Browser Fingerprint: What Is It and How to Not Leave One

As you surf the internet, your browser collects and transmits personal information. Without your knowledge, browsers leave behind a unique digital fingerprint. This is known as browser fingerprinting, a technique used by websites and advertisers to gather data without explicit consent. 

In the United States, around 307 million people out of 330 are connected to the Internet. Numerous studies exploring the concept of fingerprinting reveal something intriguing: around 80% to 90% of browser fingerprints are one-of-a-kind. This means that for most of these Internet users, their unique online identities are being collected without their knowledge. 

In this revealing exposé, we delve into browser fingerprinting, unveiling its inner workings and impact on your privacy. We’ll also provide battle-tested strategies to minimize its effects and protect your personal information.

Understanding Browser Fingerprinting

Browser fingerprinting is the secretive process of gathering data about a user’s browser and device, creating a unique digital profile that distinguishes them from others. It involves collecting various data points from the user’s browser and device and merging them into an unchangeable and distinctive fingerprint.

These data points include the user agent string, HTTP headers, installed fonts and plugins, screen resolution and color depth, time zone, and language settings, as well as cookie and cache usage.

By combining these fragments and analyzing their variations, websites, and third parties can create an indelible digital fingerprint, enabling them to track users across multiple websites and browsing sessions. The main goal of browser fingerprinting is to trace users and compile detailed records of their online activities. This technique raises concerns about online privacy:

  • Browser fingerprinting techniques can track you with an accuracy of over 99% across various websites. It allows websites and advertisers to track users across devices and platforms, surpassing traditional tracking methods like cookies. 
  • Browser fingerprinting compromises user privacy by collecting intricate details about browsing habits and preferences. This information can be exploited for targeted advertising, personalized content delivery, and potentially shared with data brokers.
  • Almost 60% of data breaches involved personal data, and the average cost of a data breach was estimated to be $3.86 million. The extensive profiling facilitated by browser fingerprinting exposes users to tailored advertisements and increases the risk of data breaches. The wealth of collected data makes users vulnerable to privacy violations if the information falls into the wrong hands.

Strategies to Minimize Browser Fingerprinting

In an era fraught with mounting concerns over online privacy, safeguarding oneself from the perils of browser fingerprinting has become imperative. By embracing a proactive approach and employing the following strategies, one can substantially diminish the likelihood of being tracked by external entities.

To empower privacy through browser settings, leading-edge browsers offer a multitude of options. Users can obstruct third-party cookies, and configure their browsers to intercept and repel these exploited tracking tools. By curbing or disabling JavaScript, users can limit the additional information that can be procured about their browser. Prudent management of browser extensions and plugins is also crucial to minimize the risks associated with fingerprinting.

Leveraging privacy-focused browsers and extensions enhances the safeguarding of browser privacy. Privacy-centric browsers offer native privacy features, including advanced tracker blocking and fortified fingerprinting protection. Integrating reputable browser extensions can further impede trackers, bolster secure connections, and provide greater command over online privacy.

Moreover, embracing anonymity tools is paramount for maximal privacy fortification. In the United States, the adoption of Virtual Private Network (VPN) technology witnessed a remarkable surge in recent years. VPNs hide IP addresses, encrypt internet connections, and route them through remote servers, making it arduous for third parties to trail online activities. 

Proxy servers there act as intermediaries, hiding IP addresses and curbing traceability. The Tor network, often referred to as the Onion network, routes internet traffic through an intricate web of volunteer-operated relays, bolstering the protection of digital identity.

To reinforce online privacy, you must embrace online privacy best practices. Regularly purging cookies, cache, and browsing data eliminates residual traces that can be used to track your digital persona. Using private browsing or incognito mode restricts data retention and prevents tracking across browsing sessions. Exercise caution with browser configurations or plugins that render browsers uniquely identifiable. 

Staying informed and educated about online privacy and emerging browser fingerprinting techniques enables proactive adaptation of privacy practices to evolving threats.


What is a browser fingerprint?

A browser fingerprint is a unique identifier generated by a web browser based on various characteristics and settings of the user’s device and browser. These characteristics may include the user agent, screen resolution, installed plugins, language preferences, and more. Browser fingerprints are often used for tracking and can be used to distinguish and identify individual users online.

How do I get a browser fingerprint?

There exist numerous alternative methods for acquiring a distinct browser fingerprint. Among the latest techniques is known as ‘Canvas Fingerprinting.’ In essence, websites are constructed using HTML5 code, and within this code, a small snippet is embedded that captures your browser’s unique fingerprint.


In an era where technology surges ahead at an unprecedented pace, maintaining a vigilant stance and tightening your privacy practices is of utmost importance. Embracing a proactive approach allows you to curtail the effectiveness of browser fingerprinting, fortifying the protection of your personal information.
