Create browser fingerprint

Question

I wish to create a browser fingerprint for every user on my website. I do this by iterating trough winow.screen window.navigator object properties. I copy them to an object.

The problem is at window.navigator.plugins when I use JSON.stringify I don't get the filename of plugins installed. The property is there but somehow is not serialized using JSON.stringify.

The object is like this window.navigator.plugins[0].filename

How can I get all object content using stringify ?!

Answer 1

This will turn it into an array and extract only the filename from there, which can then be stringified properly:

[].slice.call(navigator.plugins).map(function(plugin){return plugin.filename})
JSON.stringify([].slice.call(navigator.plugins).map(function(plugin){return plugin.filename}))
