Zero Width Fingerprint — Superior Analytical Technology
So now that you’ve read the title of this blog and are interested in understanding precisely what a zero-width fingerprint is , it won’t be long before you are witnessing with your own eyes what the public has to offer. This technology can perform .
To understand a zero-width fingerprint, we need to study zero-width characters. So, by the time Unicode was invented in 1991, it had provided a code system. International characterization facilitates the electronic exchange, processing, and display of texts written in various languages of the modern and classical worlds.
I’ve always thought that most programmers don’t know much about character encodings; that’s why I recommend you read this article on the absolute bare minimum you need to know about Unicode and its associated functions. Character set.
Some of these zero-width characters were invented for different languages required in their writing systems.
While these characters solve a significant problem in making the Internet globally accessible, they also pose a threat in the many different ways they can be used. One of the obvious ways is to use a zero-width fingerprint.
One can easily encode a secret message inside the seemingly simple text: a zero-width fingerprint using these zero-width characters.
Are you still confused?
Don’t worry! Figure it out using an example
Visit this site:
This site uses a basic form of zero-width encryption algorithm, also available in open source and can be made more complex if the user wants.
To show how it works, you will need to open the website, and you should see something like this:
In the first box, we have to enter the message that we want to show the user, and in the second box, we have to fill in the secret message that must be encrypted in the public notice.
When we click the steganographic button, we get the final encrypted text.
We can now copy this text and place it anywhere on the internet, any website, social media platform, or document. Any Unicode-based program will accept this text.
To display the encrypted message, simply go to the same web page, paste the encrypted text in the displayed text box, and click decrypt.
So! Your hidden text is now displayed
You may have been wondering about the potential uses of this technology. Let me introduce you to a few.
# Application 1:
Have you ever wondered who leaked a sensitive document in your organization?
Don’t worry; we present you with “The Trap of the Canary Islands.”
Use the Zero Width Fingerprint feature to hide the person’s name in the files you provide them. If these files are uploaded, just search for these hidden names in the file, and find out who is responsible for the leak.
Here is a diagram explaining how it works:
# Application 2:
Now is the time to realize the true potential of this technology. Through the use of zero-width fingerprints, sensitive information can be exchanged anywhere on the internet, whether it’s YouTube comments, Instagram posts, or even blogs like this. You can be as creative as you want by choosing the right platform.
Now you may be wondering why I should share information in this way and not just use email and other apps.
Now, the answer to that is surveillance. If you are a R.A.W agent and want to share information about your home, you know that phone connections and email services can track your real identity, and you could get arrested. With it, you can be as discreet as you want and use common means of communication such as texting and email.
Since most modern programs are created with the utf8 character encoding system, it is tough for most surveillance systems to detect your messages.
But if you still want to be even more secure with your communications, you can always encrypt the text before encrypting it at zero width.
This means that text like “Jai Hind” will first be encoded to text like “v3PnsqhgAry/Egwpo+m9JUmPw465ykOcRxFKTsPCtCc=” and then encoded at zero width. If your reader is intercepted, strong encryption prevents your confidential message from being exposed to unauthorized people.
So now that you understand how the widthless fingerprint works, I want to tell you about the potential dangers, it can bring.
If used as a communication tool by the illegitimate and criminal elements of society, tracking their movements and messages would become a nightmare for law enforcement officials, causing pose a threat to national security.
These encoded messages can be identified by machine-level code because even texts encoded with zero-width characters use extra bits than those used in the original text.
Although there are tools that check these encrypted messages inside the text like
Most of these means of text recognition are not used in practice by organizations running online communication protocols.
And that leaves a hole in the system that can be easily exploited.
I hope you’ve been able to catch up with me so far and have developed an understanding of what width fingerprints are. If you want to know more about how exactly this technology works. Stay tuned for the next blog.
To clear things up a bit, I coded a secret message somewhere in this post. Try to see if you can identify this post and post it in the discussion below.
