Video Lesson: Basic Concepts and Types of Digital Identities

This video lesson provides an introduction to the concept of digital identity and explains the basic concepts related to its creation, use, and protection in the modern digital environment. The video lesson presents various types of digital identities:

• Personal digital identity – data and online presence related to an individual in their private life;

• Professional digital identity – an online profile and activities connected to the professional or business environment;

• Anonymous digital identity – an identity that does not reveal a real name or personal data;

• Institutional digital identity – an identity assigned by an organisation or institution to access its systems and resources;

• Financial digital identity – data and credentials associated with financial transactions and services;

• Biometric digital identity – an identity based on biometric data such as fingerprints, facial recognition, or voice recognition;

• Social digital identity – presence and interaction on social networks and online communities.

The lesson emphasises the importance of secure management of digital identities and explains how irresponsible handling can lead to identity theft, breaches of privacy, or financial harm.

A digital identity refers to a set of digital data that uniquely identifies a person, organisation, or device in the virtual space. This includes, for example, usernames, passwords, biometric data (such as fingerprints, facial recognition, or movement patterns), digital certificates, IP addresses, and records of online activity. Unlike a physical identity, a digital identity is used to access online services, communicate, perform transactions, and manage security in the digital environment.

Digital identities appear in various forms, ranging from simple user accounts to complex authentication systems that use multiple factors (such as passwords and biometrics). They are used in almost all activities in cyberspace: logging into email, accessing business systems, online banking, social media, or using smart devices. In the context of cybersecurity, a digital identity is a central element as it enables access control and prevents unauthorized intrusions into systems.

Secure authentication and identity management help defend against attacks, such as identity theft, phishing, or malicious account takeover. The connection to data protection is evident in the need for secure storage, processing, and use of user identification data. A digital identity must be protected to prevent misuse and safeguard individual privacy, which is also legally mandated by the GDPR regulation. In the digital age, the protection and management of digital identities are fundamental to maintaining trust, privacy, and security in all aspects of online life.

A personal digital identity refers to a set of information that enables the recognition and authentication of an individual in the digital environment. This identity includes data such as usernames, passwords, biometric information, electronic addresses (e.g., email), and details of online activities (e.g., social media, online shopping). A personal digital identity allows users to access services and platforms, such as online banking, e-commerce, and educational systems. A key characteristic of a personal digital identity is that it enables secure access management while protecting the user's privacy, reducing the risk of unauthorized access and data misuse.

A professional digital identity refers to a set of information that represents an individual in a professional context within the digital environment. This includes data such as professional biographies, work experience, skills, academic and professional certifications, and activities on business networks like LinkedIn. A professional digital identity may also include personal websites, portfolios, reviews and comments from colleagues, and participation in online communities or industry forums. This identity helps shape professional reputation and enables networking with colleagues, employers, and partners, while simultaneously contributing to recognition and legitimacy in the professional sphere.

An anonymous digital identity is an identity in the digital environment that does not reveal the user's true identity. This form of identity allows users to communicate, browse the internet, and engage in online activities without disclosing personal information such as their name, address, or other identifying details. Anonymity can be achieved through the use of pseudonyms, virtual private networks (VPNs), privacy protection services, and tools like the Tor browser, which help conceal the user's actual location and identity. While an anonymous identity offers greater privacy and protection from tracking, it can present challenges in terms of compliance with laws and security protocols, as it may complicate accountability in the online environment.

An institutional digital identity is a digital identity associated with an organisation, institution, or legal entity in which an individual works, rather than with the individual themselves. This identity allows institutions to access various services and systems in the digital environment, such as government portals, business applications, or academic databases. An institutional digital identity may include information about the organisation, such as official registration details, business accounts, employee access privileges, and specific permissions related to the resources the institution uses. This identity enables organisations to securely manage access to data and resources, and collaborate with other institutions, while also protecting sensitive information from unauthorized access.

A financial digital identity refers to a set of data that enables the identification of an individual or organisation in financial transactions and services within the digital environment. This identity encompasses information such as bank account numbers, credit card details, identification numbers (e.g., tax identification number), transaction data, payment history, and credentials that provide access to financial systems such as online banking, payment apps, and financial services.

A financial digital identity enables users to securely carry out financial transactions, access financial services, and protect against fraud and unauthorized transactions. Due to its sensitivity, this identity requires a high level of privacy and security protection, including two-factor authentication and data encryption.

Biometric digital identity is becoming an increasingly important tool in ensuring security and privacy in the digital environment. It is based on unique characteristics of each individual that are difficult to forge, and these can be divided into physical and behavioural traits.

Physical biometric traits include fingerprints, facial recognition, iris scanning, and palm or footprint patterns. These are immutable and unique. A fingerprint remains unchanged throughout life and it is almost impossible for two individuals to have identical prints. Facial recognition analyses facial features, while iris scanning uses unique iris patterns specific to each person.

On the other hand, behavioural traits are based on how a person behaves, such as their walking pattern, typing style, or how they use a smartphone. For example, everyone has their own unique walking rhythm or way of using their voice. While these traits may vary slightly, they are sufficiently recognisable to be used for authentication.

Together, these biometric features enable the creation of a secure digital identity that is not only credible but also difficult to forge. In an era where cyber threats are a daily reality, biometrics becomes a powerful ally in protecting personal data and accessing digital services.

A social digital identity refers to a set of data that represents an individual in the context of their presence on social media and other online platforms. This identity includes information users share through their social profiles, such as name, photos, biographical details, interactions with other users (comments, likes, posts), and information about interests and behaviours.

Social digital identity plays a crucial role in shaping online reputation, as it is often the first impression that other users, potential employers, or partners may have of a person. Additionally, this data can be used for targeted advertising and personalised services.

Digital identities form the foundation for secure and trustworthy participation in the digital environment, and understanding and properly managing them is essential for protecting personal data and ensuring digital security.
