## What is Canvas Fingerprinting?
Canvas fingerprinting is a technique that is being utilized for tracking users over the Web with the help of HTML5 Canvas elements in the Web pages. With totally unique identification, it will recognize you every time and hence track you. Here’s how it works:
1. **Canvas Element**: The HTML5 Canvas element can be considered a graphic painting element that is utilized for the painting of uien web pages. It opens up the possibility to display many different types of visual content, including text, shapes, and animations.
2. **Different Rendering**: Canvas element rendering is different for different hardware and software configurations for a browser, such as in font sizes, line thickness, and shadow effects, which makes these small differences.
3. **User Fingerprinting**: While doing this type of analysis of graphics rendering, canvas fingerprinting comes out with a unique ID representing individual users. This is 99 percent accurate in comparison to cookies or IP addresses, even in cases where the user has disabled the cookies, or the user has anonymized the IP.
4. **Data Extracted**: Data extraction with Canvas fingerprinting is regarding the device model, browser type/version, OS, and screen resolution. It also identifies the time zone, user agent string, language settings, plugins, and extensions.
## Pros and Cons:

2. **Privacy Mode**: Use private browsing modes to drastically reduce tracking.
3. **Regular Clearing**: Clear cookies and browser data at some regular intervals.
4. **Security Software**: Consider security software that can detect and mitigate fingerprinting.
