Self-sovereign identity (SSI)

Self-sovereign identity (SSI) is an approach to digital identity that gives individuals ownership and control of their digital identities and how their personal information is shared and used. Current implementations of the concept typically involve blockchain.

Frequently asked questions

How do you create a self-sovereign identity?

Self-sovereign identity (SSI) is the idea that individuals should own and control their digital identities — not organizations. To create an SSI, users present their credentials to a trusted third party, which verifies that the credentials came from an issuer they trust, creating a “trust triangle.”

What is self-sovereign identity blockchain?

Self-sovereign identity (SSI) blockchain leverages the shared public ledger framework of blockchain to secure user identities. As the name implies, each transaction or “block” is recorded in a connected chain that is visible to all blockchain users. This makes alterations virtually impossible without detection, in turn providing a clear and auditable trail of identity data permissions.

What is SSI authentication?

While self-sovereign identity (SSI) offers increased control over identity data and permissions for users, it still requires an additional layer of authentication to confirm identity. Here, multi-factor authentication (MFA) solutions such as authenticator apps and biometric scans can help companies confirm user identity data.
