Who Am I App Review: Understanding Your Digital Footprint

In an era where our digital lives are increasingly intertwined with our physical existence, understanding what information we expose online has never been more important. The "Who Am I" app offers a revealing glimpse into your digital identity, showing exactly what websites can learn about you the moment you visit them.

Digital Privacy in the Modern Age

Every time you visit a website, you leave behind a trail of digital breadcrumbs. Your browser, device, operating system, screen resolution, language preferences, and even your approximate location are all readily available to websites through standard web technologies. Most users remain unaware of just how much information they're sharing simply by browsing the web.

The "Who Am I" app was developed to address this knowledge gap, providing users with a comprehensive overview of their digital fingerprint in a clear, accessible format.

How "Who Am I" Works

Upon launching the app, "Who Am I" immediately begins analyzing various aspects of your digital presence:

• Browser Fingerprinting: The app examines your browser's unique characteristics, including version, plugins, and settings.
• Device Information: Details about your hardware, operating system, and screen specifications are collected and displayed.
• Network Analysis: Your IP address is used to determine your approximate location, internet service provider, and connection type.
• Cookie Audit: The app scans for existing cookies and local storage data that might be tracking your online activities.
• Canvas Fingerprinting Detection: Advanced tracking techniques that use HTML5 Canvas elements are identified and explained.
• WebRTC Leak Testing: The app checks if your real IP address is exposed through WebRTC connections, even when using a VPN.

All of this information is presented in a user-friendly dashboard that categorizes data points by sensitivity and potential privacy implications.
