# IoTeX Decentralized Identity Overview
This document is a work in progress draft. Last updated at 5 Aug 2020.
Self-sovereign identity is user- and device-centric where an individual or organization or device is able to own its own identity attributes without relying on third-party service providers. Decentralized Identifiers (DIDs) are a new type of identifier for verifiable 'self-sovereign' digital identity for individuals, organizations and things. DIDs have the following important properties:
- Decentralized: DIDs are designed to function without a central registration authority. DIDs are registered in blockchain or other decentralized network.
- Cryptographically Verifiable: DIDs are designed to be associated with cryptographic keys and the entities controlling the DID can use those keys to prove ownership.
- Non-Reassignable: DIDs should be permanent, persistent, and non-reassignable.
- Resolvable: DIDs are made useful through resolution.
IoTeX DID has been integrated by uniresolver.io (opens new window) which is the industrial de facto that resolves DID to the corresponding document
This section provides specification of how DID works within IoTeX Network.
