# 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> |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.teranode.group/tng-identity-documentation/self-sovereign-identity-knowledge/decentralized-vs-self-sovereign-identity.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
