We are all using the internet to get the latest information throughout the globe.
And to do that, we are using software called web browser for us to be able to see websites that contains different information.
Due to some security issues, we try to hide our online identity to protect our privacy. We normally do this by clearing our browsing history, deleting cookies, clearing browser cache, and etc. But wait, these actions doesn’t guarantee that you’re not traceable anymore.
If you can just imagine, every time you visit a website- your browser sends different information from your PC to the web server. There’s what we call a User-Agent string, which contains name, operating system, browser’s version, etc.
The Electronic Frontier Foundation (EFF) is currently having a privacy research effort to measure the amount of information being conveyed by web browsers. The project is called Panopticlick.
The Panopticlick tells you how traceable you are based from estimated bits of identifying information from you browser fingerprint. Take a look at the screenshot below when I check my browser’s traceability using Panopticlick.
