How does fingerprint recognition work?Tracking without cookies – zimo News


In recent years, issues of personal data and its collection have often emerged in the wake of cases such as the leaks and the Cambridge Analytica scandal. Often referred to as a primary tool for abusive data collection, third-party cookies aren’t the only way advertisers can target you. Fingerprints, while little known, are also stealthy when it comes to their tracking.

Fingerprinting is the process by which a remote site or service collects a small amount of information about a user’s device and combines it to form a unique profile or “digital fingerprint” of the user’s device.The two main forms of footprints are navigatorthis information is provided by the browser when the user visits the website, and the device fingerprint, where the information is provided by application The user has installed it on their device.

an increasingly common practice

In most cases, fingerprinting is done by a third party, not directly by the site the user is visiting or the application they are using. When a person uses their device, certain third-party trackers may be loaded in multiple installed applications or sites visited. This allows the company to track individuals through the multiple sites they visit or the use of apps they install. These trackers provide unprecedented insight into users’ daily activities, providing them with information that is often precise enough to know what users are doing at any given time, or even where they are using their devices.

It’s okay to activate private navigationyou erase biscuit third parties or you use virtual private network. Ironically, some people even take advantage of the fact that you activate data protection options in your browser to get your fingerprint.

There are many tools that try to break fingerprint persistence in browsers.Some people try to randomize the results of certain features, such as fingerprintsaudio context. This may be an efficient way to break persistence, but it is important to note that the tracker may be able to determine that a randomizer is being used, which may itself be a feature of the footprint. The effectiveness of randomization of footprint characteristics in hitting trackers needs to be carefully considered.

Tor node

Browsers can also combat fingerprinting by making all instances of the browser look the same. By making the fingerprint characteristics the same for all browser instances, a specific instance cannot be uniquely identified. This is the approach taken by the Tor anonymity tool.

It works very well for fingerprints if done correctly. Tor Browser has identified a lot of work that needs to be done to make all browsers look the same across all functions. This is important because users who change their personal settings to avoid trackers can easily actually make their browsers more recognizable by trackers.

anti-tracking tool

Finally, a tool to draw a list tracking device and block them outright.This is the approach taken by many browser plugins or extensions, such as Privacy Badger EFF. By blocking trackers, these tools are able to prevent most fingerprint trackers from loading into the browser. Most third-party trackers that use fingerprints to identify users cannot identify users’ browsers.
