Decentralized identity management ensures that AI model creators are authenticated and verified through:

1. _Self-Sovereign Identity_ (SSI): Creators have full control over their digital identity.

2. _Decentralized ID_ (DID): Creators have a unique, decentralized identifier.

3. _Verifiable Credentials_ (VC): Creators can share verified credentials, like qualifications and expertise.

4. _Reputation Systems_: Creators' reputation and trustworthiness are transparent and visible.

5. _KYC (Know Your Customer)_: Creators undergo identity verification, ensuring compliance with regulations.

6. _Biometric Authentication_: Creators use biometrics, like facial recognition or fingerprints, to authenticate.

7. _Smart Contracts_: Creators' identity and credentials are linked to smart contracts, ensuring accountability.

8. _Decentralized Oracle Services_: Creators' identity and credentials are verified by decentralized oracle services.

By implementing these measures, decentralized identity management ensures that AI model creators are authentic, verified, and trustworthy, maintaining the integrity of the AI marketplace.
