Many internet surfers believe that deleting browser cookies and using private browsing does not disclose their online behavior. Yet, websites use complex tracking mechanisms that operate even when there is no need to store tracking files locally. This knowledge of the mechanisms of browser fingerprinting will allow us to see how companies create unique profiles in order to track people’s online activities.
Browser fingerprinting is an effective technology that collects the unique configuration data from a user’s browser and operating system. When one uses a website, the user’s browser automatically sends the information needed for rendering websites correctly.
The trackers collect these small bits of technical data like the screen resolution, fonts, browser extensions used, and others, creating a unique digital profile. The fact that this data configuration is unique allows the websites to recognize the visitors without using traditional cookies.
A website utilizes hidden code to collect subtle information about a user’s system that can create a digital footprint:
The HTML5 script asks the browser to draw a hidden graphical background. Tiny differences in the hardware and graphics processing unit result in slight deviations that create a distinctive visual hash.
By using the Web Audio APIs, websites analyze how a computer processes the sound signal to create a distinctive frequency signature.
Code collects information about system fonts, screen resolution, timezone, battery life, and operating system updates.
An analysis of browser fingerprinting reveals why many organizations use tracking scripts:
A data aggregator or advertising network creates profiles for users based on their browsing history from different domains. This way it is possible to show hyper-targeted ads without depending on third-party cookies.
Financial companies use device fingerprinting to prevent fraudulent actions. When a user tries to log in to a bank account from a new device, its fingerprint is checked, and further verification may be requested.
Understanding how browser fingerprinting works enables internet users to realize the scale of data collection. By using privacy-oriented browsers and limiting unauthorized script execution, people will be able to mask their hardware information and restore their internet privacy.
