I guess mouse movements are a very good way to identify people across websites.

It's also an efficient way to distinguish people from machines. Think about the click-only reCaptcha for example.

I absolutely not believe that. for real. this is something i keep reading but a seriously not see how mouse movement can be unique from one person to another. it's not a fingerprint come on.

well that i can believe, but not more

Change mouse brand to surreptitiously become another person without telling a single lie or changing any normal user data :)

It's about the pattern of movement, not the brand of mouse. Identity identification algorithms are more robust than that.

I wonder to what degree DPI settings, tracking speed, and acceleration influence this. People will move their mice differently depending on how fast the cursor goes, and it's cursor movement that's being tracked, not physical mouse position.

How often would you be ready to change mouse brand?

Would you change mouse each time you change browser tabs, keeping a mouse for Facebook and a mouse for other websites?

Also, keep in mind mouse tracking is just another technique deployed to identify you. It's not supposed to be a silver bullet.
