Device Fingerprint - http://noc.to
My site's code is now published here so others can learn from it. Hopefully, I will also learn from your feedback. Use of any portion of the code in commercial tracking systems is not authorized. If you test the code, please do so from a private IP or use a blocking robots.txt. Clone websites would be bad for my already low search rankings. :)
Naming in the code: A Device entity represents the information gathered during a single page load. The website user interface now uses the word "imprint" instead of "device".
Github's issue tracking is available to report problems, make suggestions, or feature requests.
