Unique canvas fingerprints will do much worse.
Is like you said you have a device that never exist.
To better understand how this work :
Google already have a full database with all kind of canvas signatures from all worldwide devices (iphone, android, computers, etc...), and if your canvas signature will not match on them database then you fail, it is a prove that your canvas is fake. If you try to spoof the signature then image pixel parameters will not match and again you fail so is almoust imposible to pass canvas.
On default settings may make it pass the google test.
For example google will not ask for SMS confirmation when a new gmail account is created because he trust the device you use.
Most of people must understand why unique signatures is bad practice and all softwares that spoof parameters will make traking services to detect the device much easy

posted 7 years agoPlease open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss this. AMOs rating comments are too limited to have a good conversation.
One small comment on unique signatures: they are not bad by itself as long as they are not persistend (i.e. the timestamp you connect to the server is very likely to be a unique signature but it's not persistent). This is the case in the CB default settings.

- Rated 5 out of 5by tutzlima, 2 months agoI use this extension together with "AmIUnique" and, based on this, i have no complaints. There were few moments that my fingerprint was collected by AmIUnique, but the *most* were specific moments that I turned off the canvasblocker for testing.

posted 3 months agoPlease open an issue at https://github.com/kkapsner/CanvasBlocker/issues to describe your issues with captchas.- Rated 5 out of 5by Ugarov, 3 months ago
- Rated 2 out of 5by blackSP, 3 months agoChecked before and after installing/activating this extension trying all profiles and see zero improvement in my identification score on several fingerprinting sites like coveryourtracks.eff.org and amiunique.org. Benefit of the doubt after reading dev's comment that it works anyway. Can't find any proof of that though.

posted 3 months agoYou need to check the details of the fingerprinting sites. Depending on your settings you can have a unique fingerprint - but this is not a bad thing if it changes: https://canvasblocker.kkapsner.de/faq/#uniqueFingerprint - Rated 5 out of 5by Firefox user 17902463, 3 months ago
