Hi, I just found out my dentists office is using a program called "Second Opinion" produced by "Hello Pearl". There is literally no information about what this company does in the background with my information, however I know they at the very least have:

1. My full legal name
2. X-Rays of my teeth

I'm concerned because there is literally nothing online about how to opt out of them using your data for AI training. They are an AI company and the screen the Dentist was showing me showed a pop-up about provides information being able to be used for AI training. What should I do, what are my rights?

I've just been playing around with https://browserleaks.com/fonts . It seems no web browser provides adequate protection for this method of fingerprinting -- in both brave and librewolf the tool detects rather unique fonts that I have installed on my system, such as "IBM Plex" and "UD Digi Kyokasho" -- almost certainly a unique fingerprint. Tor browser does slightly better as it does not divulge these "weird" fonts. However, it still reveals that the google Noto fonts are installed, which is by far not universal -- on a different machine, where no Noto fonts are installed, the tool does not report them.

For extra context: I've tested under Linux with native tor browser and flatpak'd Brave and Librewolf.

What can we do to protect ourselves from this method of fingerprinting? And why are all of these privacy-focused browsers vulnerable to it? Is work being done to mitigate this?

Some talk about the privacy of the digital euro has been made. Some people said that your transactions are going to be tracked. Should an european worry about it? Would GNU Taler be a possible solution?

And it's not like the digital euro is some dream, it will become reality soon.
