Every day we interact with the digital world in an endless number of ways. From making online purchases to reading news, applying for jobs online, or using social media, to managing employees access to offices, access shared resources (e.g. printers, conference rooms\u2026), or even when opening a bank account, our digital identity forms a key aspect of these interactions, both in the online and in the physical world. But what exactly is a digital identity?<\/p>\n

Understanding Digital Identity: what is it?<\/strong><\/h2>\n

Defining Digital Identity is not a very easy task, as National Institute of Standards and Technology (NIST<\/a>) underlines in its Digital Identity guidelines<\/a>. In fact, digital identity adapts to different contexts, complicating efforts to define it universally.<\/p>\n

Nonetheless, the NIST provided the following definition<\/strong>:<\/p>\n

Digital identity is the online persona of a subject. […] Digital identity is the unique representation of a subject engaged in an online transaction.<\/em><\/p><\/blockquote>\n

Actually, digital identities are not used in the digital realm only. That’s why this definition might not be comprehensive.<\/p>\n

In fact, according to the\u00a0 World Bank<\/a>, digital identity (digital ID) systems are:<\/p>\n

central registries storing personal data in digital form and credentials that rely on digital, rather than physical, mechanisms to authenticate the identity of their holder<\/em>.<\/p><\/blockquote>\n

Within the European context, the European Union<\/a> has also defined digital identity as follows:<\/p>\n

A digital identity is a digital representation of a natural or legal person. It lets you prove who you are during interactions and transactions. Attributes contain information about a subject. This can include details such as your legal name or date of birth, as well as details from other organisations, such as your professional qualifications, bank balance or medical history.\u00a0<\/em><\/p><\/blockquote>\n

The Digital Identity Observatory of the Politecnico di Milano provides another definition of what Digital Identity<\/a> is:<\/p>\n

Digital identity is a set of data that uniquely identifies a person, company, or object. These data are collected, stored, and shared digitally within an ecosystem of actors and through enabling technologies. Digital identity allows access to value-added digital services.<\/em><\/p><\/blockquote>\n

To sum up, we could say that a digital identity is a collection of electronically stored info <\/strong>about an individual or an organization, mirroring an individual’s real-world identity<\/strong>.
\nThe importance of digital identity lies in its critical role in providing security<\/strong>, enabling inclusivity in the digital ecosystem, and fostering trust among users and service providers.<\/p>\n

What are the key components of a digital identity?<\/strong><\/h3>\n

Digital identity comprises unique attributes,<\/strong> credentials, or other distinguishing elements associated with those identities. Key components<\/strong> of a digital identity include personal identification information<\/strong> (like name, date of birth, social security number, biometrics), access credentials<\/strong> (like usernames, passwords), and digital certificates<\/strong>, which act as the online equivalent of different forms of physical ID.<\/p>\n

Which are the most common identifiers?<\/strong><\/h3>\n

Generally, the most common identifiers<\/strong>, meaning a set of attributes that allows an application domain to link the declared identity to a digital entity previously known to the system, can vary depending on the resources that we want to access. However, in general, the most common ones are the following:<\/p>\n
