I would say that differentiating between fingerprinting and legitimate use of the readout API is impossible without a full static code analysis which would make your browser incredible slow - especially while looking at PDFs.
The notification also is not meant to be an accuse but an information that a call to the readout API did not return the real values but some faked ones.
I tested with https://browserleaks.com/canvas and even when the "Signature" changes everytime I reload the test the "Unique Fingerprints" at "Database Summary" is always the same. Why? is this a way they can still track me??? I might improve the rate after clarifying. Thanks
Actually I'm not sure what the section "Database Summary" is all about and whte the "Unique Fingerprints" really count. Maybe they only include fingerprints in their database when they see it more than once (or the count is not live but only updated in some time periods). As the signature changes every time CanvasBlocker is working as intended. This is the tracking information CanvasBlocker protects.
Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss the impact of that (communication is way better there).
