (SSN), SIN, phone numbers, email addresses
  • Credentials: Usernames, passwords, security codes
  • Custom Patterns: Additional sensitive data patterns

How to Use

Basic Usage
  1. Copy sensitive data to your clipboard
  2. Paste into the LLM chat interface - sensitive data is automatically obfuscated
  3. Review the prompt - sensitive information appears as tokens like [CREDIT_CARD], [USERNAME]
  4. Manage data via the floating shield button that appears

Interactive Management

When sensitive data is detected, a floating shield button appears:
  1. Click the shield to open the Sensitive Data Manager
  2. View all detected items with their current display status
  3. Use available actions:
  4. Use Original: Show the actual value in the prompt
  5. Remove: Delete the sensitive field entirely

Supported Platforms

Currently optimized for:
- Claude.ai
- ChatGPT/OpenAI
- Google Bard/Gemini
- Bing Chat
- Perplexity.ai
- You.com
