HumanAI comes from a series of research projects at top universities like MIT and ETH Zurich. It is a decentralized data exchange system that protects and monetizes personal data to enable global user-centric artificial intelligence. It aims to solve the problem that consumers embrace benefits of AI but meanwhile worry about misuse and leakage of personal data. HumanAI leverages edge-computing and blockchain technologies to give consumers full protection and control of personal data. Instead of sending data to AI, HumanAI keeps data on-device and ships AI models to data. Both data and model are encrypted to keep privacy for all stakeholders in the system. Furthermore, HumanAI helps consumers get rid of data brokers and monetize personal data directly in a privacy-preserving way.
