I have been trying out the different security levels of the Tor Browser. It's set to Standard by default. Some people say that it is best to leave it as it is because most of the Tor users will have the default settings so you will blend in better. However, I decided to look at the other options.

I tested Tor browser with all three security level settings to see which one is the most commonly used through Cover Your Tracks for the most common Tor fingerprint.

On the default security level, Standard

Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 694.64 browsers have the same fingerprint as yours.

Currently, we estimate that your browser has a fingerprint that conveys 9.44 bits of identifying information.

Be aware that this does not block WebGL unique fingerprinting.

Now the security level in between, Safer

Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 1804.18 browsers have the same fingerprint as yours.

Currently, we estimate that your browser has a fingerprint that conveys 10.82 bits of identifying

The number is largely tripled from the standard mode. This security level is the least used and the most uncommon, which makes the browser less common with the others. I'm surprised that this is the most uncommon as it blocks WebGL fingerprinting.

The most effective safety level, Safest

Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 255.02 browsers have the same fingerprint as yours.

Currently, we estimate that your browser has a fingerprint that conveys 7.99 bits of identifying information.

This setting is surprisingly the most common and used one, even though it is not the default setting. It also disables Javascript to prevent the intense fingerprinting.

Disabling Javascript in Tor will not make you stand out, it will make you blend in the most and will block much more effective fingerprinting. Note that most websites will not function properly if JavaScript is disabled.

There is this carrier I stumbled upon called Cape, calls itself America's privacy first carrier.

It claims to offer privacy and security and to only store necessary information.

We don’t collect your name, social security number, address, or other personal information. Any data we do receive (like call logs) is deleted after 60 days.

We secure your account against SIM swaps—attacks to steal your phone number and access your accounts—with modern cryptography protocols.

Our proprietary signaling protection blocks attempts by bad actors to intercept calls and SMS via outdated signaling protocols like SS7.

Voicemails can hold sensitive information like 2FA codes. Cape encrypts your voicemails so only you have access to them.

We don’t collect your name or billing address at checkout, and Cape never sees your credit card details.

Anonymous sign-up

They are also partnered with Proton

Here is a detailed list of what data they collect

They are currently offering a $1.50 trial for one month.

The CEO, John Doyle, was a communications specialist in the U.S. Army and worked for Palantir.

Thoughts?

When you send a screenshot (even if height/width only is cropped) , the screenshot's width and height can be used to find the iPhone model of someone or narrowed down.

The most unique sized iPhone on the market right now is the iPhone 16 Pro and iPhone 16 Pro Max, as no other phone has the same width and height. So if you send a screenshot people will 100% know your exact phone. The regular iPhone 16 is common with the rest of the other phones and not unique.

If you send a screenshot from a iPhone XR, people can know if you using an iPhone 11 or iPhone XR since they have the same dimension which narrows down alot of options. (828x1792)

You can use this site here to view a list of all the dimensions. Click the iPhone's tab and sort the physical width or height.

If you don't want to expose your phone model, crop both width and height of each screenshot randomly. I would suggest cropping out the top of the phone as it shows your time if you care about that. Some sites like X have random inaccurate dimensions in uploaded screenshots, which is different from the original raw screenshot.

I haven't really checked with android phones, but it's probably the same thing.
