Software Usage Instructions

Set detection items: After entering the tool, first select the dimensions to detect, including Canvas, WebGL, Audio, fonts, screen, time zone, plugins, media devices, storage, ClientRects, WebRTC, and more.
Adjust parameters: You can set the report name, hash display length, default similarity threshold, Audio detection mode, font detection range, and WebRTC wait time. Click “Save Settings” to keep the current configuration.
Generate a fingerprint report: Switch to the “Generate Report” step and click “Start Detection”. The tool will calculate fingerprint hashes item by item and generate a combined SHA-256 hash, risk score, estimated entropy value, and category details.
View category results:
- Combined fingerprint: Calculated from all enabled dimensions to represent the overall characteristics of the current environment.
- Category cards: Display the independent hash, status, entropy value, and key parameters for each dimension.
- Canvas preview: Shows the Canvas drawing sample from this test, making it easier to verify rendering differences.
Export results: You can download the complete JSON report or a CSV summary for archiving, retesting, or importing for batch comparison.
Batch comparison: Go to the “Batch Comparison” step, import multiple JSON reports, set the similarity threshold, comparison mode, and participating dimensions, then click “Start Comparison Analysis”.
Download comparison report: After the analysis is complete, you can download the comparison JSON or ZIP archive. The ZIP includes summary results, a CSV of similar combinations, and each report file.

FAQ

A: A device fingerprint is identifying information formed by combining multiple characteristics such as screen, fonts, graphics card, audio, time zone, plugins, and more. A single characteristic may not be obvious, but a combination of multiple characteristics can be highly distinctive.

A: Canvas detection focuses on rendering differences of text and graphics on the canvas; WebGL detection focuses on GPU, drivers, graphics capabilities, and rendering parameters. Both may reflect differences in hardware and system rendering environments.

A: No. By default, the tool uses offline audio rendering to calculate audio processing results, so it does not need to actually play sound. If compatibility limitations occur, you can also switch to basic parameter mode.

A: The risk score is a reference value calculated based on enabled dimensions, estimated entropy, completion status, and restricted items. It helps determine whether the current environment characteristics are easy to distinguish. The score is for analysis only and is not equivalent to an actual tracking conclusion.

A: Batch comparison is suitable for comparing changes on the same device over time, similarities between multiple devices, differences before and after adjusting privacy settings, and analyzing whether multiple fingerprint reports contain related characteristics.

A: Factors such as system updates, font changes, resolution adjustments, changes in external devices, plugin changes, permission status changes, and privacy extension intervention may affect certain dimensions, so differences during retesting are normal.

A: No. Detection, comparison, example generation, and export are all completed locally on the current page. JSON reports and ZIP archives are generated by the user’s device.
