BroprintJS is an open-source browser fingerprinting tool that reveals the vast amount of information websites can collect about your browser and device. When combined, this information creates a highly unique “fingerprint” that websites can use to identify and track you, even if you clear your cookies or use incognito mode.
Below, we’ll explore BroprintJS and the privacy risks it uncovers through a 10-question Q&A.
10 Questions and Answers about BroprintJS
1. What is BroprintJS?
BroprintJS is an online tool designed to detect and display your browser’s unique fingerprint. It gathers numerous data points, including hardware, software, fonts, plugins, and screen resolution, and generates a unique hash (Broprint Hash) to represent your device.
2. What is a browser fingerprint?
A browser fingerprint is a unique digital profile created by collecting various configuration details from your browser and device, such as user agent, installed fonts, screen size, operating system, and language. Because the combination of these settings is likely unique to you, this fingerprint is highly specific.
3. What is the purpose of the “Broprint Hash” in BroprintJS?
The “Broprint Hash” is a summary value generated by BroprintJS based on all the information it collects. Its main purpose is to provide a simple way to gauge how unique your fingerprint is. It is extremely rare for two different users to have the exact same hash value.
4. How do websites use the information from BroprintJS to track me?
Websites can associate your browser fingerprint with your online activities, such as browsing history and click behavior. Even if you are not logged in, a website can recognize you as a “returning visitor” through this unique fingerprint, allowing for personalized ads or behavioral analysis.
5. What is Canvas fingerprinting and how does it work?
Canvas fingerprinting is an advanced tracking technique. It works by instructing the browser to draw a hidden graphic or text on an HTML5 Canvas element. Due to subtle differences in graphics processing units (GPUs), graphics drivers, and fonts across devices, the resulting image data will vary. By calculating a hash of this image data, websites can obtain a highly unique identifier.
6. Can my installed fonts be used to identify me?
Yes. The list of fonts installed on a person’s computer is often a unique combination. BroprintJS lists all the fonts accessible by your browser, and this list is a significant component of your unique fingerprint.
7. What role does WebGL information play?
WebGL (Web Graphics Library) enables hardware-accelerated 3D rendering in browsers. BroprintJS collects information about your graphics card model (Renderer) and vendor (Vendor). These hardware-level details significantly increase the uniqueness of your fingerprint, making you easier to identify.
8. Is it safe to use BroprintJS?
Yes, using BroprintJS is safe. It does not steal your data; it acts as a “mirror,” showing you the information that any potentially malicious website could see about you. It’s an excellent educational tool for understanding your digital footprint.
9. How important are the timezone and language information detected by BroprintJS?
Timezone and language settings add geographical and cultural context to your fingerprint. While not unique on their own, when combined with other data points (like IP address and WebRTC leaks), they can help websites pinpoint and analyze users more accurately.
10. How can I prevent websites from obtaining my browser fingerprint?
Conventional privacy tools like VPNs or incognito mode are not very effective against fingerprint tracking. A VPN can hide your IP but cannot alter the other components of your browser fingerprint. To truly prevent tracking, you need a tool that can actively modify or spoof these fingerprint characteristics.
Protect Your Digital Identity with FlashID
As BroprintJS demonstrates, your browser unknowingly leaks a vast amount of personal information that can be used for tracking. For users who need to manage multiple online accounts (for e-commerce, social media, digital marketing, etc.), this tracking can lead to account linkage and subsequent bans.
This is where a professional fingerprint browser like FlashID comes in.
FlashID is a powerful anti-detect browser that solves environment detection issues by creating multiple, isolated virtual browser environments. In each environment, FlashID generates a completely new, authentic fingerprint that is entirely different from your real device.
- Isolated Environments: Each browser profile has its own cookies, cache, IP address, and fingerprint information, preventing any correlation between accounts.
- Fingerprint Spoofing: FlashID intelligently modifies hundreds of fingerprint parameters, including Canvas, WebGL, fonts, and audio context, making you appear as a normal, independent new user to every website.
- Team Collaboration: Supports sharing and management of browser profiles among team members, boosting productivity.
If you want to escape the tracking risks revealed by BroprintJS, effectively manage your online business, and protect your digital identity from being easily identified, FlashID is your ideal choice.
