How to test if your browser configuration is unique – EFF Panopticlick – PET (Privacy Enhancing Technology)
We all use a browser, sadly our configurations are unique. This means that surveillance can fingerprint us, using the browser. This is scary stuff. EFF have devised a unique test – and alas it immediately fingerprinted me as unique.
Step 1 – Run the EFF Browser Test
Step 2 – Get your results
Rare configurations may function as fingerprints that allow websites to track the browser even if the user limits or deletes cookies
The results will detail a fingerprint of your browser.
Step 3 – How 3 or 4 pieces of meta data can uniquely identify you
Meta data cannot be “anonymised”. It’s a unique fingerprint that is incredibly dangerous.
The NHS and government always claim that their medical information has been “anonymised”, but if it contains both your date of birth, postcode and gender, then of course their claim is utter rubbish.
Meta data is far more damaging than actual content. Meta data cannot be “anonymised” in any context, from your web browser to your medical records. So if anyone claims they have allowed access to “safe” anonymised medical data they are trying to hoodwink you. The “it’s been anonymised” argument… is mathematical rubbish.
The EFF are demonstrating this with your browser.
The EFF browser uniqueness pdf makes interesting reading. The “take home” message is that data cannot be anonymised. It only takes 3 or at most 4 sets of meta data to uniquely identify everyone on the planet. If the data contains 3 data sets – it cannot be anonymised.
1. Install NoScript for your browser. This makes a significant difference… you should no longer have a unique browser.
