OpenMined is a community focused on building open-source technology for the decentralized ownership of data and intelligence.It is commonly believed that individuals must provide a copy of their personal information in order for AI to train or predict over it. This belief creates a tension between developers and consumers. Developers want the ability to create innovative products and services, while consumers want to avoid sending developers a copy of their data. With OpenMined, AI can be trained on data that it never has access to. The mission of the OpenMined community is to make privacy-preserving deep learning technology accessible to consumers, who supply data, and machine learning practitioners, who train models on that data. Given recent developments in cryptography, AI-based products and services do not need a copy of a dataset in order to create value from it. The OpenMined ecosystem incorporates a number of technologies including federated machine learning, blockchain, multi-party computation, and homomorphic encryption.
