We survey different approaches to Decentralized Identifiers (DIDs) for managing Self-Sovereign Identity (SSI). This kind of identification is used to give full control of identity to end-users by means of a distributed ledger, without the use of a centralized authority that manages the identity of users. We first describe SSI and then DIDs, by summarizing their characteristics. We list the different format implementations of these digital identities by reporting the type of verifiable data registry on which they are based on. We also report the document status od DIDs, the link to their description, and date of creation and update, with the purpose of understanding how much these projects are popular. Finally, we show which and how many of these DIDs are based on public or non-public ledgers.

Abstract
We survey different approaches to Decentralized Identifiers (DIDs) for managing Self-Sovereign Identity (SSI). This kind of identification is used to give full control of identity to end-users by means of a distributed ledger, without the use of a centralized authority that manages the identity of users. We first describe SSI and then DIDs, by summarizing their characteristics. We list the different format implementations of these digital identities by reporting the type of verifiable data registry on which they are based on. We also report the document status od DIDs, the link to their description, and date of creation and update, with the purpose of understanding how much these projects are popular. Finally, we show which and how many of these DIDs are based on public or non-public ledgers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
