Many friends have a question when using a fingerprint browser: Is the generated fingerprint real and reliable?

Judging the authenticity of a fingerprint is actually not complicated. You can use a fingerprint detection website to check whether the generated environment fingerprint matches the actual device data. However, sometimes even when using a fingerprint browser, third-party detection websites still prompt "environment is not clean." Why is that? And how to fix it?

This article will discuss how to use fingerprint detection tools to verify the authenticity of browser fingerprints, as well as the reasons for detection anomalies and their solutions.

How to Evaluate the Authenticity or Quality of a Browser Fingerprint?

There are many fingerprint detection websites on the market. Here are two recommended ones:

1. BrowserScan

BrowserScan is one of the most comprehensive browser fingerprint testing tools. It provides an advanced method to analyze browser fingerprint information in detail, including browser version, IP address, geographic location, screen resolution, fonts, plugins, and over 50 attributes. It can also detect whether WebRTC leaks the real IP address to help users assess privacy risks. In addition, BrowserScan offers practical features such as IP address lookup, DNS leak test, bot feature test, TLS fingerprint test, cookie conversion, and port scanning.

How to specifically evaluate the fingerprint generated by a fingerprint browser?

We can verify the fingerprint generated by NexBrowser through BrowserScan. Create and open a browser environment in NexBrowser, then visit browserscan.net to view the complete fingerprint report.

BrowserScan will quickly detect, giving you a general understanding of the current browser fingerprint. If some fingerprint parameters are abnormal, they are usually marked in red.

The main information includes:

• IP address
• Postal code of the IP address location
• Geographic location of the IP address (country, latitude, longitude)
• Time zone of the IP address location
• ISP of the IP address
• Browser version used
• Operating system of the current device
• Whether a proxy server is being used

Additionally, BrowserScan provides an authenticity score for the browser fingerprint. If it is below 90%, it indicates potential anomalies or leakage risks, and it is recommended to further check the detailed fingerprint information.

2. BrowserLeaks

Another fingerprint detection website is BrowserLeaks, used to detect various privacy vulnerabilities of browsers. It provides browser fingerprint analysis, covering Canvas, WebRTC, screen resolution, font fingerprint, and many other aspects.

Why Do Third-Party Detection Websites Show Fingerprint Anomalies? How to Solve?

First, through BrowserScan, it can be verified that NexBrowser generates unique browser fingerprints for each account. The cookies, cache data, browser plugins, and browsing history of each browser environment are stored in separate folders, achieving more thorough data isolation. In this way, your multiple accounts are like logging in on different computers, non-interfering and completely independent.

However, sometimes even when using the NexBrowser fingerprint browser, third-party detection websites still prompt fingerprint parameter anomalies. This situation can be caused by various reasons. Here are some common causes and solutions:

1. Fingerprint Parameter Inconsistency

If fingerprint detection fails, it may be due to differences between the generated environment and the real situation, causing the detection tool to find inconsistencies. For example, the User-Agent string does not match the kernel version, leading to detection failure.

Solution: Check the fingerprint browser settings to ensure that the generated UA string matches the kernel version. In NexBrowser, update the kernel version or adjust the UA settings to ensure consistency.

2. Different IP Databases

If IP detection fails, it is usually because different detection websites use different IP query channels and technologies, resulting in different detection results.

Solution: Choose a proxy service provider with high update frequency and good accuracy to reduce the chance of being misjudged by detection websites. In NexBrowser, you can change the IP database in the "IP Query Channel" settings.

3. GPU Information Mismatch

Sometimes hardware detection anomalies occur. For example, when a fingerprint browser uses the User-Agent of Mac OS, if it does not simulate the real GPU information of an Apple computer, the hardware fingerprint information will not match the User-Agent information.

Solution: Ensure that the hardware parameter settings of the fingerprint browser are consistent with the target device. If the fingerprint browser supports custom hardware parameters, you can manually adjust GPU information and other parameters. For example, in NexBrowser, you can customize WebGL metadata by setting "Vendor" to "Apple Inc." to simulate real GPU information. Enabling WebGL image noise can also add interference in image rendering, masking the real WebGL features and making the fingerprint harder to detect.

4. Plugin Interference

Some third-party plugins modify browser parameters and may override the configuration of the fingerprint browser, causing parameter conflicts. Some plugins themselves can become part of the fingerprint, altering browser behavior.

Solution: Avoid using plugins that change browser behavior or add unique request headers. Ensure that plugins do not affect fingerprint consistency due to being outdated or improperly configured. Try disabling conflicting plugins and retest with BrowserScan.

5. Improper Fingerprint Browser Settings

The settings of the fingerprint browser may not be natural or appropriate, leading to abnormal feature combinations that trigger detection tools.

For example, BrowserScan checks whether WebRTC exposes the real IP address, because WebRTC can leak the IP. As shown in the figure, the IP address accessed by BrowserScan is from the United States, but WebRTC leaks the real IP address (Singapore). This abnormal browser fingerprint will arouse suspicion from the platform.

Solution: Check whether the IP address matches the proxy, and confirm whether WebRTC leaks your real IP address.

You can also use NexBrowser's WebRTC blocking mode, which prevents websites from reading WebRTC parameters.

At the same time, choose a technically mature fingerprint browser. For example, NexBrowser can simulate various browser and operating system fingerprints and allows you to customize fingerprints based on business needs, reducing the risk of being tracked.

Final Thoughts

If you currently want to verify the authenticity of a fingerprint, you can use tools like BrowserScan to detect it. Based on the detected anomalous information, use different solutions to solve the problem, ensuring your account environment is more real and secure.

Additionally, to make the browser fingerprint cleaner, choosing a reliable fingerprint browser is very important. It is recommended to use NexBrowser to generate an independent browser fingerprint for each environment to reduce the risk of fingerprint anomalies and ensure the browser environment is both authentic and resistant to detection.
