Digital fingerprints have gained more popularity in recent years. Many people consider it a valuable tool in the era of information. So, what is a digital fingerprint? How does this technology work?
If you are wondering about these questions, you have come to the right place. I will discuss the functions and features of this tool with insightful details. Keep reading to discover the answer.
What Is A Digital Fingerprint?
The digital fingerprint is a modern technology. It allows users to convert their data into digital assets. Thus, they can track and control their content on the Internet.
How Do Digital Fingerprints Work?
The primary purpose of this tool is to verify digital information. Its most popular use is to serve as a hash function. The fingerprint is compatible with various inputs, such as a file or a message.
You can create a unique fingerprint for these inputs. Thus, you can build a unique verification of its content. The fingerprint will change when there’s a tiny change in that piece of content.
Therefore, users can keep track of their data more effectively. They can quickly know if someone has modified their information. Also, this tool can help check the authenticity of the senders.
For example, you can create a signature using the private key of the sender. The next step is to check whether it matches the sender’s hash. A matching result will confirm the authenticity of the sender.
The core advantage of this tool lies in its small size compared to the original size. Thus, users can quickly store and transmit it without much effort. Meanwhile, it can work with files of very large sizes.
For these reasons, digital fingerprints are a valuable tool in many areas. They help check the authenticity of both data and senders. It can also secure messages and private information.
The Properties of a Digital Fingerprint
A digital fingerprint consists of many components. Most of them are extracted information pieces from your device and browser.
Here are some typical components of a string:
- IP address
- Clock information (it helps verify your location and address)
- The plugins of your browser
- Stack variation
- The fonts installed on your device
- Flash data
- Timestamp
- Information relating to CSS
Two fingerprints can share similar components if these details match. Yet, the probability of another person having the same fingerprint as yours is very tiny.
In addition, tools like “adblocker” cannot remove fingerprints. The online services can always recognize you when they identify your fingerprints. Thus, they can keep track of your activities on the Internet.
Are Digital Fingerprints The Same As Cookies?
The features and mechanism of this tool are different from cookies. Yet, these two technologies serve a similar purpose. People believe that fingerprints will replace cookies in the near future.
The main use of cookies is to store information about specific content. It can save that piece of information in a web browser. Thus, users can retrieve it whenever they want. Yet, this technology has gradually become obsolete.
Users also don’t like cookies on their browsers. They have found many apps to block cookies from their sites. This task can be done on almost all browsers.
Cookies have been the leading tool in the tracking industry for many years. Yet, the presence of digital fingerprints will soon change this situation.
Unlike cookies, fingerprints are much more complex to block. Users have to perform a bunch of steps to remove this tracking tool from their browsers.
Limitations of Fingerprinting
The problem occurs when users use multiple browsers on the same device. This makes it difficult to class between these tools. Users with minimum setting changes can also reduce the effectiveness of this tool.
The Benefits of Digital Fingerprint
There are two main drivers for the wide use of this technology. The first reason lies in its effectiveness in tackling online fraud. The tool is also super valuable in the marketing field. Scroll down to see more!
In Anti-Fraud
The frauds on the Internet often fake identities. They use popular tools like VPNs to fake their addresses. The fingerprints can find out their exact locations.
In addition, fingerprints are very hard to tamper with. You will get spotted when making even a tiny change to the inputs. Therefore, fingerprints have become a favorite tool of many websites and services.
They can block and blacklist many devices with malicious intentions. Also, these sites can spot and ban media bots from accessing their domains.
In Marketing And Advertising
Fingerprints help marketing services identify users’ needs without using cookies. They can also track users’ activities across different devices. Thus, they can develop more effective marketing strategies.
The Negative Side of Digital Fingerprint
You cannot confirm how people use this tool. Malicious sites can take advantage of this tool and violate your privacy. They can also use it for their own benefit.
For example, many gambling sites have been using tools to track betters with high winning rates. Thus, they can block them from their sites before they can place a bet.
How To Protect Yourself From Digital Fingerprinting?
This technology is the best tool for tracking users’ activity. The measures to increase privacy cannot tackle it. For example, you cannot remove fingerprints via the settings.
The “do not track” mode doesn’t block this tool from your browser. Special tools and incognito mode also have no use in blocking fingerprinting services.
Your only option is to disable WebGL and Flash on your browser. Yet, this measure will cause some inconveniences during your web browsing time. It may also reduce the renders and usability of your websites.
In addition, your browser cannot save cookies after each update. So, it’s not the best solution for normal web users. A viable way is to use browsers like Tor.
These browsers have tools for tackling fingerprints. The developers choose a simple approach by giving all users the same fingerprint. Thus, your fingerprint will not change even when you switch to another device using Tor.
Final Thoughts
In summary, the digital fingerprint serves as a digital identifier. It helps the owner keep track of their copyrighted creations on the internet.
