Help Needed: Analyzing Fingerprint Detection in BAS

[MAB Tech]

I was trying to analyze fingerprint detection on a website using BAS. When I used the Fingerprint Detector Tool in record mode, it captured multiple detections, including Canvas.

However, when I tested the same website using BabloSoft Canvas Inspector v3.0, it did not detect any canvas request or fingerprinting attempt. Then, I tried using the Perfect Canvas module, and it did detect a canvas request.

Now, I am confused about whether the Perfect Canvas module is still working correctly and up to date. Is it fully reliable for detecting canvas fingerprinting, or is there another better method to analyze this?

Additionally,

• Does Canvas Inspector v3.0 not work perfectly?
• Is there a way to save detected fingerprinting requests (such as font, language, canvas, etc.) in a pack format using the Fingerprint Detector?
• Can we later use this saved fingerprint pack to request a new fingerprint using Perfect Canvas?

I also noticed that the Canvas Inspector 3 tool does not detect some of the canvas requests. More details here: https://community.bablosoft.com/topic/29864/fingerprint-detector-sees-canva-fingerprinting-canvas-inspector-doesn-t

I would also be interested in knowing a way to save the detected cavas requests in the Fingerprint Detector

FingerprintDetector stores messages about any call to getImageData.

CanvasInspector excludes data with zero entropy, the result of which will be the same on any hardware.
