Self-Sovereign Identity

Cryptographically secure identification records allow users to control third-party transmissions and visibility of personal data. Based on the blockchain, this solution could help individuals to regain ownership of their own data, as it would serve as a single personal identity.

Self-Sovereign Identity

Self-Sovereign Identity (SSI) is a digital identity management system that enables individuals to have control over their own personal data and digital identities without relying on third-party intermediaries. It provides users with a decentralized, secure, and portable identity that can be used across various digital platforms and services.

SSI technology is based on blockchain and distributed ledger technology, which enables users to create a unique digital identity that is cryptographically secured, verifiable, and tamper-proof. The system uses a public-private key pair to encrypt and sign data, allowing users to share their personal information selectively and securely.

In this system, users have complete control over their own data, including what information is shared, with whom, and when. This is in contrast to traditional identity systems, where users often have to provide their personal information to centralized authorities, such as governments or corporations, who then control and manage it on behalf of the user.

This technology solves several problems related to traditional identity systems, including data breaches, identity theft, and loss of control over personal data. With an SSI, users can choose to share only the necessary information required for a specific transaction without giving access to their entire identity. This minimizes the risk of data breaches and identity theft, as well as the collection and misuse of personal data by third-party intermediaries.

SSIs also enable individuals to have greater privacy and control over their personal data, which is particularly important in today's digital age, where data is often harvested, analyzed, and sold without the user's knowledge or consent. SSI systems can also be used to create digital identities for individuals who do not have access to traditional identity documents, such as refugees or people living in underdeveloped regions.

Future Perspectives

Through a combination of encrypted identity and digital identity removal, it could be possible for someone to have their identity wholly protected. For this technology to function properly, it would have to be accepted across a variety of websites and institutions; this might prove to be difficult, as many of them actually profit from the shared data of their user base.

While ‘classical’ human identity has kept philosophers busy since millennia, ‘Digital Identity’ seems primarily machine related. Telephone numbers, E-Mail inboxes, or Internet Protocol (IP)-addresses are irrelevant to define us as human beings at first glance. However, with the omnipresence of digital space the digital aspects of identity gain importance. In this submission, we aim to put recent developments in context and provide a categorization to frame the landscape as developments proceed rapidly. First, we present selected philosophical perspectives on identity. Secondly, we explore how the legal landscape is approaching identity from a traditional dogmatic perspective both in national and international law. After blending the insights from those sections together in a third step, we will go on to describe and discuss current developments that are driven by the emergence of new tools such as ‘Distributed Ledger Technology’ and ‘Zero Knowledge Proof’. One of our main findings is that the management of digital identity is transforming from a purpose driven necessity towards a self-standing activity that becomes a resource for many digital applications. In other words, whereas traditionally identity is addressed in a predominantly sectoral fashion whenever necessary, new technologies transform digital identity management into a basic infrastructural service, sometimes even a commodity. This coincides with a trend to take the ‘control’ over identity away from governmental institutions and corporate actors to ‘self-sovereign individuals’, who have now the opportunity to manage their digital self autonomously. To make our conceptual statements more relevant, we present several already existing use cases in the public and private sector. Subsequently, we discuss potential risks that should be mitigated in order to create a desirable relationship between the individual, public institutions, and the private sector in a world where self-sovereign identity management has become the norm. We will illustrate these issues along the discussion around privacy, as well as the development of backup mechanisms for digital identities. Despite the undeniable potential for the management of identity, we suggest that particularly at this point in time there is a clear need to make detailed (non-technological) governance decisions impacting the general design and implementation of self-sovereign identity systems.

After introducing key concepts and definitions in the field of digital identity, this paper will investigate the benefits and drawbacks of existing identity systems on the road towards achieving self-sovereign identity. It will explore, in particular, the use of blockchain technology and biometrics as a means to ensure the “unicity” and “singularity” of identities, and the associated challenges pertaining to the security and confidentiality of personal information. The paper will then propose a model of blockchain-based self-sovereign identity based on attestations, claims, credentials and permissions, which is globally portable across the life of an individual. Such a system is not dependent on any particular government or organization for administration or legitimacy, although it might include government issued identification and biometrics as one of many indicia of identity.
