Question: Can you recommend a system that enables me to monetize my data while maintaining ownership and privacy?

If you're looking for a system that lets you monetize your data while keeping ownership and privacy, Ocean is a good choice. It lets you monetize AI models and data through tokenized data and Datatokens. It has customizable access controls and Data NFT encryption, decentralized data marketplaces and prediction bots, and tools like Ocean.js and NewUploader UI to help you build decentralized data-driven apps.

Another good choice is DL3ARN, which centralizes data management with NFTs that house encrypted documents. It offers strong security, verification and traceability so you can be sure data is protected and private. The service offers decentralized data storage and a flexible SDK for businesses that need to transfer data without sacrificing privacy.

ROQ is also worth a look, particularly if you're building multi-tenant SaaS apps. It's got mechanisms for secure database queries, user authentication, role-based access control and monetization through Stripe integration. That lets you get secure and scalable apps up and running with complex data models.

If you're interested in digital ID credentials and verification, Dock is a good option. It lets you create reusable digital ID credentials with immediate verification and monetization abilities. It's based on W3C open standards, so it's designed to ensure data privacy compliance and support multiple digital wallets. That makes it a good fit for many industries.
