How Do VPNs Hide Your Identity? IP Masking Explained

Each time you access the internet on a Wi-Fi network through a coffee shop nearby or any website from your own home, your digital footprint is going to leave behind traces of information that are traceable back to you. 

Websites, ISPs, network administrators, and even third-party advertisers are constantly tracking your connection and collecting online behavioral data to build your consumer profile. Understanding How Do VPNs Hide Your Identity? explains how Virtual Private Networks can create a secure barrier for you digitally. 

Through encryption and routing of connections through remote servers, such services hide your personal information and allow regular internet users like yourself to maintain your privacy online.

The Basics: The Operation of Virtual Private Networks

In essence, a virtual private network is a safe and encrypted channel that extends from your computer to the internet. In regular networks, your browsing activity flows openly via your router and your ISP’s servers, exposing the addresses to which you connect and your search inquiries.

If you establish your private network, your computer will first encode all data packets. Then, the encrypted data goes to a remote VPN server in the city or the country of your choice. There, the server decodes your request, connects to the website you address, and sends the answer back to you.

What Info Does a Virtual Private Network Conceal?

By manipulating data transfer processes, security software hides essential identifiers that are usually used to identify your online presence:

• Actual IP Address: An IP address is similar to a physical address, which identifies you as the sender of the request to browse a particular website. The virtual private network substitutes your own IP with the virtual one provided by a remote server.
• Actual Geographic Location: Since the servers’ location is detected by the web resources you interact with, your geographic location remains undisclosed.
• History of Searches and Browsing Activities: Encrypted connections help to avoid the collection of information about the websites you visited and the queries you performed by your ISP or any other party on the network.
• Details of P2P File Exchange: Hiding network nodes’ addresses prevents third parties from discovering your actual IP address while downloading files.

Main Technologies That Protect Your Privacy

A combination of several technologies is used to ensure the anonymity of the user over both public and private networks:

• End-to-End Data Encryption

  Advanced virtual private networks utilize highly secure encryption protocols, such as AES-256, to encrypt all the incoming and outgoing data. Even if some cyber-criminal will be able to get access to your network packets in a public Wi-Fi hotspot, for him these packets will appear to be unreadable without having the particular decryption key.

• Private Domain Name Server Lookup

  Standard requests to the DNS server are sent to the DNS server that is managed by your local ISP, thus registering each of your domain name requests. The most advanced private networks utilize their own encrypted channels for DNS request processing.

• Automated Kill Switch

  If the network connection breaks down, the kill switch will immediately block any network activity, thus protecting your IP address from being revealed.

Limitations of Private Network Privacy

Although a private network prevents your connection and network locations from being known, it cannot guarantee total digital anonymity:

• Sign-ins to Personal Accounts: Logging in to personal social networking sites, e-mail services, or banks automatically identifies you, independent of your IP address.
• Web Cookies and Tracking Tools: Web trackers, device fingerprinting technology, and browser cookies collect personal identifiers and keep them locally on your device.
• Identity Information: Online payment transactions using credit cards and completed web forms provide personal information directly to the vendor database.

Conclusion

To safely browse the internet, one needs to comprehend how personal information travels through digital networks. We have understood how encryption of web traffic and masking IP address provides the basic level of protection from internet surveillance, logging by ISPs, and exploitation of public networks.
