inject-fingerprint

inject-fingerprint

Inject fingerprint with proxy.

Fingerprint (device fingerprint) is a set of techniques that allow a website to uniquely identify your computer.

Calculating a device's fingerprint begins when a user visits a website. The device fingerprint tracker collects all relevant information (version / browser type, OS, etc.). The interaction triggers the collection of a range of data (like the one listed above) that forms a special "hash" assigned to that specific device.

This page tells you how identifiable your browser is as a robot: https://bot.sannysoft.com/ and this module makes the tests on this page succeed on your chrome headless. See test

Install
