What is device fingerprinting and how does it work?

Cookies seem to be the most widely used method of identifying and tracking individuals online. However, this is not the only instance. Device fingerprinting has remained mostly unnoticed as a far more stealthy alternative to cookies. However, browser manufacturers such as Google, Apple, and Mozilla have denounced fingerprinting as an invasive privacy practice that they want to eradicate as part of a larger digital crackdown.

What is device fingerprinting and why is it necessary?

The term “device fingerprinting” is also used to refer to browser fingerprinting.

When users use the service, they need two pieces of equipment: an online connection capable of recovering an IP address and a device equipped with a mobile app or web browser. Two data sources were developed. They are accessible throughout the login, sign-up, and check-out processes, as well as when browsing the web. With the appropriate tactics, we may get significant information from both of these kinds of data.

  • Fingerprinting is the process of combining data about a device with that of a browser. It shows the user’s interaction with your service. It enables us to decipher the user’s behavior and, more importantly, to identify possible fraudsters.
  • Device Fingerprinting is the process of collecting data from a distant computer system to identify it. Additionally, when cookies are deactivated, fingerprints may be used entirely or partly to identify distinct users or machines.
  • This means that when you use your computer or smartphone to browse the internet, your device sends a large amount of specialized data to the server. Device fingerprinting is a handy technique that websites use to collect information about your operating system, browser type and version, active plugins, language, time zone, and screen resolution, among other things.
  • Such data points may seem normal at first glance and may not appear to be tailored for classifying a certain individual. However, there is an extremely small chance that the other user’s browser data will be completely matched.

What data is collected to create a device fingerprint?

Apart from the cookies, each time a web request is received at the server, device fingerprinting gives a wealth of information. It generates fingerprints based on a combination of several data pieces.

  • HTTP request headers
  • IP address
  • User-agent string
  • Client time zone
  • Installed plugins
  • Timestamps
  • Silverlight Data
  • List of the installed fonts

How does fingerprinting on devices work?

Device Fingerprinting is not very mysterious or difficult. Just as investigators gather fingerprints at crime sites, the same is true for users. Without being too analytical about the whole process, every time you visit a page, it leaves some traces on your device. These indications are collected and used to develop a user profile.

This is advantageous in a variety of situations, including when several devices are connected to the same IP address and when you need to determine which sort of web page to load for a given device.

Businesses may monitor visitors to their website and utilize the data to enhance advertising, marketing, website development, and security.

Certain internet businesses are already using device fingerprinting without your knowledge. Among them is Google Analytics. Google Analytics may be used on a mobile device, computer, or tablet to gather data on the various visitors that visit your site. However, you cannot learn about the devices used by these people; all you have is a generic list of users. You have no way of knowing who is accessing your website.

What is the purpose of device fingerprinting?

  • Devices’ Instruments Marketers may use fingerprinting to track a visitor’s activities on various websites. This often enables banks to determine if a request is being made through a confidential tool or software previously associated with fraudulent activity.
  • It enables websites to avoid having to generate multiple accounts. Through device fingerprinting, search engines may also track questionable device activity.
  • Additionally, they can identify and prevent credit card fraud or identity theft. However, these technologies jeopardize users’ privacy, and data analysis is impossible to detect.

How can device fingerprinting be prevented?

Fingerprinting is distinct from other forms of internet surveillance. You cannot circumvent it by deleting cache and cookies. No amount of browser customization can stop it. There are many possible approaches to this issue.

  1. Make use of a browser that prioritizes privacy

All browsers and devices are incapable of detecting the uncertainty range in fingerprinting. According to the author of fingerprinting software, it is feasible to protect oneself from fingerprinting by using other software. You may do this by using the Tor browser. It protects users’ privacy and makes a concerted effort to make all users’ devices seem identical.

  1. Software that is user-friendly

Safari is the browser used by Macs, Apple iPhones, and iPads, and it is notoriously tough to fingerprint. As Apple’s goods are adequately standardized, they resemble fingerprinting software. Apple’s Safari browser already minimizes traces by sending just the bare minimum of data.

While delivering information about your Device, Safari will ask for your permission and will disclose your data only if you agree. You do not need to adjust your Device’s settings since they are already activated for your safety.

  1. Make use of privacy-preserving browser extensions

Google’s Chrome browser does nothing to prevent fingerprinting. There are various browser extensions available to prevent fingerprinting, including Privacy Badger, Jackson’s Disconnect, uBlock Origin, and the Electronic Frontier Foundation’s.

  1. Deactivate Flash Player and JavaScript

Disabling device fingerprinting software that runs on Flash or Java would be the greatest defense against tracking. However, deactivating such applications may impair your internet surfing experience, since numerous websites need JavaScript to function. All of the elements that contribute to the enhancement of your online experience will be gone.

  1. Establish a VPN connection

Start utilizing a VPN service to improve your online experience and protect yourself from internet monitoring. Device fingerprinting may be prevented by connecting to a virtual private network since it totally conceals your IP address, which is not included in your “fingerprint.”

Connect with the most reputable and secure VPN provider for enhanced safety. If you are unfamiliar with VPN services and are looking for the finest VPN service, download and connect to NordVPN. It protects your data by encrypting it.

If privacy is a priority and you cannot afford to compromise on online security, NordVPN is the ideal solution since military-grade protection safeguards your device and the fast servers give you high-speed internet. It unblocks websites and enables you to visit any website you choose in a matter of minutes.
