About Browser fingerprinting

What is browser fingerprinting?

Browser fingerprinting is a powerful monitoring tool that collects parameters about browser version and type, operating system, language, time zone, screen resolution, browser plug-ins, and more. Websites rely on these parameters to identify users and track their specific behavior.canvas fingerprinting

Classification of browser fingerprinting

1) Equipment related information

The fingerprint associated with the device is mainly the exposure of some hardware condition. Your online actions are combined with device information to accurately judge your information. The equipment information mainly includes:

Hardware type, OPERATING system, user agent, system font, language, screen resolution, and Canvas fingerprint, AudioContext fingerprint, WebGL fingerprint, media device fingerprint, GPU plug-in, Pepper 3D rendering, etc.

2) Browser-related information

Including Cookie, Session, Evercookie, Flash Cookies, Browser extensions, Browser Settings (do-not-track, etc.), time zone Offset (Browser GMT Offset), Browser plug-in (Flash), and much other information.

 

Canvas fingerprinting technology

What is Canvas fingerprinting?

With the development of the Internet, users have higher requirements for the vision and interaction of pages, and traditional Web front-end development cannot be satisfied. Therefore, the powerful drawing ability of Canvas can make the content displayed on web pages more colorful, and Canvas can bring users a better visual and interactive experience.

Generally speaking, each browser uses a different image processing engine, different export options, and different compression levels, so each computer will produce slightly different graphics that can be used to assign specific numbers to the user’s device, meaning that they can be used to identify different users. This is Canvas fingerprinting.

How does Canvas Fingerprinting track your information?

Canvas fingerprinting begins when a Web site provides the browser with the task of drawing a canvas object. Canvas objects are tools that websites use to create simple and complex graphics.

The site uses Javascript to enable browsers to draw images in canvas objects using predefined scripts. This image can contain complex elements such as lines, colors, geometric shapes, with different backgrounds, or distorted in different ways.

What you need to know is that different computers will draw the image in slightly different ways. Even if the resulting image looks the same as the human eye, with slight variations, they can be distinguished.

It’s worth mentioning hash functions at this point.

A Hash algorithm, also known as a Hash algorithm, converts a piece of data into a flag that has a very tight relationship to each byte of the source data.

A remarkable feature of Hash algorithms is the difficulty of finding reverse patterns. It is a generalized algorithm, which can also be regarded as an idea. The Hash algorithm can improve the utilization of storage space, improve the query efficiency of data, and ensure the security of data transmission by digital signature. Therefore, the Hash algorithm is widely used in Internet applications.

One reason Hash algorithms are used for canvas fingerprints is that they always produce the same result if the input remains constant. Two pieces of information that look exactly the same to the naked eye can be completely different if they change slightly. Even the tiniest, tiniest differences can make a big difference.

What is Canvas fingerprinting used for?

Personalized advertising may not sound like a terrible thing, but it is not. Browser fingerprinting is often a threat to online privacy. Canvas fingerprints are also an accomplice.

Almost every website that implements browser fingerprinting does so without asking users’ consent, or in a very misleading way.

You may not remember a site that asked for permission to track your information. There is any notice, usually hidden in the site’s terms of service, in the smallest font you can imagine. Usually, it goes something like this: “By using our website, you agree that we will save your machine’s digital signature.”

Don’t worry, most users have no idea what this means any more than you do. Because it doesn’t offer any real explanation of what might happen, few people manage to see it.canvas fingerprints expose your information

Canvas fingerprint leaks can expose you to a lot of information, and then you can be hacked or harassed by targeted ads on a regular basis, as well as some not-so-obvious downsides.

How to hide your Canvas fingerprint?

Canvas fingerprint is a new intrusion technology. Before Canvas fingerprint, cookies and cache are a big hidden danger to the security of personal privacy information. But as time went by, many computer literate users tried to prevent the intrusion by deleting files on their local computers where cookies had been found to reside.

Compared to this amount of work, avoiding canvas fingerprints may require more time and effort. Here are a few possible solutions.

1) Close ads

Will closing ads solve the canvas fingerprint problem?

Of course not. But it doesn’t really cost you anything, does it?

You know, when your computer pops up some targeted AD, and you do something to let the web detect that you’re interested in it, then it keeps popping up. If you choose to turn off those ads and deny access to any of them, you’re shutting off a channel for the Internet to spy on your mind.

While this isn’t a complete solution to the Canvas fingerprint problem, it’s safer than not doing it at all.

2) Use stealth mode

As you probably know, using incognito mode prevents some cookies from being generated. Does it also work with canvas fingerprints?

This only works if some browsers have incognito modes that block website tracking. Normal browsers can only block caching and cookies, but canvas fingerprints are useless.

Browsers that can defend against canvas fingerprints use proxy networks to encrypt data. When you send a browsing request to the agent, the agent acts as a middleman to submit the request to the site for you. The website sees the proxy network. Just like when we go to an agent to buy something, the buyer and the seller don’t meet directly.

The website doesn’t know who made the request, so it can’t do anything with your Canvas fingerprint.

3) Use plug-ins

As canvas fingerprints become more and more of a concern for users, some browser-compatible plugins are coming out.

Do you know Canvas Defender? It chooses to use interference to influence the website’s judgment of canvas fingerprint. There are plenty of canvas Defender plugins out there, check them out in stores!

Check the reviews to see if they work before you download them.

4) Use ClonBrowser

Don’t you know ClonBrowser yet? If you don’t already know the browser, that’s a shame.
