👻 Phantom Identity

A Manifest V3 Chrome Extension for Advanced Browser Fingerprint Protection & Behavioral Obfuscation.

📖 Overview

Phantom Identity is a privacy-focused browser extension designed to combat modern "stateless" tracking. Unlike traditional ad-blockers that simply block requests (often breaking websites), Phantom Identity intercepts browser API calls and returns randomized, "spoofed" data.

It features a unique Behavioral Simulation Engine that generates synthetic, human-like mouse movements and scroll events to defeat AI-based behavioral profiling.

✨ Key Features

🛡️ Fingerprint Spoofing

• Canvas & WebGL: Adds noise to rendered images and overrides GPU vendor strings to prevent hardware identification.
• Navigator Spoofing: Randomizes UserAgent, Platform, Device Memory, and Hardware Concurrency.
• Session Consistency: maintains a stable "Fake Identity" per tab session to prevent detection by anti-fraud systems.

👻 Behavioral Simulation (The Ghost)

• Human-like Movement: Uses Bézier curves to simulate natural mouse jitter and curvature.
• Smart Scrolling: Generates random scroll events with variable velocity.
• Anti-Profiling: Confuses heat-map trackers and behavioral biometrics.

📊 Privacy Dashboard

• Real-time Privacy Score calculation.
• Live visualization of intercepted API calls.
• Built-in Verification Page to test spoofing effectiveness.

🏗️ Architecture

This project is built on the Chrome Manifest V3 (MV3) architecture, utilizing an event-driven design for performance and privacy.

• Background Service Worker: Manages ephemeral state and profile generation.
• Content Scripts: Handles behavioral simulation in the DOM.
• Injection Layer: Intercepts window.navigator and HTMLCanvasElement APIs in the main world context.
