Good day,

as far as I know, there is at the moment no way of accessing hardware information on such a “low level” over for example a browser. Neither JavaScript, nor any other often for tracking used programing language, which you can run in your browser, is capable of doing this. So, unless you mail someone your log files or give him access to your system (two things which should never be done) you should be fine.

Have a nice day,

Most likely very much negligible, because we likely never get to
obfuscate the others so this one would really matter.
