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

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 Saint.77, 7 months agoOne of the essential plugins for everyone that care about anonymity when you surf on the web. If you stay on one of the 2 lowest settings you can increase your anonymity dramatically on the web without breaking functionality, so you can surf the web pretty much like everyone else without even noticing it while still staying hard to identify if you for example combine this with VPN. This alone will help but its one of several other key plugins you should install to shield yourself against tracking on the web.
