What Is Browser Fingerprinting Tracking About You?
Do you ever feel watched online? Not as in someone spying through your camera, but as if your cellphone knew what you’re thinking or talking about at any given time.
If you’ve taken steps to protect your privacy, such as clearing cookies or using incognito mode, you might feel safer, but it doesn’t mean you truly are.
Websites can track your activity in a myriad of ways, and not all of them are known to the public. This is the case with browser fingerprinting.
This sophisticated method collects unique details about your device and your browser and, thanks to those, they can identify you, no matter how cautious you are.
If you’re worried about your online safety, understanding how browser fingerprinting works is essential.
Let’s explore it and review how you can protect yourself against this.
What is browser fingerprinting?
Browser fingerprinting is a relatively new method that some websites use to gather details about your device and your browser.
Through this information, they can create a digital “fingerprint,” and this identifier distinguishes them from millions of other users.
How does browser fingerprinting work?
Millions of websites collect denials like:
- Browser type and version,
- Operating system,
- Screen resolution,
- Installed plugins and fonts,
- Timezone settings.
These are, on the surface, harmless details to know about you.
But, when combined, they create a unique profile that’s difficult to change or hide. Even if you delete cookies, even if you switch to incognito mode: your digital fingerprint stays the same.
It also doesn’t require your consent, and it doesn’t leave traces on your device. It operates silently in the background.
What can browser fingerprinting track about you?
Your online behavior. Research indicates that 74% of desktop devices can be uniquely identified, so they’re highly trackable. For mobile users, the figure is around 45%, showing that no platform is entirely immune.
What does it reveal about you?
For marketers and advertisers, this is very valuable information, and they’ll certainly use it to create hyper-targeted ads, considering your interests.
Data brokers can also find value in browser fingerprinting, as they can compile profiles and sell them to companies and organizations.
So, browsing fingerprinting tracks:
- Browsing activities: the websites that you visit link your fingerprint to your browsing activities. It can be detailed about your online visits, even across different sessions or devices.
- Your location: the place where you live, even if it’s not exact. Combining your timezone with your IP address narrows down your location significantly.
- Your habits and preferences: what websites do you visit the most? What’s your shopping behavior like? When are you the most active?
The worst part of this is that hackers can exploit this information to try and scam you or steal your identity. In truth, it is a rising threat to those who want to keep themselves anonymous online.
Why should you care about browser fingerprinting?
You have a right to online privacy.
Even if you have nothing to hide, you must keep your information private when you want to. Remember, cloud environment intrusions increased by 75% over the past year.
If you’re concerned about privacy or cyberthreats, protecting yourself from browser fingerprinting is essential.
Steps to protect yourself from browser fingerprinting
Fortunately, there are some things you can do to avoid this anti-ethical move from companies and cybercriminals.
- Use a Privacy-Focused Browser: download a website that offers tools to minimize fingerprinting, like Firefox.
- Employ Anti-Fingerprinting Extensions: a few extensions can help block trackers, like privacy badger. Research and decide which one suits you best.
- Change Your Browser Settings: limit plugins and disable JavaScript when you don’t need it.
- Get a VPN Download App: a VPN helps you stay anonymous online, and it’s effective when you’re serious about your right to privacy.
Comparison Table: Browser Fingerprinting vs. Cookies
Cookies can store data on your device, so when you delete them, you’re not as easily tracked, but fingerprints are created by analyzing your browsing environment.
Here’s the difference between the two.
Aspect | Browser Fingerprinting | Cookies |
---|---|---|
Persistence | Hard to reset or block | Easy to clear via browser settings |
User Control | Limited | Users can block or delete |
Tracking Across Devices | Possible if the environment matches | Device-specific tracking only |
Usage | Advertising, analytics, and cyberthreats | Mainly used for website preferences |
Final thoughts
Browser fingerprinting is a sophisticated, and questionable method of gathering data. A lot of people agree on the threat this presents to online privacy, basically because it makes it nearly impossible to stay anonymous.
Staying informed about these things is the first step to being safe. Take proactive measures and reclaim control over the information people have access to.
Browser fingerprinting isn’t easy to prevent, but you can still do a lot with the right tools.
