Along with the development of Internet technology, websites and applications employ more and more advanced fingerprinting and MAC address detection techniques to track users and identify them. Among them, Canvas fingerprint a common advanced fingerprinting detection technique, while MAC address is the unique identifier of a device. In this article, we will find out how Canvas fingerprint and MAC address work and introduce some methods to stop websites from detecting Canvas fingerprinting.
What is a Canvas fingerprint?
A Canvas fingerprint is a unique identifier of a user generated by drawing an image through the browser’s Canvas API. Fingerprints are unique across devices and browsers, and the Canvas API allows websites to draw images on the client side without the need for a plug-in. By drawing a specific image and measuring the pixels of the image, the site can capture some other fingerprint information about the device and browser, and then generate a unique fingerprint of the user to accurately identify the user.
In addition to Canvas fingerprint, websites may also detect other advanced fingerprinting information, such as font fingerprinting, AudioContext fingerprint, WebGL fingerprint, media device fingerprint, and so on, based on which they can locate the user more quickly and accurately.
What is a MAC address?
A MAC address (Media Access Control Address) is a unique identifier for a device that is used to identify the device on a LAN. Each device has a unique MAC address, consisting of a 48-bit binary digit, usually expressed in hexadecimal form. Currently many websites or platforms detect MAC addresses and thus determine the association of multiple accounts.
How to Block Websites from Detecting Canvas Fingerprints and MAC Addresses?
Using Privacy Mode or an anonymous browser can help you prevent websites from detecting Canvas fingerprints and MAC addresses:
1. Privacy Mode prevents websites from recording your browsing history, cookies and other tracking data, but this only reduces the effectiveness of Canvas fingerprinting detection. Using a browser such as MuLogin Fingerprint Browser is a highly anonymous browser tool that will perform Canvas hardware fingerprinting protection by enabling Noise Mode to block Canvas fingerprinting detection.There are four noise modes included in MuLogin, each with a different effect. If you want a website to read your Canvas fingerprint, you only need to enable any one of the three noise modes A/B/C, and the website will read a disguised Canvas fingerprint, and cannot read the real fingerprint graphic. If you want to completely disable the website from getting the canvas fingerprint, you can also choose the blocking mode, then the website will get a null value.

2. For MAC address anti-detection, simply turn on the Anti-leakage setting when creating a browser in MuLogin Browser, including the computer name and MAC address, which the user can choose to customize and modify or randomly generate. This way the website will not be able to read the real MAC address. As shown below (source MuLogin client):
Protecting personal privacy is one of the most important tasks in today’s digital age. Understanding how Canvas fingerprinting and MAC address works is crucial when dealing with advanced fingerprinting and MAC address detection on websites. Taking a number of measures and using a fingerprinting browser is an effective way to effectively block website detection.
