# Decentralized vs Self-Sovereign Identity

Decentralized and self-sovereign identities are closely related concepts, but they have some nuanced differences.

| <p>A self-sovereign identity is a specific approach within a decentralized identity that emphasizes individual control and ownership over personal identity data. <br><br>Self-sovereign identity can be seen as a more advanced and user-centric manifestation of decentralized identity, emphasising privacy and autonomy.</p> | <p>Decentralized identity refers to implementing the SSI concept that supports managing identity in a decentralized manner by distributing ownership and access control through the different actors in the data verification transaction. </p><p>It reduces reliance on centralized identity and provides access to relevant data according to each party's needs. </p><p>Decentralized identity has been tested through different designs and implementations; TNG makes every effort to align with specifications approved and developed by W3C and EIDAS frameworks. </p> |
