Digital Footprint on the Internet and How to Manage It

Across the vastness of the internet, our digital footprints are found everywhere. Internet giants, social networks, messengers, online stores, search engines, and other resources collect vast amounts of information about us. This treasure trove of data serves various purposes - from targeted advertising and content personalization to user behavior analysis, which can have potential implications for political or commercial manipulation.

What is a digital footprint?

How are we tracked on the internet?

Every click, every search, every interaction on the Internet leaves a digital footprint that reflects your journey through the web. It has many names: “digital footprint”, “digital imprint”, “digital shadow”, “cyber shadow”, “electronic trace”. This footprint grows with every post on social media, subscription to a newsletter, review left, or purchase made online. Often, this expansion happens without our awareness. Websites use cookies to track actions, and mobile apps can access data discreetly. If you give an organization access to your data, it may be sold or shared with third parties. In the worst case, this can lead to a data breach.

Digital footprints as a popular marketing tool

Marketers use the capabilities of digital footprints in many ways:

• Personalization of advertising
  By analyzing search queries, website visits, purchases, and other user data, companies tailor advertisements to individual preferences and interests.

• Audience targeting
  Digital footprints allow marketers to identify target audiences for advertising campaigns based on demographic data, geolocation, behavior, and other factors.

• Retargeting
  Users who visit certain websites or show interest in specific products are shown relevant ads, increasing the likelihood of return visits.

• Analytics and Optimization
  Data analysis helps assess the effectiveness of advertising campaigns, refine marketing strategies, and optimize online resources.

• Cross-selling and Upselling
  Understanding user preferences allows for targeted offers of complementary or premium products/services.

While this capability increases marketing accuracy and conversion, it also raises serious privacy concerns.

Digital footprint options and their distribution

• Active digital footprint:
  Creating profiles on social networks and messengers.
  Publishing photos, videos, and posts.
  Commenting on forums and websites.
  Subscribing to newsletters and feeds.

• Passive digital footprint:
  Visiting websites.
  Using search engines.
  Allowing apps to access geolocation data.
  Accumulating cookies and metadata.

• Mixed digital footprint:
  Online purchases, including personal data, order information, and payments.
  Use of mobile applications that collect both active and passive data.
  Registration on a website where activity is tracked not only by profile data.

Risks associated with the spread of digital footprints online

• Data leak:
  Actions on the Internet are recorded and stored, which, if mishandled, can lead to identity theft or fraud.

• Tracking:
  Digital footprints allow detailed tracking of movements, actions, and interests, which are used by both governments and corporations.

• Targeted advertising:
  Data-driven persistent advertising can lead to unnecessary purchases.

• Discrimination:
  Detailed profiles created from digital footprints can affect job or credit applications.

• Loss of control:
  After being posted online, information can be copied, modified, and distributed without your consent.

Security of digital footprints in messengers

Nowadays, messengers have become the primary means of communication, combining personal and business contacts. However, data security and privacy of conversations are always at risk. Below are the main ways in which attackers can hack your account in any of the messengers.

• Phishing
  Phishing is a method of social engineering where attackers create fake websites or send false messages to trick you into revealing personal information. For example, you may receive a message with a link to a site that looks like the official messenger site but is actually created to steal your information.

• SIM card swapping
  SIM swapping occurs when hackers trick the mobile operator into issuing a new SIM card with your phone number. Once they gain access to your number, they can intercept SMS messages with confirmation codes and log into your account.

• Spyware
  Spyware can be installed on your phone without your knowledge. This software can intercept messages, calls, and other data coming to your phone. It can be installed through malicious apps or infected files.

• Infection through public Wi-Fi networks
  Using public Wi-Fi networks can be dangerous, as attackers can set up fake access points within them. By connecting to such Wi-Fi, you risk giving hackers access to your data, including conversations in any application.

• Backup hacking
  Every app allows you to back up chats to cloud services like Google Drive or iCloud. If attackers gain access to your cloud account, they can download and read all your conversations.

• QR codes
  The web version of WhatsApp, Telegram, Viber, and other messengers uses QR codes for authentication. Malicious actors can create a harmful QR code that redirects you to a fake page or installs spyware on your phone.

• Direct access to the device
  If a hacker gains physical access to your phone, they can simply open any messenger and read all your messages. In some cases, apps can be installed that will transmit data in the background.

How to protect your data online

While it is impossible to completely erase your digital footprint online, you can minimize risks and enhance your privacy by following these steps:

• Be selective about data sharing:
  Carefully review personal information posted on social media and other platforms.
  Do not share digital data unnecessarily: phone numbers, addresses, and valuable financial information.

• Use privacy settings:
  Configure privacy settings on social networks and other accounts to control who sees your content.

• Manage geolocation data:
  Disable geolocation features in apps if they are not needed.

• Use specialized tools:
  Use VPN services to hide your IP address. A VPN hides your real IP address and your geolocation, providing anonymous access to the Internet.

A digital footprint is the information that remains after any of your actions on the internet, and managing it can be challenging. Every visit to a website, search, post, or purchase leaves a trace that can be used not only by marketers but also by anyone else who knows how to do it. That’s why it’s so important to keep an eye on privacy settings, limit the sharing of personal data, and use protective tools like VPNs.

However, it is worth remembering that if someone does not care about their security and leaves traces on the network, it becomes easier to track their location or access someone else's accounts. For example, vulnerabilities or neglecting security can allow others to intercept codes for logging into messengers and gain access to conversations. By managing your digital footprint, you can protect your data in messengers and your privacy while staying away from potential threats.
