Merry Christmas 2018!

Luke 2:8-20    New American Standard Bible (NASB)

8 In the same region there were some shepherds staying out in the fields and keeping watch over their flock by night. 9 And an angel of the Lord suddenly stood before them, and the glory of the Lord shone around them; and they were terribly frightened. 10 But the angel said to them, “Do not be afraid; for behold, I bring you good news of great joy which will be for all the people; 11 for today in the city of David there has been born for you a Savior, who is Christ the Lord. 12 This will be a sign for you: you will find a baby wrapped in cloths and lying in a manger.” 13 And suddenly there appeared with the angel a multitude of the heavenly host praising God and saying,

14 “Glory to God in the highest,
And on earth peace among men with whom He is pleased.”

15 When the angels had gone away from them into heaven, the shepherds began saying to one another, “Let us go straight to Bethlehem then, and see this thing that has happened which the Lord has made known to us.”16 So they came in a hurry and found their way to Mary and Joseph, and the baby as He lay in the manger. 17 When they had seen this, they made known the statement which had been told them about this Child. 18 And all who heard it wondered at the things which were told them by the shepherds. 19 But Mary treasured all these things, pondering them in her heart. 20 The shepherds went back, glorifying and praising God for all that they had heard and seen, just as had been told them.

Browser Fingerprinting: What Is It and What Should You Do About It?

A web browser fingerprint is the identification of someone’s web browser in an attempt to track you regardless of what IP address you are coming from.

Basically your web browser is probed to determine what add-ons you have installed, what fonts are installed on your computer, what video card your computer has (via WebGL), PNG hash, what operating system you are using, your web browser’s 2D canvas, etc. All of this information is combined to form a fingerprint of your web browser.

Now you may be asking, “How does this allow someone to track my online visits?”  Good question.  People can make use of this fingerprinting to track you even if you take measures to deter people from monitoring your online activity (e.g., using a VPN).

If you have ever visited a website (without using a VPN) and later on you visit the same website (this time, using a VPN), they can still have a pretty good guess that it is you just by looking at your browser fingerprint you left the last time you visited (without the VPN).

This is how websites like YouTube still show you relevant recommendations, even if you use another IP address to access their web service.

Is there any way to stop browser fingerprinting? Not really. You can help confuse trackers into thinking you are someone else by spoofing the fingerprint, but this is not guaranteed to always work.

A browser fingerprint spoofer basically “lies” to a website giving it false information about the web browser. This of course causes the fingerprint to be different than it normally would be. The result? A website thinks you are someone else regardless of the IP address you are connecting from.

(This does not take into account tracking cookies. Websites can also track you with cookies, regardless if they use web browser fingerprinting techniques.)

So what do I recommend to do to help stop browser fingerprinting? Well you can do the following (my opinions, of course):

That should help protect your real fingerprint from being found out. I should note that spoofing your fingerprint may end up breaking certain websites. You will just have to try it out.

Please keep in mind, a browser fingerprint spoofer can end up making your fingerprint unique to everyone else’s fingerprint. This can cause you to stand out like a sore thumb, and cause you to be even more easily tracked. 🙁

This is because most people are not using a fingerprint spoofer and it would become obvious that you (and maybe a couple of other people) are the only ones faking your browser fingerprints. In other words, you do not “blend into the crowd”.

Another trick is to turn on Mozilla Firefox’s “resist fingerprint” feature. This feature, among other things, causes your web browser’s fingerprint to match that of the TOR web browser. This makes you blend into the crowd of TOR users, since they all should be using the same fingerprint.

To turn this feature on:

  • at the about:config webpage (on Firefox), find the option privacy.resistFingerprinting and set it to true, then restart the web browser

However this feature (in my experience) causes some websites to break (animations are slowed down, current time of day will not be correct, etc.) This all helps to prevent websites from fingerprinting the browser.

Please remember that there is no way to be 100% anonymous on the Internet. Always someone out there who can track you. All you are doing is making it harder to be tracked.

I hope I have helped someone with this blog post. It took me a bit to write it, but it is worth it if it helps. 🙂
