From what I briefly read about fingerprinting and its legality it mentions

Hi everyone I haven’t managed to find an open source solution to device fingerprinting which gives us everything we need. This library however gets us most of the way there http://valve.github.io/fingerprintjs2 < http://valve.github.io/fingerprintjs2>;. It doesn’t give us enough information to distinguish between a desktop and a laptop but it will let us correlate devices and we can distinguish between a PC, a tablet and a phone. We can also get the OS, Browser and Versions from the user agent string. I have taken a look at a few sites the track device sessions. Apple can tell the difference between an iMac, a MacBook, an iPad and an iPhone. Facebook, GitHub, Google, LinkedIn and Pinterest don’t distinguish between an iMac and a MacBook. So maybe the library above is enough. I also came across the following article from the EFF which casts doubt on the legality of digital fingerprinting in Europe. https://www.eff.org/deeplinks/2018/06/gdpr-and-browser-fingerprinting-how... < https://www.eff.org/deeplinks/2018/06/gdpr-and-browser-fingerprinting-how... > Does anyone have any input on any of this? Is there a better library that I have missed? Should we stick to parsing the user agent to avoid potential problems with GDPR?

The user agent will give us some device info too, it will allow us to distinguish between PC, tablet and phone in most cases.

I think this is my preference too. If we go this route should we use ua-parser (https://github.com/ua-parser <https://github.com/ua-parser>) and maybe enhance it or should we write our own parser? Ua-parser as it stands lists my Mac as “Other” for the device.
