# Data Management and Security

### Data Handling 

* **Encrypted Storage and Transfe**r: Data is encrypted at rest and in transit, ensuring that sensitive information is always protected. Encryption keys are managed through decentralized key management systems.
* **Access Contro**l: Access to data is strictly controlled through smart contracts, which verify the credentials of the requestor before allowing access to the data. This ensures compliance with data privacy regulations.

### Privacy-Preserving Technologies

* **Homomorphic Encryption**: Allows computations to be performed on encrypted data, providing results without ever exposing the underlying data.
* **Zero-Knowledge Proofs**: Enable one party to prove to another party that they know a value (e.g., a credential is valid) without conveying any information apart from the fact that they know the value.

### Auditing

* All interactions with AI models and data are logged on the blockchain, providing a transparent audit trail that enhances security and trust in the platform.
