In a nutshell, Self-Sovereign Identity allows individuals to manage their own identities by moving physical credentials to digital devices. An individual will receive a credential from an issuer which will be stored in their digital wallet.

> The technical name for the model at work here is called the Direct Presentation model. A credential is issued, and then held for a long period of time with intermittent voluntary presentations to many different verifiers. To put that back into our example, my auto club issues me a card, which I hold in my wallet for years (maybe decades!), and I might choose to show that card to a garage when I need a tow, or possibly to a store to get a discount.

However, in practice, decentralized identity has only existed for a handful of years, and its potential is still being discovered. So how did we get here?

Decentralized Identity provides a solution for the increasing amount of database breaches, the lack of trust in any digital setting, and the increasingly difficult to comply with privacy legislation, such as GDPR.

> In this research, one of the leading experts and thought leaders in the digital identity space brings his latest thinking to enterprise innovators. He explains the value of the relationship view of identity, the nature of authentic digital relationships, the trust bases of identity systems, and the architecture of the identity metasystem, including decentralized identifier communication and the self-sovereign Internet. He then explores how to operationalize digital relationships and the potential of generative identities (e.g., verifiable credentials) and credential exchange. He concludes with a deep dive into self-sovereign identities in production: the UK National Health Service staff passport, Bonifii’s MemberPass for credit unions, the International Air Transport Association Travel Pass, and others. The project is a must-read for enterprise leaders looking to understand their opportunities in identity platforms and applications.

> This paper analyses the SSI paradigm's conceptual characteristics and technical aspects and presents three use cases as examples. It becomes clear that SSI offers advantages in individual control, data security, and full portability of identities between different services. For example, forgeryand tamper-proof digital versions of important personal documents such as ID cards, passports, birth certificates or medical confirmations can be created. However, the use cases are not limited to personal SSI but can also be, for example, digital identities of organizations and physical objects in the context of IoT solutions. This is particularly important in connection with the comprehensive digitization of companies.
